JimTh Posted October 20, 2018 Share Posted October 20, 2018 Looks kind of like wood, but I know it’s not. The only candidates I have found are stromatolites and bryozoa. I’ve been to St Leon probably 6 times now and never seen this before. 1 Link to comment Share on other sites More sharing options...

erose Posted October 20, 2018 Share Posted October 20, 2018 Tetradium. Most often lumped in with corals but it's taxonomic relations have been in question for some time. I lost track of it's current position. It has tiny coralites closer in size to the zooids of bryozoa but not bryozoa. http://strata.uga.edu/cincy/fauna/tabulata/Tetradium.html Were you high up in the section? These are most common in the Upper Whitewater/Saluda section at the top of the cut where many other colonial corals can be found. 3 Link to comment Share on other sites More sharing options...
FossilDAWG Posted October 20, 2018 Share Posted October 20, 2018 I find the argument that it was a red algae to be convincing. I'll have to look up the reference but H. Mirriam-Steele was the author. Genus names have to be unique within a Kingdom, and within the plants Tetradium was used for a tree before it was first applied to the fossil, so the name is preoccupied and not available for use for the fossil in question. The name Prismatophyllum is now the correct name for the genus, if you accept the hypothesis that the fossil is an algae. Don 3 Link to comment Share on other sites More sharing options...
Innocentx Posted October 20, 2018 Share Posted October 20, 2018 Another possibility, slim chance perhaps? See partway down page one.

All pieces found within about 12”. Link to comment Share on other sites More sharing options...
