NWARockhound Posted July 26, 2020 Share Posted July 26, 2020 I was in my favorite creek bed for ammonites and nautiloids in a nice bed of Fayetteville Shale, when I found this fascinating little rock. I think I read somewhere that you can find fish skin in the lower Fayettteville shale? Whatever it is I've never found anything like it. It's about 2in long, .5in wide, 1/8in thick. There's a section running through it that looks like a core, but it didn't photograph very well. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted July 26, 2020 Share Posted July 26, 2020 (edited) It is a coalfield plant fossil, possibly a branch of Lepidodendron which has diamond-shaped leaf scars that spiral up the stem.

connorp Posted July 26, 2020 Share Posted July 26, 2020 Welcome to the forum. It looks like plant material to me, maybe something like Lepidodendron. In the future, it's helpful to include the age of the rocks you're hunting in as most people will be unfamiliar with the specific formations in your area. 1 Link to comment Share on other sites More sharing options...

That makes sense to me, I'll be sure to do that in the future, thanks for the tip and for the ID! 1 Link to comment Share on other sites More sharing options...
Bobby Rico Posted July 27, 2020 Share Posted July 27, 2020 @NWARockhound Lepidodendron is also sometimes referred to as scale tree. It is a favourite of mine and I have 4 of 5 pieces in my collection. Link to comment Share on other sites More sharing options...
