Orthacanthus Shark Tooth - Permian 280 Myo Fossil, Pre Dinosaur For Sale
ORTHACANTHUS SHARK TOOTH Oklahoma, 280 million years
This Orthacanthus shark tooth was collected in Waurika, Jefferson County, Oklahoma and dates to the Permian period (280 million years).At 20mm this is a large tooth and, whilst a partial specimen, it offers some nice detail. Comes labelled along with a small certificate of authenticity. An affordable and fascinating fossil, suitable for collection or study! About Orthacanthus For a prehistoric shark that managed to persist for almost 150 million years--from the early Devonian to the middle Permian period--not a whole lot is known about Orthacanthus other than its unique anatomy. This early marine predator had a long, sleek, hydrodynamic body, with a dorsal (top) fin that ran almost the entire length of its back, as well as a strange, vertically oriented spine that jutted out from the back of its head. There's been some speculation that Orthacanthus feasted on large prehistoric amphibians (Eryops being cited as a likely example) as well as fish, but proof for this is somewhat lacking.
