WI-fossil-guy Posted August 25, 2019 Share Posted August 25, 2019 The rock I am posting today does not contain calcium. I does contain agate. It is uniquely formed and is very laminated both on the surface and throughout the agate portion. What do you think, fossil algae or pseudofossil? or Link to comment Share on other sites More sharing options...
Rockwood Posted August 25, 2019 Share Posted August 25, 2019 One vote pseudo. Mostly based on the hollow center. Link to comment Share on other sites More sharing options...
grandpa Posted August 25, 2019 Share Posted August 25, 2019 Pseudo fossil from the same formation as the group of chert nodules you asked about last week, I'll wager. Link to comment Share on other sites More sharing options...
