Past Hunter Posted April 22, 2019 Share Posted April 22, 2019 I’m in need of some help on some old finds from Aurora. I thought shark nose, crocodile, whale tooth, what do you think. 2 "If you choose not to decide. You still have made a choice." - Rush Link to comment Share on other sites More sharing options...
Shellseeker Posted April 22, 2019 Share Posted April 22, 2019 1) Geologic concretion, 2) Crocodile Osteoderm 3) Looks like a 2 inch tooth tip. Doubt if it is whale. Might be Croc. More photos would help. 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

Carl Posted April 22, 2019 Share Posted April 22, 2019 I definitely see the shark nose and the croc osteoderm. The last sure looks like a tooth but I can't ID from these photos. Link to comment Share on other sites More sharing options...

Didn't know what they were at first either but the great Becky Hyne identified them for me. Then I saw I also saw photos of them in the Smithsonian Lee Creek Vol. III book (which I highly recommend if you don't already possess it).

BeckyHyne Posted September 5, 2020 Share Posted September 5, 2020 It's really me. Becky Hyne here...I'm still kicking. Not doing a lot of fossil hunting, but dreaming and reminiscing. I'm currently in Red Level Alabama and looking forward to checking out fossil locations around here if I can. Link to comment Share on other sites More sharing options...

So, all that remains of sharks as they fossilise are their teeth, vertebrae and nose (at least in some species)? Is the nose made of cartiliginous bone in live as well? As to the identity of the remaining fossils, I'm afraid I'm not of much help there, other than being able to confirm the crocodile scute / osteoderm the others have also pointed out already... For me, the additional photographs of the tooth don't make things much clearer, though it doesn't look like a crocodile tooth to me - based on the shape of the cross-section. In fact, the cross-section seems too irregular to me to match a tooth, even if the outline of the fossil is very reminiscent seen from other perspectives. I mainly go in for mesozoic reptiles, but based on the white outer surface, could this not be some kind of shell, may be something like a rudist (though those were obviously long extinct by then)?

Coco Posted September 6, 2020 Share Posted September 6, 2020 Hi, The skull and nose of a shark are also made of cartilage, like all hard parts of their body.

Shark cartilage can also be found, and is a relatively common find at the Lee Creek Mine (now closed). I have a box full. They always seem to be small and fragmentary, however, no larger than a thumbnail or so. Of the ~100 pieces that I have collected from there, only one is identifiable as to location--under the eye. I have seen isolated finds of cartilage from various locations, but I cannot believe that only LC has them in any abundance. I suspect most people don't know what it is, so they either don't pick it up, or they do and it's in the "unidentified" box that we all have, haha 1 'Those who cannot remember the past are condemned to repeat it.'
