  1. For #FossilFriday—dinosaurs headline the Minnesota State Fair, but an Ice Age predator is also on display!

    These 26,900-year-old Homotherium serum fossils from Tyson Spring Cave include a skullcap, shoulder blade and foreleg. Found beginning in 2008, they provided the first record of this scimitar-toothed cat in Minnesota and the Great Lakes region.

    See them through Sept. 7!

  2. 🐻 For #FossilFriday 🐂🦥🐴🐪🐟 a new #LostBones article is out on Substack! This one is a deep-deep dive into brown bear (Ursus arctos) and giant short-faced bears (Arctodus simus) in the Midwest and Surrounding areas.

    Please share to get out the word!

  3. New research in northern Chile reveals 76 ancient stone traps used to hunt vicuña across the high Andean valleys. These “tethered landscapes” show how mobility, cooperation, and ecology shaped Andean lifeways. #Archaeology #Andes #BehavioralEcology #Pleistocene anthropology.net/p/the-tethere

  4. 🐴 #LostBones #FossilFriday 🐟🐘🦥🐪 In the summer of 2012, students from the Geology Department at Gustavus Adolphus College collected over 800 bones on the Des Moines River near Jackson, Minnesota.

    This crunchy but beautiful left horse femur was part of the project and is now housed at the Jackson County Historical Society in Lakefield.

  5. 🦌#Minnesota #FossilFriday 🐂🦥🐴🐘🐪🐟🍃Remnants of deer and bison are common along many Minnesota rivers. Teeth, metacarpals, metatarsals, and some long bones withstand the erosive forces of rivers particularly well.

    These specimens were all found during a single kayak trip this field season, along just a two-mile stretch of river in southern Minnesota.

    A remarkable find: Two neighbors contributed a total of 100 bison bones, discovered in separate years from the same lowland peat deposit spanning a highway in Walcott County, Minnesota. Notably, one of the collections shows possible signs of butchery.

    Both collections are now at the Rice County Historical Society in Faribault, Minnesota.

  7. It’s a #lostbones #FossilFriday! 🐂🦥🐴🐘🐪🐟🍃 A revisit to the Bison skull at the Anoka County Historical Society in central MN! This time for skull metrics. The skull, discovered in the 1970s, has a 72cm core span.

    It turns out the peat-bog bovid had some friends. After working with staff, we found the collection has partial remains of up to four bison - four right mandibles!

  8. It’s a #lostbones #MammothMonday 🦣🦥🐴🐪🦬🐟 This mammoth specimen is not from #Minnesota but you can see it here.

    Found in Miles City, Montana, this partial Columbian mammoth femur is housed at the Pipestone County Museum. It is currently not on display but a partial tusk and jaw from the same Montana doner are. More to come on those!

  9. It’s #Minnesota #FossilFriday! 🦥🐃 🐘 🐴🐪🐟🍃There are no documented Pleistocene-age horse specimens in Minnesota. The small size of this m3 tooth has me hopeful. It's about 25mm in length across the crown.

    Found by a friend on a river gravel bar it will be donated to the Science Museum of Minnesota for further study.

  10. The #glacier went that-a-way

    The #striations on this face of the #Ediacaran (ca. 560 Ma) #Squantum Member of the #Roxbury #Conglomerate were probably left by the #Pleistocene #Laurentide ice sheet, which retreated ca. 12 ka. The striations have the right orientation, from northwest to southeast.

    The Squantum Member was once interpreted as a (#glacial) #tillite. The most common contemporary model is a peri-#Gondwana #debrite (#turbidite).

    Its #MammothMonday Jim van Dijk has spent the last few months building the world's first reconstruction of a southern mammoth for the Museum Historyland Hellevoetsluis in Hellevoetsluis, Netherlands.

    Not only is the sculpture just an awesome site but Dick “Sir Mammoth” Mol was a consultant on the project.

  12. It’s #Minnesota #FossilFriday! 🦣🐪🦥🦫🐴🐟🍃 This beautiful Bison occidentalis skull is housed at the Anoka County Historical Society. Found in a black dirt pit near Andover it was donated in 1977 along with related vertebrae, long bones, pelvis, ribs, shoulder blades, and carpals.

    The skull’s horn span across the cores is 75cm, nearly 30 inches!

  13. Missing #Mammoth! 🦣🐪🦥🦬🦫 The New Ulm, MN mammoth tusk is missing! If you are wondering where it went – it’s back at the Science Museum of Minnesota where it is being fitted for a new display case!

    The Brown County Historical Society is working with the museum’s exhibit services team to create a case that will keep the tusk safe and stable for generations to come. 🦣

  14. It's #Minnesota #FossilFriday! 🐟🐪🦣 Xiphactinus or Ichthyodectes, that is the question. This vertebra was found on a gravel bar in Southern Minnesota by a friend.

    Xiphactinus and the smaller Ichthyodectes were 3-6 meter fish that swam the Cretaceous Western Interior Seaway which covered the central United States for over 40 million years. 🦫🦬🍃

    Now donated to the Science Museum of Minnesota.

  15. Happy #Minnesota #FossilFriday! 🦬🍃🦣🐪🦥 Here is a beefy Bison bison humerus found last fall by a friend of mine in Southern Minnesota. It was found eroding out of the side of a small tributary about 4 feet below the soil surface – just downhill from a tee box on a local golf course. ⛳

    It has since been donated to the Science Museum of Minnesota for further study.

  16. It's #Minnesota #MammothMonday. 🦣🦷 More Southern Minnesota proboscideans! - see my previous #MammothMonday posts. Here's a partial tooth found in 2019 by a friend. It was stuck in the muddy river bottom along a cut bank. Surprisingly not fully tumbled apart - the rest of the animal could be close! Donated to the #sciencemuseumofmn. 🦣🦥🐴🐪🦬🍃
