Guest Nicholas Posted April 27, 2008 Share Posted April 27, 2008 I think it could possibly be a shark bite, but the scratches seem too numerous close together. I haven't seen any other "bite" fossils like it. Link to comment Share on other sites More sharing options...
PrehistoricFlorida Posted April 27, 2008 Share Posted April 27, 2008 More resembles Native American cuts than shark bites to me. www.PrehistoricFlorida.com Link to comment Share on other sites More sharing options...
Auspex Posted April 27, 2008 Share Posted April 27, 2008 I've seen "serration scrapes" that were similar, but they were perfectly parallel, as would be the case from a serrated tooth. These marks are all headed in the same general direction, but some of them seem to converge. Under good magnification, are they also variable in depth?

worthy 55 Posted April 27, 2008 Author Share Posted April 27, 2008 Yes they are all about the same depth. The bone is the lower end of a Dugong rib. It's my bone!!! Link to comment Share on other sites More sharing options...
gatorjames85 Posted April 27, 2008 Share Posted April 27, 2008 I think Auriculatus is right. They look like cut marks. Link to comment Share on other sites More sharing options...

worthy 55 Posted April 28, 2008 Author Share Posted April 28, 2008 I guess it would have to be a caveman seeing that this rib just came out of a phosphate mine. Don't ya hate that when that happen's It's my bone!!! Link to comment Share on other sites More sharing options...
Harry Pristis Posted April 28, 2008 Share Posted April 28, 2008 Well what do you all think, shark bite or not? I think they are likely to be shark bite marks, Worthy. They don't all have to be from the same shark at the same moment. Imagine several sharks scavenging a carcass, thrashing and biting in competition to strip flesh from bone. Or, imagine one shark with a good bite on a rib-end, thrashing, multiple teeth sawing away to separate a bite it could swallow. Grim, but that's how sharks do it. 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...
gatorjames85 Posted April 28, 2008 Share Posted April 28, 2008 Must have been a shark if it's that old. Not much else (besides man) would gouge out a dugong rib. Link to comment Share on other sites More sharing options...
