    Repairing Fossils In Shale

    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?

    Unknown fossil

    Hi there! This spring I started collecting fossils, and I found this one in rock-glen park down in Arkona. Any ideas what it is? I'm looking for recommendations on where to go next - hungry hollow is apparently only open to groups but I've heard its a great place. Any others in the area?

    Triarthrus?

    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.

    Orthocone or Hyolithid?

    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.
  6. A friend found a few small tubs of fossils that she hadn't seen in years until she started moving stuff around last week for a possible move. She asked me if I could come over and look at what she found. Most of the specimens don't have a label but some of it is obvious to anyone who's been to shows and had friends who collect fossils as well. I don't specialize in invertebrates or plants but I know an Elrathia from Utah, a Lovenia from Australia, and a Metasequoia from British Columbia when I see them because I have a few of each myself. She has some trilobites that are out of

    Ammonite tease

    I was up in Cloudcroft on an errand and thought I might as well drive a few miles along Forest Service Road 5661, just south of the town. Here, Pennsylvanian sedimentary rocks are exposed along the cuts of the gravel road. You see a lot of pieces of fossils, but so far, anything remotely approaching whole has escaped me. Also, the rock does not seem to fracture in any kind of systematic plane, but rather at random and often right through the center of a fossil, leaving a thin section exposed and not a "half." But the stuff is there. It is frustrating. And then this thing ...

    Coral, Sponge or Bryozoan?

    I'm stumped. I've been collecting erratics off the beach along the Delaware Bay for the last six months and I keep coming up with mysteries. This specimen is 1" long. Unfortunately, because it is an erratic, all I can tell you is that rocks of this type wash down from the Appalachians all along the Delaware River and Bay til it reaches the Atlantic Ocean. They are Paleozoic, but I don't know enough of the geology from PA and NJ to narrow it down by rock type to a formation. Can't find a high enough resolution GEO Survey map, either. Other fossils in this type of rock are rugose corals, tabulat
  9. This question just crossed my mind today, seemingly without provocation: What are the oldest known coprolites in the fossil record, whether from vertebrates or invertebrates? I know of Paleozoic coprolites, but is there any evidence of coprolites before that, perhaps from the Ediacaran? And if there are no pre-Cambrian coprolites recorded, what are the oldest known from the Paleozoic? I have a feeling that @GeschWhat might know a thing or two about this subject since, after all, she is the official Queen of Poopiness on TFF.
  10. 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:

    Favosites?

    I should preface this post by saying that the Paleozoic, marine ecosystems, and invertebrates are not generally my primary expertise, so I apologize if I am wildly off base or asking stupid questions. Sadly, I did not find these specimens myself, and so I do not have any particularly useful information on age or location. They were left in a desk drawer along with a collection of other invertebrate fossils, most (if not all) of which are Paleozoic in age. They look to my untrained eye like Honeycomb Coral (Favosites sp.). Here are the pictures. Thank you in advance for your time and input

  16. This is my final post for tonight, and then I will stop cluttering up the forum. Unfortunately, this specimen has been badly weathered and so may not be identifiable at all, but the shapes are so intriguing that I can't help but ask. Any thoughts here would be very much appreciated. The two angles are from different sides of the same rock. Sadly, I did not find this specimen myself, and so I do not have any particularly useful information on age or location. It was left in a desk drawer along with a collection of other invertebrate fossils, most (if not all) of which are Paleozoic in age.

  19. This one has me pretty confused. My initial thought was that it was a nautiloid, but upon closer inspection, I realized that I did not see any sign of chambers, which made me question that ID, so maybe it's a gastropod? I'm not sure how clear this is from the photos, but the spirals are continuous (e.g., they are not stacked disks as I've seen in some nautiloids). Any thoughts here would be very much appreciated. Sadly, I did not find this specimen myself, and so I do not have any particularly useful information on age or location. It was left in a desk drawer along with a collection of o

    Trilobite Science Fair

    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-

    What on Earth?

    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? Th

    Diplocraterion?

    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.

    A Spiral Of Confusion

    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!

    Try-a-Bites!

    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
