Lots of tyrannosaur news: Nanotyrannus debate continues (was it its own dinosaur or was it actually T. rex?), plus a new debate about the evolution of another ferocious tyrannosaur, Daspletosaurus. And a fun fact about a baby T. rex you've probably never heard of.

Dinosaur of the day Bistahieversor, a large, powerful, tyrannosaur that lived almost 10 million years before T. rex in what is now New Mexico.

• A new paper considers Nanotyrannus to be a valid genus (separate from Tyrannosaurus)
• Daspletosaurus may not have evolved via anagenesis
• The Children’s Museum of Indianapolis has a new Allosaurus with skin impressions, belly ribs, and evidence of injuries
• Trinity the T. rex will be on display at the Aathal Dinosaur Museum in Zurich, Switzerland for most of 2024
