frankh8147 Posted July 15, 2018 Share Posted July 15, 2018 Hello! I found this weird fossil yesterday in the Big Brook area of Momouth County New Jersey (Cretaceous). I was thinking possible echinoid but haven't found any like this in the area. Anyone know what it is? As always, thanks in for advance for the help! -Frank Link to comment Share on other sites More sharing options...
Fossildude19 Posted July 15, 2018 Share Posted July 15, 2018 Maybe a crab carapace, Frank? EDIT: By the way, this is an excellent find! You are killing it down in the creeks this year! EDIT#2 : Maybe @MB will have some insight to this.

That's what I was thinking (and honestly hoping for) when I first found it. My main reservation was that it would be pretty ornamental for a crab but some pictures I've found online do seem match up.

frankh8147 Posted July 15, 2018 Author Share Posted July 15, 2018 It matches up very nicely to Cretaceous crabs I'm seeing online from Texas (can't find one with the exact ornamentation but I'm looking). Thanks so much everyone, I've never found one of these before! Link to comment Share on other sites More sharing options...
erose Posted July 15, 2018 Share Posted July 15, 2018 If that is a crab carapace, and it really looks like a good possibility, then it is an excellent find. I would look at maybe consolidating the matrix with Paleobond or something similar. Since I moved out here from the east coast several of my New Jersey specimens have dried out and crumbled...

Thanks! I used a mix of 1/3 Elmers Glue, 2/3 water which was recommended to me by several long time New Jersey collectors so hopefully it does the trick. It has worked well up to this point. I'm pretty sold on crab carapace at this point. Here is a different angle of mine to compared to one I found online - looks like a match to me! Obviously it's a different species but the front part looks really similar. Link to comment Share on other sites More sharing options...

It's definitely one of my favorite recent finds. I wonder what it's claws looked like; every claw I've personally seen that has come from Big Brook has been ID'd as either ghost shrimp or hoploparia gabbi but who knows how many types of crab were here also... I'm thinking maybe the generic 'crustacean' label might fit my collection better for most of my isolated claws. Link to comment Share on other sites More sharing options...
FossilDAWG Posted July 16, 2018 Share Posted July 16, 2018 That is a fantastic specimen! I don't recognize the species, so I suspect it's a rare one and likely of scientific significance. Don Link to comment Share on other sites More sharing options...
brad hinkelman Posted July 16, 2018 Share Posted July 16, 2018 No expert here frank,but looks alittle like a spider crab,I believe a spider crab fossil was found in sandy hook N.J. , but again no expert here. Link to comment Share on other sites More sharing options...

Thanks Brad. I think it probably is some type of spider crab. Edit- @brad hinkelman do you by any chance have any information on the one that may have been found at Sandy Hook?

Carl Posted July 17, 2018 Share Posted July 17, 2018 Absolutely a crab! And a damned fine one. Crazy rare. Run this by Ralph Johnson - he'll know what it is. Even though I know nothings about crabs I'm going to guess Necrocarcinus. Well done! Link to comment Share on other sites More sharing options...

I was just talking about you to another fossil hunter the other day - I said in the cold winter months you are one of the only other collectors I run into who is crazy enough to be in the streams (one of the best compliments I can give ).

FossilDAWG Posted July 17, 2018 Share Posted July 17, 2018 My best guess is Chondromaia antiqua Feldmann et al 2013. This new genus and species was described by Feldmann and coworkers in 2013 based on a fragmentary specimen from the Mt Laurel on Hopp Brook. If my ID is correct your specimen is far better than the unique holotype. Don Reference: Feldmann RM, Schweitzer CE, Baltzy, LM, Bennett OA, Jone AMR, Mathias FF, Weaver KL, and Yost SL. New and previously known decapod crustaceans from the Late Cretacous of New Jersey and Delaward, USA. Bulletin of the Mizunami Fossil Museum, no. 39 (2013), p. 7–37.
