Hey everyone!
I recently acquired this oyster from Tulear province, Madagascar. The seller has listed it as Rastellum carinatum, but doing any research online, I’ve only found other sellers selling similar fossils.
I did come across a Wikipedia article for Agerostrea sp. It appears to be the same shell, and it lists it as occurring in rocks that are Maastrichtian age from Madagascar.
Are these the same species just under different names or are they separate? If so, what genus does my specimen belong too?
Any response would be greatly appreciated from you guys, we’ll see how challenging this might be to figure out.
Thanks again
