Sure looks like an Echinoid. ID hopefully soon to follow, cool stuff!

Ooo..... you have a real rarity as far as inverts go from NJ. Echies are few and far between and it seems you have a whole one there. From what I can find I think you have either a Faujasia sp. or Hardouinia sp. I base the ID on this: http://www.state.nj.us/dep/njgs/enviroed/oldpubs/bulletin61-I.pdf but I could be wrong.

sediment looks like the Mt Laurel lag exposed at Big Brook as orange sand in some high exposures. Go upstream and look high in the banks and you may find your echinoids's source rock. Shamalama has the genera. Nice echinoid!

Wow great thanks I was very excited when i got home and really got a chance to look close and see the tiny deatils. Had a terrible time trying to identify.

Excellent find, complete echinoids are few and far between in the NJ area and are an area of research. To get a definite id the top needs to be exposed. A friend who does research in this area has offered to prep the fossil for you so an accurate identification can be made.

Great!Thank you. what would that entail? Never have been able to and would love to get an ID on this echinoid.
