cytros Posted August 23, 2019 Share Posted August 23, 2019 I found this in Big Sky, MT and after cleaning it up a bit, saw what looks like a couple crawfish tails and possibly a head of a vertebrate. It is 4cm by 3.5cm and no more than 1cm in thickness. Link to comment Share on other sites More sharing options...
grandpa Posted August 23, 2019 Share Posted August 23, 2019 What I think you have there is a trace fossil of possibly burrows. 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted August 23, 2019 Share Posted August 23, 2019 Cropped and brightened. I would agree with ichnofossil/trace fossil of filled in burrows.
