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. Thomas Lehman described Chasmosaurus mariscalensis in 1989 from Texas,[15] which has now been renamed Agujaceratops. 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. Apr 19, 2019 - Explore Buddyhoot's board "Tyrannosaurus Rex vs. Triceratops" on Pinterest. Watch Queue Queue. It had two large openings in its frill, they were used to intimadate. The Ottawa Naturalist 27: 145-155. This video is unavailable. Fundort: Nordamerika. Brown, B., 1933, "A new longhorned Belly River ceratopsian". russelli. The dorsal vertebrae are also amphiplatian. The following cladogram shows the phylogeny of Chasmosaurus according to a study by Scott Sampson e.a. 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. [2] The larger scales had a diameter of up to fifty-five millimetres and were distanced from each other by five to ten centimetres. Chasmosaurus ( KAZ-mo-SAWR-əs) is a genus of ceratopsid dinosaur from the Upper Cretaceous Period of North America. [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. (Currie et al. [20] Apart from the holotype and paratype several additional specimens of C. belli are known. 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). your own Pins on Pinterest Name: Chasmosaurus. Chasmosaurus ist eine Gattung von Vogelbeckensauriern aus der Gruppe der Ceratopsidae innerhalb der Ceratopsia. [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. T.M. It may have just used to seem mas… Lambe LM 1914. 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. Most cladistic analyses show that Chasmosaurus has a basal position in the Chasmosaurinae. A juvenile chasmosaurine ceratopsid (Dinosauria, Ornithischia) from the Dinosaur Park Formation, Alberta, Canada. Chasmosaurus shared its habitat, the east coast of Laramidia, with successive species of Centrosaurus. 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'). Chasmosaurus sp. Chasmosaurus has a condensed body type, a large rectangular frill, and three horns; one on its snout and two above its eyes. The specific name honours Loris Shano Russell. However, the parietal (back margin of the frill) is not preserved, and was restored with plaster based on specimens of Chasmosaurus, which caused confusion among scientists in previous decades, because the parietal bone is critical for determining differences between species in ceratopsids like Chasmosaurus and Mojoceratops. Discover (and save!) 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. With a length of 4.3–4.8 metres (14.1–15.7 ft) and a weight of 1.5–2 tonnes (1.7–2.2 short tons), Chasmosaurus was a ceratopsian of average size. This indicates that Chasmosaurus was not fast moving, and that juveniles did not need to be fast moving either to keep pace with adults. [24] Unfortunately, nothing can as yet be learned about the coloration of Chasmosaurus from the known fossil skin impression samples. Chasmosaurus is a member of the Ceratopcean family. Marsh OC 1898. The skin appears to have had large scales in evenly spaced horizontal rows among smaller scales. The Chasmosaurus specimen NMC 2245 recovered by C.M. Like many ceratopsians, Chasmosaurus had three main facial horns - one on the nose and two on the brow. 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 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 function of the frill and horns is problematic. Beitrag #1 [18] However, Campbell et al. Mojoceratops was named by Nicholas R. Longrich in 2010 and the type species is Mojoceratops perifania. It was first discovered in 1898 by Lawrence Morris Lambe around Alberta, Canada. [8], Charles Mortram Sternberg added Chasmosaurus russelli in 1940, based on specimen NMC 8800 from southwestern Alberta (lower Dinosaur Park Formation). 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. An average sized ceratopsian, Chasmosaurus is similar in size to its relatives, Triceratops and Sinoceratops. C. belli possessed a synsacrum, a compound unit composed of sacral, dorsal, and sometimes caudal vertebrae, depending on the specimen.[23]. Lehman, 1990, "The ceratopsian subfamily Chasmosaurinae: sexual dimorphism and systematics", In: K. Carpenter and P. J. Currie (eds.). 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., 1902, "New genera and species from the Belly River Series (mid-Cretaceous)". The horns are rather short and the frill had such large fenestrae that it could not have offered much functional defense. However, it is difficult to prove any sexual dimorphism. 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. When threatened, Chasmosaurus will charge and attempt to gore its attacker. Sternberg, C.M., 1940, "Ceratopsidae from Alberta". [21], Today, taxonomy of Chasmosaurus is in a state of flux. [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. The genus name "Diceratops" was preoccupied by a type of hymenopteran insect. The larger scales were wrinkled due to straight grooves orientated perpendicular to their edges. [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. 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. [26] However, today the two are referred to different species. belli. Chasmosaurus was a dinosaur which lived approximately 67 to 70 million years ago during the late Cretaceous Period. 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. [11] This has been seen as a junior synonym of C. 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. [18] Large ridges strengthen the frill. Like all ceratopsians, it was purely herbivorous. Some finds have a few small bones, which may have grown from the edge of the frill. Note the curved ischium and the ilia extend laterally, provideing the hips a form of armor. [16], The most recently described species is Chasmosaurus irvinensis named in 2001,[17] which stems from the uppermost beds of the Dinosaur Park Formation. 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 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. 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. The first three cervical vertebrae are fused into a unit known as a syncervical, as in other neoceratopsians. [20] Specimens referred to C. russelli are all from the lower Dinosaur Park Formation, stratigraphically and morphologically separate from C. [8] The latter species, originally Monoclonius canadensis Lambe 1902, had been described as Eoceratops canadensis by Lambe in 1915. They were hexagonal or pentagonal, thus with five or six sides. Chasmosaurus (/ˌkæzmoʊˈsɔːrəs/ KAZ-mo-SAWR-əs) is a genus of ceratopsid dinosaur from the Upper Cretaceous Period of North America. The skull YPM 2016 and the skull and skeleton AMNH 5402 were noted by Campbell et al. Cervicals four to eight are amphiplatian, wider than long, and roughly equal in length. [22] It is possible that the frill was simply used to appear imposing or conceivably for thermoregulation. Aug 13, 2019 - This Pin was discovered by Cameroncraigt. Chasmosaurus was a medium-size ceratopsid. [2] The specific name honoured collector Walter Bell. In 2010 G.S. Ernährung: Pflanzenfresser. Chasmosaurus had small and blunt horns compared to other ceratopsians, especially the triceratops. (2019) referred Vagaceratops back to Chasmosaurus. From top to bottom, the large scale rows gradually declined in size. [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. These include AMNH 5422, ROM 843 (earlier ROM 5499) and NHMUK R4948, all (partial) skeletons with skull. Longrich also regarded the holotype of Eoceratops as probably being an exemplar of Mojoceratops. Campbell, J.A., Ryan, M.J., Holmes, R.B., and Schröder-Adams, C.J. [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. Triceratops sp. Referred specimens of C. russelli come from the lower beds of the formation while C. belli comes from middle and upper beds. Sternberg was accompanied by skin impressions. The corner of the frill featured two larger osteoderms on the parietal bone. Each of these sides touched somewhat smaller scales, forming a rosette. The sharp cheeks do not extend lateraly. For the aforementioned reasons, it is likely that Mojoceratops, Eoceratops, and C. kaiseni belong to a distinct species, if not genus, of chasmosaurine. The proportions are not so different than the adult, other than the shield, adding doubt to the earlier Triceratops reconstruction. [27] Further study of the specimen revealed that juvenile chasmosaurs had a frill that was narrower in the back than that of adults, as well as being proportionately shorter in relation to the skull.[28]. It was alive a little bit before the famous dinosaurs like Tyrannosaurus and Triceratops. This mount from an auction house may be a chimaera or a complete specimen. [9] A 2016 overview of Chasmosaurus found C. kaiseni and Eoceratops to be referable to Chasmosaurus sp. Paul suggested that the beak was the main defensive weapon. [2] He erected the new species Monoclonius belli to describe his findings. Chasmosaurus lived in large herds like Triceratops, unlike Triceratops Chasmosaurus has a flaten peak on its crest. (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. Journal of Vertebrate Paleontology. 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. The postcranium of C. belli is best preserved in the specimen known as NHMUK 4948. It has three horns on its head, two large ones behind its eyes and a smaller one above its parrot-like beak, and a big frill behind and protecting its head. The species is based on fossils thought by other researchers to belong to Chasmosaurus. juvenile (below) has an original reconstruction and a new one based on text measurements rather than scale bars. Sämtliche fossilen Überreste von Chasmosaurus wurden in der Dinosaur-Park-Formation in Alberta (Kanada) gefunden. [25] The Chasmosaurinae usually have long frills, like Chasmosaurus itself, whereas their sister-group the Centrosaurinae typically have shorter frills. [Galileo] Chasmosaurus vs. Gorgoaurus & [Dinosaurstudio LoRusso] Triceratops 17.09.2013, 23:51 (Dieser Beitrag wurde zuletzt bearbeitet: 19.09.2013 21:03 von Buzzie .) It is hardly elevated from the plane of the snout. Tyrannosaurus Rex (13.5m) vs Triceratops (9m) Torosaurus (8.5m) Styracosaurus (8.5m) Pentaceratops (8m) & Chasmosaurus (7.5m). Chasmosaurus is one of the smaller FMM UV-32 inhabitants, resembling its relative Triceratops. It would have had skin stretched over the holes in its frill. It had three medium size horns on its face and many set of horns on the side of its crest. This variability, they argued, strongly suggested that Mojoceratops was simply a mature growth stage of C. [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. [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. With the lower DPF species the outer one was the largest, with C. belli the inner one. This species was given its own genus, Vagaceratops, in 2010. perifania. What the Chasmosaurus was known for was the big frill and its beautiful colors. [7] This form is perhaps related to Chasmosaurus canadensis ('from Canada') named by Thomas M. Lehman in 1990. The frill of Chasmosaurushas been described as "heart-shaped", since its bone structure is made up of two large 'loops' from a core bone. The juvenile Triceratops (below) has shorter skull features. [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. It's inevitable that a hungry T. Rex and a wary Triceratops would have occasionally crossed paths. 2016, juvenile (below) is known from a complete articulated skeleton lacking only the forelimbs. Doch ist die vom Squamosum gebildete knöcherne Nackenkrause von großen, paarigen Öffnungen durchbrochen, worauf der Name "Chasmosaurus" zurückgeht. wiki/Triceratops. Chasmosaurus was in 1915 by Lambe within the Ceratopsia assigned to the Chasmosaurinae. Chasmosaurus have clawed feet resembling hooves tipping their sturdy legs. (2019) interpreted these specimens as an indeterminate Chasmosaurus species closely related to Vagaceratops. Triceratops horridus (Marsh 1889) Late Cretaceous ~70 mya was the last of the ceratopsians. Chasmosaurus was also a mecha in the Super Sentai series Bakuryuu Sentai Abaranger and a zord in its American counterpart Power Rangers: Dino Thunder. With C. belli the rear of the frill is V-shaped and its sides are straight. 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. (2016). [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 remainder of the rear edge lacked osteoderms. There is no museum number. The shield is small and the fontanelles are smaller. These were not oval in shape, as with most relatives, but triangular, with one point orientated towards the frill corner. .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}. : Chasmosaurus 's board `` Tyrannosaurus Rex, Tyrannosaurus, prehistoric animals three!
