enoscrawler Posted June 18, 2014 Share Posted June 18, 2014 The one on the left kind of looks like a jaw bone Link to comment Share on other sites More sharing options...
Plax Posted June 18, 2014 Share Posted June 18, 2014 two partial clam steinkerns are a possibility, one on left could be very worn and phosphatized agerostrea, one on right has also been borrowed, if the one on the right is actually a weathered and worn piece of shell the burrows could represent a sponge such as cliona, if you show a pic of the other sides it may help Link to comment Share on other sites More sharing options...
Carl Posted June 18, 2014 Share Posted June 18, 2014 Sorry, I'm not seeing anything in the first picture. There are many bits like this in Big Brook that are usually interpreted as fairly modern root casts: The heavy iron content of the sediment causes adherence of sand around buried roots that later weather out into the brook. The other piece looks like the mold of a branching network of a bryozoan colony. I guess it could also be a burrow of some kind but that would be pretty hard to tell.
