Shellseeker Posted June 7, 2019 Share Posted June 7, 2019 I was introducing my great_nephew Jake to the Peace River, he foscused in "small, tiny" fossils and found some good stuff... One was shark teeth, and the other a claw. looks birdlike to me so calling on @Auspex to help ID or just speculate. The 6mm shark teeth: The 7 mm claw: All suggestions and comments appreciated. 3 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted June 7, 2019 Share Posted June 7, 2019 Those shark's teeth are wonderful! And i would say bird too, but can't get any nearer than that. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Auspex Posted June 7, 2019 Share Posted June 7, 2019 It's kind of heron-like in morphology, but very small. I lack access to a comparative collection, but (right or wrong) maybe this will get you started.

Racheld1 Posted June 7, 2019 Share Posted June 7, 2019 Nurse shark teeth? Very cool! Don't have any in my collection sadly. Link to comment Share on other sites More sharing options...
Coco Posted June 7, 2019 Share Posted June 7, 2019 Perhaps Ginglymostoma or Nebrius ?

PODIGGER Posted June 7, 2019 Share Posted June 7, 2019 Great finds and wonderful to get a youngster involved in something that gives him an historical perspective. Link to comment Share on other sites More sharing options...

But I think the only "fossil" nurse shark from Florida recognized is Ginglymostoma delfortriei, as identified by Richard Hulbert's book: These 2 that Jake found are approximately 6 mm = .236 inches. This is really difficult using a .25 inch sieve.. With any jiggle these teeth fall thru the sieve. 7 hours ago, Auspex said: It's kind of heron-like in morphology, but very small.

Seems very similar in shape. I will continue looking .. There are some SMALL herons like the little green. 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...
Auspex Posted June 7, 2019 Share Posted June 7, 2019 What is needed are terminal phalanx pictures. All the ones for "talon" show the sheath, which is too generalized a structure for ID beyond family (generally). Bones tell the tale.

I did not take a photo from that angle, Jake & family left today heading north. I will send him an email. We'll see.

Auspex Posted June 8, 2019 Share Posted June 8, 2019 Sorry to be confusing, @Shellseeker, the bone in question is a 'terminal phalanx'. I meant that images for ID reference should be of the underlying bone, not of the keratin 'claw' sheath.
