Awesome Mosasaur SKULL Fossil mosasaurus Cretaceous period dinosaur bones 16 in
Fossilized mosasaur skull from the Cretaceous era more than 70 million years old. Excellent skull all bones are original. Late Cretaceous (75 - 65 MY). Mosasaurs were a family of enormous marine reptiles that truly dominated the seas 90 million years ago, ruling during the last 20-25 million years of the Cretaceous period. With the extinction of the ichthyosaurs and decline of plesiosaurs, mosasaurs diversified to become prolific apex predators in nearly every habitat of the oceanic world.
Larger mosasaurs were the great leviathans of their time, extending 10-15 meters, or 33-49 feet long. Hainosaurus holds the record for the longest mosasaur at a seemingly impossible 57 feet. The smaller genera were still an impressive 10-20 feet long.
Mosasaurs probably evolved from semi-aquatic scaled reptiles, perhaps more similar in appearance to modern-day monitor lizards. They had double-hinged jaws and flexible skulls much like that of a snake which enabled them to gulp down their prey almost whole. The gruesome unchewed contents of fossilized mosasaur guts have revealed a varied diet of sea birds, ammonites, smaller marine lizards, possibly sharks, and even other mosasaurs. Ammonites were especially crunchy mosasaur treats.
They were abundant in the Cretaceous seas, and some mosasaurs had specialized teeth for the job. Our team takes pride in professional packaging to safeguard the fossils during transit. Our collection boasts top-quality fossils, curated with care and expertise.
