The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids. By the end of the Devonian , several of these g

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

Over labor day weekend my wife and I decided to go camping at Crystal lake in the big snowy mountains near Lewiston Mt. We got there late Friday night to get a camping spot and Saturdays morning we decided to hike to some Ice caves that were 5 miles away. Along which there were ample exporsures of mississipian madison limestone. About a mile in I turned over a rock during a water break and there was my first brachiopod. Now that we knew what were were looking for we kept our eyes peeled and were rewarded with this large hash plate full of brachiopods that I think some are spirifera.

Hello all! I found this pretty cool bryozoan back in July and I decided to give it a prep. Its really easy matrix to work with so its good practice for someone like me who’s only done a handful of preps. Like my past preparations, this will all be done manually using mainly safety pins. Fenestella sp. ? Middle Devonian Hamilton Group Moscow Formation Windom Shale DSR, Lebanon, NY Enjoy!

I am studying a tiny area of a fossiliferous limestone rock from our yard and trying to determine the different items in it. The fan shaped item in the lower left corner didn't really look like the fenestella bryozoa that I am used to seeing, so I did a bit of research. I found a page with a similar image and was wondering if I am correct (or even close) in identifying that particular item as a cheilostome? Here is the page I was looking at: https://www.researchgate.net/figure/A-sample-of-bryozoa-sand-sample-number-71-from-a-depth-of-130-m-on-the-Lacepede-Shelf_fig1_238417060. Would the f

I am trying to wrap my head around what these things looked like in "real life" so I can recognize them better. This is a limestone rock with what I think are fenestella bryozoan fossils, found in Huntsville, AL. Mississipian age. This photo is looking down at what I call the "top" of the rock. The next photo will be from the side, looking at the same area but from the "inside" of the rock. Can anyone point me to a site where I might find a diagram of these to better help me understand what they looked like? Thanks! Ramona

This is my first post in the Fossil ID section - I am SO excited to find this resource! A have found a few very helpful folks in other places, but this group is a huge wealth of information! A bit of background - we moved into a house just outside of the city limits of Huntsville, AL, a couple of months ago. After finding a couple of fossils laying around in the yard, I decided to investigate the wooded area at the back of our property a bit more. Whoa!!! There is a creek bed on the property and the closer you walk to the creek the more rocks you have to walk over. Every single rock I pi

Tonight I found a new limestone ledge sitting 6 inches from a stream water level. My father and I started hammering away at the shallow edges and removed a ton of interesting specimens. While there were some nice cephalopods, lots of brachiopods and clams, this piece caught my eye. I’ve read about Bryozoa and I’ve seen similar things on fossil plates. I believe I remember seeing pieces of them in limestone while digging, but never anything big. So, is it a Fenestella? Or something else? I’ve never found one worth showing. I saw a species list for it and it is very long.

A small colony surrounded by Archaeocidaris debris. It shows the obverse side , i.e. the side with pores. It is preserved on the top face of a thin limestone lens that was overlain by shale. This is the most common fenestrate bryozoan in this area but the majority of specimens are found in shale and rarely split to show the obverse as it is the "stickier" side due to the pores.
