Thermophysiology and Biology of Giganotosaurus: Comparison with Tyrannosaurus

Large carnivorous dinosaurs present many interesting biological and ecological questions. The most important information for understanding the ecology of these dinosaurs is their metabolism and thermal physiology. These factors in conjunction with their body mass determine the quantity of meat these animals needed to consume, how rapidly they grew and behavioral characteristics such as range si...

Correction to 'Estimating maximum bite performance in Tyrannosaurus rex using multi-body dynamics'.

Bite mechanics and feeding behaviour in Tyrannosaurus rex are controversial. Some contend that a modest bite mechanically limited T. rex to scavenging, while others argue that high bite forces facilitated a predatory mode of life. We use dynamic musculoskeletal models to simulate maximal biting in T. rex. Models predict that adult T. rex generated sustained bite forces of 35 000-57 000 N at a s...

Gender-specific reproductive tissue in ratites and Tyrannosaurus rex.

Unambiguous indicators of gender in dinosaurs are usually lost during fossilization, along with other aspects of soft tissue anatomy. We report the presence of endosteally derived bone tissues lining the interior marrow cavities of portions of Tyrannosaurus rex (Museum of the Rockies specimen number 1125) hindlimb elements, and we hypothesize that these tissues are homologous to specialized avi...

Cannibalism in Tyrannosaurus rex

BACKGROUND Tyrannosaurus rex was one of the largest terrestrial carnivores of all time, and consequently its ecology and diet have been the focus of much discussion. However, there is little direct evidence of diet or feeding habits in this species. METHODOLOGY/PRINCIPAL FINDINGS Examination of museum collections has revealed four specimens of Tyrannosaurus rex that bear tooth marks made by l...
