Miocene crab identification from Al Ain, United Arab Emirates

[MrBones]

Hello all,

My posts have become infrequent as I have moved back from the UAE to my home country. However, I still have a lot of specimens that I would like to id, like these crabs!

I found them in Al Ain, close to Jebel Hafeet. I think they come from either the Miocene, or Eocene, as the region produces a lot of nummulite fossils.

I think that all of these crabs are from the same species (mostly because of the two points present on either side of each of their carapaces.)

 

Here is the smallest out of the lot.

 

 

 

 

I was hoping to enter this next specimen to fossil of the month (one of the reasons I want an identification). I am still in the process of preparing it. It's about 4-5 cm wide.
