Other Algerian pelecypods

[fifbrindacier]

Hi everybody, here are others fossils from Algeria that were given to me. They mostly are ypresian pelecypods imprints. Their finder wrote ctenodonte, i think the one on the left of the first photo and on the top on the following is one, i am right ? They all three are about 3 cm of width (a little more than 1 inch).

I took some of my photos without flash, like those two ones :

1)

 

2)

3) about 4 cm of width (less than two inches) :

Nice bivalves!

I can't help you much, but I think the last one could be a veneroid (Veneroida order).

I think you are right Hugo, thanks for your answer.

These appear to be Trigonia which would probably date to Cretaceous.

number 3 looks like this one...

or that one.

Trigonia seems to be a very good match.However, if I'm not wrong, they can also be found in Jurassic layers.

You are correct.  Here in my region of the world I collect them in Upper Cretaceous layers.  There is a single species still living in Australian waters but I would think that fifbrindacier's specimens are Mesozoic as opposed to Cenozoic.

The phosphates in that region are ypresian, but there is a cretacean ground nearby. The person that gave them to me said it came from what the french called a "escargotière". The "escargotières" are places were the ancestors of the Berbers had their encampements. They were called like this because of the numerous shells you can find there. As i don't know precisely were it is, it could be in the cretacean ground, or, maybe the men had brang them there.

Guguita said it was a Veneroida, your identification of Astarte confirm that. I thank you very much all of you for your help.
