As I went through the rocks I had collected in October from the Ordovician's Galena, likely Stewartville Formation, a SMALL gastropod popped out of a piece of matrix that was split open. After looking thorough my references, I could not place this fossil. Hence the need of your help.

I have found a few of these mis identified fossils from the Galena/ Ordovician. A request for identification was made awhile back and I labeled them Asgadaspira evolvens based on a response given to me. Having just exposed another one, I searched for it on line and nothing came up. Did I misspell it or am I just out in left field? By the way the first one measures 8cm by 5cm.

Found what I think looks like a trilobite cephalon in a creekbed, but I'm not certain. It was fragmented, and the shell looks to be eroded away. This creek had a slurry of Mississippian aged Burlington Formation and assumed Ordovician aged Trenton Limestone mixed throughout. I found Mississippian crinoids and Ordovician cephalopods at this location. It looks like it resembles Illaenus taurus, or some other member of the Illaenidae. Any opinions?

From the album: Credit River Fossils from Streetsville, Ontario (Georgian Bay Formation, Upper Member)
Favistina calicina coral from the Credit River near Streetsville, Mississauga. Georgian Bay Formation, Streetsville Member, late Ordovician. Found as a loose specimen by the banks of the Credit River. This colonial rugose coral is very abundant along the site with many small loose colonies. Some colonies can be found on a limestone matrix. Please click on image sizes to see details of the corallites. -

On a trip to southern Indiana yesterday I met a member of the fourm, Newbie_1971, and he helped me find my first trilobite! I found several well preserved gastropods as well as some pieces of isotelus trilobites.

Greetings from Oberwil, Switzerland. I'm a new member on thefossilforum.com, but I've been collecting fossils from roadside stops and occasional dedicated outings for nearly 30 years. I'm a chemist by training - I fell in love with making new medicines, and have stuck with it. I find it mind-boggling to relate to the age of the fossils I'm holding...life is far more ancient, far more mysterious, far more marvellous than our imagination can comprehend. I've learned to respect life deeply...this planet is the only one where we know it exists, and has existed, for unimaginably long time. I'm in awe. I'll share some pictures from my collection in the coming days, in hopes of finding out more about where they fit into the grand scheme of life. My favorite fossils are Ordovician (Paleozoic), but I've come across some real stumpers from my trip to Madagascar a few years back; those fossils are almost certainly from the late Mesozoic. I'll be asking for advice on them soon. Ah...I'm now a Swiss citizen, but I was born to German (Swabian) parents who had emigrated to southeastern Tennessee in the early 1960's. Switzerland is home to me now. Best regards Mike

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.

Hi everyone! I was in SE Minnesota recently, looking through limestone outcrops where I have found cephalopods on a previous trip to Mystery Caves, MN. While looking for more cephalopods during my most recent trip to Fillmore County (and finding a few) I found this piece shown below. The fossil is likely Ordovician aged, as is common in SE Minnesota. The formation I am less sure about, but if I had to make a good scientific guess, it is the Galena formation. My question is if this is a cephalopod fossil that is just heavily eroded, of is this just a cool rock? I decided to also flip the fossil with my hand to better see the ends. Thanks for the help everyone.

I have a nice little slab of Platteville Formation (Mifflin Member) from the Ordovician of SW Wisconsin that I received from @connorp late last year. I am working on a post that describes all of the great things in it, but want to get a couple of ID's cleared up so I can be more concise in that post. Here are three trilobite pieces found on the slab that I have taken a stab at an ID, but would love confirmation/correction. Hopefully there is enough there for some of our trilobite experts such as @piranha , @Kane or any others to offer some advice. Thanks for any insights anyone can offer. Each picture is numbered in the upper left. Mike Here is a picture of the small slab with the location of the trilobites in question numbered. The sharp eyed will see another trilobite cephalon in the lower portion of the slab. I am fairly certain that one is Gabriceraurus mifflinensis. Here is the first question. This looks like the best match I can find for species listed from that formation, but I'm not certain. I wish I could get this one a bit cleaner, but the matrix left is pretty hard and stuck to the pygidium. This one may be a stretch as there is not much there, but maybe enough to be recognizable (or maybe not). Thanks for any help.

Over a week ago I took advantage of our university's Reading Week break to hop a train east to do some late season digging. Apart from a few surprise finds, it did not quite live up to my expectations. I had to hastily organize it as I had got the dates wrong, assuming Reading Week was the following week (one of my students corrected me). It meant getting the trains and motel all lined up with barely a day to spare. Upon my arrival in Toronto for a layover, someone not all together upstairs thought it would be a wise idea to pick a fight with me. I defused the situation, but it certainly help set the tone for this week-long adventure. On the first day of the dig, I ended up walking about 25km for nothing. On the next day I went back to the spot that had been so productive weeks before, but this time it turned out to be the opposite with two exceptions. Unlike last time when cheirurids were popping out like they were going out of style, not even more than a pygidial spine of one this time. Instead, a pair of crappy Flexis:

I was storing more of my collection away the other day, when I saw the eye of my Colpocoryphe specimen. Eye lenses! My other specimen has them too, but the eyes are a bit crushed. I thought it would be nice to share. I never saw these, and the second one was the first ever trilobite I got. I can’t believe I never noticed them.

Hi all! I am back again (this time in Montréal and found a peculiar looking fossil. It is very circular, almost has a subtle stippling on the top surface (which leads to think maybe a sort of precursor coral/bryozoan). It popped out very cleanly from the rocks we were excavating. The other fossil for ID is the brachiopod in the 4th and 5th pictures: Topside Underside Side Profile (its rather thin, but thickest in the middle - somewhat dish-like) Measurements Brachiopod for ID Thanks in advance! -Em
