These are some amazing specimens I found in Texas last year in one area of a river that runs through some privately owned land of some friends of Mine. All of them were half buried with the top of the shell downwords in hard River sediment/rock. Looked like a bunch of circles when I discovered them as the river was super shallow that week. A chisel and hammer would pop them right out. I work on cleaning them up from time to time. There's Alot left to do! Hope you all enjoy.

Scapanorhynchus tenaxus Shark Tooth SITE LOCATION: 30 miles north of Tupelo, Mississippi TIME PERIOD: Upper Cretaceous Period (ca 90,000,000 yrs ago) Data: Scapanorhynchus ("Spade Snout") is an extinct genus of shark that lived from the early Cretaceous until possibly the Miocene if S. subulatus is a mitsukurinid and not a sand shark. Their extreme similarities to the living goblin shark, Mitsukurina owstoni, lead some experts to consider reclassifying it as Scapanorhynchus owstoni. However, most shark specialists regard the goblin shark to be distinct enough from its prehistoric relatives to merit placement in its own genus. Scapanorhynchus had an elongated, albeit flattened snout and sharp awl-shaped teeth ideal for seizing fish, or tearing chunks of flesh from its prey. It was a small shark normally measuring about 65 cm, though the largest species, S. texanus, is thought to have reached up to 3 m (10 ft) in length, about the size of a modern goblin shark. The largest tooth ever found is 7 cm near Atlantic Ocean. Kingdom: Animalia Phylum: Chordata Class: Chondrichthyes Order: Lamniformes Family: Mitsukurinidae Genus: †Scapanorhynchus Species: †tenaxus-
