ID french sea urchin

[Coco]

Hi,

 

I propose to the identification a fossil of a friend. This little sea urchin comes from the Black Cows, a famous site in the north of France. The age would be between Callovian and Oxfordian, or even more extensive.

 

It is really pentagonal in shape, with a relatively flat profile, and it has two rows of interambular tubercles.

It measures 12 mm in diameter and 7 mm high.

 

 

 

 

 

 

 

 

 

 

 

Thanks for your help

Hello,

 

For me it looks like Milnia sp., but you must have already considered that hypothesis and come to the conclusion that it is not.
