Leptostyrax is an extinct genus of sharks that lived during the Cenomanian epoch of the Cretaceous period. It is believed to be related to sand tiger sharks and could grow up to 30 feet (9 meters).[1]
Description[]
Leptostyrax is believed to have looked like a sand tiger shark, except larger. If Leptostyrax is in fact related to sand tiger sharks, then the Leptostyrax should have small eyes, multiple rows of teeth, and protruding teeth. Leptostyrax is thought to have been 30 feet long.
