The well known attributes of T. rex (its jaws, legs and overall body design) are often interpreted to be indicative of either a predatory or scavenging lifestyle, and as such the biomechanics, feeding strategies and diet of Tyrannosaurus have ...
The largest species was Tyrannosaurus rex, the most massive known terrestrial predator, which measured over 13 metres (43 ft) in length [2] and according to most modern estimates up to 8.87 metric tons (9.78 short tons) in weight. [3] [4] Tyrannosaurids were bipedal carnivores with massive skulls filled with large teeth. Despite their large ...
The batteries were formed by the teeth growing fast and maturing early, to the point that the pulp cavity of individual teeth—usually filled with cells and connective tissue—were totally filled with dentine before it even erupted. The lack of pulp in the tooth post-eruption means that the tooth was essentially dead and able to be completely ...
