Ramo Posted May 6, 2009 Share Posted May 6, 2009 The article makes it seem super rare. I don't think it's that rare. For one species to mourn the death of another is a new thing under the sun. -Aldo Leopold Link to comment Share on other sites More sharing options...
RJB Posted May 6, 2009 Share Posted May 6, 2009 Im not even a sharktooth guy and I cant see how that can be rare? I think it would be rare if the great white sharks ate carrots and lettuce. Hmmmmm? Can one wonder...... RB Link to comment Share on other sites More sharing options...
Ramo Posted May 6, 2009 Share Posted May 6, 2009 A great white shark tooth lodged in a fossil carrot. Now that would be news!!! (That was funny RJB) For one species to mourn the death of another is a new thing under the sun. -Aldo Leopold Link to comment Share on other sites More sharing options...
fossilselachian Posted May 7, 2009 Author Share Posted May 7, 2009 The article makes it seem super rare. I don't think it's that rare. It certainly is not a "first" as indicated. I don't recall the shark species but there is an example on display in the Smithsonian and I seem to recall a similar event re a Cretoxyrhina tooth from Kansas.

mommabetts Posted May 7, 2009 Share Posted May 7, 2009 I would think that it wouldn't be that rare, but the carrot would!!!!!!!! Link to comment Share on other sites More sharing options...
Shamalama Posted May 7, 2009 Share Posted May 7, 2009 My question is are the teeth in bones the result of predation or scavenging? -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
Nicholas Posted May 7, 2009 Share Posted May 7, 2009 My question is are the teeth in bones the result of predation or scavenging? Good question, can it be tested? I'm very unaware of sharks and their behavior. Link to comment Share on other sites More sharing options...
Guest N.AL.hunter Posted May 7, 2009 Share Posted May 7, 2009 My question is are the teeth in bones the result of predation or scavenging? I think it is the result of the shark biting the whale bone Link to comment Share on other sites More sharing options...
Boesse Posted May 7, 2009 Share Posted May 7, 2009 The authors state that since most of the time when great whites feed on whales, it is an act of scavenging, and that they rarely attack whales. So, because of this, they say it is more parsimoniously interpreted as scavenging rather than predation (which is fairly sober compared to most other papers on this phenomenon). Shark tooth marks on bone certainly are 'common', and there are dozens of records of this in the literature. However, where the tooth is actually lodged in the bone, as far as the literature goes, is less common. I see people selling obviously faked pieces where a complete, pristine 3" GW tooth is lodged deep into a complete whale vertebra - but into the articular surface.
