Leptostyrax macrorhiza is an extinct shark believed to be related to the sand tiger sharks and grew to 30 feet in length. They lived during the Cretaceous through the early Eocene Epoch (140-55 million years ago).
This specimen is from the phosphate beds of Khourigba, Morocco. The tooth is a symphesial tooth. That means that the tooth comes from the point in the sharks mouth where the two sides of the upper or lower jaws come together. Teeth from this point of the mouth are usually smaller and narrower than the other teeth in the mouth. Also the top of the root will usually be a little more robust than the other teeth in the mouth. And since they only come from those two points in the mouth, they are much rarer than the other teeth. The shark may have many other rows of teeth, but only one row on top and one row on the bottom.
