Shellseeker Posted April 20, 2019 Share Posted April 20, 2019 I was out hunting today at a location that has larger "small" shark teeth. I really like lower hemis and that keeps me coming back. They can be found but are not "common", even here/ I was looking for them, and almost missed this tooth. That "bump" on the left photo is a cusp. Cusp means predator. The tooth is .95 inches long. Because there is only 1 cusp on the tooth, does that help to identify the position in the jaw of this incisor? I could guess at which predator, but would like confirmation from someone who knows.

There are locations on the Internet selling individual fossil Panthera Onca incisors that average between .85 and 1.125 inches and also have a single cusp. As far as I can see, Puma Concolor incisors have no cusp. I have not yet found a decent photo of Panthera Onca dentition that allows me to determine the position of the Cusp in the jaw.

I was in the Peace River Friday and a tributary creek today. I hope you own this specimen. Looks like the cusp is on the inside of incisor position. If your photo is a maxilla, my incisor is I3 upper left.
