Dinosauromorpha is a clade of avemetatarsalians (archosaurs closer to birds than to crocodilians) that includes the Dinosauria (dinosaurs) and some of their close relatives. It was originally defined to include dinosauriforms and lagerpetids, [3] with later formulations specifically excluding pterosaurs from the group. [4]
tr This is a list of stratigraphic units from which dinosaur body fossils have been recovered. Although Dinosauria is a clade which includes modern birds, this article covers only Mesozoic stratigraphic units. Units listed are all either formation rank or higher (e.g. group).
Dinosaurs are unique in showing a perforate or open acetabulum, where the full extent of the socket is a hole without infilling bone. [1] acromion The acromion is a bony ridge on the lower part of the scapula that functions in providing an attachment for the clavicle.
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 .

What type of dinosaur it belonged to is unknown, but there have been suggestions that it was from Allosaurus. "Beelemodon": Known only from two teeth found in Wyoming. They share features of compsognathids, dromaeosaurids and basal oviraptorosaurs. "Capitalsaurus": The official dinosaur of the District of Columbia. It is known from a single ...
Rebuilding a complete skeleton by comparing the size and morphology of bones to those of similar, better-known species is an inexact art, and reconstructing the muscles and other organs of the living animal is, at best, a process of educated guesswork.
