I drive 8 hours with a friend to a location he remembers from his childhood as yielding a lot. Oh boy it did. 100% worth the drive. Lake Huron, among the agates, pyrite, yooperlite, has some extraordinary Devonian fossils. All fossils were collected from the beach of his family’s property except for the fenestelid bryozoan, which was found at a gas station on the way there. please enjoy this collection of gastropods, petoskey stones, various tabulate corals, crinoids, stromatoporoids, bivalves, Brachiopods, tenteculites, horn corals, an unidentified agatized fossil in jasper matrix, and a pudding stone I felt like showing off too. Thanks! I highly recommend the area.

1.75 mm across silicified shell of a microconchid, a possible Lophophorate, that is sometimes referred to as a “worm tube”. It is encrusted on a Caninia coral. Found in the Pennsylvanian Naco Formation limestone from northern Arizona. Two microconchids are visible on the bottom of the lower right hand coral. https://en.m.wikipedia.org/wiki/Microconchida

From http://sciencythoughts.blogspot.com/2015/05/yuganotheca-elegans-early-cambrian.html: "An Early Cambrian Lophophorate Animal with affinities to Brachiopods and Phoronids. Lophophorates are animals which feed using a filter called a lophophore, which comprises a number of setae covered tentacles, to extract food from water. The group includes the shelled Brachiopods, the worm-like Phoronids, the minute Entoprocts, and colonial Bryozoans, and has been shown by molecular and embryonic evidence to be related to the Molluscs and Annelids. Within the Lophophorates the Phoronids and Brachiopods are thought to be closely related, with some studies suggesting that the Phoronids should be regarded as a shell-less subgroup of the Brachiopods."
