ScandinavianBleu Posted July 3, 2019 Share Posted July 3, 2019 In my hunt to find things on my shoreline Ottertail county Minnesota on North Turtle Lake I have collected what I have been told by the University of Minnesota are bison bones. I broke my wrist collecting this spring so I have been reduced to looking over my finds and I noticed for the first time what looks like cut marks. I have also found various tools including a core rock. Does anyone know if these are marks made by a tool? Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted July 3, 2019 Share Posted July 3, 2019 It's possible, but those marks are suspiciously parallel. Would be difficult for a human using a tool to make such incredibly precise incisions. It's difficult to get them lined up so well when you try to, let alone when butchering some food. I'm trying to imagine what else may have caused these marks but I'm not coming up with much at this time. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

Al Dente Posted July 3, 2019 Share Posted July 3, 2019 The marks might have been made by a rodent chewing on the bone. Link to comment Share on other sites More sharing options...

If I didn't know better I'd say it's a bar code. 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...

Harry Pristis Posted July 3, 2019 Share Posted July 3, 2019 The crucial image is slightly out of focus, so it is impossible to assess the nature of the marks. Here's an example of butcher marks from a stone tool: 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...

ScandinavianBleu Posted July 3, 2019 Author Share Posted July 3, 2019 I really appreciate all of the replies. I was hoping I finally found something really cool...I will have to wait to get my cast off and go back to searching . I did find a rock ,flint I think ,very hard and shiny with chonchoidal fractures so I was hoping... Link to comment Share on other sites More sharing options...

No, but the animal was butchered no matter what the end result. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

westcoast Posted July 3, 2019 Share Posted July 3, 2019 That bone looks like it is quite tumbled and worn and the scar appears to post date the wear suggesting it is a later feature not connected to butchery. 1 Link to comment Share on other sites More sharing options...

Color is about all I see that is different. Link to comment Share on other sites More sharing options...
