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.

Happy March break TTF! I hope you all had a fantastic holiday! I have just gotten back from a fantastic trip to Florida. Thanks to TTF, I was lucky to discover the peace river. This discovery caused an entire re-write of my family's vacation plans. My father, who was also looking forward to walking through a swamp, agreed to join me on an expedition there. This was my first fossil hunting trip in Florida. I would also like to give my thanks and free advertising to Fossil Funatics, the tour operator who organized the hunt and provided the resources for us. We had a very successful two days. The guy is truly helpful, knowledgable, and fun to be around. He kindly gave all of his Dugong ribs and some of his shark teeth to me. We actually went to a stream which feeds into the actual peace river. As soon as we arrived there, I found myself overtaken by a sudden obsession with Dugong bones, earning my the titular nickname given to me by my dad. Since I have literally hundreds fossils from the river, this post will be dedicated to the Dugong bones. More posts on this are to follow! Enjoy!

Attention TFF members! I'm posting this to bring you an extremely important announcement! (For Me) For the past few months, I have been posting topics regarding Ottawa fossils and the Trilobite Pseudogygites latimarginatus. I have been doing this for research and information for my grade 8 science fair project. This experiment involved the relationship between Ordovician sedimentation and the average lengths of Pseudogygites latimarginatus. The title was, "The impact of Environment on the Biodiversity of Pseudogygites latimarginatus." Though, other possible titles included, "Another one Trilo-Bites the Dust," "Trilo-Bite Sized Science," "Don't Trilo-Bite the Hand that Feeds You," and "Trilo-Bite Me!" Last week, I fully assembled the presentation board and all other related displays. I presented my project to three judges (including professors and students from Carleton University) in addition to many other people who passed by. The following day, my school held an assembly which would announce the top 5 winners of the grade 8 science fair. After much delay and suspense on my part, it was announced that I had won first place in my grade! This means that I will get the opportunity to compete in the Ontario regional science fair this April! It turns out that one of the reasons why I won first place was because the teachers who were doing research on my project's nature (name pronunciation) stumbled upon my many posts on this website! I will continue to make posts on the forum. I think that I should give acknowledgement to all the TFF members who helped me achieve my goal, or contributed in any way! This includes all the people who helped identify my mystery fossils and gave fossil hunting advice and locations during these past few months. These are in no particular order. Thank you all!

Hi TTF! Since I am now going to present my science fair at the Ontario regionals, I have decided to add a few new displays to it. Right now, I am working on a model of the Earth during the middle Ordovician, when Pseudogygites Lantimarginatus lived. I have searched the internet for pictures of the middle Ordovician Earth, but each one is slightly different. For example, the location a Siberia changes with almost every map. I assume this is just because the different maps were made during different eras or by different people. Does anyone on the forum know which is the most up to date image? There are some images of the globe as it is right now below.

Hi again! I have another unidentified fossil from the Billings. It is a brown or dark yellow coloured streak. I think it must be some type of ichnofossil. To me, it reminds me of some fossils of Diplocraterion. It could also just be a streak made from another mineral, such as calcite. It is preserved alongside one almost full-length crinoid stem impression and one 3 dimensionally preserved specimen of the aforementioned animal.

Ok, let me explain this title. I was out for my second hunt in the Billings Formation yesterday and found this fossil. There have been many fossils that I could'nt exactly identify, but usually I have some inclination or hypothesis about its identity. This is not the case here. I am at a total and complete loss as to what this thing could possibly be. It is circular and ribbed. The first thing I thought when I saw this was "human fingerprint". I have put my own finger in the picture for scale. Looks like somebody stepped off the path in the Ordovician!

Another unidentified fossil from the Billings Shale Formation! This time, it's some kind of spiral shaped fossil. There are actually three in this one stone, and many more in other places, so they are fairly common. This fossil has a definite spiral shape, unlike the orthocone cross sections. Right now I think they are either some type of Gastropod, or a coiled ammonoid nautiloid cephalopod. Any ideas? I appreciate your help!

OK, I think I am kind of bending the rules on what constitutes paleo reconstuctions here. For the past few months I have been doing work and research for a Trilobite (Pseudogygites Lantimarginatus) themed science fair project for school. Now that it is February, the actual presentation of the project is approaching quickly. Since I enjoy baking and arts and crafts, and because I am a firm believer in the effectiveness of bribery, I wanted to incorporate something extra into my project. After hours of scouring the internet for all things Trilobite, I found a template for these Trilobite shaped cookies. After one night of hard work and over fourteen nights of doing nothing, the cookies are finally finished! Enjoy! (The pictures)

Looking to for an identification of this brachiopod. I bought it from a collector selling his collection 35 years ago. Unfornately I can't narrow the location more than the southwestern United States. Time period: Phanerozic, probably Paleozoic.

Greetings again TTF! The Billings formation is just filled with stuff that I can't identify! This time, I have found some glossy, cylinder-shaped things in the Billings Shale. I know that conodont elements are known from some parts Ontario and Quebec, but I think that it might be a belemnite as well. They seen to be associated with crinoid stems, brachiopods, and one Pseudogygites Lantimarginatus pygidium. They are each roughly one centimetre long. They are in the centre of the first picture and the second picture.

It's a UTF! I found this in an exposure of the Ordovician aged Billings Shale Formation. It's clear that it is a Trilobite fixigena, but I was wondering if a Trilobite genus can be identified from one alone? I have found three distinct forms of Trilobite in this formation: Pseudogygites pygidiums, Isotelus fragments, and Triarthrus head pieces. Any ideas? Thank you very much!

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!
