RocksAndFossilsHunter Posted September 5 Share Posted September 5 Found this in Indiana, I was wondering what it was. I know it’s some type of coral, but I’m not sure what it exactly is. Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 5 Share Posted September 5 Some sort of colonial rugose coral. Possibly something like Siphonodendron sp. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

TqB Posted September 5 Share Posted September 5 I agree it's a branching colonial rugose coral. Eridophyllum maybe (Devonian). Siphonodendron (Carboniferous) has a slightly different internal structure, usually with a central columella which doesn't seem to be present. There are many that look similar to these and you'd really need to know the age to narrow it down. Indiana has a huge range of rock ages so an approximate location should help. 2 1 Tarquin Link to comment Share on other sites More sharing options...

I found them in a parking lot, so I’m pretty sure they were in a quarry. Link to comment Share on other sites More sharing options...

Mark Kmiecik Posted September 5 Share Posted September 5 Likely to be Syringopora sp. in that area. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
