Tail? Leaf?

by Andree de Jong
(Spain, Almanzora Valley)

Next to my house is an old riverbed, I love to go looking for special stones/fossils and found this.
I tried to find anything that is looking a bit like that, but no.
So I would be very pleased if you could help me.

Rudist Bivalve
by: Michael

Difficult to be sure, but this might well be a piece of a Rudist bivalve - an offshoot of the Oyster family, which lived in the more southern climes during the latest Jurassic and Cretaceous Periods. They had one horn-shaped valve, like an ice-cream cone, and a small valve on the top. Rudists could form sea-floor colonies or even reefs, rather like corals, but they were unrelated, being molluscs.

I have also come up with nothing similar to your find.

I did find some reference to mollusk fossils in that area but this does not look like mollusk to me.
