New Members mathmagical Posted March 31, 2013 New Members Share Posted March 31, 2013 I found this on the shore of Lake Ontario, near Oswego, NY. It's roughly an inch and a half long. Any ideas? Link to comment Share on other sites More sharing options...
kwilson Posted March 31, 2013 Share Posted March 31, 2013 Nice longitudinal section of an orthocone nautilus. The siphuncle (running down the middle), and septa separating the chambers showing very nicely! See: http://en.wikipedia.org/wiki/Nautiloid Karl A.

PA Fossil Finder Posted April 1, 2013 Share Posted April 1, 2013 Yes, it looks like a nautiloid that has been turned into a geode. Stephen Link to comment Share on other sites More sharing options...
