Hemipristis serra

Hemipristis serra was a Neogene era shark.

Teeth
The teeth of Hemipristis serra are amongst the easiest to identify both to species and tooth position. The spike-like lower anteriors are often mis-identified as being from a Sand tiger shark (Carcharias) due to the narrow blade, thick roots and cusplets, albeit different. Hemipristis serra is a very common find in Miocene deposits and becomes larger though less numerous in the Pliocene. It struggled on until the Pleistocene of Indonesia before vanishing.
