Hi all Never thought i would happen to say that, but this week end i put a final effort into cleaning trilos i picked during winter season and i have to admit it : I'm overwhelmed with trilos. Some of the visits had been the most productive i made and even if you dont come home with the quantity, there's always something to make the trip worth. Most of the best pieces had already made it to the shelves, i posted some in earlier topics. So a big part of what i finished are B grade samples. Some have their head more or less disarticulated, some the pygidium missing or damaged. So heres the group view of what i more or less finished over the past two weekends. I ll keep posting in this thread, the most noticable stuff once i got the pictures sorted, so stay tuned.

Greetings! I was totally captivated by this and snapped it up at our Gem Society Auction, a donation , and I have no information on it. Appears to be in a slab of shale? Imprint is about 3" long (pen next to it in photo 1 to show width of slab) Photo 3 is the backside of it. Any help appreciated - especially just to know if I was an implusive idiot to bid on this!

Hey everyone, New member here, my husband and I just got started fossil hunting on the shores of Lake Ontario near Courtice Ontario and found lots of these trilobite looking things in between shake layers but we are having a really hard time figuring out what exactly it is. Any help would be greatly appreciated. Thanks in advance!

Hi all, I've been searching the internet pretty thoroughly the last few weeks, checking everywhere multiple times a day to find a low-quality keichousaurus to practice prepping on, (knowing that 95% of specimens are fabricated or heavily restored) and I think I may have found one. The price is so reasonable that I really don't care whether or not it's partially fake or restored, as it will make a decent display or even a gift if it turns out to be 100% fabricated. So I suppose I'm wondering how much of this specimen looks fabricated, and if it would even be possible to attempt an air abrasive or acid prep for this guy? How rare is it to fabricate or even partially restore a keichousaurus that's still mostly covered in shale?

My first fossil and I'm already stumped - hoping someone can point me in the right direction here! My husband is a geologist and brought a piece of shale home with a fossil poking out. I've been chipping away inexpertly, and can't figure out what I'm looking at. This was found outside Birmingham Alabama, in the Mary Lee Formation, near the Pratt Seam. My husband tells me the area was freshwater swamp during the Pennsylvanian Period. What am I looking at here? I know it shouldn't be soft tissue, but it doesn't seem to be plant, shell, or bone, either! Please set me straight! I hope these pictures are ok - as you can see, I'm not done cleaning it... but I'm trying to be cautious since I'm learning as I go. Also possibly relevant: the shale was riddled with dark colored fossil plants. My husband said they were carbon - they nearly disintegrate on contact. I've included a picture of those, too. Here are pictures of the plant fossils in the rock that were exposed when we broke it apart. The mystery fossil is on the top of the left rock. Thank you all!

Edited : back then i wrongly ided the specimen. Not a Neseuretus, rather a colpocoryphe. That's always happening to me when processing older stuff... Hi all, Now and then we read topics about trilobites molting. While processing my trilos and entering them to my database, i noticed i never posted this one on TFF (or anywhere by the way). Some might find this one interesting (i do). So, here it is :Colpocoryphe rouaulti 's molting : you can see it got 2 bodies, the main one (old one) on the right and the new one attached to the head part.

Just beforehand my exit on the highway, I really needed to use the restroom, and pulled off at a rest area. This was quite lucky, since there was a very large piece of shale sitting in front. The whole thing was a giant hash plate. It was heavily weathered though and there were a bunch of fragments strewn around. I ended up finding quite a few nice pieces in the debris on the ground. Here's the rock and a closeup.

The cabin fever I’ve had the last couple months finally drove me mad. Inspired by the posts of @KimTexan, @FranzBernhard, @Al Tahan, and @Calico Jack. I decided to brave the snow and cold and attempt a new place that I had been contemplating visiting for several months now. This was not the easiest time to be hunting and probably not the safest thing to do as I haven’t seen a lot of the fossils in the formation, the entire outcrop may be under a foot of snow, and adding snow to any fossil trip is inherently more dangerous. But I tried to insure the highest chance of success and safety and I will now share my experience with this. I don’t claim to be a professional and I don’t claim this is safe, if you attempt to hike and hunt fossils in the snow you do so at your own risk. Since, I didn’t know what exactly the fossils looked like, I had only glimpsed at a couple specimens in a couple local museums. I took to the internet for any pictures I could find. I found this thread This website http://www.ammonoid.com/Manning.html This paper https://emp.byui.edu/STRICKLAND/fossil.pdf And various examples for sale that I won’t link here. I just basically looked at anything and everything from the formation to get a sense of what the fossils looked like. To make sure I was going to the right location I looked at geologic maps via the apps I have listed here I looked land ownership maps like this one https://platmap.trustlands.utah.gov/ and this one https://blm-egis.maps.arcgis.com/apps/webappviewer/index.html?id=6f0da4c7931440a8a80bfe20eddd7550 And a couple other more site specific maps to double check. I also looked at a topographic map of the area with geologic maps overlaid https://geology.utah.gov/apps/intgeomap/index.html# Sattelite images from https://www.google.com/earth/ and roadmaps like this one https://www.google.com/maps I knew I may not have cellular reception so I brought a Garmin eTrex GPS as my field instrument along with extra batteries. I also brought a rugged Brunton compass in case my batteries all died. Some tips: Research how the area generally is during winter. Look up depths of snow in the area if available, any road closures, if available, where snow plows will plow in the event of a snow storm, take a look at the weather forecast, look up roads or trails you will use as escape routes during snow storms, etc. Having camped in the snow and have done a decent amount of winter sports like ice fishing, I know how to dress warm. Remember more layers is better. It’s better to have to remove layers than add some because you may not have any extra clothes to add. On the other hand, try not to break a sweat as that sweat will cool you down very quickly and may put you at risk of hypothermia. Make sure to bring And ALWAYS notify someone where you are going, when you are going, how long you will probably be, what you will be doing there, and if needed how you are getting there.

How’s everybody doing? I’ve got some fossils I need ID’d. They are from the Manning Canyon Shale in Utah. They are Late Mississippian/Early Pennsylvanian in age. Thanks!

I made another day at my favorite hunting site. A cold and wet day. Didnt score anything really noticable, but this fat boy : Ectillaenus giganteus, who is actually "giganteus", complete and not that streched !
