Hi all,
I have this shell fossil that I found and was wondering if anyone could name it. I've read some literature to try find the answer but as I am an amateur I need some help. It was found in Motunau in the South Island of New Zealand where the fossil age of this location is said to be about 2.5 MYA, Nukumaruan stage of the Pleistocene. My best guess was that it may be a Cyclomactra Ovata. However the literature says that they are 60-70mm wide, where mine is more 40 mm.
Any help would be greatly appreciated. Thanks in advance for you help.
