The dinosaur of the day: Tarchia
- Ankylosaurid that lived within the Late Cretaceous in what’s now Mongolia
- Tarchia had a broad, low physique and brief, robust legs
- Walked on 4 legs
- Head was lined in armor
- Had osteoderms on the physique, and possibly had a tail membership
- Had spikes on its again
- Tarchia lived within the desert
- In all probability prey for Tarbosaurus
- One Tarchia cranium has tooth marks from Tarbosaurus
- Present in 1970 by a Polish-Mongolian expedition (discovered a cranium)
- Described in 1977 by Teresa Maryanska
- Sort species is Tarchia kielanae
- Identify means “brainy one”
- Genus identify comes from the Mongolian phrase tarkhi
- Had a bigger mind than different comparable ankylosaurs, and that’s why it’s named the “brainy one”
- Species identify is in honor of Professor Zofia Kielan-Jaworowska, who led the expedition that discovered the fossils
- Holotype features a cranium roof, braincase, and components of the rear of the cranium
- Three different specimens had been referred to Tarchia, and included tail vertebrae (together with a part of the tail membership and a scute) and a proper humerus
- Tatyana Tumanova named a second species in 1977, Tarchia gigantea
- Trachia gigantea was initially Dyoplosaurus giganteus (named in 1956 by Maleev)
- In 1987, Tumanova discovered that Dyoplosaurus and Tarchia had been the identical, which made Dyoplosaurus giganteus a senior synonym to Tarchia kielanae
- Most scientists agreed, and the 2 names had been mixed into Tarchia gigantea
- Then Victoria Arbour discovered that Dyoplosaurus giganteus was a nomen dubium (not distinguishable from different ankylosaurs from the identical time in Mongolia), and revived Tarchia kielanae (she discovered {that a} specimen with a tail and membership that was referred to Dyoplosaurus giganteus was totally different from the Dyoplosaurus holotype)
- Arbour additionally discovered that the specimen Tumanova referred to be Tarchia in 1977 was really Saichania (one other ankylosaur from Mongolia), which was nicely preserved and outlined how Tarchia was illustrated and depicted (and altered how we thought Tarchia regarded)
- Arbour discovered that the holotype of Tarchia was much like Minotaurasaurus (named in 2009 by Miles and Miles), and that Minotaurasaurus was a junior synonym of Tarchia
- In 2016, Penkalski and Tumanova discovered that the 1977 specimen that was referred to Tarchia (that Arbour thought was Saichania) had too many variations from Saichania and was really a brand new Tarchia species, Tarchia teresae. In addition they discovered Minotaurasaurus to be its personal genus
- Estimates of the dimensions of Tarchia have been primarily based on Dyoplosaurus giganteus (holotype was one of many largest recognized ankylosaurs), and estimates had been of 26 ft (8 m) lengthy
- Nonetheless, Tarchia kielanae and Minotaurasaurus holotypes are smalle. Gregory Paul estimated in 2010 that Tarchia was about 14.7 ft (4.5 m) lengthy and weighed 1.5 tonnes
