Micro fish tooth Cretaceous

Any ideas on this one?

 

Found at the bottom of the Eagle Ford/ top of Woodbine.  It is 4mm long and 1.5mm wide.  Found on a slab with lots of fish parts.

Ok someone has seen one of these right?  Anyone think it’s not a tooth? Totally open to that.  It would put it to bed quicker. :)

it's a fish tooth, but that's as far as I'll go.

The problem is there are many species of fish that have the same shape of teeth.

Not up on my fish teeth but from the shape I would assume it is some type of crushing tooth so possibly from a fish that ate crustaceans, though not as robust as a fish that targeted molluscs or as pointed as a predatory fish eater. Also it is a rooted tooth so that also eliminates some fish family's. 

Someone here may still know to what fish it comes from.

I did get an ID offline from someone who definitely knows their stuff.  Reptile tooth, most likely Coniasaurus.

 

Unrelated to the ID, I started searching for pics and Lance who has the North Texas Fossils page has some Coniasaurus pics there that also come from Eagle Ford.  It’s the second to last section near the bottom of the page.
