'Fluffy' dinosaurs?

Apparently, they now have reached the conclusion that some dinosaurs were as fully feathered as modern birds but fluffier due to a different feather formation - interesting, no? Read on.https://www.sciencedaily.com/releases/2 … 230425.htm

There are actually some theories that certain "dinosaurs" actuallly descended from birds.

I might be wrong but, as far as I know, there is only one theory about that. It was based on a single study by a University [I forget which one but it was either Oregon or Ohio, I think] and it had to do with the respiratory system of birds which they claim could not have possibly come from a dinosaur although they did state that, most likely, both birds and the dinosaur they studied [again, memory fails on which one] had a common ancestor so I don’t know how valid this theory is because there is only this one single study… I’ll look for it and come back on this very interesting point, Michael.

I heard another one but basically it was that some of the small theropod dinosaurs of the late Cretaceous were actually flightless birds. And that birds did not descend from them but that they descended from birds (or protoaves). Basically it’s a bit of an anomaly that there are similar to bird ancestors living in the Cretaceous when there is evidence of birds back to the Jurassic. So one theory described their features of being descendent rather than ancestoral. All and all birds and dinosaurs have too much in common.

It was a talk at the NY Paleontological Society about a paper that was not yet published at the time about the analysis of humerus length in theropod dinosaurs showing how the length of the forearm of the more basal species was much too long to be a normal arm. Now believed to be a flightless wing.The lines between birds and dinosaurs are getting blurredHere is a similar conclusion study about a dinosaur being renamed a flightless bird:https://blogs.scientificamerican.com/te … less-bird/

Ahhh, I checked it out and the Balaur seems to be now confirmed under the avialae clade of the theropoda so yes, it appears they were right!PS LOVED the name they chose: Balaur Bondoc, a stocky dragon

Sure. Because birds are dinosaurs. Well, avian dinosaurs, according to paleontologists. And there’s more and more evidence that many dinosaurs had feathers.In excited nerdy discussions with my avian vet, the avian vet told me that chickens are direct descendants from T. Rex.So, birds are descendants and the survivors of the dinosaurs, but they are also modern avian dinosaurs. Which is cool, because… look at the feet, and the eyes! Dinosaur, right there, 'nuff said.
