For more than 150 million years, science didn’t notice a small, fast-moving dinosaur that lived in the floodplains of ...

Scientists have proposed a radical reorganisation of the dinosaur family tree, with major implications for our understanding of dinosaur origins and evolution.

The dinosaur family tree may need to be radically rewritten — and even uprooted and replanted elsewhere, a new analysis of about 75 different species shows.

The dinosaur family tree, used by paleontologists and dinosaur buffs for the past 130 years, has just been transformed. In the old family tree, there are two major groups of dinosaurs: the bird ...

The dinosaur family tree has two main branches: the bird-hipped dinosaurs and the lizard-hipped dinosaurs. Paleontologists have built upon this idea for nearly 130 years. Textbook writers know it.

A new analysis rewrites the dinosaur family tree, splitting up long-recognized groups.

By thoroughly comparing 74 early dinosaurs and their relatives, Baron has radically redrawn the two major branches of the dinosaur family tree.

The new dinosaur family revealed this past spring had problematic analyses, making the true dinosaur family tree even more elusive.

"We completely reshape the dinosaur family tree," said study lead author Matthew Baron of the United Kingdom's University of Cambridge. After careful analysis of dozens of fossil skeletons and ...

From a phylogenetic perspective – how the dinosaur family tree branches over time – it is predicted that ornithischian remains should first appear in the fossil record about 225 million years ago.

The dinosaur family tree is about 130 years old, but it may not stand the test of time. Based on a new study of dozens of fossils and tens of thousands of specific anatomical features, scientists ...
