  1. A short post today, just wanted to upload this interesting Rhizocorallium (?) I found on my most recent fossil hunting trip! It’s still the dead of winter here in Saskatoon, but we had a warm snap recently and I was able to hike out to a local glacial silt exposure and found it. Hoping to return to this site soon and hopefully find more!
  2. Another day of great finds in Saskatoon! This time, some trace fossils. With my wonderful collaboration with the University of Saskatchewan's Museum of Natural Sciences still continuing, recently I have been very lucky to make multiple trips out to a beautiful site just outside the city of Saskatoon where massive deposits of glacial lake silt are exposed. This silt produces pristine grass and other plant fossils in abundance (I'd like to make a post about them soon as well), but also seems to be teeming with various invertebrate trace fossils. All are very small (under 1 centimetre wide). I've attached some of my best pictures below. 1 - 6: Overlapping Planolites sp. closeups 7 - 11: Edaphichnium sp. 12 - 14: Taenidium sp. closeups 15 - 16: Taenidium sp. wide shots 17: Taenidium sp. closeup

    New here! What have I found?

    I found a few different rocks and I'm curious what I have here.. one is a cluster of shell and even has like whole ones inside the rock.. and the other I believe is a ammolite.. I was in southeastern saskatchewan at a rock Pitt where I dig into the ground with a loader and I found these rocks!
  4. Hi all. I don't really know anything about fossils. I have always been fascinated by them, but have no real knowledge. I found this in a lake in Central Saskatchewan. Someone on Reddit suggested it's a vertebra. How do I go about identifying which animal it may have come from? It's 5x7 cm

    Caddisfly Larva?

    Hi again everyone! I have a small fossil from a unit of lacustrine laminated silt from here in Saskatoon from the very late Pleistocene or early Holocene. The unit directly overlays a unit of till from the Wisconsinan glaciation. The unit contains carbonized plants stems, some of which are filled with wood boring beetle larva frass, diatoms, and burrows similar to Cruziana. In one of these hollowed-out burrows, I found this fossil, which is approximately 0.5 mm in length. It is composed of many extremely small carbonized plant fragments, all arranged horizontally from longest to shortest. I have no suggestions to explain how such an arrangement could occur through abiotic means, and the fossil bears a striking resemblance to caddisfly larva cases, many of which are composed of plant fragment arranged horizontally. I have attached some photos taken through a microscope lens on an iPhone. In hopes of accounting for the rough image quality, I have included numerous angles and degrees of brightness to help illuminate the arrangement of plant fragments. Any help confirming the caddisfly diagnosis or directing me from my incorrect guess to a correct one would be greatly appreciated!
  7. Hi! I’m still trying to identify one fossil from a particular unit of Pleistocene/Early Holocene lacustrine silt from my hometown of Saskatoon, but I figured I would look away from it for a bit to try and identify another fossil from the same unit I’ve been unable to classify. I have two specimens, both apparently of the same species. They are both approximately 0.5 millimetres across. They are perfectly circular, with lines radiating from the centre and rings of alternating colours (possibly representing growth lines). One specimen is photographed dorsally, showing its circular shape, the other in profile, showing its umbrella-like, protruding outline. All photos are taken through a microscope with my best camera currently available, an iPhone! My main areas of middling expertise are arthropod and vertebrate fossils, so I have no idea what this is! I have briefly studied fossil foraminifera and diatoms in the past, but it looks like nothing I’ve seen in those areas as well. It reminded me of a small limpet, some type of seed or spore, or perhaps even a strange fish scale, but I have no formal suggestions. I’d highly appreciate any help! I will try to supply any additional information you may need. Thank you!

    Marine Reptile?

    I found this fossil in a rock pile the other day. I have not tried to clean up this specimen aside from a quick rinse under running water. I’m new to fossil hunting (and this forum) but am curious as to what this might be? Looks like it’s possibly the lower jaw of a small marine reptile. It was found in West-central Saskatchewan. Thank you in advance for any replies!
  9. Hello! Thank you all for taking the time to read this and (hopefully!) help me identify a very interesting find from Saskatoon! I was on a fossil hunting trip to a local exposure of Pleistocene glacial lake sediments in Saskatoon, and I took home a few samples of it to review later. While looking through one piece (the material is silt but breaks like a rock and is somewhat laminated), I saw this very strange shape. Attached are a few images, some simply in situ, others through a microscope. My apologies if the image quality is not ideal, I do not currently have any better equipment. There are a few images with my fingernail in frame to give you a sense of scale; this thing is very small. It is a kind of dome shape adorned with concentric rings of linked “nodes.” When looking at it, I knew it couldn’t be a pebble or partially buried rock. The thing it reminded me the most of was a Ptychodus tooth or other fish tooth plate, but the “dome” the nodes sit upon is penetrated open in one spot and is hollow. While I suppose this doesn’t rule tooth out, it does make me doubt that possibility. In addition, the nodes appear to resemble fish scales, especially ganoid scales, as some are rhomboidal in shape and all have the glassy coating those scales tend to have. There is also what appears to be a bone fragment near the dome. This is where my own suggestions end, I have no other ideas as to what this weird thing might be! Simple confirmation of the nodes as fish scales would probably satisfy me, but identification of them as ganoid would be even better. Please let me know if I can provide any extra clarification! Thank you!
  10. My eagle-eyed mother found this in Saskatchewan Canada over 40 years ago...No idea if it was a shell, plant or a cocoon...if something new or very ancient, but all searches thus far have not helped me identify it.

    saskatchwean corals? 2/3

    2/3 found these on shore of Lake Diefenbaker in Saskatchewan, Canada. looked to be eroded from sandy deposits with layers of harder iron-rich rusty strata. the fossils themselves are heavy, mineralized with iron and then rusted? corals? all the same type or different? i think this is in cretaceous age but not sure. see other 2 posts these specimens are larger, very heavy. like solid iron, looks like outer textured surface mineralized and inner cavity separate - looks like central tubular structure did not mineralized (still sandy) in one pic (could scrape out with toothpick)

  14. So I decided that I would finally make a point of documenting some of these back country field excursions, and made a Youtube channel to keep the videos all in one place. Here's a a rather ordinary extraction of a placenticeras ammonite found the day before we did a little field work with some paleontologists. The GoPro is a fun addition to my kit, and makes it a lot easier to document the actual process of finding and extracting these things in the field. Anyway, I'll let the video speak for itself - enjoy! (click the image to open video link)
  15. Hello all, I recently found this strange fossil within a sandstone concretion from the late Campanian marine Bearpaw formation. I'm very familiar with the typical ammonites and other molluscs of the formation, and haven't seen anything like this - is it some sort of nautiloid, or something else entirely? Thanks.
  16. Hello everyone, A few weeks ago I came across this fossil in the field, and couldn't make ends of what it could be. The locality that it was found in represents a shallow marine lagoon environment, deposited in the late Campanian marine Bearpaw formation of SK. Typical finds at that locality (all within sandstone concretions) include nacreous mollusks, as well marine vertebrate material and decapods which are preserved as glassy black, similar to this specimen. Because of this, I'm inclined to think that this fossil is either from a vertebrate, or possibly a chitinous organism. I'm totally stumped either way though. I won't be able to provide any more photos unfortunately, as this one was left in the field. Note that this fossil was actually preserved in three dimensions - unfortunately I don't have a photo, but you can see on the leftmost split on the top half of the concretion that there's a plate that extends down into the concretion. This plate was roughly triangular in shape, and had gentle striations radiating from the middle point toward the ends. Thanks.
  17. Last summer, on the last day of a long weekend of backcountry fossil hunting around Lake Diefenbaker, Saskatchewan, my friend and I decided to stop our canoe at a beach where on a previous morning I had found a large baculites cuneatus specimen. This beach was an outcropping of a unit of the Bearpaw formation known as the Demaine sand, and dated roughly to the late Campanian. The locality was chock full of golfball to softball-sized nodules, each with a delicate, coalified fossil inside, ranging from crustacean parts, chips of driftwood, to loose vertebrae. It wasn't long before I was looking down at a split nodule containing the symmetrical lines I knew were a skull. So of course, I assembled it together as best as I could, wrapped it in a sock, and we loaded back into the boat to head home. Some typical terrain in the area. The formerly glacial South Saskatchewan River carves deep into the marine clays and sands of the Bearpaw formation: The nodule, rather unceremoniously wrapped in a wool sock: And unwrapped. Note the cervical vertebra just above the posterior end of the skull, and how part of the end of the snout is missing (sorry about the lack of scale bar, there's a photo further down the post with proper scale): I sent a photo to a paleontologist friend, and was quickly referred to the Royal Saskatchewan Museum, who of course were eager to accept the fossil (not to mention that I was technically legally obliged to hand it over, per the Saskatchewan Heritage Property Act... But it's what I wanted to do anyway!). About a month later, my friend and I met with two other paleontologists down at Lake Diefenbaker to deliver the fossil (this time more carefully wrapped in a shoebox...) and to show them the site where we had found it. One long and wet trip in the zodiac raft later, we were there. We assisted in the collection of more samples, this time coming up with an even broader variety of flora and fauna, including a small crinoid, some wood chips with amber, and some more decapods. One of the two paleontologists was excited to suggest that the locality probably represented a near-shore lagoon environment, and that the museum would likely be back to do some more work there at a later date. Unfortunately, we were unable to do so that summer because of the seasonally rising water levels of the lake, which flooded the site, but I've been told that my friend and I will be invited to assist with the operation again this following season. As for the fossil, it has since been delivered to McGill University to be CT scanned. Apparently, distinguishing the bone from the matrix has been long and tedious work, and not much news has reached us since the specimen was delivered some time last September. Here is an individual slice from the CT scan, from near the back of the braincase - notice how porous the bone material is, which is apparently another indicator that this skull belonged to a juvenile: I have been in close correspondence with the paleontologist from the Royal Sask. Museum who will be writing the paper to describe the find, but everything is more or less at a standstill until the work on the CT scan is finished. It's been a rather long wait, but I'm looking forward to its publication - I have been told that the museum intends to hold a press conference after the specimen has been described, and that my friend and I will be credited and involved in the reveal. So far, the museum has kept everything about the discovery deliberately vague, aside from a brief mention in a press conference, which informed an article that circulated around the Canadian media late last summer: https://nationalpost.com/news/canada/scientists-in-saskatchewan-discover-new-multimillion-year-old-fossils It's been an exciting and fulfilling experience overall, and I can't wait to get back into the field, this time with a more meticulous and careful attitude, knowing that there's scientific potential to be had from my future contributions. Anyway, here are some more photos from the lab at the RSM, with scale bar: Decapod claw: Crinoid crown: Thanks for your attention.
  18. Hi I decided to make this since the new Tyrannosaur from Alberta’s Foremost Formation, Thanatotheristes deerootorum has just been named and described. Enjoy!! Tyrannosaur bearing Formations in Canada: Formations in Alberta but most of the Formations on my list are I Alberta anyway.

Oldman Formation 78.2-77 million years ago, Alberta: Daspletosaurus torosus, Gorgosaurus sp. Foremost Formation 80.5-78.2 million years ago, Alberta: Thanatotheristes deerootorum, possibly Gorgosaurus sp. Milk River Formation 84.5-83.4 million years ago, Alberta: Tyrannosaur. indet could be a species of Thanatotheristes, possibly Gorgosaurus sp. Scollard Formation 68-66 million years ago, Alberta: T. rex, possibly Nanotyrannus Formations in British Columbia: Wapiti Formation 76.8-70 million years ago, Alberta, British Columbia: Unknown Albertosaurinae either Gorgosaurus or Albertosaurus, possibly Daspletosaurus sp. Tumbler Ridge 135-74 million years ago, British Columbia: Tyrannosaur. indet Formations in Saskatchewan and Manitoba: Dinosaur Park Formation 77-75.5 million years ago, Alberta, Saskatchewan: Daspletosaurus sp., Gorgosaurus libratus Frenchmen Formation, 68-66 million years ago, Saskatchewan: T. rex, possibly Nanotyrannus Bearpaw Formation 75-72 million years ago, Alberta, Saskatchewan, Manitoba: Daspletosaurus sp. one specimen from Daspletosaurus sp. that drowned. For now these are all the Tyrannosaurs known from Canada. No Eastern Tyrannosaurs in Canada yet either but maybe someday. I will also update this and add as more information comes available.
