Transition Fossils - Part 3 Archaeopteryx... is old news

in #fossils9 years ago (edited)

Archaeopteryx made a massive stir when found and its feathers hinted at the link between dinosaurs and birds

There are now at least 8 well preserved and documented specimens of Archaeopteryx or very close relatives.

Reptiles developed a dry skin and scales to enable them to be less dependent on moist conditions than their amphibian predecessors.

Scales were modified to form feathers in birds and hair in mammals.

Archaeopteryx was pretty special for a while but more fossil finds indicate that the feathered Archaeopteryx is not so unique.

In fact, new finds in china are producing a number of feathered dinosaurs.

Yutyrannus Huali is the largest known dinosaur to definitely have had feathers (more downy) and the fact that its related to the famous T-rex makes it all the more mentionable.

Although not as big as T-rex, still a decent size.

Very cool! Giving that many species develop physical formations based on survival needs I'm not surprised at this. I guess the big question is why it has feathers.

They aren't sure yet, but it might have been something that has grown co-opted with other functions, starting with coloured feathers to get mates, insulation and later flight. Chickens are btw the closest we know to T-Rex. Birds are the descendants of dino's.

Very interesting. Thanks for commenting!
