Longer than the Great White Shark at a staggering 16 feet, the Xiphactinus was the alpha predator of the Late Cretaceous, ripping its prey apart with its fang-like teeth. These enormous fish were likely warm-blooded, an evolutionary adaptation needed to power their massive bodies.

This specimen is a fossilized Xiphactinus vertebra which measures around 1.5" - 3". It is estimated to be around 83,000,000 years old. Each ships in a sturdy carton with a small photo display card. The card serves as the certificate of authenticity and includes information about the specimen on the reverse side.
