pondy Posted December 16, 2014 Share Posted December 16, 2014 Doing dredging in SW WI at depths to 80 feet and have found some what looks like walnut fossils? All different densities, some sandstone some very hard rock. Iv looked around and have not seen any other ones like this, any ideas?

pinkus Posted December 16, 2014 Share Posted December 16, 2014 my best guess is concretions. what was the surrounding material? rock, soil, sand? Link to comment Share on other sites More sharing options...

jpc Posted December 16, 2014 Share Posted December 16, 2014 are they really heavy? They look like barite nodules, but if they are not super heavy, they are something else. Link to comment Share on other sites More sharing options...
pondy Posted December 16, 2014 Author Share Posted December 16, 2014 Yea it looks like its been cracked open a little, that one is hard as stone Link to comment Share on other sites More sharing options...
Auspex Posted December 16, 2014 Share Posted December 16, 2014 are they really heavy? They look like barite nodules, but if they are not super heavy, they are something else. Either barite, or a mineral with a similar crystal form.

pondy Posted December 16, 2014 Author Share Posted December 16, 2014 The dark ones are heavy feels like stone, the sandstone ones are lighter. I don't know anything about this stuff we all think its walnuts? Is there value in them or should I toss or was thinking about seeing a rock geologist shop close by.

jgcox Posted December 16, 2014 Share Posted December 16, 2014 I would agree with some sort of mineral nodules-possibly barite. Link to comment Share on other sites More sharing options...
Fossildude19 Posted December 16, 2014 Share Posted December 16, 2014 Not fossilized nuts. Geologic in origin, almost certainly.

Auspex Posted December 16, 2014 Share Posted December 16, 2014 The value of these specimens is the value of the imagination you invest them. If you don't want to hang onto them, give 'em to a kid "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

izak_ Posted December 17, 2014 Share Posted December 17, 2014 One of them looks like a peach nut, lol. some look like fossils, others don't. Hmm (Bump) Link to comment Share on other sites More sharing options...
Scylla Posted December 17, 2014 Share Posted December 17, 2014 If you do a google search for "desert rose rock" you will see some similar formations. Some are barite and some are selenite. I certainly would take them to a local geologist or rock shop, they may be able to tell you more. Link to comment Share on other sites More sharing options...
