Who was king before Tyrannosaurus? Uzbek fossil reveals new top dino

47

A new dinosaur from the lower Upper Cretaceous of Uzbekistan, Ulughbegsaurus uzbekistanensis, was described from a single maxilla fossil. The research team estimated that this carcharodontosaurian weighed over 1000 kg and measured 7.5–8.0 meters in length, much larger than previously described predators from the same formation. The fossil’s age, location, and co-occurrence with the smaller tyrannosaurid Timurlengia shed light on the transition from carcharodontosaurians to tyrannosaurids occupying the apex predator niche.
