  1. I could look at these all day, pictures taken with macro lens of exquisite baby creatures in deep water. However I found the last picture disturbing, shame on us humans.
  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

    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!
  4. Being a Colorado native, I have taken multiple trips to the public-access Florissant Fossil Quarry located near Florissant Fossil Beds National Monument in Florissant, Teller County, Colorado. This quarry provides fossil collectors fantastic access to the shale layers of the Florissant Formation, a late Eocene (Priabonian, ~34 million years old give or take) lagerstatte known for its diverse fauna of fossil insects, in addition to plants, gastropods, and very rarely vertebrates. Most fossils occur in very thinly laminated ashy grey shales. Other lithologies present include well-sorted tan course sandstones and well-sorted grey claystones. A lacustrine depositional environment is apparent, and though the Florissant Formation has previously been interpreted as the remains of a single large lake (the retroactively named Lake Florissant), it is now generally thought that deposition occurred across several smaller lakes, which of course shifted in their exact location throughout the period of deposition. This thread is for me to share some of my better quality (or more interesting) fossil insect finds from the Florissant Fossil Quarry, and to allow other people to share their Florissant insects. I intend on updating this thread as I make more collecting trips. Most insect fossils found at Florissant are of poor quality, however exceptionally beautiful specimens do crop up quite frequently. Regardless, identification even down to family level is usually very difficult, and some specimens I even have difficulty assigning to an order. Additional reading: https://bioone.org/journals/palaios/volume-27/issue-7/palo.2011.p11-084r/DEPOSITIONAL-SETTING-AND-FOSSIL-INSECT-PRESERVATION--A-STUDY-OF/10.2110/palo.2011.p11-084r.short Please note that at least for now picture quality is not ideal. I do not have the capacity to take good quality macro photographs, but I am doing the best that I can. The scale of the ruler is millimeters, magnification (when applicable) is noted. Order Diptera (True flies): Probably my best-preserved Florissant insect (and one of the first ones I ever found). Another fly. I'd like to be able to identify this one to family (and it almost certainly is identifiable to family) but I haven't been able to place it. This is a gorgeous fossil! Magnified 20X under a stereo microscope. Another gorgeous fossil fly. Possibly a gnat (suborder Nematocera), but I'm not 100% on this identification. Partial fly of indeterminate family, most of the abdomen is apparently missing. Both wings are preserved, the thorax and head are also nicely detailed. This is an example of a march fly (Family Bibionidae), probably the most common insect at Florissant. Many specimens (such as this one) are preserved without their wings. The head and mouthparts are very nicely preserved here, I feel shameful that I could not manage a better photograph. Crane fly, (Family Tipulidae). The preservation quality is not fantastic, but the gross anatomy can be easily made out (both wings, the abdomen, thorax, head, eyes, and even the halteres and some of the legs are present). Order Hymenoptera (Bees, ants, wasps, and relatives): A nice solitary bee (clade Anthophila). The details are not as high-fidelty as some other Florissant insects, but a nice complete specimen. Order Hemiptera (True bugs): Magnified 20X under a stereo microscope. A shield bug (superfamily Pentatamoidea). This is a really neat specimen because fossil Hemipterans aren't particularly common. Indeterminate Order: A large insect that I've never quite been able to place. Two wings are very faintly preserved which would normally be indicitave of a fly, but this specimen just doesn't look much like a fly otherwise. The antennae are interesting, it's a very large insect, and the tibia has an interesting flange. Unfortunately I can't seem to get a good look at the mouthparts (which has been very useful for me in the past for identification). Magnified 20X under a stereo microscope. At first I thought this might be an ant (family Formicidae) but under magnification the shape of the head is more suggestive of a fly. Very poor preservation, I'm not confident I'll ever get a solid answer here. Larvae: A nice plump fly larva, looks to me to be from a botfly (family Oestridae) or a relative. A very strange fossil. The segmentation and tagmosis definitely means this is an arthropod of some sort, and an insect larva is my current interpretation. Still, I've never seen anything quite like it. I've had a few people suggest to me this might be the abdomen of an earwig, but that's definitely not the case (earwig cerci do not look like this or articulate with the abdomen in this manner). Non-Insect Invertebrates: Just an example of one of the tiny gastropods that are common. It takes a keen eye to see them, but once you can recognize them you realize they're very plentiful. If you have some fossil insects from this locality in your collection, feel free to post them here too! Cheers!
  5. Location: Colorado Time: Late Eocene Epoch Formation: Florissant Formation Hello! I had the fortunate opportunity to visit the famous Florissant Fossil Quarry in Colorado and was able to collect some amazing stuff before the rain ended our class fossil hunting ventures. Nevertheless I have at least 3 insects that I was hoping I could ask for identifications on for here! I also added some of my plant fossil finds if anyone can recognize those too it would be great! Found this little fly guy Mosquito? or something else? Insect larvae? Or just missing the wings? To me this looks like a possible larvae of some insect, but the wings present in the top right might suggest another story, what do you think? All of my insects just so happened to be next to each other with some amorphous plant debris Fossil Flower? I spotted this guy right as we arrived lying in a mound by the road Sorry for the grainy photos, this guy just could not focus for the life of me Leaves: Other plant material: Couldn't really categorize this one. It was very weird to say the least as it looks very plant like but I have a feeling it could be something more.

    Petrified wood with grubs

    Around 40 years ago my dad dug up this fossil, he worked in construction so it was likely not in the original location but perhaps in an old garden or waste pit. As a child I broke off the large grub, sorry! I was trying to get a closer look. Just wondered where this might have originated, what the insects were and what type of stone now inhabits their bodies, is it quartz? Found in England (Bedfordshire, Buckinghamshire area)
  7. Went up to Douglas Pass, Colorado today for a hike with my wife. I have always hunted for fossils at the Radar Dome location. Today we decided to scout around for another location to collect. Hiked up a very steep hill to a shale exposure and found this larvae after only 1 minute of looking. We had not come prepared today to collect anything. Will probably head back up next weekend. The larvae is approx 2.25 cm across. There are also some parts of other larvae on the piece.
