I'm quite used to finding small fish vertebra from these small sized fish coprolites @GeschWhat from the Oxford Clay of Peterborough. But this one below has more of a shark vertebra appearance, or are there different variations of fish vertebrae. All vertebrae measuring between 2 and 3 millimetres. This one below is also a fish vertebra.
Hi there I found this vertebra on the beach here at Walton on the Naze, Essex, UK. Unusually it was found on the sandy beach near the pier rather than the usual spot near the cliffs. Anyway, from the little I know is it right to assume that shark vertebrae have regular bony connections in the profile, Ray vertebrae tend to be smooth in profile and bony fish have irregular profiles. Is this generally true or am I way off the mark? Given that, is this a bony fish vertebra rather than shark, and if so is there any way to pin it further down to a given species?
From the album: BONESFossil fish vertebra from the well of a gun-pit in a phosphate mine, Polk County, Florida. This vertebra exhibits hyperostosis, an overgrowth of bone, found mostly on the vertebrae and internal spines of some fish. The perforations alongside the centrum may represent what's left of the neural and haemal canals of the vertebra.
