File:B-rex teeth.jpg

Description Tyrannosaurus (MOR 1125, “B-rex”) teeth from the lower jaw of this medium-sized skeleton illustrate the extreme range in overall tooth size within one individual. The black scale bar is 5cm long. Above: A smaller posterior tooth from position #14 from the front of the jaw. Below: A larger tooth from position #4 in the same jaw. This demonstrates why shed dinosaur teeth are not a reliable indicator of relative skeletal size and ontogenetic age.
