Measuring 3.62 inches, this Carcharocles auriculatus tooth is a standout specimen at any size ,the jet black enamel is high-gloss and pristine, the serrations are razor sharp, and both lateral cusplets are fully intact. A custom display stand, made in-house at Fossils Online, is included with your purchase. Carcharocles auriculatus is one of the most coveted fossil shark teeth in the collector world, representing a pivotal chapter in the evolutionary lineage that ultimately led to the giant Carcharocles megalodon. This large megatoothed shark patrolled warm Eocene seas approximately 38 to 48 million years ago, and its teeth are instantly recognized by their robust triangular crown, coarse serrations, and the distinctive serrated lateral cusplets that set them apart from every other shark in the fossil record. Specimens displaying well-developed cusplets with intact serrations are considered the benchmark of quality among serious collectors and paleontology enthusiasts alike. What makes Carcharocles auriculatus especially significant is its place at a critical node in megatooth shark evolution. It descended from the unserrated Otodus obliquus of the Paleocene and Eocene, and it would go on to give rise to Carcharocles angustidens during the Oligocene — which itself evolved into the legendary Megalodon of the Miocene. Owning an auriculatus tooth is owning a piece of that unbroken 60-million-year story, a direct physical link between the earliest giant sharks and the largest predatory fish that ever lived.
