Slow Walker Posted August 12, 2022 Share Posted August 12, 2022 Find this laying on top of Pierre shale out cropping as if it was dropped by bird or came out of above matrix. I tried putting a tip of it into vinegar and did not fizle but it did degrade the bone and made it soft so it would kind of fall into powder pieces when scraped. I tried burning the tip of it but it did not burn might have been because it was wet from the vinegar. What could it be? Thanks! 1 Link to comment Share on other sites More sharing options...
Harry Pristis Posted August 12, 2022 Share Posted August 12, 2022 My guess is fish dentary that's been through the gut of a mosasaur or other predator. 2 2 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

I think you're right. I found more similar ones that look like fish jaw. Pictures before and after light cleaning. Link to comment Share on other sites More sharing options...
jpc Posted January 14, 2023 Share Posted January 14, 2023 I don't think it has been digested. I think what you see is simply extreme preservation in the Pierre Shale where Slow Walker collects. 1 Link to comment Share on other sites More sharing options...
