Invertebrate FOSSILS OF NJ
Hoploparia gabbi (Pilsbry)
Hoploparia gabbi, also known as a clawed lobster is most often mistaken for the ghost shrimp (Protocallianassa mortoni). The ghost shrimp body has no chitinous material. Only the pincers and claws are found fossilized. The few examples of Hoploparia gabbi that I have seen all seem to have fossilized in a similar position to the one pictured below. This Cretaceous clawed lobster is considered a scarce find, all the specimens I have seen have been encrusted with marl. I can only speculate that once this marl is worn away through stream action the fossil would quickly come apart.
This specimen was found encrusted in marl with only
the tail showing.

The tail bears a rather remarkable similarity to a
