I have a few questions about trilobites. 1) Does anyone know the size of the largest trilobite ever found? 2) What is the average size of a trilobite in North America, specifically New York state? 3) What is the average size of a trilobite found in Morocco? 4) Why does it seem like trilobites are mostly found in New York state and Morocco? Do maps of what the Earth might of looked like during the Devonian period? I had a bit of a disappointing first hunting trip for these little creatures in Tully, NY yesterday and any answers that will help me better understand them will be appreciated greatly.

It seems to me that our feral horses should be considered "Native Wildlife" like any other. Why did horses in North America go extinct?

Found this today, need some help figuring out exactly what it is! Thanks guys, your opinions are greatly appreciated

Hello everyone! My name is Kirsten and I’m from WV,USA. Last summer I found my first fossilized sponge and I’ve been completely obsessed since! Definitely in the beginning stages of this hobby and I’m trying to learn as much as I can, specifically about the area I live in. I would absolutely love some help with possibly identifying some stuff I’ve found so far! excited to be in this forum!!! xo, kirsten

This tooth was found on a beach off the channel at South Padre Island. I am a shell and artifact hunter and have been finding fossils of late. I don't really know about fossils and have joined this group to help me learn and identify what I find. I have three fossils that I would love help with identification and I will post separately. Thanks so much!

Found associated with T. rougensis, T. spinosus, brachiopods, cephalopods, and graptolites. Included in multi plate alongside eight other complete or near complete T. eatoni.

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 everyone, new member here! We recently started boxing up my childhood home to ready it for a sale and I discovered a long forgotten box that had a few fossils that my grandmother obtained during her ongoing 91 years on this earth. Almost all I believe were obtained by digs she went on around North America and chances are she obtained this one in the midwest. Most had tags like fish, mammoth tusk shard, and part of a deer jaw. I couldn't find an ID for this one, and upon asking my grandmother she hasn't the faintest idea because it's been decades and her mental state is slipping. If you need any more pictures of any sides let me know, my hand is only there to hold the two halves together, because unfortunately it hasn't survived in one whole piece. It measures about 160 mm. Another clue, but she did majority of her digs in Nebraska I believe. I'll have to Split up my posts with the pictures, I apologize.

Hi all As I age, I am working on talks and the co-responding displays to donate my collections to be used while I can for talks to curious people who come to the natural history society where I volunteer. After i'm gone, having written out the talk and picture power point and with the actual fossils, these talks could go on. Also hopefully made available to teachers. Anyway, I am struggling with finding an intriguing story lines for a talk on Brachiopods and Bivalves. For example in my cephalopod talk, the story line is how they overcame the problem of buoyancy. So i am asking for your thoughts for something similar on this topic. Also ask for your recommendations for specimens to include. I'm looking for ones that grab people's attention for beauty, ugliness etc. I have id'ed: spirifers (pyritized), lamp shells, Ruck's pit Mercenaria, Cucullaea (Giant clam), Panopea, Cretaceous oyster Exogyra, Inoceramus, Spondylus, Arca hinge teeth and markings. There are some weirdly beautiful rudists from Texas (would anyone be willing to donate to the cause?) Hopefully this gives you some idea what I am trying to do-specimens that each have their own special story to catch people curiosity and interest to promote their interest in learning. And if possible, an overarching story line that unites brachiopods or unites bivalves. Appreciate everyone's thought and comments. Thanks

Hi again! I’m totally stumped with this one. The rock is limestone, so its not the Billings formation. There is still some matrix on it, but most of the surface is exposed. It’s spherical and slightly faceted. Fossil pearl?

Hello from Michigan. My name is Dan. I have loved fossils and ancient artifacts for a long time. I recently stumbled upon this forum and become instantly fond of it. Already had one indiv help me out on an ID of a fossil that I obtained. Thanks is advance to everyone in this forum :).

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?

Yesterday, I was lucky enough to attend a very special field trip with the Eastern Ontario Natural History Society to a massive road cut in Ontario. The rock exposed was Ordovician aged limestone, and it produced some amazing fossils. I might need some id help with some of these. The giant cephalopod was by far the best thing I found! 1. Giant Cephalopod (with hand for scale) Camerocerad or Endoceras? 2. Crinoid stems, bryozoans and Gastropod 3. Partial trilobite pygidia

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.
