I posted this image in the prep thread and I was widely stated to be an Ichnofossil of infilled burrows. I really don't want to be "that guy" that questions expert opinions, but I'm curious; the burrow seems to have attached branches and areas of tiny "grassy" masses adjacent to it. Could they be crinoid segments/branches and pinnules? I have seen photos of chondrites that have the same kind of appearance. I include 3 of my photos, including one through the eyepiece of my scope, and one internet photo of crinoid pinnules.
Thanks. I'll happily accept your opinions, go away now, and not be a pest any further.
