tracer Posted November 29, 2009 Share Posted November 29, 2009 a lot of the time drum pharyngeal grinding plates lose the teeth before you find the plates, but those fish always seem to have more teeth growing up from below that are buried in the plate beneath the surface. i broke up a couple of plates and took the teeth out to show you, along with a picture of a plate as typically found in my area.

bigjohn835 Posted November 29, 2009 Share Posted November 29, 2009 It's hard to believe that they are teeth. They are really cool looking. Are they actually animal teeth? With rocks in my head, and fossils in my heart.... Link to comment Share on other sites More sharing options...
Auspex Posted November 29, 2009 Share Posted November 29, 2009 It's hard to believe that they are teeth. They are really cool looking. Are they actually animal teeth? Yup, Drumfish. I imagine them as being pretty grumpy, grinding their teeth all the time...

tracer Posted November 29, 2009 Author Share Posted November 29, 2009 It's hard to believe that they are teeth. They are really cool looking. Are they actually animal teeth? yes - from big fish that have them in their throats to help crunch up the hard-shelled stuff they eat. Link to comment Share on other sites More sharing options...

tracer Posted November 29, 2009 Author Share Posted November 29, 2009 Tracer, interesting pictures...so what age stuff is this? what formation? Regards, Chris it is from the beaumont formation, which is a very dense clay. the beaumont is pleistocene in age, but the material could also probably be holocene reworked down into the upper part of the beaumont. stuff found along the coast seems to vary substantially in apparent age from its density, coloration, and relative state of preservation. lots of transgressive coastal erosion going on in some areas of louisiana and texas.

Roz Posted November 29, 2009 Share Posted November 29, 2009 yes - from big fish that have them in their throats to help crunch up the hard-shelled stuff they eat. That plate was in the throat then! Most cool. Glad you took them apart. It that is the original position, those small positioned next to larger must not be random. All designed for what they ate. Welcome to the forum!
