MSirmon Posted April 25, 2017 Share Posted April 25, 2017 Picked up this double chert nodule a while back and have been alternately freezing and thawing. Finally broke in half between the nodes. From what can be seen is there value in continuing the process to break into the halves or is if hammer time? Link to comment Share on other sites More sharing options...
Fossildude19 Posted April 25, 2017 Share Posted April 25, 2017 Michael, My vote is for hammer time. Wait for some other opinions, though. Concretions/nodules are not my forté.

Plax Posted April 25, 2017 Share Posted April 25, 2017 Nice conchoidal fracture. Looks knappable. If you know anyone that makes bifacial tools they might want it. Around here some chert nodules start off as amorphous animals such as sponges. 1 Link to comment Share on other sites More sharing options...
