Crocodile Egg or Sea Urchin?

During a trip to Egypt I found this potential fossil near the city of Aswan between the banks of the Nile River and Sahara Desert. I had thought it might have been a meteor and the sand fused around the meteor due to the Intense heat. But, I tested it with a magnet but there was absolutely no attraction. Therefore, I thought it might be a fossil given that I read about many fossils being discovered in the Sahara and the composition does appear to be any rock or stone that I've ever encountered. I assumed crocodile due to the spiky and bumpy texture, along with the historic prevalence of crocodiles in that region.

 

What do you think this is?

 

Thanks!

A very cool and collectible concretion.

Fossil hunting is easy -- they don't run away when you shoot at them!

I agree with the others. It looks like a concretion, probably with a pyrite or marcasite core.
