Harry Pristis Posted September 9, 2009 Share Posted September 9, 2009 What sort of vertebra is this one from the Mio-Pliocene of Hardee County, Florida? It's almost certainly from a fish. I have a hunch what it is, but haven't been able to confirm its identity to the degree of confidence that I can put it in my drawer. Opinions welcome, but it you KNOW what it's from, give us your confirmatory source. http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
RichW9090 Posted September 11, 2009 Share Posted September 11, 2009 Harry, my first guess would be an amiid, given the ventral-dorsal flattening. Rich The plural of "anecdote" is not "evidence". Link to comment Share on other sites More sharing options...
Harry Pristis Posted September 12, 2009 Author Share Posted September 12, 2009 Harry, my first guess would be an amiid, given the ventral-dorsal flattening. Rich Thanks, Rich. I hadn't considered an amiid. Amia calva is known as a fossil from Florida from Miocene to Pleistocene. It is a freshwater fish, however, and this vertebra is almost certainly from a marine fish based on associated fossils (lots of shark teeth). I couldn't access a cross-sectional view of an amiid vertebra on the www. The line drawing of a single Amia vertebra in Hulbert's book does not indicate dorso-ventral compression. A dogfish large enough to produce this vertebra would be formidable indeed! http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
