Their initial research indicated that the skull bones were fused, and that it therefore represented an adult specimen. The underside of the trunk was covered by eighteen or nineteen pairs of segmented belly ribs. This hypothesis may be supported by biomechanical analysis. [105] The subsequent discovery of the giant species Yutyrannus huali, also from the Yixian, showed that even some large tyrannosauroids had feathers covering much of their bodies, casting doubt on the hypothesis that they were a size-related feature. 2019 Chapter Book List: Books Read and Rated, 2018 Chapter Book List: Books Read and Rated, 2017 Chapter Book List: Books Read and Rated, 2016 Chapter Book List: Books Read and Rated, 2015 Chapter Book List: Books Read and Rated, 2014 Chapter Book List: Books read and rated, 2013 Chapter Book List: Books read and rated.

Poor little Drip: all he wants is a quiet life munching on water weed . As T. rex specimens have been found from Saskatchewan to New Mexico, differences between individuals may be indicative of geographic variation rather than sexual dimorphism.

[181] By far the largest carnivore in its environment, T. rex was most likely an apex predator, preying upon hadrosaurs, armored herbivores like ceratopsians and ankylosaurs, and possibly sauropods. [227][228], In the same paper, it is suggested that in a population of Tyrannosaurus adults numbering 20,000, the number of individuals living in an area the size of California could be as high as 3,800 animals, while an area the size of Washington D.C. could support a population of only two adult Tyrannosaurus.
