Age - Cretaceous Commonality - Less common
The teeth of C. samhammeri have a smooth lingual enamel surface. The crown is somewhat broad for Carcharias with a single cusplet on each shoulder. There is a strong lingual protuberance and obvious nutrient grove. Lateral teeth have inclined crowns and broad triangular cusplets. These teeth reach a maximum length of about 3/4s of an inch and and are the most common of the Cretaceous sand tigers. C. Samhammeri is a rather plain looking tooth which can easily be mistaken for a small or stream worn Scapanorhynchus texanus.
