crinus Posted February 17, 2018 Share Posted February 17, 2018 This specimen recently came into my possession with little information. There was a label that said "near Mangyshlak, Kazakhstan". I did some searching and I see nothing like this coming from Kazakhstan. I know there a number of crab experts on this forum so I was wondering if anyone recognizes this specimen. The concretion is like a sandstone. Looks porous. Also, it would not surprise me that the concretion was shaped into a concretions as there are chisel marks on the outside. The matrix looks soft enough to be shaped. However, I can't be sure. Any help is appreciated. Link to comment Share on other sites More sharing options...
fifbrindacier Posted February 17, 2018 Share Posted February 17, 2018 I think @Doctor Mud, could have an idea, at least about the family of your crab.

RJB Posted February 17, 2018 Share Posted February 17, 2018 Looks very much like the Tumidocarcinus crab from New Zealand, but Ive never seen one in rock like that. Also, the face of the crab does not look like a Tumido? Thats about all I can tell you. I know its not much help though. You have nothing for scale? If you can a hold of MB, he would more than likely know what it is. Good luck RB Link to comment Share on other sites More sharing options...

fossisle Posted February 18, 2018 Share Posted February 18, 2018 I think I have seen something like this from Indonesia or China. Galene sp? Cephalopods rule!! Link to comment Share on other sites More sharing options...
abyssunder Posted February 18, 2018 Share Posted February 18, 2018 I've seen specimens sold as Coeloma taunicum from the Oligocene of Mangyshlak, Kazakhstan.

RJB Posted February 18, 2018 Share Posted February 18, 2018 Hmmm... I came back to this thread in hopes of seeing a positive ID. RB Link to comment Share on other sites More sharing options...
crabfossilsteve Posted February 18, 2018 Share Posted February 18, 2018 I agree with Fossisle that it looks like a crab I've seen from Indonesia (Galene?). This one seem a little better preserved than the ones I've seen on-line. 1 Link to comment Share on other sites More sharing options...
crabfossilsteve Posted February 18, 2018 Share Posted February 18, 2018 By the way Joe, I think your crab is perfectly real, it shows the layers of shell mateial although soft. Link to comment Share on other sites More sharing options...
abyssunder Posted February 18, 2018 Share Posted February 18, 2018 There is a species from that locality: C. birsteini, Mangyshlak (Kazakhstan); Oligocene; Ilyin (2005)*, mentioned in Jagt et al.

The crabs from Kazakhstan all are of a different color and the concretion seems different. The box this one came in also had one that is definitely from Kazakhstan. I didn't think this one was but was labeled as Kazakhstan. For now I will go with Indonesia unless someone wants to dispute that locality. Thanks to all for the help. BTW- the concretion is 3 inches across. Sorry I forgot to put something in for size. Joe Link to comment Share on other sites More sharing options...
