Paleontologists released a new report last week showing that the earliest dinosaur ever discovered in North America is from Wyoming. It's a

With a recent radioisotopic analysis of the fossil specimens dating the remains to around 230 million years old, this tiny 'terrible lizard' named Ahvaytum bahndooiveche is now the oldest-known dinosaur from Laurasia, the Northern Hemisphere land mass of the late Paleozoic supercontinent Pangea.

The discovery of Ahvaytum bahndooiveche, a 230-million-year-old dinosaur in Wyoming, reveals dinosaurs existed in the northern hemisphere earlier than believed, challenging past theories. When and how did dinosaurs first appear and spread across the planet over 200 million years ago?

Dinosaurs inhabited the Northern Hemisphere millions of years earlier than scientists previously thought, according to the new research.

Dinosaurs, the colossal creatures that dominated the Earth millions of years ago, have long fascinated scientists and the public alike. Each new discovery not only ignites imaginations but also deepens our understanding of these prehistoric giants.

In an extraordinary paleontological discovery, scientists have uncovered a remarkably well-preserved dinosaur face fossil that includes intact skin. This find provides an unprecedented look into the appearance and biology of these ancient creatures.

A newly discovered dinosaur, uncovered by UW-Madison paleontologists, is reshaping the understanding of prehistoric reptiles.
