Dinosaur Family Tree Reveals Insight Into Rapid Evolutionary Explosion Began much earlier than scientists had expected. some coelurosaurs started shrinking as far back as 200 million years ago—50 million years before archaeopteryx emerged. at that time, most other. Right, a fossil of the ‘earliest bird’ from the collection cared for at the natural history museum. the gradual evolutionary change – from fast running, ground dwelling, bipedal theropods to small, winged, flying birds – probably started about 160 million years ago. it was possibly due to a move by some small theropods into trees in.
Honey Who Shrunk The Dinosaurs Study Traces Dinosaur Evolution Into If birds evolved from dinosaurs via a series of rapid, dramatic mutations that quickly produced a totally different type of animal, then the two groups should plot onto distinctly different parts. Yes, birds are dinosaurs. shaun hurrell interviews dinosaur evolution expert professor roger benson to unearth the latest research on the origin of birds. share via: roger benson’s latest paper features a feathered, chicken sized, bird like dinosaur revealed to have the hearing ability to rival a barn owl – a specialised nocturnal predator. A six mile wide, mountain sized asteroid struck earth and ended the dinosaurs’ reign. but this didn’t mark the end for all dinosaurs. as paleontologists have discovered, modern birds are, in fact, dinosaurs. "i like to say, birds didn't just come from dinosaurs, they are dinosaurs,” remarks dr. donald henderson, paleontologist and curator. June 2, 2015. modern birds appeared to emerge in a snap of evolutionary time. but new research illuminates the long series of evolutionary changes that made the transformation possible. as dinosaurs morphed into birds, they shrank dramatically and adopted a more babylike skull shape. shown left to right: velociraptor, a dinosaur of the class.

After more than 140 million years in charge, the reign of the dinosaurs came to an abrupt end when a huge asteroid strike and massive volcanic eruptions caused disastrous changes to the environment. most dinosaurs went extinct. only birds remained. over the next 66 million years, birds evolved in many ways, which enabled them to survive in lots. The origin of birds. the discovery that birds evolved from small carnivorous dinosaurs of the late jurassic was made possible by recently discovered fossils from china, south america, and other countries, as well as by looking at old museum specimens from new perspectives and with new methods. the hunt for the ancestors of living birds began.
