rplopes Posted February 20, 2009 Share Posted February 20, 2009 Hi, I'm a paleontologist from southern Brazil, and my research is focused on Pleistocene Mammals of the coastal area. In the paleontological collection of my institution we have the two specimens on the attached picture, found on the beach. My first guess was that they were beaks from puffer fishes (Family Diodontidae), but a colleague said that the denticles indicate that they were from parrot fishes. Does anyone know more about this group or have seen similar fossils? Thanks! Link to comment Share on other sites More sharing options...

Pool Man Posted February 21, 2009 Share Posted February 21, 2009 Hi. Welcome to the Forum! I call these puffer fish(Diodontidae)plates.I've also seen them refered to as porcupine fish. Here are some examples from the Caloosahatchee shell beds in North Port, Florida. I seem to recall that the more rounded ones are the lowers and the more pointed ones are the uppers.

rplopes Posted February 21, 2009 Author Share Posted February 21, 2009 It was difficult to identify these fossils. I've searched the FAO catalog, but it shows no details on the morphology. Can anyone say if they are upper or lower beaks? They were found several kilometers from each other, and not during the same field trip, so it's very impprobable that could be from the same animal. If they are fossils of Chilomycterus, then it's probably C. geometricus, relatively common in the Brazilian coast. Thanks for all the comments...this forum is of gret value for us paleontologists.
