Kyleigh Hope Posted May 2, 2020 Share Posted May 2, 2020 In my backyard, I found this rock that was uncovered by recent rainstorms. It has strange "zig-zag" marks along some of the sides, and looks to be porous. I cleaned it off and did a tongue test, and the majority stuck to my tongue. The part that didn't was the noticeably smooth part shown in what I believe to be the 6th photo. My question: Is this just a rock, or could it be something else? 1 Link to comment Share on other sites More sharing options...
Darbi Posted May 2, 2020 Share Posted May 2, 2020 Welcome to TFF! It looks like a cone-in-cone; which, it is a type of calcite structure. It's not a fossil, unfortunately. As long you keep looking, you will find fossils eventually! 5 Link to comment Share on other sites More sharing options...
