The other included "Teratosaurus" minor, "Sellosaurus" fraasi, and "Palaeosaurus" diagnosticus. Efraasia was the oldest valid generic name for these fossils. The specific name could not be determined as simply, as both Teratosaurus minor and Sellosaurus fraasi had first appeared in von Huene's 1908 book.
Plateosauridae is a family of plateosaurian sauropodomorphs from the Late Triassic of Europe, Greenland, Africa and Asia. [1] [2] Although several dinosaurs have been classified as plateosaurids over the years, the family Plateosauridae is now restricted to Plateosaurus, Yimenosaurus, Euskelosaurus, and Issi [3].
Estimates from the existing fossil material measure this dinosaur at about 12.2 m (40 ft) in length and 7 t (7.7 short tons) in weight. [13] With such parameters it was the largest of the non-sauropod ("prosauropod") sauropodomorphs [ 13 ] until the discovery of Lishulong , with 13 meters in length.
The closest is the Dinosaur Genera List, compiled by biological nomenclature expert George Olshevsky, which was first published online in 1995 and was regularly updated until June 2021. [ 1 ] [ 2 ] The most authoritative general source in the field is the second (2004) edition of The Dinosauria .

Thescelosaurus (/ ˌ θ ɛ s ɪ l ə ˈ s ɔː r ə s / THESS-el-oh-sore-us [6]) is a genus of ornithischian dinosaur that lived during the Late Cretaceous period in western North America. It was named and described in 1913 by the paleontologist Charles W. Gilmore; the type species is T. neglectus.
Scientists think that Silesaurus was not a dinosaur, but rather a dinosauriform.Dinosaurian features lacking in Silesaurus include an enlarged deltopectoral crest (a muscle attachment on the humerus), and epipophyses (enlarged tendon attachment above the postzygapophysis) on the cervical vertebrae.
