Unstable taxa and epochs in coelurosaurus: A new dromaeosaur from an early Cretaceous Yixian Formation

The scarcity of fossils has helped fill in gaps in early bird evolution. Even at their earliest stages, the nearest fossil relatives of birds were evolving in different ways.

Discovery of a late-Jurassic bird-like dinosaur at a site near Nanping in Fujian: A search for a human-like runner with long legs

An R package was used for estimation and inference about allometric lines. Methods Ecol. Evol. 3, 257–259 (2012).

The discovery of an animal in a group of birds is odd, according to a Paleontologist from the University of Utah.

It did not have a lot of modifications that would contribute to flight. It had shorter shoulder and fingers that were better suited for grabbing. The hind legs of the bird have a hyper-elongated leg bone which is twice as long as the thigh bone. Bhart-Anjan Bhullar believes that long legs are a sign of a highly skilled runner and is associated with a roadrunner.

It was a stroke of luck that the dinosaur was found at all. Researchers uncovered the fossil at a site near Nanping in Fujian province, where no dinosaurs have been found before. And examples of late-Jurassic bird-like dinosaurs are rare because their hollow bones are fragile and preserve less well. The ideal conditions for fossilization are no oxygen and a lack of decay.

There are many things left to be discovered. We have only just scratched the surface of the animals’ lifestyles.
