Caroboneferous Posted August 20, 2021 Share Posted August 20, 2021 I found this piece outside Kansas City Missouri on the Missouri River. Does anyone have an idea what it could be, looks sort of like coral, haven’t come across this before. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted August 20, 2021 Share Posted August 20, 2021 Mmm. Seems to have pillars, canals and mamelons. I'll go, cautiously, with stromatoporoid. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted August 21, 2021 Share Posted August 21, 2021 (edited) It looks like prisms of calcite deposited in an open space (cave?). The botryoidal surface is the “top” growing surface. Stromatoporoids are not present or are very rare in the Carboniferous. Here is a piece from the Carboniferous of Arizona: Edited August 21, 2021 by DPS Ammonite 1 My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere. Link to comment Share on other sites More sharing options...
Lone Hunter Posted August 21, 2021 Share Posted August 21, 2021 I have similar example of that form of calcite on a stone, I have found large surface areas of this on top of shale. Link to comment Share on other sites More sharing options...
