  1. I was recently out vacationing in Wyoming and spent Saturday morning (7/24/21) hunting in the badlands. As I sat down to rest for a moment, I looked down and saw what I thought were a radius/ulna pair from a small mammal. Upon closer inspection, it was a pair of lower jaws freshly exposed on the edge of a nodule and on the backside, a small skull. Needless to say, I was ecstatic. I spent a bit of time making sure the specimen was consolidated (Paleobond Penetrant, wish I had brought some 4417) and packed it up for the trip home. I was thinking it woul
  2. With a week of collecting under my belt I felt ready and excited to take on the next, this time exclusively on the White River formation. All factors being considered, the White River is probably the most difficult formation to hunt among those I've been lucky enough to explore thus far. For one, the terrain is often very rough, with all sorts of ridges, rises, washes and gullies to hike through. Another issue to account for is the reflection of light off of the white sediments, meaning that ample sunscreen is a necessity if you don't want to burn to a crisp. That harsh sunlight can lead to te

    Lincoln Creek Composite Shell Piece

    Picked up a few more shells from the Lincoln Creek Formation while out on a walk, and thought it would be fun to make a composite piece with them. Was pretty easy, just used superglue to fix a couple of moon snails and a scaphopod to a tiny slab of shale from the formation. For my first composite piece I don't think it looks bad, but I was obviously a little too excessive with the glue.

    Mystery Jaw from the Badlands

    I bought this large jaw section at MAPS a couple years ago. It was labeled fossil jaw Badlands and that's it. I've collected the Badlands of Nebraska, Wyoming, and South Dakota many times and built a large collection of fossils from these localities. However this jaw has stumped me. My thought was the large Miocene Oreodont Promerycochoerus. Any input will be appreciate. The size of the jaw is 153mm or a little over 6 inches long. The rear molar is 50 mm or 2 inches long. Thank You.

    Oligophus moravicus (Pauca, 1931)

    Alternative combinations: Diaphus moravicus and Leuciscus moravicus. Taxonomy according to Fossilworks.org. Description of Oligophus moravicus according to Přikryl et al. 2017, pp. 219-220: “The following description is based on the almost complete specimen Tv 1023a and its counterpart specimen Tv 1023b. They show a preorbital length much shorter than orbit diameter. The head is rounded, with an antero-dorsally oriented mouth. The lower jaw joint is located far posterior to the posterior-most margin of the orbit. The maxillary is slender throughout. There is no indication of a supram

    Propteridium sp.

    Very probably Propteridium profondae Ciobanu, 1970. Taxonomy according to Přikryl, 2018. From Fahay, 2007, p. 649: “The order Ophidiiformes (sensu Cohen and Nielsen 1978; Nielsen et al., 1999) contains the suborders Bythitoidei, viviparous forms with an external intromittent organ, and Ophidioidei, oviparous forms with pelvic fins at level of preopercle or farther anterior, and caudal fin confluent with dorsal and anal fins.” Description of Propterides profondae according to Přikryl and Carnevale, 2018, p. 482: “The head is more or less triangular in shape; its length is contain

    Propercarina sp.

    Probably Propercarina cf. rebeli Pauca, 1929. Alternative name: Palimphyes cf. rebeli (Pauca, 1929). Taxonomy according to Fossilworks.org. Diagnosis for the genus Propercarina according to Prikryl et al., 2014, p. 693: “Emended diagnosis (according to Pauca, 1929, 1934 and Bannikov, 1995, 2010, modified): Body elongated. Dorsal and ventral edges of body are almost parallel and they run alongside the axis of the vertebral column; the body is covered by small cycloid scales; the lateral line is parallel to the dorsal edge of the body and runs just dorsal to the vertebral column;
  8. I just got back from an amazing and very fruitful week of fossil collecting on the White River Formation in northeastern Colorado. The White River Formation is a very easy and fun rock unit to collect vertebrate fossils on. The White River Formation was deposited during the very latest Eocene and the early Oligocene, though the faunal diversity in the areas I was collecting on suggest it was laid down during the Orellan North American Land Mammal Age, which centers on around 33 million years ago during the Rupelian age of the Oligocene Epoch. I am very lucky to have a grand uncle

    Billfish

    Sharing one of many finds this week and another hike planned next week. Early Oligocene, billfish concretion of the Lincoln Creek Formation. Additionally, several large whale vertebrae found, coral, sponges, shark vertebrae and dolphin. My apologies for not frequenting TFF as often as I should, getting old and napping more. 1st image: shark vertebra, 2nd: billfish, 3rd: whale vertebra, 4th: billfish vertebra. Chopping fallen trees to the site.. with pickax. My collection for a chain saw.

    Cenozoic salamander

    This has bugged me for years. It's a small amphibian or reptile ( 8cm long) found at Fossil OR at the high school site. The strata is tuffaceous siltstone famous for leaf impressions. It's part of the John Day formation, oligocene in age. I have read that salamanders are occasionally found there but cannot find any more information as to species or anatomy. I was even wondering if it could be a snake with vestigial femurs. I'm hoping that someone can provide me some specifics so I can finally finish cataloging this specimen.
  11. New fossils of giant rhinos — the largest land mammals ever — are found in China (nbcnews.com) Giant rhino unearthed in China was one of largest mammals ever to live | New Scientist New fossils reveal one of the largest land mammals ever found (yahoo.com) Since the late 2000s, scientists from China have treated Paraceratherium grangeri as a distinct species from Paraceratherium fossils found in Central Asia (named Indricotherium by Aleksei Alekseeivich Borissiak in 1916), and the taxon P. huangheense described in 2017 further indicates that not all fossils of Paracerather
  12. I found this front bit of carnivore jaw while out on my latest fossil collecting trip in the White River Formation of Colorado. Only one tooth is complete, the canine tooth has broken off. It’s too large to be Hesperocyon and the cross section of the canine tooth does not match that of Daphoenus, which I have previously collected material, including a canine tooth, from. That leaves Hyaenodon and the Nimravids. After doing some comparative research with pictures of skulls, I am tentatively leaning towards this being from a Nimravid, as the contours of the jaw line near the socket
  13. I have a few really nice fossils from the White River Formation of northeastern Colorado that I need to prep, and given I am a beginner at fossil prep I would really like to gain some advice and guidance from people with experience do I don’t accidentally damage the fossils. The first fossil is an Oreodont skull. The skull is mostly intact, and I was able to extract it from the field without using any glue or stabilizer or consolidant or anything like that, so this fossil is in its “natural state.” The zygomatic arch and upper tooth row are crumbling, but
  14. The spikefishes are related to the pufferfishes and triggerfishes. Taxonomy according to GBIF. Diagnosis after Tyler et al., 1993: "Carpathospinosus differs from all other Triacanthodidae by the first dorsal spine with a longer average relative length (37% SL versus 24%-34%) and the second dorsal spine considerably shorter, with an average relative length at the low end of the range of length in other triacanthodids (15% SL versus 13%—29% SL), its length contained an average of 2.4 times in the length of the first spine (versus length of second spine contained an average of 1.1-1.4 t

  16. I'll be honest, I've put off writing this trip report for far too long. Between work, school and general procrastination I have delayed this post for over 7 months. Perhaps there's a silver lining to me writing this in the middle of winter, it could act as a nice break from the grey & cold conditions many of us are facing this season. Hopefully you all enjoy a dose of warmth from a trip which I enjoyed greatly. Ok ready? Let's go. My morning started around 4:30, ungodly hours for me generally, but I woke up excited for what lay ahead. Less than a half hour later we were on our w
  17. I tend to buy a copy of every issue of Natural History magazine to encourage the local Barnes & Noble to continue carrying it. Sometimes, it's already gone when I get there, and last year, the magazine suspended publication for a few months due to COVID. In the current (May) issue, the cover story is "The Story of the Rose." It reviews the known fossil history of the flower against the background of paleogeographic and climatic changes across the Cenozoic Era. It also addresses how humans have valued roses going back as far as a few thousand years and how we have found uses
  18. I have some Gansu fossils from the Linxia Basin, but I wasn't 100% sure on ID. The teeth were sold as Entelodont molars, and my current assumption is that they belong to Paraentelodon macrognathus from the Oligocene deposits in the Linxia Basin. From what I've read, they are similar to Daeodon, at least size wise. I think the formation would be the Jiaozigou Formation? But I'm not entirely sure. The Chleuastochoerus jaw, i have no idea. I think there are 2 species present in the Linxia Basin, and I don't know if it's possible to ID them down to species leve

    Oligocene Dolphin

    I just finished up preparation on this amazing Oligocene dolphin. It is from the Ashley formation and is a real beauty. I made the decision not to completely remove it from the matrix, as I believe it is more aesthetic this way.. It was missing the last 3 inches of the pre-maxilla so that had to be restored but we did find a few other teeth in the matrix.
  20. Hello fellow fossil hunters. Below is a photo of the array of fossils I found. Each fossil is labelled with a number and it would be awesome if I could get each one identified. I thought ahead and took the photo on grid paper with each square being 5mm. Item 1 is just some quartz crystal I picked up, item 4 is a piece of some unidentifiable shell and the rest are legit fossils. I am a rooky and an amateur so please let me know if I get anything wrong or if I need to add any more detail. Location: Batesford Limestone quarry, Geelong, Victoria, Australia. Geology: Sometime betw

  22. Hello all, Was hoping for some help identifying some recent finds from the Charlie Creek in the Peace River of Florida. I'm still a novice with ID'ing so I was hoping for some guidance as to where I I went right and wrong. I believe they are, in order: a worn cetacean tooth, turtle nuchal scute, a fragment of stingray barb. The last set I am unsure of. Perhaps some bird clavicles? Thanks for any help you can give, Al

    Cobitopsis acutus (P. Gervais, 1847)

    This fish belongs to the Hemiramphidae family (Halfbeaks) within the order Beloniformes; The halfbeaks are named for their distinctive jaws, in which the lower jaws are significantly longer than the upper jaws. Halfbeaks hunt insects and fish at the water surface in sometimes large groups. Reference: J. J. Sepkoski, Jr. 2002. A compendium of fossil marine animal genera.

    Nimravid! But which one?

    Hi guys! Recently I got in a trade this nimravid mandible from the white river formation in Shannon County. Now I want to ask your help to determine the genus, if possible. Being incomplete and missing all the teeth it's quite difficult but it has a quite elongate mandible flange and by the number of the alveoli it had three teeth. I think it can be Hoplophoneus, what do you think about it?
