Dinosaurs evolved within a single lineage of archosaurs 232-234 million years ago in the Ladinian age, the latter part of the middle Triassic. Dinosauria is a wellsupported clade, present in 98% of bootstraps. It is diagnosed by many features including loss of the postfrontal on the skull and an elongate deltopectoral crest on the humerus.
In March 2017, scientists reported a new way of classifying the dinosaur family tree, based on newer and more evidence than available earlier. According to the new classification, the original dinosaurs, arising 200 million years ago, were small, two-footed omnivorous animals with large grasping hands. Descendants (for the non-avian dinosaurs) lasted until 66 million years ago.
Note:add whatever dinosaur facts you want, im curious
i was put against my will to do this.
