PSchleis Posted January 26, 2019 Share Posted January 26, 2019 Sorting my sharks' teeth. Not 100 percent sure about some of these. There are just enough differences to throw me. I used a flash because it seemed the best way to highlight the details. First picture front, second picture back. Thank you! Link to comment Share on other sites More sharing options...
ynot Posted January 26, 2019 Share Posted January 26, 2019 Two largest are squalicorax (crow shark). Not sure about the smallest one. The others look like Galeocerdo sp (.tiger shark) Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

caldigger Posted January 26, 2019 Share Posted January 26, 2019 I'm thinking the little guy is a Squali also. The one that I am not sure about is that one behind the smallest tooth. It has the general shape of the Squalicorax, but with a sharper tip and doesn't seem to have the offset shape of the Tigers. 2 Link to comment Share on other sites More sharing options...
sixgill pete Posted January 26, 2019 Share Posted January 26, 2019 It would help for getting good positive ID's if you would take individual pics of both sides of the teeth. Well let and in focus. Also using a U.S. coin for scale is a disservice to our international members, many of whom have no idea how big a quarter is. Please use a small rule or give us length and width, preferably in millimeters. Reading some of the pinned threads about how to get your item ID'd can be very helpful. While I agree the 2 largest and the smallest teeth are Squalicorax sp. Individual pics could help ID them to species level. There is more than 1 species of Crow shark in the Cretaceous PeeDee Fm. Found at Myrtle Beach. The three in the upper right are Galeocerdo sp. (tiger shark). The other tooth i am not sure about and would definately like to see more pics of. 1 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...
The Jersey Devil Posted January 26, 2019 Share Posted January 26, 2019 The two crows are Squalicorax pristodontus. “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...

I agree the 2 large ones most likely are S. pristodontus. But the smallest tooth is also a Squalicorax.

I haven’t seen one with a nutrient groove before. “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...
non-remanié Posted January 26, 2019 Share Posted January 26, 2019 Just the 2 big ones are Squalicorax to my eyes. ---Wie Wasser schleift den Stein, wir steigen und fallen--- Link to comment Share on other sites More sharing options...
