I was given this around Christmas. It had a gray "dusty" coating. Upon cleaning/prepping it now looks like this. 003.JPG.bc8c7e1f6d372dd20ffe3d6a30f37437.JPG

 

Here's what makes me question it's authenticity...notice the gray matter down the middle and at the tip. Your thoughts?

Definitely not a shrimp. Looks like some kind of bivalve, maybe oyster?

Not sure on the specific name, but commonly known as a "zipper oyster".

I think this is Rastellum sp. the zigzag oyster . 

I think they come from Madagascar, not Morocco. 

It's a nice fossil.:)

I thought that's what they called a 'denture clam'! Lots of common names for it, I guess.

Bubbles would usually be a red flag for fakes, but it otherwise looks real to me - not unusual for any fossil mollusk to be filled with natural matrix - and I'm not sure why anyone would fake this relatively easy-to-get taxon (though I don't have one yet!)

Hi nice specimen l also think it is a shell half of Rastellum and from Madagascar as Adam said. Not shore about the pockmark at the end of the shell are but it is not really the type of fossil that is faked. I think it a nice fossil.

I am surprised! I only know Ordivician marine life, and some Devonian.

 

Thanks everyone
