DustyFossil Posted December 15, 2015 Share Posted December 15, 2015 I found this rock in lanesboro Minnesota years ago in a riverbed. I believe a fossil identification book said it was a piece of coral stem? I can't remember very well, and I lost the book. I would love to know if anyone has any clue what it is. Thanks for reading! -the newbie Link to comment Share on other sites More sharing options...

fossilized6s Posted December 15, 2015 Share Posted December 15, 2015 Yup, that's a Rugose coral or better known as "horn coral". 1 ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...

minnbuckeye Posted December 15, 2015 Share Posted December 15, 2015 Welcome DustyFossil. Lovely Rugosa Coral. The bedrock in Lanesboro is early Ordovician, I believe Oncota formation of the Prairie Du Chin Group. To make a long story short, this means your coral did not live in the Lanesboro area. Most rugosas were in the mid to late Ordovician period. It likely was washed down the Root River from an area between Forestville and Preston, a much more fossil rich area than Lanesboro. I suggest checking out Bluff County Fossils on line for a great explanation of who, what, where and why for fossils in our area. 3 Link to comment Share on other sites More sharing options...

samlovesfossils Posted January 4, 2016 Share Posted January 4, 2016 It looks like Rugose Coral to me. Link to comment Share on other sites More sharing options...
SteveS Posted January 5, 2016 Share Posted January 5, 2016 Like everyone said, horn coral. That's the one thing I find a bunch of, though that one you got there is much bigger than any I find. Link to comment Share on other sites More sharing options...
