Fossil Tooth of Mosasaur: A Cretaceous Marine Reptile

This article presents an analysis of fossilized teeth of mosasaurs (Mosasauridae), apex marine reptiles of the Late Cretaceous period (approximately 70–66 million years ago). The study focuses on tooth morphology, comparing two specimens that exhibit distinct differences in size, shape, enamel thickness and root structure. These morphological traits provide a basis for species identification, particularly Mosasaurus hoffmanni, the largest known species and related genera such as Prognathodon and Platecarpus. The discussion highlights the biological, geological and paleoecological significance of mosasaur teeth, including their occurrence in Maastrichtian strata and their role in reconstructing ancient marine ecosystems. Key genera within Mosasauridae are reviewed to demonstrate evolutionary diversity. Furthermore, mosasaur teeth are considered as museum objects, representing not only natural evidence of prehistoric life but also valuable artifacts in science communication, historical interpretation and cultural imagination, linking paleontology with contemporary knowledge and societal appreciation.
