The Huge Tyrannosaur That Ruled Before T.rex | Tyrannosaurus mcraensis
What dinosaurs were king before T.rex? New research suggests that Tyrannosaurus rex may have had a giant southern ancestor, which has been referred to as Tyrannosaurus mcraensis. This huge tyrannosaur lived in the southern United States 6-7 million years before T.rex, and if it's a new species would weigh over 8 tonnes. Research on the southern population of Tyrannosaurus goes back to the 1980s and has just been added to with a new abstract from SVP 2023, discussing a new giant tyrannosaur species from New Mexico. Is Tyrannosaurus mcraensis valid, or is it just another specimen of Tyrannosaurus rex? Comment and subscribe to join the discussion! Before T.rex, was there another giant theropod that lived in North America?
