Fish teeth are cool. Must be for mashing.

Bait was small clam clusters, barnacles or fiddler crabs. Sneaky fish, one tiny nibble and you gotta set the hook hard to get the hook in his bony jaw. Never saw such blunt teeth on a fish, but makes perfect sense.

From the little I've read about this fish, the whole inside of the mouth was lined with these crushing teeth. Thus the 5 smaller teeth in this specimen.
Did you notice the vertebra in the pic ? On the reverse side there's what appears to be part of a rib bone.

On the reverse side there's what appears to be part of a rib bone. I did see that vertebrae. I need to look up that species of fish and see if they still exist. The Gummy Shark has similar teeth. Stingrays have flat anvil teeth but w/slight serrations. Pycodnus extinct, but it was a ray like fish.(Wiki)

Here ya go James. I'll save you the trouble.
Pycnodonts, are an extinct order of holostean fishes. These fishes had deep, nearly circular bodies, body armor of jointed rodlike scales, and mouths containing many pebblelike, irregularly arranged crushing teeth. Although it has been commonly thought that the pebblelike teeth were adapted for crushing corals (Romer, 1966), it seems more likely that they were adapted for crushing thin-shelled animals (Slaughter and Thurmond, 1974).

Very nice fossils, Don! Enjoyed reading the posts on the fish teeth. I normally don't trust fossils from Morocco, but this one is from a trusted seller who personally inspects everything he buys for resale. I read a bit about the fake Moroccan fossils while researching the Dicranurus trilobite. Don, do you collect trilobites, too?

I bought it knowing full well that it was partially fake. I wanted a teaching aid to show to others. Those crazy looking little water bugs are some of my favorite fossils.

Nope. Good specimens are very expensive, and most are heavily repaired or made up with parts from several specimens.

In my opinion,their fossils are "plain Jane" with no character or class!!! Plus the big factor,they flooded the market with their junk and slid our prices (USA) down the toilet!

This is just one cool water bug. Probably a fake? Can you discern if it's been repaired with glue with a UV light similarly to repaired mineral specimens?

Jan, if that's a Moroccan specimen there's a better than good chance that at least the spines are made up of colored epoxy. Often the repairs will show up under UV. Also, if you look carefully under magnification, you'll see air bubbles in the epoxy. China's fossils are also highly suspect.
Many real museum specimens are also extensively repaired. Museums do it to show their patrons what the critter would have looked like in life.
