 Fossil "Pseudocarcharias" teeth dating to the Serravallian age (13.6–11.6 Ma) of the Miocene epoch have been found in Italy, and are identical to those of the modern-day crocodile shark.The crocodile shark has a spindle-shaped body with a short head and a bulbous, pointed snout.The eyes are very large and lack nictating membranes (protective third eyelids).
