hoodle Posted May 17, 2019 Share Posted May 17, 2019 I found this in Niagara Ontario, in Upper Ordovician/Lower Silurian rock. The rock is mainly crinoid limestone. I'm not sure if it's a fossil. I wish I had a measurement, but I found it by accident, and didn't have a ruler. Link to comment Share on other sites More sharing options...

digit Posted May 17, 2019 Share Posted May 17, 2019 Appears to be "scuff marks" but their parallel orientation is curious. We have members in your general area who will recognize if this is something they are familiar with. @Kane @Malcolmt @Monica Welcome to the forum!
