THE SHARKS |
Extinct Mackerel Shark Age - Eocene Commonality - Very uncommon
Xiphodolamia ensis, also know as the extinct mackerel shark was a
deep water dweller that lived during the Eocene. These teeth are scarce
worldwide, and in North America are only found on the east coast. The
anterior teeth of Xiphodolamia ensis are unique in that the
cutting edge is on the labial and sometimes lingual side of the crown.
The lateral teeth posse a triangular shaped crown with a distinct root
which is highly compressed and slopes back from the lingual side of the
tooth. Finding these teeth in NJ falls somewhere between uncommon and
scarce.
