"Was Tyrannosaurus rex an endotherm ("warm blooded")? - a study of pythons and rats in tropical Australia"
By Professor Thomas Madsen (Faculty of Science)
 Whether some (or all) of the spectacular dinosaurs, such as the mighty Tyrannosaurus rex , were endothermic ("warm blooded") or ectothermic ("cold blooded") has been hotly debated among scientists during the last 30-40 years.
In 1986 Robert Bakker, a famous American palaeontologist, published a book entitled "The Dinosaur Heresies" in which he presented data on predator - prey ratios of carnivorous dinosaurs and their prey.
His results suggested that these huge predators must have been "warm blooded".
Since 1989 I have been conducting studies of predator - prey ratios of water pythons and their main prey, the dusky rat, in the Top End of Australia. A summary of the results from my study will be presented, and more importantly do my data support or reject Robert Bakker's hypothesis of dinosaur endothermy?
Reptile expert Brad Walker will also add comment / provide discussion on Prof. Madsen's research.
