What is Dinosaur Classification Overview about?
Skeletons primarily define dinosaurs, with vertebrae forming the main axial elements of their dorsal skeleton. Teeth are often preserved due to their dense bone composition. Skin impressions indicate dinosaurs had reptilian scales, while soft tissues like skin, nails and feathers were composed of keratin. One of the major recent changes in dinosaur studies has been their classification through cladistics, with saurischians forming one of the earliest known clades dating back to the Late Triassic period.
