3 Giant Beaver Fossil Teeth

Species: Castoroides leiseyorum (Giant Beaver)

Age: Pleistocene epoch, from about 1.5 million years ago to 11,000 years ago.

Found: Florida, USA

Fossil beaver teeth found in Florida primarily belong to the extinct Giant Beaver, Castoroides leiseyorum, which lived during the Pleistocene epoch. These incisors could reach about six inches long and were broader and blunter than modern beaver teeth, suggesting they were used for a diet of softer plants rather than for felling trees.
