Gatorman Posted December 27, 2007 Share Posted December 27, 2007 Here's a tooth I found in Three Lakes Creek in Gainesville Miocene deposits, I think its a porpoise tooth but I'm not positive. Can anyone tell me for sure? Link to comment Share on other sites More sharing options...
Harry Pristis Posted December 28, 2007 Share Posted December 28, 2007 Here's a tooth I found in Three Lakes Creek in Gainesville Miocene deposits, I think its a porpoise tooth but I'm not positive. Can anyone tell me for sure? Anson, this image is out of focus like the other, the "sawfish rostral tooth." Whale teeth have "crinkley" enamel on their teeth. The dentin root tends to delaminate, layer by layer like an onion. There are some small toothed whales which have curved teeth like yours. -------Harry Pristis 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...
Gatorman Posted December 28, 2007 Author Share Posted December 28, 2007 Do you think booth these teeth are from the same animal? They were both found in the same area. Link to comment Share on other sites More sharing options...
Harry Pristis Posted December 29, 2007 Share Posted December 29, 2007 Do you think booth these teeth are from the same animal? They were both found in the same area. Even if they were from the same species, it is improbable they are from the same individual, Anson. If you are asking if they are from the same species, they don't resemble one another to my eye. There is a handful of species of these little whales in the Miocene. I've always prized these little teeth; they are hard to find. ---------Harry Pristis 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...
Boesse Posted January 28, 2008 Share Posted January 28, 2008 Anson, There are a myriad of different types of toothed whales in the Miocene, and if it is very small (only 3-4mm), then it could be from a Pontoporiid (river dolphin), which are common in late Miocene and early Pliocene rock units on the east coast. River dolphins have really recurved crowns like that, usually not seen in Delphinids. If its more like middle Miocene, then its possibly Pontoporiid, but more likely from a kentriodontid (proto-dolphin/porpoise). Bobby Link to comment Share on other sites More sharing options...
Gatorman Posted January 28, 2008 Author Share Posted January 28, 2008 Thanks I'll do some research on these. Link to comment Share on other sites More sharing options...
