Unknown bivalves
Hello again!!

Here are some bivalves. I only know the location of the first one, so any suggestions of possible/ approximate location would be very helpful. I have taken photos from various angles, so that you can see the hinge and general structure. Thank you for all your help,
Best wishes,

Number 1: Great Britain, 1980's, self-collected in rock pools; 34mm:

Could the first one be Tapes (Venerupis) aurea?  It's a pretty variable species, and found in that locale.  Does it have a yellow interior?
The last one looks like Meretrix lusoria. (This looks like it has a thin periostracum on it. Is that correct?)

#2 has an Anomalocardia shape.
Perhaps Anomalocardia brasiliana (Carribean province).

Yes, Paul, the first one deffinetely has yellow colouring inside, so I agree with your identification: Tapes (venerupis) aurea. However, the brown one has no periostratum, it is actually that chocolate brown colour, and I have no idea what it could be. Do you have any other suggestions? I don't think it is Meretrix lusoria because, as I say, it hasn't got a periostratum. Thanks for your help.

Hello Pierre, I think it is too wide to be Anomalocardia. I think maybe the location is oriental (China, Japan), but I can't be sure. These shells belong to part collections I have been given over the years. Do you have any other suggestions? Thanks for your help.

Hi Emma, Meretrix meretrix can come in a solid brown colour, I have examples myself.
