What’s in a Name? The Battle of Baby T. Rex and Nanotyrannus
The New York Times has a story about the debate of juvenile Tyrannosaurus rex vs Nanotyrannus. The debate has continued for years but was recently revived by the potential sale of a “rare juvenile Tyrannosaurus rex skeleton” by the David Aaron gallery. The dispute has produced reams of scientific research and decades of debate, polarizing paleontologists along the way. Now, with dinosaur…

New research shows ‘juvenile’ T. rex fossils are a distinct species of small tyrannosaur
Phys.org has an article about Nanotyrannus lancensis. A paper in the journal Fossil Studies proposes that N. lancensis is a distinct species of tyrannosaur and not a juvenile T. rex. The first skull of Nanotyrannus was found in Montana in 1942, but for decades, paleontologists have gone back and forth on whether it was a…

Two New Appalachian Dinosaurs Discovered
SciNews has a post about two new dinosaurs from Allalachia during the Cretaceous Period. Back in the Cretaceous Period, North America was bisected by the Western Interior Seaway.

Reconstruction of Tyrannosaur Braincases Shows More Variation Than Previously Thought
SciTechDaily has a story about tyrannosaur skulls. Researchers in Canada and Argentina scanned the skulls to reconstruct the braincase of two well-preserved Daspletosaurs. Their research, which found more variation than expected, was published in the Canadian Journal of Earth Sciences. Among the fierce carnivores that lived during the late Cretaceous was a predator named Daspletosaurus. The massive tyrannosaur,…
