Ptychodus shark tooth fragment?

[P het]

I need an expert's eye on this one . Looks like a fragment of an ptychodus shark tooth embedded in this sandstone.  I didn't knew what I have until I posted it on a fossil group on Facebook and some experts told me that it is an ptychodus shark tooth fragment.  It was found on beach at the gulf of kutch(65-2mya) late cretaceous-tertiary.  I founded that this shark lived during the late cretaceous period and the sediments from where it was found dated the same age.

Well 65-62 mya is after the KT extinction which is quite a ways after ptychodus is thought to have gone extinct. I think the youngest known ptychodus are from the early campanian. So if this was ptychodus, then that would mean they survived through the rest of the campanian, then the maastrichtian, and lastly got past the KT boundary. All this to say it's an unlikely ID. Maybe it's possible it was a reworked tooth that came from older strata and later got preserved in the formation you hunted in. The first pic kinda resembles ptychodus, but I can't tell if there's enamel present. The later pics don't look like ptychodus I can confidently say, though I'm not sure exactly what it is otherwise. Hopefully we get some more opinions. Nice to see some Indian fossils which are rare here. Happy hunting!

Actually the state in which I live has ample amounts  of dinosaur and cretaceous fossils (gujrat )  and  has worlds 3rd or 4th largest  dinosaur hatchery  but the problem is that people of here are not even exposed to very primary level of paleontology .

It's very difficult to tell with such fragments whether or not it's actually a clamshell or a Ptychodus crusher tooth. I am with @EPIKLULSXDDDDDon this one. The estimated rock age is too young for Ptychodus on first two pics. I think that the fragment is too small to be diagnostic.

 

If you had the crown to root transition area, then maybe it could be diagnosed. At this point, it could easily be a damaged bivalve fragment.

 

The second possible fossil pics are not a pattern seen on Ptychodus crowns. This could just as easily be a rounded mineral or rock fragment with striations.
