To really start the summer off well, I went recently to a Bond Formation rock formation of Pennsylvanian age, around 300 Million Years ago, in Oglesby Illinois with a few friends. The trip was overall good, though I almost fell off the rocks a couple times. It was a bit hot but overall I think I got a decent amount of fossils for the day. I found a decent amount of Crinoid stem fossils, of which here are a few of them: Found lots of what I think are Chondricthyian teeth (Chomatodus, Gilkmanius, etc.). But I would like help identifying them!!! Unknown Specimen 1

Been meaning to post these photos a while back but got caught up with preparing for Spring Break. Here's some more fossils myself, @Tales From the Shale, and another friend found a few weeks ago at a Pennsylvanian age, around 300 Million Years ago, rock formation in Oglesby Illinois. I hope these specimens could be Identified properly. I have no idea what this specimen could be? Some brachiopod and possible Chomodus sp. bits I would like a proper ID for. Possible brachiopod? Possible brachiopod or shell crushing chondrichthyan tooth? I don't know what this is (maybe a part of a Ctenacanthiform tooth or part of a shell crushing chondrichthyan tooth)? Brachiopod specimen I would like a proper ID of.

Fossil Hunting Trip on the shores of Lake Michigan, Illinois December/5/2022
Joseph Fossil posted a topic in Fossil Hunting Trips
On Monday I went on a little trip to one of my top secret places to fossil hunt on the shores of Lake Michigan. It's a small beach in Northeastern Cook County, Illinois which I've always found lots of Silurian aged fossils. (1) This trip was no different!! https://silurian-reef.fieldmuseum.org/narrative/392 I found a large amount of small but pretty interesting Silurian fossils which demonstrate the diversity of reef supported aquatic life in the Chicago land area 444 to 419 million year ago during the Silurian era!

Bond Formation Chondrichthyan fossil tooth from Oglesby, Illinois
Joseph Fossil posted a topic in Fossil ID
During my trip to a Bond Formation Rock formation in Oglesby, Illinois on October 8th, 2022, one of the limestone blocks I found had a small reddish fossil sticking out on the side of the rock. It was about 2mm in length so pretty small. I thought it was interesting so I brought it back with the rest of the fossils collected that day. There was not a lot of room in my garage for the block so I put it outside on a supply bin for a while. The next couple of days, It rained ALOT. One day I remembered that the calcite in limestone dissolves in rain, so I went out that night to check on what could be revealed. I was pleasantly surprised at what I found! The rain had exposed more of the fossil to the surface. I believe it's a Chondrichthyan tooth or a piece of a brachiopod, but I'm not 100% sure so I was wondering anyone could give a proper ID for the specimen?

How Fossiliferous are Cambrian Period Rock Formations in Illinois
Joseph Fossil posted a topic in General Fossil Discussion
I've recently been looking over the geologic formations in Illinois and I found one that's a bit interesting - it's a Cambrian period outcrop but it seems to be a bit small, only found in parts of Ogle and Lee County, Illinois. http://ebeltz.net/firstfam/1stfam.html https://www.osti.gov/servlets/purl/1202269 https://ilstratwiki.web.illinois.edu/index.php/Cambrian_System I haven't heard of a lot of fossils coming from this area so I'm wondering if anyone's been fossil hunting in that region of Illinois before and how common are Cambrian Fossils from Illinois's Ogle and Lee Counties? -
Hi! Me and @Tales From the Shale are actively thinking of going on a fossil hunting trip in Alton Illinois (right by St. Louis, Missouri) this week to analyze the Mississippian period St. Louis limestone and I'm wondering if anyone else has gone down there? https://www.mindat.org/feature-4232679.html We're specifically looking for fossils of the Meramac group and though we have a quarry or two, we're thinking of also checking out any road cuts in the area. I'm wondering before we go on the fossil hunt (likely this Saturday), could anyone offer some info on any good road cuts in the Alton area as well as quarries and if there are also a descent amount of fossils in the Spergen limestone too?

Hey all, I’ve found a number of these pretty geodized shells with incredible smoky and clear quartz crystals in the Kansas City area. Have you guys ever found anything like these?

I've been trying my hand at prepping this hash plate that I found on the Whitewater River in Southeast Indiana. Gotta do something when the river is high and the weather sucks!! There is a lot of bits and pieces going on in this one and the color of the fossils are odd compared to the matrix they are in which is really soft. Thought I'd share, what caused this jumble of fossils, and what do you see?

So I’m still snowed in so here’s a trip from warm Early June. My friends and I wanted to hit all the closest rock locations around Salt Lake City and search for fossils and cool sedimentary geology (a couple of them being sedimentary geologists). We visited the Southern Oquirrh Mountains and a few canyons over on the east side of the valley at the base of the Wasatch Mountains. Here are the stratigraphy columns for both provided by Geolgic History of Utah by Lehi F. Hintze and Bart J. Kowallis. I did not lead this trip so I am not certain which rock layers the fossils were each from (I’ll point out the ones I do know) but I’ll say we went through the Cambrian and Mississippian in the Oquirrh Mountains and basically everywhere on the Salt Lake City column.

A bit of a weird trip yesterday. I combined two hobbies at the same time. You may have seen me wondering what fossil hunting was like on a boat. So I tried the desert version of a canoe: a mountain bike. This is part of the ongoing research on Fossils of Stansbury Island that @Earth Chemistry is conducting there (See thread here). I packed my bike and back pack and drove to the southern tip of the island. We had these layers down before my trip. Red is no fossils, green is fossils.

For all of us that are feeling the the effects of crystallized hydrogen dioxide here's a photo of a Silurian-Bloomsburg Formation shale bed (this frame of view is about 3 sq/ft). The hillside road cut site is few miles from me and a great place to sit on a sunny afternoon. Here's the fun part this spot is loaded with weathering out brachipods, coiled & spiraled gastropods, straight shelled cephalopods, corals, crinoids etc. I collected over 15 different fossils from this one site. Most (except the cephalopods & some corals) are small enough to sit on a fingernail with room to spare! Have fun on a virtual (photo) fossil hunt.

A quick trip through the Confusion and House Ranges, Utah
DeepTimeIsotopes posted a topic in Fossil Hunting Trips
The Confusion Range and the House Range sit in Western Utah. The House Range is farther east closer to Delta, Utah than the Confusion Range. Parts of the Confusion Range are basically on the Utah-Nevada border. Both mountain ranges though have spectacular fossils. The House Range is basically all unfaulted Cambrian age layers and fossils pop up in several of the rock layers there. The Confusion Range, though, is broken up by many faults and everything from the Cambrian to the Triassic is present. Here's a short stratigraphy section marked with the layers we visited. We went to three different sites. A Cambrian site next to U-Dig fossils to sample the Cambrian explosion, and Ordivician site at Fossil Mountain (what better place to find fossils then a mountain named "fossil" mountain) to sample the Great Ordivician Biodiversification Event, and finally a time where 90% of all marine was wiped out, the Permian Period and the Gerster Limestone.

Last week, after checking the weather wunderground numerous times, I decided to drive 3.5 hours from Chicago to St. Paul Stone Quarry. It was the last "open house" day according to the ESCONI website. I arrived at 7:45, the first and only person there. Shortly thereafter, after a brief safety instruction, I followed the manager to the collecting site, heaps and heaps of Waldron shale. Even though I dressed in layers, I still had to take breaks and warm up in the car for a few minutes, but I much rather prefer collecting in cold weather as opposed to hot summer sun with mosquitoes, any day. It didn't take too long to start finding fossils. Here are just a few of my finds: Eospirifer Platystrophia brachiopods with pyrite Platyceras niagarense encrusted with strophomenid, bryozoa and pyrite. front: back: Partial Dalmanitid Trilobite in matrix When prepping, it's really wonderful how the waldron "butter" shale just crumbles apart around the predictable morphology of an enrolled trilobite. The trip just wouldn't seem complete without a short drive east to the Cincinnati Arch roadcuts. I first went to South Gate and found a flexicalymene eroding right out of the cut. It is interesting to see the comparisons here. The trilobite on the left is from St Paul (Silurian) and has beautiful pyritized eyes. The one on the right is from South Gate (Ordovician). Both trilobites have 21 articulated segments; does this make them both the same age as "adults"? Interesting to note the difference in size, being 40 million years apart, same species.. Thanks for looking!

Here is a smattering of my finds from May 2016 up until last week! Good season already! I don't own an air eraser yet so I haven't done any detail prep work on anything yet. Small enrolled Eldredgeops
