Nix Draws Stuff

505 notes

Kulindadromeus zabaikalicus, the first known fluffy ornithischian dinosaur. Only officially announced last week, this little 1.5m long (~5ft) Jurassic critter is an incredibly significant find. Until now all known examples of feathered dinosaurs have been members of the theropod branch, but Kulindadromeus is a basal neornithischian, much more closely related to hadrosaurs, ceratopsians and pachycephalosaurs.

Two other ornithischians, Tianyulong and Psittacosaurus, were previously known to have sported quill-like bristles, but this new find is the first example of actual filamentous “dinofuzz” in the group. The fossils of Kulindadromeus preserve three different types of feathery integument — hair-like filaments on the body, downy tufts on the upper limbs, and strange “ribbon-like” feathers on its shins — as well as scaly skin on the tail and lower limbs.

The idea that fuzzy ‘protofeather’-like structures might be ancestral to all dinosaurs (or maybe even deeper in the archosauria) is starting to look increasingly likely…

Filed under art paleoart paleontology kulindadromeus basically the mesozoic was probably much fluffier than we ever imagined dinosaur ornithischian feather ALL the dinosaurs feathers sketchy stuff
