Bob Saunders Posted September 22, 2019 Share Posted September 22, 2019 I found this in rail road ballast, so I do not know original state. I believe more western USA. any ideas on possible location and other comments? Link to comment Share on other sites More sharing options...
Rockwood Posted September 22, 2019 Share Posted September 22, 2019 Pretty sure this is a colonial (branching) rugose. 1 Link to comment Share on other sites More sharing options...
Pippa Posted September 22, 2019 Share Posted September 22, 2019 3 hours ago, Rockwood said: Pretty sure this is a colonial (branching) rugose. Ha, I just posted a Fossil ID question about a very similar grey rock I found at a lake Michigan beach in Illinois, with similar imprints. I had originally thought I had crinoid molds and dismissed the possibility of it being coral, due to the waviness of the "stems". I knew of colonial rugose corals, but never heard of them as "branching". Rockwood, I think you just answered my fossil ID question too! Thanks. Off to do some google research on colonial branching rugose corals. Link to comment Share on other sites More sharing options...
Rockwood Posted September 22, 2019 Share Posted September 22, 2019 Some northern Maine loggers had pushed a huge boulder out of their way. My first real exposure came by the ton. Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted September 22, 2019 Share Posted September 22, 2019 And it's quite possibly from Wisconsin as opposed to out west somewhere. That type of preservation is common in the Great Lakes region, especially Superior, Michigan and Huron. Mark. Fossil hunting is easy -- they don't run away when you shoot at them!
