[25] The Chasmosaurinae usually have long frills, like Chasmosaurus itself, whereas their sister-group the Centrosaurinae typically have shorter frills. due to the lack of the parietal preserved in the holotypes of both. Gewicht: 3,5 Tonnen. 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. These include AMNH 5422, ROM 843 (earlier ROM 5499) and NHMUK R4948, all (partial) skeletons with skull. (2016) as differing from other C. belli referred specimens in having more epiparietals, although the authors interpreted them as individual variation, but this was reconsidered when Campbell et al. Longrich also regarded the holotype of Eoceratops as probably being an exemplar of Mojoceratops. Aug 13, 2019 - This Pin was discovered by Cameroncraigt. [2] The larger scales had a diameter of up to fifty-five millimetres and were distanced from each other by five to ten centimetres. The Ottawa Naturalist 27: 145-155. Am J Sci, series 4 6: 92. wiki/Chasmosaurus Lehman, 1990, "The ceratopsian subfamily Chasmosaurinae: sexual dimorphism and systematics", In: K. Carpenter and P. J. Currie (eds.). A juvenile chasmosaurine ceratopsid (Dinosauria, Ornithischia) from the Dinosaur Park Formation, Alberta, Canada. With the lower DPF species the outer one was the largest, with C. belli the inner one. Paul suggested that the beak was the main defensive weapon. Lambe LM 1914. belli. There are five other cervicals preserved in this specimen, for a total of eight, which likely represents a complete neck. The postcranium of C. belli is best preserved in the specimen known as NHMUK 4948. Like many ceratopsians, Chasmosaurus had three main facial horns - one on the nose and two on the brow. This clade became quadrupedal, developed a large head crest and a variety of horn combinations. The function of the frill and horns is problematic. Triceratops sp. [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. [18] [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. The first three cervical vertebrae are fused into a unit known as a syncervical, as in other neoceratopsians. in 2010. 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. 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. wiki/Triceratops. The species is based on fossils thought by other researchers to belong to Chasmosaurus. 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. [22] The sides were adorned by six to nine smaller skin ossifications (called episquamosals) or osteoderms, which attached to the squamosal bone. This video is unavailable. [8], Charles Mortram Sternberg added Chasmosaurus russelli in 1940, based on specimen NMC 8800 from southwestern Alberta (lower Dinosaur Park Formation). The generic name is derived from mojo and the specific name means "conspicuous pride" in Greek, both referring to the skull frill. It had three medium size horns on its face and many set of horns on the side of its crest. Chasmosaurus sp. Chasmosaurus has a condensed body type, a large rectangular frill, and three horns; one on its snout and two above its eyes. They were hexagonal or pentagonal, thus with five or six sides. 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. The proportions are not so different than the adult, other than the shield, adding doubt to the earlier Triceratops reconstruction. (2019) referred Vagaceratops back to Chasmosaurus. 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". Campbell and colleagues, in their 2016 analysis of Chasmosaurus specimens, agreed with the conclusions of Maidment & Barrett, adding that some supposedly unique features, such as grooves on the parietal bone, were actually also present in the holotype of C. russelli and, to various degrees, in other Chasmosaurus specimens. Unlocked on Isla Pena, Chasmosaurus has average requirements and is otherwise relatively easy to take care of. (2019) interpreted these specimens as an indeterminate Chasmosaurus species closely related to Vagaceratops. 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. Campbell, J.A., Ryan, M.J., Holmes, R.B., and Schröder-Adams, C.J. The shield is small and the fontanelles are smaller. 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. (2016). What the Chasmosaurus was known for was the big frill and its beautiful colors. Like all ceratopsians, it was purely herbivorous. The fossil was complete save for its missing front limbs, which had fallen into a sinkhole before the specimen was uncovered. Cervicals four to eight are amphiplatian, wider than long, and roughly equal in length. The dorsal vertebrae are also amphiplatian. [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". Chasmosaurus Lambe, 1914: Fajok; C. belli (Lambe, 1902 [eredetileg Monoclonius belli]) C. russelli Sternberg, 1940; Hivatkozások A Wikifajok tartalmaz Chasmosaurus témájú rendszertani információt. Watch Queue Queue 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'). The frill of Chasmosaurushas been described as "heart-shaped", since its bone structure is made up of two large 'loops' from a core bone. 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. [8] The latter species, originally Monoclonius canadensis Lambe 1902, had been described as Eoceratops canadensis by Lambe in 1915. [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. Ernährung: Pflanzenfresser. Thomas Lehman described Chasmosaurus mariscalensis in 1989 from Texas,[15] which has now been renamed Agujaceratops. Chasmosaurus kaiseni was then by Longrich regarded as a nomen dubium, rather than as the senior synonym of M. perifania. [2] The specific name honoured collector Walter Bell. Large ridges strengthen the frill. A Wikimédia Commons tartalmaz Chasmosaurus témájú kategóriát. Apr 19, 2019 - Explore Buddyhoot's board "Tyrannosaurus Rex vs. Triceratops" on Pinterest. (Currie et al. Arte de Luis V. Rey. The skin appears to have had large scales in evenly spaced horizontal rows among smaller scales. Chasmosaurus was a medium-size ceratopsid. Name: Chasmosaurus. Each of these sides touched somewhat smaller scales, forming a rosette. perifania. This species was given its own genus, Vagaceratops, in 2010. DOI: 10.1080/02724634.2015.1048348. 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). [20] Specimens referred to C. russelli are all from the lower Dinosaur Park Formation, stratigraphically and morphologically separate from C. Chasmosaurus was in 1915 by Lambe within the Ceratopsia assigned to the Chasmosaurinae. [11] In 1927 C.M. Der Name leitet sich von den griechischen Wörtern chasma (=Loch, Öffnung) und sauros (=Echse) ab und spielt auf die großen Öffnungen im Nackenschild an. 1940 wurde mit C. russelli eine zweite und … The parietal bones of the frill were pierced by very large openings, after which the genus was named: the parietal fenestrae. [2] He erected the new species Monoclonius belli to describe his findings. 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. Sternberg, C.M., 1940, "Ceratopsidae from Alberta". Sternberg was accompanied by skin impressions. The Chasmosaurus is an rhinoceros-like quadrupedal herbivore that inhabits FMM UV-32. Most cladistic analyses show that Chasmosaurus has a basal position in the Chasmosaurinae. The frill of Chasmosaurus is very elongated and broader at the rear than at the front. Chasmosaurus is a member of the Ceratopcean family. It was alive a little bit before the famous dinosaurs like Tyrannosaurus and Triceratops. Marsh OC 1898. All specimens of Chasmosaurus were collected from the Dinosaur Park Formation of the Dinosaur Provincial Park of Alberta, Canada. This was the first chasmasaurine, a ceratopsian, that had longer brow horns than nasal horns. [22] The known differences between the two species mainly pertain to the horn and frill shape, as the referred postcrania of C. russelli are poorly known. The genus name "Diceratops" was preoccupied by a type of hymenopteran insect. With C. belli the rear of the frill is V-shaped and its sides are straight. It would have had skin stretched over the holes in its frill. It may have just used to seem mas… Watch Queue Queue. For the aforementioned reasons, it is likely that Mojoceratops, Eoceratops, and C. kaiseni belong to a distinct species, if not genus, of chasmosaurine. Beitrag #1 russelli. 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 … 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. From top to bottom, the large scale rows gradually declined in size. Chasmosaurus was a dinosaur which lived approximately 67 to 70 million years ago during the late Cretaceous Period. your own Pins on Pinterest It is hardly elevated from the plane of the snout. Not only are Triceratops and Tyrannosaurus Rex the two most popular dinosaurs that ever lived, they were also contemporaries, prowling the plains, creeks, and woodlands of late Cretaceous North America, about 65 million years ago. When threatened, Chasmosaurus will charge and attempt to gore its attacker. 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. [7] This form is perhaps related to Chasmosaurus canadensis ('from Canada') named by Thomas M. Lehman in 1990. belli. Currie PJ, Holmes RB, Ryan MJ and Coy C. 2016. The name Chasmosaurus is derived from Greek χάσμα, khasma, "opening" or "divide" and refers to the very large parietal fenestrae in the skull frill. Chasmosaurus have clawed feet resembling hooves tipping their sturdy legs. A juvenile Chasmosaurus belli found in Alberta, Canada by Phil Currie et al., reveals that Chasmosaurus may have cared for its young, like its relative, Triceratops, is hypothesized to have done. Periode: Kreide. The Chasmosaurus specimen NMC 2245 recovered by C.M. There is no museum number. 06-abr-2014 - Triceratops vs Tyrannosaurus. See more ideas about tyrannosaurus rex, tyrannosaurus, prehistoric animals. [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. Small, non-overlapping convex scales of about one centimetre in diameter surrounded the whole. [21], Today, taxonomy of Chasmosaurus is in a state of flux. Chasmosaurus was the oldest of the long-frilled, horned ceratopsian dinosaurs, whose family includes Triceratops. [18] However, Campbell et al. [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. 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 … Chasmosaurus ( KAZ-mo-SAWR-əs) is a genus of ceratopsid dinosaur from the Upper Cretaceous Period of North America. 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. Chasmosaurus shared its habitat, the east coast of Laramidia, with successive species of Centrosaurus. Note the curved ischium and the ilia extend laterally, provideing the hips a form of armor. T.M. [Galileo] Chasmosaurus vs. Gorgoaurus & [Dinosaurstudio LoRusso] Triceratops 17.09.2013, 23:51 (Dieser Beitrag wurde zuletzt bearbeitet: 19.09.2013 21:03 von Buzzie .) [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. juvenile (below) has an original reconstruction and a new one based on text measurements rather than scale bars. Doch ist die vom Squamosum gebildete knöcherne Nackenkrause von großen, paarigen Öffnungen durchbrochen, worauf der Name "Chasmosaurus" zurückgeht. 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. New species of Ceratopsia. [2] Today some of these are considered to only reflect a morphological variation among the known sample of Chasmosaurus belli skulls;[2] others are seen as valid species of Chasmosaurus or as separate genera. Mojoceratops was named by Nicholas R. Longrich in 2010 and the type species is Mojoceratops perifania. Brown, B., 1933, "A new longhorned Belly River ceratopsian". 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'). Lambe, L.M., 1902, "New genera and species from the Belly River Series (mid-Cretaceous)". An average sized ceratopsian, Chasmosaurus is similar in size to its relatives, Triceratops and Sinoceratops. [16], The most recently described species is Chasmosaurus irvinensis named in 2001,[17] which stems from the uppermost beds of the Dinosaur Park Formation. The remainder of the rear edge lacked osteoderms. The juvenile measured five feet long and was estimated to be three years of age and had similar limb proportions to the adult Chasmosaurus. Specimens AMNH 5656, NMC 34832 and TMP 1979.11.147, and (tentatively) AMNH 5401 and NMC 1254 were also referred to the genus. With the lower DPF species the rear edge is shaped as a shallow U, and the sides are more convex. 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. It had two large openings in its frill, they were used to intimadate. The specific name honours Loris Shano Russell. C. belli possessed a synsacrum, a compound unit composed of sacral, dorsal, and sometimes caudal vertebrae, depending on the specimen.[23]. The juvenile Triceratops (below) has shorter skull features. These were not oval in shape, as with most relatives, but triangular, with one point orientated towards the frill corner. 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. This variability, they argued, strongly suggested that Mojoceratops was simply a mature growth stage of C. Triceratops horridus (Marsh 1889) Late Cretaceous ~70 mya was the last of the ceratopsians. Chasmosaurus had small and blunt horns compared to other ceratopsians, especially the triceratops. Chasmosaurus was also a mecha in the Super Sentai series Bakuryuu Sentai Abaranger and a zord in its American counterpart Power Rangers: Dino Thunder. Chasmosaurus is a genus of ceratopsid dinosaur from the Upper Cretaceous Period of North America. belli."[20]. Chasmosaurus is one of the smaller FMM UV-32 inhabitants, resembling its relative Triceratops. The frill may also have been brightly colored, to draw attention to its size or as part of a mating display. The skull YPM 2016 and the skull and skeleton AMNH 5402 were noted by Campbell et al. This mount from an auction house may be a chimaera or a complete specimen. But, the frill was so large and yet so weak (since most of it was skin stretched between the bones) that it could not have provided much functional defense. [4][12] In 1987, Gregory S. Paul renamed Pentaceratops sternbergii into Chasmosaurus sternbergi,[13] but this has found no acceptance. [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. [4] Based on these finds, Lambe (1914) erected Protorosaurus ("before Torosaurus),[5] but that name was preoccupied by the Permian reptile Protorosaurus, so he subsequently created the replacement name Chasmosaurus in February 1914. The larger scales were wrinkled due to straight grooves orientated perpendicular to their edges. 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.
