Bull Shark - Carcarhinus leucus
Estimated length : three and a half metres (11 feet)
Age : Late Miocene, about 6 million years old
Locality : Venice Beach, Florida
The modern Bull shark is one of the three most dangerous sharks to man. It lives close to the shore and can tolerate brackish and even fresh water. It will eat almost anything that moves. Fossil teeth of Requiem sharks (genus Carcharhinus) are notoriously difficult to identify to a species. Bull sharks have large triangular heavily serrated teeth that can be mistaken for those of a white shark.
