Dinosaurs of 2009.

READ
A tribute to 3 Dinosaurs all discovered/discovered to have feathers this year, all discovered in china. Packed all into 40 seconds.

P.S. This is a factual video and was made to share information more than anything. SO PLEASE SHARE IT WITH OTHER DINO LOVERS.

Heres a brief summary and whats so special about these critters:

Epidexipteryx
A small maniraptorian dinosaur known only from one fossil. It lived 152-162 MYA. Its skeleton shows that it had four long tail feathers, and wore a coat of downy fur. The skeleton measures only 10 inches and it weighed about 164 grams. It also had a long bird-like third finger.

Anchiornis
A small, feathered, Maniraptorian dinosaur. it is very closely related to birds. It was about 13 inches long and lived during the Jurassic/Cretaceous period. Scientists suggest it could probably fly, as it is very similar to Achaeopteryx.

Tianyulong
A tiny Heterodontid Dinosaur of only 70cm (as estimated in the holotype subadult based on Heterodontosaurus.) It is unique because its skeleton shows fragmentary structures that resemble feathers. This confused paleontologists because Heterodontosaurs were once thought to be in no way related to birds, belonging to a group that gave no ancestral link to birds. This strange herbivore lived in the Early Cretaceous, and has small tusks in its mouth. It is also the earliest feathered dinosaur known.

The song is Lunatic Calm by the Jackal.
the above was written by me btw.

Happy Good Friday! ^o^

right, but you're missing the point. They are mostly analogous to proto-feathers (ala Compsognathus), and heterodontosaurs are the first to branch off of ornithischians (in the early jurassic, probably earlier).

This means that some sort of unbranched, hollow, integumentary system was present on the ancestor of BOTH! See why this is so cool? It means at some point, every lineage of dinosaur had some sort of feather-like covering.

nice vid. what the name of the song (music)

[Grimacebot]

Tianyulong didn't really have true feathers because only theropod dinosaurs can have true feathersd and tianyulong was not a theropod.

But it did have a feather like structure on it's body probably 90% related to feathers but not true feathers more like bristle like proto feathers. Only Theropods and birds can have feathers like the other two, and birds are theropods and reptiles too technically.
