The attached photo is a group of Thamnopora corals found in the Devonian Martin formation - dolomites of central Arizona's Verde Valley. There is also a group of tabulate corals that I suspect are Syringopora sp.. but some collection notes by others don't show this genus, but they do show Aulopora sp. as found in the same location. See the small worm-like cluster near the center of the image. Can any of you confirm which genus is in the image?
