Kim Ellis Posted June 11, 2017 Share Posted June 11, 2017 After my wonderful introduction yesterday, my research on chert discussed fossiliferrous chert. All indications in this chert lead to that. Could this have devonian fossils? Seems to have the same repeating pattern. Link to comment Share on other sites More sharing options...

Rockwood Posted June 11, 2017 Share Posted June 11, 2017 I don't see any fossil here yet, but you have the right idea. Patterns that don't look quite random enough to be just minerals should always catch the eye. Link to comment Share on other sites More sharing options...
Yvie Posted June 11, 2017 Share Posted June 11, 2017 I bash my chert again to get new breaks and put it under the microscope,some produce larger pieces like sponges.Be careful and do it outside with eye protection ,I wrap it in an old towel and try to aim at a fault crack.

doushantuo Posted June 11, 2017 Share Posted June 11, 2017 spiculitic chert is biogenic,as the name implies(sponge spicules). The silica in this world is basically from rhyolitic volcanism,or from siliceous organisms Link to comment Share on other sites More sharing options...

Kim Ellis Posted June 11, 2017 Author Share Posted June 11, 2017 This is a piece I tumbled... I have had this rock for almost a year. A friend found it in our mountains and smashed it with a hammer. It was 1 big rock. Here is another aspectod the tumbled piece Link to comment Share on other sites More sharing options...

Kim Ellis Posted June 12, 2017 Author Share Posted June 12, 2017 Ok 1 more... just can't drop this... Do you agree that this is a fossil. Same rock Link to comment Share on other sites More sharing options...
Wrangellian Posted June 12, 2017 Share Posted June 12, 2017 Nothing I see here jumps out at me as being fossil, I agree with John.. polishes nice! As far as I know, fossils in chert don't generally jump out at you, in other words they don't pop out of the rock as you break it - you might need to get some polished slices and magnification to see anything. Look up 'Rhynie Chert' for examples. Link to comment Share on other sites More sharing options...
