Some scientists, notably Dr. Jack Horner<ref>http://news.bbc.co.uk/2/hi/science/nature/3112527.stm</ref><ref>http://www.sfgate.com/cgi-bin/article.cgi?file=/c/a/2001/02/05/MN133208.DTL&type=science</ref> of the Museum of the Rockies in Bozeman, Montana, have put forward the hypothesis that ''Tyrannosaurus'' was exclusively a scavenger. They cite as their evidence the relatively-slow estimated speed of the animal - no more than 15 miles per hour - as well as the small forelimbs and the large olfactory casts made inside their skulls, which indicated a powerful sense of smell.  This may be partially true, since most carnivores today will happily scavenge available meat. However, it probably was not an ''exclusive'' scavenger, as most meat-eaters must also hunt in order to survive. ''Tyrannosaurus''' jaws were also quite adaptive to grabbing live prey. In opposition to the scavenger theory there are several specimens of dinosaur - principally ''Edmontosaurus'' and ''Triceratops'' - in North American museums which show clear bite wounds that have healed over, and tyrannosaur teeth easily fit inside them.<ref>http://animals.howstuffworks.com/dinosaurs/t-rex-predator-or-scavenger.htm/printable</ref><ref>http://www.unearthingtrex.com/pages/rex_behaviour.html</ref>
