THE SHARKS

.

The geographic location of where a fossil was found is consider to be one of the most important factors in determining it's age. The geological time period for most collecting sites in New Jersey is well documented (Atlantic Costal Plain - USGS). As an aid to identification, I've divided this section into two time periods, Cretaceous and Tertiary.


CRETACEOUS

Scapanorhynchus texanus are the largest and most frequently encounter Cretaceous
 shark teeth in
New Jersey.

In some cases a genus or species may be present in both the Cretaceous and  Tertiary and I've combined the page.
