I went to St Leon Indiana, and I had a pretty good haul!!! Spent the day out there I have several fossils that are from the Ordovician time period and they’re in limestone, limestone shale. Does anyone have any good tips on washing them? Do you prefer dry? Just with a brush? What about any rusted stuff, do you use oxalic oxide? What about algae? Do you prefer water? Soap and water? Hydrogen peroxide? I’m afraid and don’t want to ruin any. Thank you! Jessica

I found this in St. Leon, IN, Waynesville formation, and was just wondering if it was an orthocone fragment or something else. Thanks!

My wife and I spotted the large rock below yesterday along the shore of Lake Champlain in Shelburne, Vermont, and were intrigued by the light colored branching patterns. The rocks here are Ordivician in age. We're not sure whether these are fossils or not, but hopefully someone here can help. The pattern is flat/flush against the surface of the rock. Thanks in advance for your input!

My wife and I are up in Northern Vermont for the Thanksgiving holiday and were able to take advantage of a beautiful day yesterday by going for a walk in some woods and fields along Lake Champlain. While exploring the shoreline, we came across this rock wall and my wife spotted what looked like a fossil shell. Lo-and-behold, the wall was full of fossils--primarily gastropods I believe. We're not sure where these rocks came from, but the rocks along the lake are Ordivician in age and there's a good chance these came from a similarly-aged rock quarry in the

When was the Great Ordovician Biodiversification Event? (GOBE)?
Daniel Fischer posted a topic in Questions & Answers
Hello, I have a question about the great ordivician biodiversification events (GOBE). I know this series of events happened between the late cambrian and the late ordivician but are there more specific dates for it? For example like the great dying was about 250 million years ago. I couldn't find anything more specific then late cambrian to late ordivician but if you know something more specific or you know that there isn't a more specific date please tell me, I would love to know! -
Please advise what type of animal is this: it could be a trilobite, brachiopod or plant-animal. N.2 N.3 N.4 - this is most likely a small trilobite ( 1 cm) N.5 N.6 N.7 -left side segment N.8 - here I put some oil on this segment for better visibility

Gorgeous Orthoconic Nautiloids (Toronto/Ordovician-Georgian bay formation))
Emthegem posted a topic in Fossil Hunting Trips
Hello to all! Its been a very long time since I've been on here, but my recent trips around the creeks in Toronto, Canada (in the Etobicoke area) have yielded some of my largest and most defined finds of all time, here are some of the nicest Orthoconic Nautiloids I had found yet: Probably the nicest one in my collection at this moment, found almost completely by fluke when I hit a rock with my pick and this bad boy showed up Imprint made by the previous one These last couple would be way nicer, if only I could find a way to get it out of t- 15 replies

Another decent haul over the last few days. Bunch of nautiloids and whatnot, a couple mussels. These were my favourites from the last 2 days in the river. This was a biiiiig nautiloid, and after cleaning it I realized there were two of them! wowowowo! (Sorry the picture didn't turn out quite that nice) This is probably one of my highest quality specimen so far, although it did break near the end when extracting it from the matrix.

Hello, I recently cracked open a rock to find one the most pristine and unusually shaped fossils I've seen in a looong time. I predict it might be the edge of a bivalve shell poking out, but I wanted to know what others might have to say about this. It was found in the rock deposits of the rivers in Toronto, Canada, and is part of the Georgian bay formation. Also, only the bottom half seems to be completely crystallized and is translucent, whereas the top is relatively opaque: I am somewhat worried about totally ruining the fossil if I try to further crack

Hello, I d like to know if someone would trade unpreped crab nodules. I mostly have french trilobites to trade. Some echinoid also . Some albian minicrabs carapaces. I post those 2 first. Ill post more later . The roller is Colpocoryphe rouaulti, the other one is a small Ectillaenus giganteus. Regards

I have spent a really long time looking for this fossils name, I know it's from the Ordivician period I just don't even know where to begin to classify it. Pls help!

Back in April 2017 I posted pics of what I thought was a unique bryozoan encrusted horn coral.... Since then I have come across more while collecting in SW Ohio that I'd like to share. And, yes, the prep can be extensive. The first one, there is no real top/bottom or side view. It is 7 cm across x 10 cm "tall" This one is 4.5 cm across x 4.5 cm "tall". I believe the bryozoan on the following is Constellaria florida This one is 5.5 cm across and 6 cm "tall" This last one is my favorite. I finished prepping it in early March

If you are a fossil collector in an Ordivician area, the Rafinesquina is a pretty common find. Here are pics of some typical pieces from my collection. The R. ponderosa (middle) are typically 4 to 5 cms wide. Below is the view of them from the side, showing their basic difference in appearance. Late last summer I came across 3 brachiopods on a maybe 30 degree roadcut south of Dayton, OH that are similar to the Rafinesquina. All three were within 2 feet of each other and broken "from the middle out" as if they had been stepped on...or maybe run ov

I haven't seen hardly any Ordivician-related posts for a while so here's my input. I was out collecting yesterday off Interstate 75. Nothing all that good had occurred until I found this flexy... Nearly 5 years ago I found the chunk of rock (in the middle of my hand) that appeared to contain some amount of trilobite I never expected much so it was ignored until this past Feb when I finally prepped it. I was happily surprised at what finally appeared. It has a few blemishes and is nearly 100% complete.

I found this plate near in the upper decorah formation Minnesota (Ordovician period limestone). These chunks are frequently littered with trilobite bits and fragments but this lookk a little odd to me. It has a "knob" or bump structur on one side and a gradual bend on the other. Its still partially covered by coral and debris but most of it is exposed. Any ideas?

Hello! I found this odd looking fossil the other day on a river bank in Toronto after splitting the shale. It seems to be possibly be a coal imprint of some sort. Not too sure what it might be. Let me know what you guys think: Thanks for the help!! -Em

Here's a specimen I picked up last year from the St. Leon, Indiana, road cut. The site is late Ordovician in the Waynesville formation. My guess is that it's a trace fossil that shows the convex hyporelief of two trilobite burrows. Each borrow is approximately 4 mm long, and is 2 mm of the other edge of one burrow to the outer edge of the other. In the second image, you'll also see what I believe could be pygidium or cephalon impressions on the left side, about two thirds down.

Hi all! I managed to go on 3 large fossil hunting trips this weekend and pulled in easily the BIGGEST haul so far with the most variety as well! The first two pictures were from Mimico creek and the rest were a mix of Humber river and a separate section of Mimico creek. I managed to pull in my second trilobite from the area so that was very exciting! Also pulled a bunch of stuff that I was not able to identify: /\ This was the haul from last Friday night /\ This is the trilobite I found!!! Very excited to have a second one - its been a while since the

Location: Etobicoke creek, Toronto, CA Date collected: July 27th, 2019 Hello! I pulled in a whole bunch of fossils along the Etobicoke creek (a little bit further north compared to my last trip - almost same location though). LOTS of Orthoconic Nautiloids (as usual), a couple different bivalves and a few crinoid fragments. This is the nautiloid haul. The top right one doesn't look like much but there are about 5 or 6 nautiloids embedded in the matrix! I'm considering learning how to clean up the fossils so that I can show it off in all its glory!

In a recent trip to the Candelaria Mining district of west central Nevada some rocks that suggest fossil forms where found. Is this a fossil? How big where coiled Nautiloids in the Ordivician? Is this more likely Permo-Triassic? I have more pics but the file size limit. Maybe another post later.

Alrighty. Havent been around much as I havent been doing a lot of fossil stuff of late. But, I was going through stuff I piled up on the porch from my KY/OH trip last year and came across this. I honestly dont remember finding it. You would think I would as it is only the second trilobite anything from that trip. Its not marked from OH, so I am presuming I got in KY. What particular bug would this be?

I've had this for several years but just got around to prepping it. I believe I've seen similar on the site in the past few years but don't remember what it is.
