I returned home two weeks ago from a two week long fossil hunting excursion out west. Like my trip two years ago, I drove all the way from my home in southeastern New York out to northcentral Wyoming with many stops along the way. The first day was on and off rain from here to Toledo, Ohio where I stopped. Next day drove through northern Indiana and passed through Chicago, finally stopping at my cousin's in Madison, Wisconsin. Late morning, the next day, I met up with Mike (Minnbuckeye) in Fennimore, Wisconsin and he took me to two sites of the Upper Ordovician Platteville Formation where we spent the afternoon collecting. Here is a photo of one of the sites with Mike and finds that we both made. Mike was generous and gave me a number of specimens. As you can see there are a few nice hash browns, I mean hash plates, trilobite parts, brachiopods, nautiloids, including the unusual Gonioceras occidentale (the fossil and counterpart), plus the gastropod, Sinuites, and the ostracod, Eoleperditia fabulites.

Over the Fourth of July weekend, I made my annual pilgrimage to Western NY for a family get-together/reunion. I have been going to the Rushford Lake area for over 20 years now. I usually take a partial day to do some fossil hunting further north and west of that area, closer to Buffalo, NY. This year, as a change of pace from hunting my usually Middle Devonian haunts, I decided to try to get back to a site I went to last year with Jeffrey P that exposes some Silurian aged sediments. I've come across differing opinions on what stratigraphy this site exposes. Some consider this site to be part of the Clinton Group and Lockport Formation, while others consider it to be a Rochester Shale/Lewiston Member exposure. Either way, these fossils are Silurian in age. This is a surface collecting locality, where I get down on hands and knees to search for tiny fossils that have weathered out of the under-laying limestone/shale areas on a hillside. There are chunks of matrix to collect as well, that show hashplates of bryozoans, crinoid, and shell material. I arrived to the site a bit after 8:00 AM. I took my time, and scoured the hillside with a pair of +3.00 reading glasses on, to better see the tiny fossils. It stinks, getting old! This is what the area basically looks like: Rock hammer for scale lower center. As I hunted, I threw interesting looking fossiliferous chunks of matrix down to the bottom of the hill, as I explored the surroundings. I took a few small chunks home to put in the garden to weather out some. I came across a few interesting/photo worthy flora and fauna while hunting. A nice Common Daisy: And a little Yellow caterpillar - possibly a Tiger moth caterpillar: Here he is, on the ground, looking for fossils with me. Note the large amount of ramose bryozoan bits, scattered along the ground. There are also some fenestrate bryozoans, and a Leptaena brachiopod visible in this picture. . I spent about 2 to 2.5 hours at the site, moving along on hands and knees, picking up whatever looked interesting. I found quite a few things. Some corals, both Favosites parasiticus, and Enterolasma caliculus. Ramose and Fenestellid bryozoans. A number of small to miniscule brachiopods - Rhynchonellids, spiriferids, and strophomenids. A few bits of trilobites, both Dalmanites and Flexicalymene. A gastropod, which still needs some prep, and a few crinoid bits. (My identifications come from THIS WEBSITE. ) Here is a group shot of my loose finds. I will have to take some pics this evening or tomorrow of my matrix pieces. I found a really nice, large plate of a crinoid calyx. cystoid! Caryocrinites ornatus. Ruler is in CM. Here are the Trilobites: And a Leptaena with a crinoid (or cystoid?) plate attached, and a tiny brachiopod- unidentified at the moment. More to follow.

I’ve finally put the last touches on the Paleozoic Shelf for my at-home fossil display, and I’m very happy with how it turned out. It includes fossils from every period of the Paleozoic Era, except the Permian (which has its own shelf). It’s not every Paleozoic fossil I own, but it’s a curated collection of some of the ones best suited for display. They fossils are roughly organized such that they get younger as you go left to right! The large artwork on the background is a print of a piece done by Rob Sula, depicting a Devonian scene. Plus a better view of the Cambrian Explosion case: I love curating my little museum, and I hope you all could get some enjoyment and inspiration out of this post!

As I wrote in my previous Deep Springs Road Quarry thread, the very next day I was off to Kentucky. Like my other trips there, the purpose was primarily family/social. My father was turning 95. Between spending quality time with family, I was able to visit a couple of my favorite roadcuts exposing Paleozoic marine sediments and collect specimens I don't have access to in New York. The first site I visited was the very first site I was to acquaint myself with in Kentucky years ago. It is located near the town of Leitchfield, about a half hour from my family in Elizabethtown. Years ago, it was my very first exposure to rocks of the Mississippian Age and it has been a favorite ever since. I've visited this site every time I've been to Kentucky in the past seven years. The site, more specifically, is an Upper Mississippian marine site, the Leitchfield Limestone, Glen Dean Member. Since I've been there last year, they've done a bit of work on the road, installed curbs and a sidewalk, severely restricting the offroad parking situation. It also appears they are planting grass which will limit the collecting area. Fortunately, there was enough room to park my car and the collecting area was still open. The weather was pleasant and sunny as I wandered up and down and across the slopes of weathered shale and limestone exploring and searching for specimens. There were a number of rugose corals present, though most were badly weathered I ended up keeping this one- Zaphrentoides spinulosum:

This seems to be some kind of fossil soup, I can see many kinds of aquatic fossils, and bore holes. My question is, is the underlying structure limestone, rotten and fossilized wood, or degraded bone? Or something else. Found along a beach ridge of Lake Agassiz in North Dakota.

My annual excursion to visit my family which migrated to Kentucky years ago took place at the end of October into November, lasting two weeks. Of course, the planned trip took me in the vicinity of some excellent fossil bearing sediments and though quality time with family was the primary purpose, I did hope to add to my collection. All of the spots I visited were ones I've been to before; however, the first stop was a new one for me- Paulding, well known and documented on the Forum for its Middle Devonian marine fauna. I drove from the suburbs of New York City for almost eleven hours, raining most of the way, arriving at and spending the night at a hotel in Defiance, Ohio. Paulding was about fifteen minutes away. Drove there the following morning, It was a brisk forty degrees, mostly cloudy, but sunny at times. A TFF member I was supposed to hook up with there unfortunately had to bail last minute. A nearby quarry which exposes the famed Devonian Silica Shale had, years ago, stopped allowing collectors to hunt there. There was a big outcry and the quarry set up a fossil park dumping fossiliferous rock onto a property they owned which the public were free to collect from. Much of it is now overgrown and much of the rock has been reduced to gravel. However, there are still many fossiliferous chunks out there if one is willing to look.

Some recent Upper Ordovician finds at Mimico Creek, Toronto
Rogue Embryo posted a topic in Fossil Hunting Trips
First, if anyone in the Toronto area is interested in going fossil hunting along Mimico or Etobicoke Creeks, I'd welcome the company! Before I get to a couple of better finds, I'm curious to know what the black fragments are below, which I often find embedded in the shale. Can someone please give me a clue about these? Some orthoconic cephalopods: The next two are the same fossil from different perspectives: Some bivalves: Bryozoans: Cheers, Camille

Found this while hunting for fossils in South-Central Minnesota. Most of the fossils we found were easily identified brachiopods.The shape of this rock was very different from those around it. The curve was so uniform, maybe it's just a rock. I am less than a novice at this so I really don't know. It also appears to have some plant fossils on it and between some layers. Maybe Bryozoan?? I would really appreciate some help in identifying any feature in the picture. Thank you so much! The first photo is the back, second picture is close up of the front, third picture is broken side showing layers. The other sides are smooth with no lines or visible patterns.

The lower Hunter Valley is underlain predominantly by Permian strata, and encompasses the region around Newcastle, NSW, Australia. It is here that a diverse fossil macrofauna can be found at a disused quarry standing on private property. Mulbring quarry is characterised by excellent exposure of the Permian strata with macrofauna dominated by abundant bryozoans and brachiopods, associated with bivalves, gastropods, and echinoderms. With the weather typically windy this time of year it was no surprise when we hit the black top with a strong westerly wind blowing, fortunately the sun was shinning. The plan was for my family to meet up with my retired geology teacher friend and his wife at the gate to the property. Two weeks earlier I received access permission from the property owner and we met my friends at the gate and headed up the track. Stepping out of the car upon arrival at the quarry our excitement peaked quickly with fossils bearing rock lying all around us. It didn't take long for my friend Col to find a lovely Bryozoan, my find with a specimen of fossil debris, including fragmented gastropods, isolated echinoderm ossicles and small brachiopods (pictured Mulbring 001) followed quickly after. We spent the next couple of hours fossicking around, then stopped for a well prepared picnic in the Australian bush. A few more hours of fossicking revealed the beautiful Bryozoan also pictured (Mulbring 002). These fossil beds also contain a particularly high abundance of fenestellid bryozoans and brachiopods (spiriferides and productoids), with bivalve molluscs the next most abundant. Minor groups include gastropods, rostroconchs, corals, trilobites and several types of echinoderms. Sadly, the trilobites and intact echinoderms evaded our gaze. I've already began my visit to one of the State's Jurassic sites early next year! Cheers Adelotus

Hello fellow fossil peeps, I am finally adding myself on here as I was told to do by Asa Kaplan almost a year ago. I love finding fossils and making new discoveries or new to me discoveries. I love to learn and I am joining here to learn more and possibly spread some of the things I have learned as well. I live in Missouri south of St. Louis in Jefferson County. This is primarily where I collect in various groups and formations including the decorah group, plattin group, kimmswick fm, warsaw fm, fern glen fm, and St. Louis fm. Favorite fossils right now are cyclocystoids. I have found the one in my profile pic and several hundred more individual submarginal ossicles and 2 more partially articulated rings (one that is also nearly complete). 2nd favorite thing to hunt for is either cephalopods or trilobites and it depends on my mood and location I am searching. Locally we can find a lot of straight cephalopods such as endoceras, actinoceras, cameroceras but coiled nautiloids and ammonites are rare to non-existent in these formations. In Missouri full or even close to full trilobites are also rare finds although I have been lucky to find a few over the past 2 years they are still very rare. Bryozoans and the wild diversity are also a favorite and very diverse in my area. Archimedes, Evactinopora radiata, diplotrypa, and others are prevalent locally. Thank you,

Paleozoic Adventures in Kentucky and Tennessee October 2021
Jeffrey P posted a topic in Fossil Hunting Trips
Hi Everyone, In the latter half of last month I took a two week trip to Kentucky and Tennessee. My sister, her husband, two of her adult children, and my parents all live in the Elizabethtown/Louisville area and I was able to spend some quality time with them. Fossil collecting was also part of my agenda. Herb, my primary fossil collecting partner in Kentucky and I had a three day trip down to Tennessee planned. Before I went on that expedition, I was out with my brother-in-law driving around central Kentucky. He dropped me off for 20 minutes at the Upper Mississippian site at Wax where the Glen Dean Formation is exposed in a roadcut. I picked these up:

Taking advantage of my time spent home, I finally got a couple of glass display cases to showcase fossil specimens from my collection. Finding ones that were affordable and blended with the style of our home, was challenge, and I took my time choosing. Despite a bit of criticism I receive from some of my fossil collecting friends, I am a generalist collector who doesn't specialize in anything. Having said that, my collection does feature some rare faunas; Devonian and Cretaceous bivalves, Lower and Middle Devonian brachiopods and gastropods, Cretaceous vertebrates, etc. The focus is largely on fossils of the Northeast (New York, New Jersey, Pennsylvania, Connecticut, Maryland, and Eastern Canada), but a number of trips to the Ohio Valley, Texas, out west, and Germany have expanded my collection which is about 90% self collected with remaining fossils primarily gifts from generous friends. There is only one purchased fossil in the display and one I traded for. I ended up with twelves shelves- ten devoted to animal life (seven of those are invertebrates), and two for plants. I was seeking to emulate the old style of specimen display that one might encounter in a 19th century museum, when displaying specimens was the priority. I didn't and couldn't display my entire collection which is too large, so I picked representative specimens to tell the story of the vast variety of prehistoric life on earth. Some of my best specimens didn't make it into the display. These are the cases which are situated in our finished basement:

Hi Everyone, I took a 2 week trip to the Ohio Valley, arriving back in New York about a week ago. It was primarily a family visit since many of my relatives now reside in the Elizabethtown, KY area. However, the Ohio Valley, as some of you know, is very rich in Paleozoic fossils and I just had to make a few stops on my way there and back as well as between family engagements. I will try to share enough to give you all a gist of it: It was a long day's drive from the northern suburbs of New York City to Richmond, Indiana where I spent the first night. The next day I was headed down State Road 101 to Garr Hill, to collect in the Upper Ordovician Liberty Formation. It was my first time at the site and everything I found was collected from loose rocks at or near the base of the outcrop. A couple of pictures:
