Are the serrations on the lateral teeth of Spisula, a diagnostic character for the genus?
Hi Ranjeev Epa,
it does not seem so. Check WORMS and the links in there for original descriptions: http://www.marinespecies.org/aphia.php?p=taxdetails&id=138159
Dear Dr. Nauen,
Thanks very much. I have seen many guides which states that it was diagnostic. I was looking at some Pliocene fossils which does not preserve these striations that well.
Thanks again
Best,
Ranjeev
