What were Tyrannosaur Forelimbs Used For?

Tyrannosaurs are among the most famous non-avian dinosaurs, and for readily apparent reasons. Alongside their massive frames and formidable skulls, there is always one element which is noticed and often made fun of more so than probably any other animal in recent history, that being their comparatively tiny arms, which have been a source of much humour ever since the animals were first described. This video will detail the history of the understanding of these structures and what they were used for, allowing for a greater appreciation of them in the process.I hope you enjoy.
