Age - Miocene Commonality - Very uncommon - Scarce
The fossil teeth of Alopias superciliosus are the rarest of the three thresher sharks found in Monmouth County, NJ. A. superciliosus is similar to the slightly more common Alopias latidens but is a more slender species. I personally donít find this a striking difference unless youíre comparing examples of the two species side by. A more definitive characteristic of A. superciliosus is the presence of a deep nutrient grove. In A. Latidens this nutrient grove is absent or at best very faint.
