jeff510 Posted October 19, 2017 Share Posted October 19, 2017 I found this on the surface in Westfield, ny about a mile away from lake Erie. This area is all glacial till. Most of the sedimentary rocks strewn about here have fossils, trails, and or ripples. Anybody recognize this? Link to comment Share on other sites More sharing options...
Manticocerasman Posted October 19, 2017 Share Posted October 19, 2017 It is hard to tell from the picture. A close up of the fossil would help. My first guess would be coral growing old is mandatory but growing up is optional. Link to comment Share on other sites More sharing options...
Rockwood Posted October 19, 2017 Share Posted October 19, 2017 The scale (a mighty fine combination square by the way) suggest bryozoan. Link to comment Share on other sites More sharing options...
TqB Posted October 19, 2017 Share Posted October 19, 2017 Looks like Heliolites or similar heliolitid (tabulate coral) - the area between the large corallite pores has small coenenchymal ones. Tarquin Link to comment Share on other sites More sharing options...

My first thought as well, but doesn't the < mm size present a problem ? Perhaps my judgement of it is just off. Link to comment Share on other sites More sharing options...

The pores are just about 1mm which is fine - I've got a Wenlock Propora tabulata that's the same and Heliolites isn't usually much bigger.
