Details of two Rhinopteraspid Fish's Ventral Preoral Regions
Biotalker posted a topic in General Fossil Discussion
I thought I would share this recent fossil purchase. I was fortunate to obtain this fossil from the lower Devonian in the southwestern region (Podolia) of Ukraine. Two ventral snout regions of type of heterostracan (jawless) fish called rhinopteraspid are exposed. The bone detail is simply remarkable. There is “tiling” of the underside of the long (rhino) snouts with dentine and/or aspidine (acellular enamel-like substance) in parallel lines arrays with a more uniform bone matrix underneath. The pre-oral-plate is angled in toward the mouth and displays many external textures of bone that presumably aided the fish’s feeding. I didn't expect to see this level of detail.- 4 replies

Dear Fellow Fossil Fanatics, I just had a great day at Big Brook, found some shark teeth but also 3 specimens that I am not sure at all what to make of. Any insights would be awesome! Best, Huttner

2 unidentified mosasaur species' anterior end of premaxillary bones. One with teeth broken off just beyond the skull, and the other has 2 remaining teeth, with the rest broken off at the level of the skull. the larger fossil was found in the phosphate mines of Khouribga, Morocco. ive since lost the information for the smaller fossil, sadly.
