Calling on the usual crowd to either confirm or refute my meager attempts at identification. I'm not sure on any of these three. @bigred97 @connorp @deutscheben @fiddlehead @flipper559 @Nimravis @RCFossils @stats @TheRocksWillShoutHisGlory I truly appreciate your input. Thank you in advance for taking a look. And anyone else who would like to offer an opinion -- thank you as well.

Hi all, this strange piece came with a batch of edestus fossils that were found in a coal mine in Illinois. Have no idea what it could be, the front seems to be coated in black coal mostly while the back has what appears to be ridges. All I know about the location is it was found in a coal mine along with some edestus teeth that is Carboniferous in age. Hoping with some help to get to the bottom of this mystery.

Help! I'm not sure if these are fossils or not. I'd like to think they are, just no idea what they are. I'm also freeze thawing a few still. We didn't find much while we were there. But did find just a few nodules.

About a month or so ago I found something on the side of the road by my house. I am somewhat familliar with the indigenous rocks in the area, however, I am not an expert. This "thing" that I found has layers of some sort, and in places looks like the shed skin of my leopard gecko (it's not), sandwiched between other bumpy layers. The crispy, skin like stuff seems to flake off and folds over in some places. In another area, there seems to be even rows of "pores" that are aligned perfectly. The pictures don't really do it much justice though. I wish they were better. I know that "on the road" is an odd place to find a fossil, but I walk a lot and had never seen it there before. How it got there I can not say, but I guess it adds to the mystery. Anyways, I did a little bit of research and thought it could either be a skin fossil, scute, or a bacterial mat. If anyone knnows what it is, please let me know. I won't be too heart broken if it is "just a rock". At least I'll know. Jessica
