Quoted By:
Trimmers Rock Formation in Devonian shale and Siltstone near Millville PA. I work in solid waste as a CQA so i got out to a site where they were excavating the next cell for cover material while i was doing Liner work next cell over. I'd hop in and find alot of shell impints, hash and ripple marks along with crinoids. Found Burrows back here in the summer too. Some Pretty Tight dendrites as well, site management lets me have at it . The ripples were too big to take unfortunately. I got some from near Allentown PA anyway
