KCMOfossil Posted April 29, 2017 Share Posted April 29, 2017 This tooth is from the Winterset Limestone Member, Kansas City Group, of the Pennsylvanian Subsystem. Any help with an ID will be appreciated. Russ Link to comment Share on other sites More sharing options...
westcoast Posted April 29, 2017 Share Posted April 29, 2017 'Cladodid' type of shark tooth. More precise ID may be difficult. What shark teeth are recorded from that member or Group? Link to comment Share on other sites More sharing options...
BobWill Posted April 29, 2017 Share Posted April 29, 2017 I agree. If I found that in north Texas it would likely be Glikmanius (= Cladodus) occidentalis for making comparisons. Find a fauna list for your site or formation to see what species yours is. Link to comment Share on other sites More sharing options...
KCMOfossil Posted April 29, 2017 Author Share Posted April 29, 2017 Thanks for the IDs. I checked a description of the fauna and it looks like you are right. Cladodus are found in this area and the photos I see online seem to match my tooth well. Russ Link to comment Share on other sites More sharing options...

TNCollector Posted April 30, 2017 Share Posted April 30, 2017 Yeah Cladodus. It's not worth putting a species name to it, even the genera names are all mixed up on these teeth. The same teeth in different publications are simultaneously labeled as Cladodus, Glikmanius, and Symmorium. I have my own opinions on how to distinguish those 3 genera, but that's a topic for another time. Link to comment Share on other sites More sharing options...

KCMOfossil Posted April 30, 2017 Author Share Posted April 30, 2017 I looked in Richard J. Gentile’s book, Rocks and Fossils of the Central United State with Special Emphasis on the Greater Kansas City Area, and on p. 88 he mentions shark teeth being found in the Pennsylvanian age rocks here (near Kansas City) and he has a drawing of a cladodont-type tooth which he labels as “Cladodus” without specifying the species. I was quite pleased to find this tooth. I have only found two shark teeth in the three years or so that I have been collecting here. The ones I have found have been embedded in rocks I have split, and the teeth are so fragile that it seems unlikely that they would survive long exposed to the elements.

Bullsnake Posted May 6, 2017 Share Posted May 6, 2017 That's a nice one! Congratulations! I have only found crowns with no basal plate, and basal plates with the crown broken off. Most of my cladodont finds are from the Hickory Creek sh. Steve Link to comment Share on other sites More sharing options...
