Rockpit Posted October 22, 2019 Share Posted October 22, 2019 Last time I was hunting fossils at Mazonia I picked up some rocks I found interesting. I don't know if they are fossils or not. The first is full of tiny holes I thought might have been caused by animals-or water . Link to comment Share on other sites More sharing options...
Rockpit Posted October 22, 2019 Author Share Posted October 22, 2019 The next one reminds me of wood-or is it just sediment deposits? Two sides of same specimen. Link to comment Share on other sites More sharing options...
Rockpit Posted October 22, 2019 Author Share Posted October 22, 2019 This is the last one. Link to comment Share on other sites More sharing options...
deutscheben Posted October 22, 2019 Share Posted October 22, 2019 The second one is an impression of fossil bark from a Sigillaria tree-like lycopod. I believe the example you have is of the internal bark with the outer layer gone, and it is known as Syringodendron. I have found similar fossils as Mazonia myself. The other two do not appear to be fossils to me. 2 Link to comment Share on other sites More sharing options...
Rockpit Posted October 23, 2019 Author Share Posted October 23, 2019 Thanks @deutscheben. Would this be from a weathered concretion or is it a different type of fossil? Link to comment Share on other sites More sharing options...
deutscheben Posted October 23, 2019 Share Posted October 23, 2019 These bark impressions come from a different layer than the ironstone concretions, I believe- the ones I have seem to be preserved in a lighter weight and more coarse rock, maybe a sandstone? Here are a few I found this spring at Pit 11: 1 Link to comment Share on other sites More sharing options...
Rockpit Posted October 24, 2019 Author Share Posted October 24, 2019 Very nice! I thought they might be sandstone so that is why I wasn't totally sure it was a fossil. I will have to keep my eyes open for these next time I go. Link to comment Share on other sites More sharing options...

Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
