Description: Fossil Xenacanthus tooth. Xenacanthus is a genus of prehistoric sharks. The first species of the genus lived in the later Devonian period, and they survived until the end of the Triassic, 202 million years ago. Fossils of various species have been found worldwide. The features of Xenacanthus were very distinct compared to todays sharks. They were about 3 to 5 feet long, with a maximum length of 6 feet. They had a long dorsal fin that extended down their backs and tails before merging with the anal fin. So they looked more like modern-day eels than sharks. They also are believed to have a similar swimming style to conger eels. In addition, the Xenacanthus had a sizeable dorsal spine that extended from behind its head. The spine extended outwards and could at times be as long as 1-foot long, giving it its name xnos, meaning foreign or alien and akanthos, meaning spine. This tooth is from Oklahoma USA. Permian 270 million years old. Tooth measures approximately 12mm. Case measures 80mm x 55mm x 33mm. You will receive actual piece shown in pictures in display case.
