Echinometra mathaei?

Hello, 

I recently picked up these fossil sea urchins. I think they're miocene in age. I'm not quite sure if these are different types of urchins, or if they are just in different stages of weathering. I put a modern "burrowing urchin" next to the largest one as a comparison. Found in Ruwais, Abu Dhabi, UAE (United Arab Emirates) on a beach with dredged materials on it.

Hi,

 

I just watched the same article!

Echinometra miocenica seems to be a fossil synonym for Echinometra mathaei.

Interesting! Do you think that all the urchins in the photos are the same species?

The one on the right is the best preserved. See if you have the same number of pore pairs on each other, it’ll probably be the only discriminant clue left on those fossils (4 pores pairs).
