While the dinosaurs' modern-day surviving avian lineage (birds) are generally small due to the constraints of flight, many prehistoric dinosaurs (non-avian and avian) were large-bodied—the largest sauropod dinosaurs are estimated to have reached lengths of 39.7 meters (130 feet) and heights of 18 m (59 ft) and were the largest land animals of ...
Skeleton at Wyoming Dinosaur Center A mount of Gastonia viewed from behind to exemplify the sacral shield and plate-like osteoderms on the lateral sides of the anterior of the tail. Kirkland in 1998 placed Gastonia in the Ankylosauridae, more precisely the Polacanthinae. Later, polacanthines were often seen as Nodosauridae.
Another Diplodocus skeleton was collected at the Carnegie Quarry in Dinosaur National Monument, Utah, by the National Museum of Natural History in 1923. The skeleton (USNM V 10865) is one of the most complete known from Diplodocus , consisting of a semi-articulated partial postcranial skeleton, including a well preserved dorsal column.
Bony parts include the skull, the axial skeleton (spine and ribs), and the appendicular skeleton (girdles and limbs). [21] Most of these bones are paired , with a mirror-inverted counterpart on the other side of the body, or unpaired , in which case they usually lie at the body midline and are divided by the latter into two symmetrical halves ...

Dippy is a composite Diplodocus skeleton in Pittsburgh's Carnegie Museum of Natural History, and the holotype of the species Diplodocus carnegii.It is considered the most famous single dinosaur skeleton in the world, due to the numerous plaster casts donated by Andrew Carnegie to several major museums around the world at the beginning of the 20th century.
Initially, Maleev described Talarurus as having four digits on the foot. [1] However, the foot was not found in articulation; the mounted foot is a composite, and three is the more likely number as all other known ankylosaurids show three toes; earlier reports that Pinacosaurus also possessed four are incorrect.
