PRK Posted March 4, 2016 Share Posted March 4, 2016 Yes, crabs are certainly more commonly found in nodules. But they are not exclusive to nodules I've collected many in shale, AND in massive mudstones Link to comment Share on other sites More sharing options...
Auspex Posted March 4, 2016 Share Posted March 4, 2016 I think that the perception is that most are found in concretions, because dead crabs disarticulate easily when not so preserved. Parts of crabs are actually pretty common.

RJB Posted March 4, 2016 Share Posted March 4, 2016 I have found hundreds of crabs in concretions but once in awhile you find one that I call a 'floater' which is a crab in the matrix that is not concreted. RB Link to comment Share on other sites More sharing options...
JohnJ Posted March 4, 2016 Share Posted March 4, 2016 I think that the perception is that most are found in concretions, because dead crabs disarticulate easily when not so preserved. Parts of crabs are actually pretty common. I agree. ...And occasionally you can find them exceptionally preserved in shale and marl. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
