Kolya Posted March 28, 2020 Share Posted March 28, 2020 Hello! Help, please, with identification. I think that one of them is part of Heterodontus tooth. Scale in mm. Western Ukraine. Age unknown (Cretaceus-Neogene). Thanks in advance! 1 Link to comment Share on other sites More sharing options...

fossilsonwheels Posted March 29, 2020 Share Posted March 29, 2020 The second tooth is a Heterodontus lateral tooth. I am not sure about the other two. 1 Link to comment Share on other sites More sharing options...

sixgill pete Posted March 30, 2020 Share Posted March 30, 2020 Knowing the age of the sediments greatly increases the chances of identification. Otherwise we are guessing. Yes the one tooth is Heterodontus but that is th he Genus. It cannot be I.D.'d to species with out knowing the formation and age. 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...

There are deposits of Neogene (Miocene) but also some redeposits which coud be from Cretaceus or Paleogene... If possible to identify genus is would be very nice. And the most interesting tooth for me is the first one... Link to comment Share on other sites More sharing options...
