Unknown bivalves - Emma - 09-07-2011 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, Emma. Number 1: Great Britain, 1980's, self-collected in rock pools; 34mm: Number 2: one half bivalve, 50.8mm: Number 3: 38mm: Re: Unknown bivalves - paul monfils - 09-09-2011 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?) Re: Unknown bivalves - conchylinet - 09-09-2011 #2 has an Anomalocardia shape. Perhaps Anomalocardia brasiliana (Carribean province). Pierre Re: Unknown bivalves - Emma - 09-11-2011 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. Re: Unknown bivalves - dave r - 09-12-2011 Hi Emma, Meretrix meretrix can come in a solid brown colour, I have examples myself. Dave Re: Unknown bivalves - Emma - 09-12-2011 Thanks Dave!! Re: Unknown bivalves - poseidon - 12-01-2011 the correct name actually is paphia aurea  Re: Unknown bivalves - Emma - 12-06-2011 Ok, thanks!, I'll modify my records.
