Recrystallized Fossil From The Permian Park City Fm. (Phosphoria), Central Wy
dazzle posted a topic in Fossil ID
Hi folks, I found these specimens in a Permian dolomud/wackestone in central WY (Fremont County). It is from the Park City Fm. (Phosphoria equivalent). I've attached photos of two different specimens which were found about 10-15 meters from each other in the same bed. I found a few other examples, and they were typically spaced about that distance apart from one another (in other words, they don't seem to form colonies), and they were by no means common. These appear to be recrystallized (see macro images). As I said, I think this is a dolowackestone "matrix" and there appear to be some silicified (chert) burrows nearby to the specimens, for what that's worth. Up is stratigraphic up in the photos (photos are perpendicular to bedding, i.e. cross-section view). I can't find anything like this described in the literature on the Park City/Phosphoria, and I was hoping that someone with a little more experience in Permian fauna (e.g. the Capitan reef builders) or other might have some insight. I was able to collect one specimen, which I plan on cutting and polishing, and also making a thin section for a closer look. In the meantime, any thoughts on what I might be looking at?? Thanks very much in advance!
