fossilnut Posted July 8, 2018 Share Posted July 8, 2018 From my attempts to get information about the types of sharks matched to centra has not been successful. I understand that it is complicated and one reference said there were 14 specifics to ID but it did not provide those criteria. I want to display these shark centra for a "Shark Week" display for the Natural History society of Maryland. Any information that TFF can provide me would be helpful. There are 3 differing pattern on the sides of the centra as shown in the attached pictures. Can we associate any of these types with the megalodon shark? Thanks for your help.

fossilnut Posted July 9, 2018 Author Share Posted July 9, 2018 @sixgill peteSince I did not receive any responses to this post, I am reaching out to you since you have helped me in the past for any help you can provide or suggest someone else. I have become very confused as to what type of shark correlates to the different centra. Thanks for any consideration you can give to this request I would really appreciate it. The last picture is the most common of the centra that I have found. If I have done something wrong in my posting please let me know so I can do better.

ynot Posted July 9, 2018 Share Posted July 9, 2018 It is My understanding that there is not enough associated pieces (teeth with verts) to be able to put a genus on most shark verts. I know that some are oval and are considered to be ray or angel shark. Maybe @MarcoSr can shed some light on this. Darwin said: " Man sprang from monkeys."

fossilnut Posted July 9, 2018 Author Share Posted July 9, 2018 (edited) Thanks for your encouragement and passing this on. Maybe there is enough info for family of sharks. I would be especially interested if a type of centra could be associated with the family of megalodon because as part of shark fest at NHSM they are unveiling a reproduction of a meg's jaws with real meg teeth. Size of the centra would play a role in id (I think) but still the edge pattern is telling I would expect. One other example I would be interested in id'ing is the tiger shark Galeocerdo. I read that there is a pattern of pores that look as if machined stitched. They have an interesting story to tell about their feeding on sea turtles and then emitting their stomachs to discard the shells. I think this would interest both kids-disgusting and some adults. I Appreciate any help from TFF Edited July 9, 2018 by fossilnut added a sentance about pore pattern Link to comment Share on other sites More sharing options...

A previous TFF post of mine at the link below might help you a little: http://www.thefossilforum.com/index.php?/topic/71769-identifying-sharkraybony-fish-vertebrae/&tab=comments#comment-755584 Your last two vertebrae are definitely not meg. I don't think your first one is meg either. I think the damage to it may make it look like it might be from a meg. Look at Otodus vertebrae on e-bay (There are usually lots of Otodus vertebrae and usually no meg vertebrae) for an idea of what a meg vertebra looks like. Below is a picture of an Otodus vertebra from ebay: Marco Sr. 2 "Any day that you can fossil hunt is a great day."

fossilnut Posted July 10, 2018 Author Share Posted July 10, 2018 @DrMudd Back in 2/17 in response to MarcoSr post about identifying shark centra you indicated you had a number of papers. I hope I am not being impolite in requesting that you post papers or links or info on such papers. A number of members on Tff would greatly appreciate it. Hope I am not out of line with this request.
