Mosasaurs are an extinct group of large marine reptiles. Before their extinction at the end of the Early Cretaceous period they were the dominant marine predators of their time. Their remains can be found across many parts of the world that were previously prehistoric oceanic landscapes. This fossilized tooth is about 3.5" inches in length and it is encased within a piece of limestone that is approximately 6" x 5" inches.
