Old finds from the Verulam formation that I "re-found"
Shamalama posted a topic in Fossil Hunting Trips
So these fossils are not from a recent trip but from two prior trips in the last year to the Verulam formation near Brechin, Ont. (middle Ordovician, Katian/Mohawkian stage). I was cleaning and sorting some boxes when I re-found them (most still in their paper wrapping). Loose Brachiopods - clockwise from top: Dalmanella testudinaria, Rafinesquina alternata, Sowerbyella sericea, Rynchotrema increbescens A hash plate with many Dalmanella testudinaria brachs among the debris Unknown Bryozoan but it was big and cool looking so I kept it. Stictoporellina sp. bryozoan The graptolite Diplograptus amplexicaulis A couple of Conularia trentonensis that Kevin @Northern Sharks found and gave me. A nice big, intact mound forming bryozoan that is either Prasopora sp. or Mesotrypa sp. A plate with a few large mound forming bryozoans that are either Prasopora sp. or Mesotrypa sp. Possibly a Sphenothallus sp. specimen? Partial Trilobite A small but nice Flexicalymene sp. specimen A Cruziana specimen that @Northern Sharks spotted and let me extract I think this is a crinoid calyx, possibly an Ectenocrinus?

I was given a treat yesterday as my wife woke me up around 6am telling me go hunt as the weather was about to drop out and end the season. I arrived to my spots around 10am as I scouted several new sites along the way. I was finding the typical cephalopod fragments and brachiopod hash plates. As I started to head back to the TARDIS I noticed a small area that had been recently exposed from a rock slide, so I figured I'd better take a look. I'm glad I did. After moving some smaller rocks I noticed a familiar shape that stuck out like a sore thumb and had to walk away and come back just to make sure I was seeing what was there. And here it is. This definitely made the trip. My first complete Wisconsin ordovician crinoid! Unidentified crinoid Mifflin mbr, Platteville formation Middle ordovician Grant County, Wisconsin

As I sit here posting my specimens for ID, the thermometer sits at 24. My fossil hunting days are soon to be put on hold. The two fossils that I posted are Ordovician found last week in SE Minnesota, NE Iowa. Both were in collapse piles so definitive strata is unknown. It would be nice to ID the trilobite so I know what to watch out for as I prep it further. The other specimen is something I come across occasionally and have always attributed it to a coral. But as I looked at this piece, the cone tips come out of the matrix, opposite to what I would expect. Now I am thinking a bryozoan? This is nothing impressive, but I love to understand what I find.

Hi I have never collected any starfish fossil so I do not know what to look for in a fabricated specimen. So here is a pic of a specimen I'd like to get but I am unsure if this specimen had any restoration done to it. To me it looks quite ok. Do you guys agree? Any comments are welcome.

Howdy All Nov. 4, 5, 6 2016 Any who would like to hunt fossils in Southeast Minnesota are welcome to come meet at my place - Whispering Winds, 505 W. Park St., Spring Valley, MN. Spring Valley is 10 miles north of the Iowa line on Hwy. 63/16. Raggedy Man (trilobite hunter) is coming from Wisconsin and the more the merrier! We've had two torrential downfalls with major flooding in the last 30 days, so lots of fresh fossils out there. Go to my fossil blog (link below) and take a look at the category "Fillmore County Hunts". A map of Spring Valley which pinpoints my place is in the Educational Tours tab on the bar. Weather forecast is for highs in the 60s and lows in the 40s with SUNSHINE! We've had two hard frosts so the bugs and snakes are down and so are many of the weeds! FREE CAMPING! Parking in the pasture. My upstairs is currently empty but suited for guests with a queen size memory foam bed - first come first serve. :-D I have fossil hunting maps for Fillmore County and Winona County in my fossil barn. I have fossil prep areas in that barn open to TFF members. This is FREE, FUN, Fossil Hunting!!!

I recently was able to stop at the well known ordovician roadcut just north of St Leon in Indiana. What a wonder. I was able to be there only an hour, but it was fascinating. I was able to find these nice brachipods, but would like to label them correctly and so far books haven't helped me...I thought perhaps someone would be familiar with the brachiapods from that road cut and help me out. thanks. the people on this site are always helpful, and knowledgeable and so it is exciting to be a part of it all. The Brachiapod labeled 6, a,b,c are obviously three different views of the little guy. the coin for size in the edge of the photos is a dime. This brachiapod is so cool, one can see the opening edge between the two halves..so cool.

Distorted Trilobite from South Hero Island, Lake Champlain, Vermont

Flexicalymene sp. (distorted specimen) Ordovician South Hero Island Lake Champlain, Vermont -
For some strange reason the term 'small flake of bone' sticks in my mind as the likely evidence to be found of early fish. It came to mind when I noticed this shape under the loupe. My dating of Ordovician is based on the fact that I find the cross sectional shapes of Prismostylus in other of the distinctive rocks. I'm fairly sure they are actually crumbs that rolled of onto the lake shore during construction of a rail bed. It's so small I had a hard time getting a clear shot of it, but do you think there is a chance ?

Got out yesterday to some exposures of shale in Southwestern Ohio. Found a couple nice trilobites; Isotelus and Flexicalymene. A couple nice Isotelus pygidium. I got heavy into some pelecypods and a couple nice brachiopods were laying in the stream, one with a nice bryozoan on top.

In the driftless areas of Minnesota, Iowa, and Wisconsin I find many Orthocone Cephalopods. Each one seems to have its unique way of being preserved, some as an outer shell, others with their internal anatomy showing. A few weeks ago Raggedy Man posted a cephalopod that looked to be a siphuncle to me. Bev on the otherhand thought it was a phragmocone. No experts chimed in so a conclusion was not determined. That following weekend, I did a little collecting in Iowa. The trip was highlighted with the finding of many cephalopods. As I cleaned the findings, my mind went back to Raggedy Man's post. The more I looked at these collections, the more I wanted to understand the anatomy exposed. I think my biggest frustrations are telling siphuncles from phragmocones. Are siphuncles always smooth surfaced? Should septa be seen in any unworn phragmacone? How does one differentiate phragmacone from the external surface of a cephalopod? Finally does anyone have a good site that ID's our local Ordovician cephalopods? Thanks for any input!!!!! Now enjoy my finds. By the way, since it IS football season, I HAD to use a BUCKEYE to size my cephalopods. If anyone is unfamiliar with a buckeye, it is a little bigger than an acorn. For any of you buckeyes, OH......

A couple weeks back I took a trip to SE Mn to search for the rest of a Brachyaspsis sp. trilobite I found back in July. I new my quest was difficult and almost an impossible one, but I took a chance. I had made plans with @fossilized6s to meet up with @Bev and @papadave for his first Mn hunt. His goal as was mine, was to hunt for and find trilobites. Even if I didn't find the rest of my trilobite, I would still be in good company. I arrived Friday(a day before fossilized6s) around 9am and headed straight for my site. After locating the spot I found my piece back in July, I mapped out a grid in the area I thought would cover the best ground. It became apparent after several hours under the hot sun that my attempt was futile so I stopped and just walked around looking for other traces of trilobites. About an hour later, I started walking back up to gather my tools and take down my grid. As I approached the boarder of my grid, I looked down and a shape in a rock triggered excitement. There it was!!!! However, it wasn't the piece I was hoping for. The piece that I thought might be whole was in fact 2 or 3. I took a picture and ran back to the TARDIS..err truck, and fit the piece on. The piece fit absolutely perfect with no gaps or damage. I marked the spot it was found for future attempts. The photos of the site contain information that could expose its location so they will not be published in this report. The first photo is of the piece I found on Friday. The next 2 photos are of the piece I found in July. The last photo is of the two fitted together.This piece gives me the left eye, thoracic segments and the rest of the left cheek. Oh, and in case if anyone is wondering...Yes you can bet Ill be back later this year for the rest! Measurements are in CM Brachyaspsis sp. Elgen Member-Maquoketo Formation Upper Ordovician SE Minnesota

Hi! We were at Craigleith, Ontario (Ordovician, lower Whitby formation) today for a toddler's fossil hunt birthday party, and found this neat assemblage of brachiopods, bivalves, and (I am guessing) trilobite bits. At least, they look trilobite to me, but I was hoping someone would be able to explain them. Are they curled up? Could they be part of the larval stage? Something else entirely? I didn't get a scale shot but by my memory I'd say the bits I am trying to figure out are <5mm across each. Thanks! Gavy

Another one to identify, Crinoids appear to be a little difficult to identify but this has a fairly complete head. I am looking for opinions on authenticity as well. Looking at the progression of crinoid evolution this looks similar to some from Ordovician to the Permian.

Ordovician SE Minnesota Galena Formation I have confirmation that the bottom one is a worn Isotelus pygidium, but don't have a clue on the upper one. And maybe you want to look at some of these and see what you think since I have the room... :-) I'm thinking possible trilo parts. Perhaps a buried trilo? Oh well, might as well continue... -)
