Fossil sea urchin identification?

[Fossilia]

Dear friends,

This is my first fossil and I am new in this forum.

Someone please help me to identify this?

Thank you

It is an irregular sea urchin, similar to Hemiaster.  However there are many genera, and many many species, of such urchins that have been described.  If you can tell us where (at least approximately) you found it, we might be able to narrow down the age and geological formation, which would be useful to arrive at a more confident identification.

Dear Don,

Thank you for these informations. I found in the river, region of Khenchla, northeast of Algeria at 1500 m altitude.
