Darbi Posted July 21, 2020 Share Posted July 21, 2020 Is this even a fossil? Ichnofossil? I'm stumped by this weird pattern. I found this ironstone in my parents' gravel driveway. Gravels were recently obtained from the local sand pit company here in Salina, KS., so I'm pretty sure this stone was transported in the river from Kiowa or Dakota formation (Albian) before being deposited.

Rockwood Posted July 22, 2020 Share Posted July 22, 2020 Sorry. I don't see any reason to think this is a fossil. It may be, but strictly mechanical processes are going to be tough to rule out. 2 Link to comment Share on other sites More sharing options...

Darbi Posted July 23, 2020 Author Share Posted July 23, 2020 Based on some of the responses (or lack of) on my previous posts, I sure do post some of the hardest objects to be identified. Link to comment Share on other sites More sharing options...

Perhaps physical processes would be a better term. Gravity, freezing, tectonic movement, heating and cooling, static electric charges moving small particles of sediment, anything but critters. 1 Link to comment Share on other sites More sharing options...
Darbi Posted July 24, 2020 Author Share Posted July 24, 2020 @Rockwood, thanks! I decided to leave it in the driveway. Link to comment Share on other sites More sharing options...
PaleoNoel Posted July 26, 2020 Share Posted July 26, 2020 While it resembles a section of Hadrosaur jaw without the teeth, the ridges are not as uniform as one would expect on the dinosaur. Here's mine for reference. 2 Link to comment Share on other sites More sharing options...
