Recommended Posts

Hi, I have found a place .. there is a Czech Cretaceous basin and there is an abundant fossil bivalve Innoceramus - But several species (  Inoceramus lamarcki (PARKINSON), Inoceramus cuvieri SOWERBY, Inoceramus inaequivalvis (GÜMBEL) ) and I do not know what key to follow in their determination. Please advise, or I would like to ask what kind of photo is it?

Considering that it might be an internal mold or a very weathered specimen of Inoceramus, I think it will be hard to narrow it down to species level. :unsure:

Vzhledem k tomu, že by to mohla být vnitřní plíseň nebo velmi zvětralý exemplář Inoceramus, myslím, že bude těžké to zúžit na úroveň druhu. :nejistý:

Even if you didn't please me. Thank you for the birth ... I have better pictures, but a different sample
