Auspex Posted July 2, 2015 Share Posted July 2, 2015 The fluted columns look like urchin spines to me.

frankh8147 Posted July 6, 2015 Share Posted July 6, 2015 The third one looks like a coprolite to me; the last picture looks really intriguing - is that from Big Brook too? I have never seen anything like that from there. Link to comment Share on other sites More sharing options...
Darwin Ahoy Posted July 6, 2015 Share Posted July 6, 2015 The last picture are urchin spines. Somewhat common in certain areas. The first two are simply rocks. The third I am unsure. Link to comment Share on other sites More sharing options...

LawdogGRNJ Posted October 13, 2016 Share Posted October 13, 2016 The 2nd one looks to be a fragment of crocodile scale. The undersides are deeply pitted like that. How thick is it? Is there any patterning on the other side? Link to comment Share on other sites More sharing options...
Trevor Posted October 14, 2016 Share Posted October 14, 2016 I agree with Darwin Ahoy on the first two beings mere rocks or concretions. They are all too common. I additionally support Frank's thought regarding the 3rd item possibly being a coprolite. I have never seen urchin spines in NJ but I guess those are. : ) Link to comment Share on other sites More sharing options...
Coco Posted October 15, 2016 Share Posted October 15, 2016 Hi, Yes, on the last pic they look like sea urchin spines.
