A new dome-headed dinosaur species was discovered in Montana, a study released this month shows. Researchers discovered the fossils of Brontotholus harmoni, a dome-headed dinosaur in Montana, according to the paper published Oct. 9 in the Zoological Journal of the Linnean Society.

Gov. Josh Stein announced on Thursday the discovery of a new tyrannosaur species, Nanotyrannus, at the North Carolina Museum of Natural Sciences on Thursday.

Scientists at the NC Museum of Natural Sciences have found that what was believed to be a juvenile T.rex skeleton is instead a distant relative, the first of its kind to be found in a full skeleton. Their work has also raised new questions about what is know about that popular predator.

Paleontologists may have discovered when plant-eating dinosaurs evolved their long necks after a new species of sauropodomorph was found in Argentina.

Now, a research team says new evidence resolves the case. The latest clue comes from a complete skeleton — first uncovered in Montana in 2006 — that scientists say identifies the mystery reptile as its own species and not a juvenile Tyrannosaurus rex.

Researchers at the North Carolina Museum of Natural Sciences and N.C. State University say they have settled a long-standing debate in the field of paleontology with the discovery of a new dinosaur species.

A new study by a North Carolina paleontologist in Raleigh is being called "the biggest dinosaur discovery of the decade."

An analysis suggests Nanotyrannus is a separate, smaller dinosaur that lived alongside T. rex, settling a 30-year debate

A new species of dome-headed dinosaur has been found in fossils found in Montana, according to researchers. Paleontologist Catherine Forster breaks down the discovery.
