Darbi Posted April 4, 2020 Share Posted April 4, 2020 I found this very interesting fossil yesterday and I do not know what it is. Found it in Ellsworth County by Kanopolis reservoir. It's from Kiowa formation/Kiowa Shale and age is Albian. Dimension is 5/16 inches wide and 3/8 inches long or about 8 mm wide and 9.5mm long. I have never seen anything like this before and I hope somebody else have an idea what it came from! 1 Link to comment Share on other sites More sharing options...
connorp Posted April 4, 2020 Share Posted April 4, 2020 Hm. Looks modern to me, but I have no idea what it is. Link to comment Share on other sites More sharing options...
Ludwigia Posted April 4, 2020 Share Posted April 4, 2020 Drumfish tooth maybe? 3 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted April 4, 2020 Share Posted April 4, 2020 It looks like a drop of pitch. Check if it melts with a hot nail or thick wire. Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
Darbi Posted April 5, 2020 Author Share Posted April 5, 2020 It cannot be modern or a drop of pitch because I literally yanked it out of the bluff. It was part of the underneath of capping shale that stuck out of the bluff. In other words, this black thing were inside the shale before I broke it free. I have thought it might have belonged to a fish... Link to comment Share on other sites More sharing options...

Correction: It didn't come from the bluff, it was on the beach as a weathered boulder which this piece came from and it came apart when I removed it. I was thinking of another matrix that I removed from the bluff. The matrix from beach containing this 'black drop' also contained small vertebrae of same color. This led me to thinking it's probably a fish. Link to comment Share on other sites More sharing options...
Darbi Posted April 5, 2020 Author Share Posted April 5, 2020 After digging around on the internet for a while, I think I found the answer! It's a tooth from Pycnodont fish: Coleodus sp., possibly Coleodus brownii. The round, stone-like teeth were used for crushing the shellfish and other hard-shelled preys. http://oceansofkansas.com/Pycnodont.html A picture of very similar tooth: 1 Link to comment Share on other sites More sharing options...

grandpa Posted April 5, 2020 Share Posted April 5, 2020 Great joy in solving the mystery and finding a look-alike photo to go with the solution. That is a special find. Job well-done. Kudos also to @Ludwigia and @Darktooth for recognizing what you had. Link to comment Share on other sites More sharing options...

The modern and pleistocene drum teeth looks very similar to the teeth of Coleodus sp. and the suggestions from both of you did help some in giving me the direction that pointed to the Coleodus sp. Thank you both for helping me. 1 Link to comment Share on other sites More sharing options...
