Included in multi plate alongside eight other complete or near complete T. eatoni. Found in association with T. rougensis, T. spinosus, Brachiopods, Cephalopods, and Graptolites. The Cephalon is slightly disarticulated, likely from molting.

Hello again! This post will be about some beautifully preserved Triarthrus fossils (and my first complete Trilobite finds). Some of them even have the eyes preserved! I found these at a local train station, and the site of significant construction lately. I believe most of the to be E. eotoni, and the last one to be E. rougensis or spinosus. It may not be visible in the picture, but the last one has a streak of pyrite along the side of its cephalon / upper thorax. Could this be some kind of soft body tissue preservation, similar to those of the Beecher's Trilobite bed?

Hello TFF members! I have just found several strange circular rocks on a fossil hunt a few minutes ago, which I believe to be either nodules or concretions. What should I do to split these rocks? I know that I should probably not try to break them with a hammer and chisel, and instead use the freeze-thaw process. This is my first experience with nodules or concretions, so I am not very knowledgeable on this topic. Is there a specific recommended length of time I should leave them in the cold? How long should I thaw them for? How many times should I put them through the process before seeing cracks? How cold should the environment be for the freezing to work? If they are in fact nodules or concretions, I will post pictures of my finds (or lack thereof)!

I found this fossil a few days ago at an exposure of the Billings Shale. It was found associated with Triarthrus glabellas and brachiopods. It's structure leads me to believe that it's either an Isotelus pygidium or an agnostid, although I do not know of any agnostics described in this formation and age.

Hi again! This will probably be my last ID post for a while. This time, I've decided to put all of the Unidentified fossils in one post. These are all from the Ordovician aged Billings Shale. Help identifying these will be much appreciated! 1. Leaf-shaped imprint. Mineral inclusion? 2. Trilobite fragment? 3. Dark markings and furrows. Burrows?

Hello TTF! This post will contain the pictures of my science fair board, as well as the awards I received from it. Sorry for the delay, I know that some members posted requests for these months ago, but I have been busy with other things lately. I actually left part of the board at school by accident for weeks. I hope the pictures are clear enough!

Recently, I have been out fossil hunting more often than usual, and many of them have since been damaged. Some were broken during transportation, and others were broken as I excavated them. The fossils are all from the black Billings Shale, which fractures easily. Is there any way that I can repair them without leaving any obvious markings?

Hi TFF! I have just found a very interesting fossil near my home which I suspect might be the articulated left and right pleura of a Triarthrus. I have already found other fragments of Triarthrus in the same rock outcrop. (Glabellas, pleura, cephalons, etc.) It may also be a graptolite or something similar.

Another fossil for ID! This time, I think that I have some possible orthocone nautiloids from the Billings Shale. I found these near a small construction site near my house. Although I suspect them to be cephalopods, they may also be Hylothids. Or, they could be something else entirely! I am not an expert on these faunas at the moment, so I may be wrong. Each photo is of a different specimen. Thanks in advance! More posts about the regional science fair are to follow.

Dear TFF members, As some of you may already know, I have been working on my science fair project concerning the Trilobite Pseudogygites latimarginatus for several months. This science fair project has been awarded a position in the Ottawa Regional Science Fair held at Carleton University this week. Your help has been instrumental in my success, and my appreciation cannot be expressed in words. As one way of thanking you all, I am inviting anyone on the forum who will be in or near Ottawa at the time to attend the fair. My project will be open to the public this Friday, April 6th, from 2:00 pm - 4:00 pm, and again this Saturday, April 7th, from 9:00 am - 11:30 am. It is titled, "The Impact of Environment on the Biodiversity of Pseudogygites latimarginatus." My project's number is 1101. I will also have some of my most prized fossils on display, as well as some edible specimens, for the Trilobite enthusiasts! I am not asking for anyone to go out of their way to see my project, this is just a simple invitation. Everyone is welcome.

I found this weird looking fossil on a trip to an exposure of the Billings Shale formation of Ottawa, Ontario. This formation is late Ordovician in age. It looks either circular or spiralish in shape. Does anyone know what this might be? Crinoid stem? Ammenoid? Nautiloid? Gastropoda? UFO Imprint? I really appreciate it!
