Mosasaurs were large marine reptiles that attained a high degree of adaptation to the marine environment and were distributed worldwide. They first appeared at the start of the Late Cretaceous period, around 100 million years ago, and became extinct 66 million years ago, in the Cretaceous-Paleogene extinction event. Many Mosasaurus were large, with the longest specimen recovered, Mosasaurus hoffmannii, being estimated to have been 17 meters long. Paleontological evidence has shown that these animals had double-hinged jaws and flexible skulls, which enabled them to consume a varied diet, including ammonites.
Large Mosasaur Fossilised Tooth
A large Mosasaur tooth embedded in stone and fossilised in excellent condition, with most of the original root and enamel surviving. A crack cuts the tip of the tooth, though the fossil remains intact.
Please note that measurements have been taken including the stone that the tooth is embedded in.
Period: Late Cretaceous
Condition: Fine condition, a crack to the tip of the tooth, which, however, remains intact.
