[10], Following the original assignment of the holotype and other skulls to Mojoceratops, several teams of researchers published work questioning the validity of this new genus. Some finds have a few small bones, which may have grown from the edge of the frill. [2] He erected the new species Monoclonius belli to describe his findings. perifania. [9] A 2016 overview of Chasmosaurus found C. kaiseni and Eoceratops to be referable to Chasmosaurus sp. When threatened, Chasmosaurus will charge and attempt to gore its attacker. An average sized ceratopsian, Chasmosaurus is similar in size to its relatives, Triceratops and Sinoceratops. The frill of Chasmosaurus is very elongated and broader at the rear than at the front. Cervicals four to eight are amphiplatian, wider than long, and roughly equal in length. Paul, G.S., 1987, "The science and art of reconstructing the life appearance of dinosaurs and their relatives: a rigorous how-to guide", pp 4–49 in: Sternberg, C.M., 1927, "Horned dinosaur group in the National Museum of Canada", A Re-Evaluation of the chasmosaurine ceratopsid genus, "New Horned Dinosaurs from Utah Provide Evidence for Intracontinental Dinosaur Endemism", "Temporal range extension and evolution of the chasmosaurine ceratopsid 'Vagaceratops' irvinensis (Dinosauria: Ornithischia) in the Upper Cretaceous (Campanian) Dinosaur Park Formation of Alberta", "Transitional evolutionary forms in chasmosaurine ceratopsid dinosaurs: evidence from the Campanian of New Mexico", "Revised geochronology, correlation, and dinosaur stratigraphic ranges of the Santonian-Maastrichtian (Late Cretaceous) formations of the Western Interior of North America", "Rare baby dinosaur skeleton unearthed in Canada", "Charting the growth of one of the world's oldest babies: Late Cretaceous Chasmosaurus fills in missing pieces of dinosaur evolution", https://en.wikipedia.org/w/index.php?title=Chasmosaurus&oldid=997862128, Late Cretaceous dinosaurs of North America, Creative Commons Attribution-ShareAlike License, This page was last edited on 2 January 2021, at 16:23. A certain niche partitioning is suggested by the fact that Chasmosaurus had a longer snout and jaws and might have been more selective about the plants it ate. A certain niche partitioning is suggested by the fact that Chasmosaurus had a longer snout and jaws and might have been more selective about the plants it ate. Name: Chasmosaurus. [20], The species Mojoceratops perifania was based on holotype specimen TMP 1983.25.1 consisting of a partial skull including the parietal and from the paratypes TMP 1999.55.292, an isolated lateral ramus of a right parietal, and NMC 8803, central bar and lateral rami of parietals. Mojoceratops was named by Nicholas R. Longrich in 2010 and the type species is Mojoceratops perifania. The larger scales were wrinkled due to straight grooves orientated perpendicular to their edges. The Chasmosaurus specimen NMC 2245 recovered by C.M. It would have had skin stretched over the holes in its frill. Arte de Luis V. Rey. In 2000, George Olshevsky renamed Monoclonius recurvicornis Cope 1889 into Chasmosaurus recurvicornis as its fossil material is likely chasmosaurine;[14] this is a nomen dubium. Lehman, 1990, "The ceratopsian subfamily Chasmosaurinae: sexual dimorphism and systematics", In: K. Carpenter and P. J. Currie (eds.). Paul estimated the length of C. belli at 4.8 metres, its weight at two tonnes; the lower Dinosaur Park Formation species would have been 4.3 metres long and weighed 1.5 tonnes. This indicates that Chasmosaurus was not fast moving, and that juveniles did not need to be fast moving either to keep pace with adults. The Ottawa Naturalist 27: 145-155. Chasmosaurus is a genus of ceratopsid dinosaur from the Upper Cretaceous Period of North America. With C. belli the rear of the frill is V-shaped and its sides are straight. This clade became quadrupedal, developed a large head crest and a variety of horn combinations. belli. Unlocked on Isla Pena, Chasmosaurus has average requirements and is otherwise relatively easy to take care of. [10] Richard Swann Lull in 1933 named an unusual, short-muzzled skull, specimen ROM 839 (earlier ROM 5436) collected in 1926, as Chasmosaurus brevirostris, "with a short snout". 2016, juvenile (below) is known from a complete articulated skeleton lacking only the forelimbs. Chasmosaurus was also a mecha in the Super Sentai series Bakuryuu Sentai Abaranger and a zord in its American counterpart Power Rangers: Dino Thunder. Note the curved ischium and the ilia extend laterally, provideing the hips a form of armor. belli."[20]. juvenile (below) has an original reconstruction and a new one based on text measurements rather than scale bars. Eoceratops and the long-horned Chasmosaurus kaiseni were thought to probably be exemplars of Mojoceratops by Nicholas Longrich,[9] although different teams of researchers have found Mojoceratops to be a synonym of Chasmosaurus russelli. Lambe, L.M., 1914, "On the forelimb of a carnivorous dinosaur from the Belly River Formation of Alberta, and a new genus of Ceratopsia from the same horizon, with remarks on the integument of some Cretaceous herbivorous dinosaurs". Watch Queue Queue The frill of Chasmosaurushas been described as "heart-shaped", since its bone structure is made up of two large 'loops' from a core bone. Doch ist die vom Squamosum gebildete knöcherne Nackenkrause von großen, paarigen Öffnungen durchbrochen, worauf der Name "Chasmosaurus" zurückgeht. C. belli possessed a synsacrum, a compound unit composed of sacral, dorsal, and sometimes caudal vertebrae, depending on the specimen.[23]. The fossil was complete save for its missing front limbs, which had fallen into a sinkhole before the specimen was uncovered. [26] However, today the two are referred to different species. The shield is small and the fontanelles are smaller. Apr 19, 2019 - Explore Buddyhoot's board "Tyrannosaurus Rex vs. Triceratops" on Pinterest. due to the lack of the parietal preserved in the holotypes of both. Chasmosaurus have clawed feet resembling hooves tipping their sturdy legs. The corner of the frill featured two larger osteoderms on the parietal bone. [10] Recently, the referral of Eoceratops, C. kaiseni, and Mojoceratops to C. russelli was considered doubtful as the holotype of C. russelli is actually from the upper Dinosaur Park Formation, according to recent fieldwork. juvenile (below) has an original reconstruction and a new one based on text measurements rather than scale bars. From top to bottom, the large scale rows gradually declined in size. It had three medium size horns on its face and many set of horns on the side of its crest. It was a medium-sized plant-eater that had a long neck frill with large holes in the bone and narrow structures to support the weight of the frill. See more ideas about tyrannosaurus rex, tyrannosaurus, prehistoric animals. The skull YPM 2016 and the skull and skeleton AMNH 5402 were noted by Campbell et al. Chasmosaurus was a dinosaur which lived approximately 67 to 70 million years ago during the late Cretaceous Period. This was the first chasmasaurine, a ceratopsian, that had longer brow horns than nasal horns. [18] However, Campbell et al. Campbell, J.A., Ryan, M.J., Holmes, R.B., and Schröder-Adams, C.J. Marsh OC 1898. Skin impressions were also uncovered beneath the skeleton and evidence from the matrix that it was buried in indicated that the juvenile ceratopsian drowned during a possible river crossing. Chasmosaurus is one of the smaller FMM UV-32 inhabitants, resembling its relative Triceratops. Most cladistic analyses show that Chasmosaurus has a basal position in the Chasmosaurinae. The dorsal vertebrae are also amphiplatian. In 2011, Maidment & Barrett failed to confirm the presence of any supposedly unique features, and argued that Mojoceratops perifania was a synonym of Chasmosaurus russelli. They were hexagonal or pentagonal, thus with five or six sides. The Chasmosaurus is an rhinoceros-like quadrupedal herbivore that inhabits FMM UV-32. Small, non-overlapping convex scales of about one centimetre in diameter surrounded the whole. Chasmosaurus was the oldest of the long-frilled, horned ceratopsian dinosaurs, whose family includes Triceratops. [2] The specific name honoured collector Walter Bell. Brown, B., 1933, "A new longhorned Belly River ceratopsian". Der Name leitet sich von den griechischen Wörtern chasma (=Loch, Öffnung) und sauros (=Echse) ab und spielt auf die großen Öffnungen im Nackenschild an. Diceratops is now officially named "Nedoceratops" (sometimes unofficially "Diceratus"), but it may instead be a species of Triceratops (or the only known skull may belong to a Triceratops individual with a bone growth defect that made it lose its nose horn). The function of the frill and horns is problematic. A newer study compared incidence rates of skull lesions and periosteal reaction in Triceratops and Centrosaurus and showed that these were consistent with Triceratops using its horns in combat and the frill being adapted as a protective structure, while lower pathology rates in Centrosaurus may indicate visual rather than physical use of cranial ornamentation, or a form of combat focused on the body … Sternberg was accompanied by skin impressions. Chasmosaurus shared its habitat, the east coast of Laramidia, with successive species of Centrosaurus. Chasmosaurus Lambe, 1914: Fajok; C. belli (Lambe, 1902 [eredetileg Monoclonius belli]) C. russelli Sternberg, 1940; Hivatkozások A Wikifajok tartalmaz Chasmosaurus témájú rendszertani információt. The sharp cheeks do not extend lateraly. Its name means 'opening lizard', referring to the large openings (fenestrae) in its frill (Greek chasma meaning 'opening' or 'hollow' or 'gulf' and sauros meaning 'lizard'). In 1913, Mr. Lambe found another species of this genus, so he decided to name all of his finds Protorosaurus, but found out the name was used for another a reptile species in the 19th century. Triceratops sp. New species of Ceratopsia. [8], Charles Mortram Sternberg added Chasmosaurus russelli in 1940, based on specimen NMC 8800 from southwestern Alberta (lower Dinosaur Park Formation). [1], In 1898, Lawrence Morris Lambe of the Geological Survey of Canada made at the Berry Creek the first discovery of Chasmosaurus remains, holotype NMC 491, a parietal bone that was part of a neck frill. It was first discovered in 1898 by Lawrence Morris Lambe around Alberta, Canada. Two forms of Chasmosaurus have had different lengths of the horns found on their faces and it has been suggested that they one was male and the other female. Chasmosaurus was a medium-size ceratopsid. belli. Like all ceratopsians, it was purely herbivorous. The juvenile measured five feet long and was estimated to be three years of age and had similar limb proportions to the adult Chasmosaurus. With the lower DPF species the outer one was the largest, with C. belli the inner one. [2] The area conserved, from the right hip region, measured about one by 0.5 metres. The remainder of the rear edge lacked osteoderms. [20][10] This situation is further complicated since C. russelli may not even belong to the genus Chasmosaurus, sharing features with the contemporaneous derived chasmosaurine Utahceratops. Chasmosaurus ( KAZ-mo-SAWR-əs) is a genus of ceratopsid dinosaur from the Upper Cretaceous Period of North America. In 1933, Lull suggested that C. kaiseni, which bore long brow horns, was in fact the male of C. belli of which the females would have short ones. Triceratops sp. 1940 wurde mit C. russelli eine zweite und … in 2010. Chasmosaurus belli (Lambe 1902, 1914; Late Cretaceous, up to 4.2m) is distinct from Triceratops in having short orbital horns and a heart-shaped shield lightened by large fontanelles (distinct from the upper temporal fenestrae). Chasmosaurus (/ˌkæzmoʊˈsɔːrəs/ KAZ-mo-SAWR-əs) is a genus of ceratopsid dinosaur from the Upper Cretaceous Period of North America. russelli. Triceratops horridus (Marsh 1889) Late Cretaceous ~70 mya was the last of the ceratopsians. [22] The sides were adorned by six to nine smaller skin ossifications (called episquamosals) or osteoderms, which attached to the squamosal bone. The specific name honours Loris Shano Russell. [Galileo] Chasmosaurus vs. Gorgoaurus & [Dinosaurstudio LoRusso] Triceratops 17.09.2013, 23:51 (Dieser Beitrag wurde zuletzt bearbeitet: 19.09.2013 21:03 von Buzzie .) [2] The larger scales had a diameter of up to fifty-five millimetres and were distanced from each other by five to ten centimetres. (2016). Most people like this dinosuar because of the horns and the frill. (2019) interpreted these specimens as an indeterminate Chasmosaurus species closely related to Vagaceratops. .mw-parser-output table.clade{border-spacing:0;margin:0;font-size:100%;line-height:100%;border-collapse:separate;width:auto}.mw-parser-output table.clade table.clade{width:100%;line-height:inherit}.mw-parser-output table.clade td.clade-label{width:0.7em;padding:0 0.15em;vertical-align:bottom;text-align:center;border-left:1px solid;border-bottom:1px solid;white-space:nowrap}.mw-parser-output table.clade td.clade-fixed-width{overflow:hidden;text-overflow:ellipsis}.mw-parser-output table.clade td.clade-fixed-width:hover{overflow:visible}.mw-parser-output table.clade td.clade-label.first{border-left:none;border-right:none}.mw-parser-output table.clade td.clade-label.reverse{border-left:none;border-right:1px solid}.mw-parser-output table.clade td.clade-slabel{padding:0 0.15em;vertical-align:top;text-align:center;border-left:1px solid;white-space:nowrap}.mw-parser-output table.clade td.clade-slabel:hover{overflow:visible}.mw-parser-output table.clade td.clade-slabel.last{border-left:none;border-right:none}.mw-parser-output table.clade td.clade-slabel.reverse{border-left:none;border-right:1px solid}.mw-parser-output table.clade td.clade-bar{vertical-align:middle;text-align:left;padding:0 0.5em;position:relative}.mw-parser-output table.clade td.clade-bar.reverse{text-align:right;position:relative}.mw-parser-output table.clade td.clade-leaf{border:0;padding:0;text-align:left}.mw-parser-output table.clade td.clade-leafR{border:0;padding:0;text-align:right}.mw-parser-output table.clade td.clade-leaf.reverse{text-align:right}.mw-parser-output table.clade:hover span.linkA{background-color:yellow}.mw-parser-output table.clade:hover span.linkB{background-color:green}. [11] In 1927 C.M. The name Chasmosaurus is derived from Greek χάσμα, khasma, "opening" or "divide" and refers to the very large parietal fenestrae in the skull frill. The juvenile Triceratops (below) has shorter skull features. Chasmosaurus kaiseni was then by Longrich regarded as a nomen dubium, rather than as the senior synonym of M. perifania. Chasmosaurus is a member of the Ceratopcean family. [4][12] In 1987, Gregory S. Paul renamed Pentaceratops sternbergii into Chasmosaurus sternbergi,[13] but this has found no acceptance. Periode: Kreide. A Wikimédia Commons tartalmaz Chasmosaurus témájú kategóriát. [19] As Fowler and Fowler found Vagaceratops likely to be the sister taxon of Kosmoceratops in 2020, they suggested it should be maintained as a distinct genus from Chasmosaurus, as its placement would probably remain unstable until chasmosaurines are better understood. due to the lack of the parietal preserved in the holotypes of both. Chasmosaurus shared its habitat, the east coast of Laramidia, with successive species of Centrosaurus. In both species these horns are quite short, but with the lower Dinosaur Park species they are somewhat longer, especially the brow horns, and more curved backwards. Tyrannosaurus Rex (13.5m) vs Triceratops (9m) Torosaurus (8.5m) Styracosaurus (8.5m) Pentaceratops (8m) & Chasmosaurus (7.5m). [11] This has been seen as a junior synonym of C. The proportions are not so different than the adult, other than the shield, adding doubt to the earlier Triceratops reconstruction. Discover (and save!) It was alive a little bit before the famous dinosaurs like Tyrannosaurus and Triceratops. [7] This form is perhaps related to Chasmosaurus canadensis ('from Canada') named by Thomas M. Lehman in 1990. The first three cervical vertebrae are fused into a unit known as a syncervical, as in other neoceratopsians. The frill may also have been brightly colored, to draw attention to its size or as part of a mating display. Chasmosaurus lived in large herds like Triceratops, unlike Triceratops Chasmosaurus has a flaten peak on its crest. wiki/Triceratops. Paul suggested that the beak was the main defensive weapon. The following cladogram shows the phylogeny of Chasmosaurus according to a study by Scott Sampson e.a. [2] Although recognizing that his find represented a new species, Lambe thought this could be placed in a previously-known short-frilled ceratopsian genus: Monoclonius. Chasmosaurus sp. [25] The Chasmosaurinae usually have long frills, like Chasmosaurus itself, whereas their sister-group the Centrosaurinae typically have shorter frills. The frill may have been brightly colored too, to draw attention to its size or as part of mating display. Longrich also regarded the holotype of Eoceratops as probably being an exemplar of Mojoceratops. It may have just used to seem mas… DOI: 10.1080/02724634.2015.1048348. Thomas Lehman described Chasmosaurus mariscalensis in 1989 from Texas,[15] which has now been renamed Agujaceratops. Torosaurus ("perforated lizard", in reference to the large openings in its frill) is a genus of herbivorous ceratopsid dinosaur that lived during the late Maastrichtian stage of the Cretaceous period, between 68 and 66 million years ago, though it is possible that the species range might extend to as far as 69 million years ago. Journal of Vertebrate Paleontology. Each of these sides touched somewhat smaller scales, forming a rosette. There is no museum number. Large ridges strengthen the frill. The species is based on fossils thought by other researchers to belong to Chasmosaurus. All specimens assigned to Mojoceratops were collected from the Dinosaur Park Formation (late Campanian, 76.5–75 ma) of the Belly River Group of Alberta and Saskatchewan, western Canada. However, it is difficult to prove any sexual dimorphism. Campbell and colleagues, in their 2016 analysis of Chasmosaurus specimens found Eoceratops and C. kaiseni to be referable to Chasmosaurus sp. [8] The latter species, originally Monoclonius canadensis Lambe 1902, had been described as Eoceratops canadensis by Lambe in 1915. This mount from an auction house may be a chimaera or a complete specimen. Chasmosaurus belli (Lambe 1902, 1914; Late Cretaceous, up to 4.2m) is distinct from Triceratops in having short orbital horns and a heart-shaped shield lightened by large fontanelles (distinct from the … The horns are rather short and the frill had such large fenestrae that it could not have offered much functional defense. The genus name "Diceratops" was preoccupied by a type of hymenopteran insect. All specimens of Chasmosaurus were collected from the Dinosaur Park Formation of the Dinosaur Provincial Park of Alberta, Canada. [16], The most recently described species is Chasmosaurus irvinensis named in 2001,[17] which stems from the uppermost beds of the Dinosaur Park Formation. With the lower DPF species the rear edge is shaped as a shallow U, and the sides are more convex. This video is unavailable. Chasmosaurus had small and blunt horns compared to other ceratopsians, especially the triceratops. [22] It is possible that the frill was simply used to appear imposing or conceivably for thermoregulation. Sternberg concluded that of the two skeletons he had mounted in the Canadian Museum of Nature, the smaller one, NMC 2245, was the male and the larger, NMC 2280, the female. This species was given its own genus, Vagaceratops, in 2010. Its name means 'opening lizard', referring to the large openings (fenestrae) in its frill (Greek chasma meaning 'opening' or 'hollow' or 'gulf' and sauros meaning 'lizard'). Like many ceratopsians, Chasmosaurus had three main facial horns - one on the nose and two on the brow. On Gryposaurus notabilis, a new genus and species of trachodont dinosaur from the Belly River Formation of Alberta, with a description of the skull of Chasmosaurus belli. It had two large openings in its frill, they were used to intimadate. (2019) referred Vagaceratops back to Chasmosaurus. What the Chasmosaurus was known for was the big frill and its beautiful colors. Specimens AMNH 5656, NMC 34832 and TMP 1979.11.147, and (tentatively) AMNH 5401 and NMC 1254 were also referred to the genus. In 1933 Barnum Brown named Chasmosaurus kaiseni, honouring Peter Kaisen and based on skull AMNH 5401, differing from C. belli in having very long brow horns. These were not oval in shape, as with most relatives, but triangular, with one point orientated towards the frill corner. Da das Material von Ceratops, nach dem die Ceratopsidae benannt werden, zu dürftig für eine genaue systematische Bestimmung ist, benannte Lawrence Lambe diese Gruppe 1915 nach Chasmosaurus. [9], The species Chasmosaurus kaiseni, known from specimen AMNH 5401, a nearly complete (but partially restored) skull on display at the American Museum of Natural History, was considered to share features in common with Mojoceratops perifania and therefore was considered a possible synonym. The postcranium of C. belli is best preserved in the specimen known as NHMUK 4948. [3], However, in 1913, Charles Hazelius Sternberg and his sons found several complete "M. belli" skulls in the middle Dinosaur Park Formation of Alberta, Canada. Aug 13, 2019 - This Pin was discovered by Cameroncraigt. He considered it too poorly preserved for a reliable determination, especially as it belonged to a juvenile individual, and regarded it too as a nomen dubium, rather than as the senior synonym of M. Currie PJ, Holmes RB, Ryan MJ and Coy C. 2016. [19] The specimen CMN 2245 was referred to the Vagaceratops-like Chasmosaurus species by Fowler and Freedman Fowler (2020), who noted that "given the similarity between these two specimens (YPM 2016 and AMNH 5402) and CMN 2245, it is not clear why CMN 2245 was left in C. 06-abr-2014 - Triceratops vs Tyrannosaurus. [6], Since that date, more remains, including skulls, have been found that have been referred to Chasmosaurus, and several additional species have been named within the genus. [76-74] It was thought to have been about 5-6 metres long and was characterised by a large frill and three facial horns, one on its nose and above each of its eyes, similar to other ceratopsians. Lambe LM 1914. It was a quadruped with a protruding jaw and three horns on its long face. Chasmosaurus hat, wie Triceratops, paarige Postorbitalhörner und ein unpaares Nasalhorn. The juvenile Triceratops (below) has shorter skull features. Am J Sci, series 4 6: 92. wiki/Chasmosaurus There are five other cervicals preserved in this specimen, for a total of eight, which likely represents a complete neck. [24] Unfortunately, nothing can as yet be learned about the coloration of Chasmosaurus from the known fossil skin impression samples. [20] Specimens referred to C. russelli are all from the lower Dinosaur Park Formation, stratigraphically and morphologically separate from C. Lambe, L.M., 1902, "New genera and species from the Belly River Series (mid-Cretaceous)". [21], Today, taxonomy of Chasmosaurus is in a state of flux. Chasmosaurus was in 1915 by Lambe within the Ceratopsia assigned to the Chasmosaurinae. Lambe now also assigned a paratype, specimen NMC 2245 found by the Sternbergs in 1913 and consisting of a largely complete skeleton, including skin impressions. The generic name is derived from mojo and the specific name means "conspicuous pride" in Greek, both referring to the skull frill. Canadensis ( 'from Canada ' ) named by Nicholas R. Longrich in and.
