fossils4fun Posted April 19, 2017 Share Posted April 19, 2017 This is a big boulder I happened on the other day that I thought was interesting, I guess it could be water erosion, just throwing that out there. Always interested to hear your thoughts. Also the picture beside the hand is some sort of trace fossil, would love to know the name, thanks for any info you can give.

The first one is a water erosion feature formed when water mixed with sediment swirls around in a rock and carves out a cavity. Link to comment Share on other sites More sharing options...
Peat Burns Posted April 19, 2017 Share Posted April 19, 2017 In the second photo, I see what appears to be a long-section of the bryozoan Archimedes (it's a bit blurry. It could be a nautiloid or even a big crinoid long-section, I suppose, too) as well as some crinoid columnals. Maybe a Mississippean Period deposit? 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted April 19, 2017 Share Posted April 19, 2017 I agree, ... this seems to be a cross section of an Archimedes bryozoan. Compare with this picture, from Pinterest.
