Basilosaurus Molar Fossil – Rare and Well Preserved This impressive fossil tooth belongs to Basilosaurus, one of the earliest fully aquatic whales and a dominant predator of ancient seas. The specimen displays strong morphology with clearly defined cusps and well-preserved surfaces, offering an exceptional example of prehistoric marine adaptation. The tooth retains excellent structural detail, highlighting the powerful biting anatomy that enabled Basilosaurus to seize slippery prey such as fish and smaller marine animals. Its natural coloration and surface texture reflect the fossilization process while preserving the original form with remarkable clarity. About Basilosaurus Despite its name meaning “king lizard,” Basilosaurus was not a reptile but a primitive whale that lived during the Eocene epoch (approximately 40–34 million years ago). With its elongated body and formidable jaws, it represented one of the earliest apex predators among marine mammals. Specimen highlights: Distinct cusps and robust tooth structure Strong overall preservation Complete and visually striking fossil A collectible of both scientific and display value This fossil is ideal for collectors, educators, or anyone with an interest in marine evolution, offering a tangible connection to one of the most fascinating chapters in the history of whales.
