Ludwigia Posted September 3, 2015 Share Posted September 3, 2015 Talk about a lot of "paper work" from the researchers! Very impressive results! Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
minnbuckeye Posted September 3, 2015 Share Posted September 3, 2015 My day off yesterday was spent in the Decorah area, in a stream looking for fossils. It was too hot for us northerners to not be in the water. Got up to 60 degrees............I mean 90. I had done a little research on the eurypterid found. Everyone says Winneshiek Shale but the most intense info I discovered said St peter Sandstone. Are they the same? And no, I was not trying to find their "spot". I was not in the meteor strike zone. Just like to understand the geology of the area. Link to comment Share on other sites More sharing options...

JUAN EMMANUEL Posted September 8, 2015 Share Posted September 8, 2015 Where can I see photos of this eurypterid's fossil? I like the idea of Ordovician sea scorpions. Link to comment Share on other sites More sharing options...
