James Savage Posted February 3, 2023 Share Posted February 3, 2023 Hello everyone I went on a commercial dino dig tour Summer 2022 of the Hell Creek formation in the Butte County, South Dakota area and found lots of bones and spitter teeth and had a great time. These two were in my unknown/unidentifiable pile and I've recently done some cleaning/prep to them and was requesting some help with possible IDs. The first item (on the left in most of the images) looks like a broken rooted ceratopsian/triceratops tooth to me with ridges and enamel showing. The second item (on the right in most of the images) looks a little like a scute with a raised round/circular area in the center and a lot of what looks like scratch marks on the opposite surface. I'm a newbie to the Hell Creek and these guesses may be off. Let me know if you would like any additional angles or detail for help with the ID. Thanks a bunch for looking 1 Link to comment Share on other sites More sharing options...
Troodon Posted February 3, 2023 Share Posted February 3, 2023 Yes that does look like a Ceratopsian tooth with most of the crown missing just roots. Not sure on the other might be an Osteoderm, pretty worn Link to comment Share on other sites More sharing options...
jpc Posted February 3, 2023 Share Posted February 3, 2023 the other one looks like a water worn chunk of ceratopsian frill. 1 Link to comment Share on other sites More sharing options...

hadrosauridae Posted February 4, 2023 Share Posted February 4, 2023 (edited) Nice couple chunks of trike. First is a tooth with a great root, shame the crown is broken. The other looks like a well worn bit of trike frill. Was this your first time with Walter? Edited February 4, 2023 by hadrosauridae "There is no shortage of fossils.

James Savage Posted February 4, 2023 Author Share Posted February 4, 2023 Thanks so much for everyone viewing and replying to the thread. I appreciate everyone's expertise. This was my first trip with Walter and I've got 2 more separate trips booked with him this summer. I've been going through my findings from last year and looking forward to the summer. Thanks again 1 Link to comment Share on other sites More sharing options...
