#LostBones #FossilFriday #RadioCarbonDating 🐂🦥🐴🐘🐪In June 1921, workers removing the overburden at the Sagamore Mine near Riverton, Minnesota uncovered a peat layer ~eight feet below the surface that held a rich Pleistocene bone bed. Among the material recovered from this layer were a horse molar (specimen #6) and an horse incisor, found alongside other late‑Quaternary remains within the same sedimentary zone.

Happy #LostBones #FossilFriday! 🐴🦣🐂🦥🍃🐪🐟 Was on the road this week with @dr_crocogator to retrieve specimen #4! This beauty of a horse molar (right p2) is from Wright County, Minnesota.

It was found on the shore of Olson’s Point on Buffalo Lake in 1976 and was currently housed at the Wright County Historical Society in Buffalo.

Excavation at a development site in Lynnwood, WA shows stratigraphy from the recent past, geologically speaking. An over 3,000 foot thick ice sheet covered the area that melted away 12,000 years ago. The lower dark gray layer is till, a mix of clay, silt, sand, gravel, etc. that was smeared and packed under the ice sheet as it advanced. Very dense. Above that is some clay/silt sand/gravel, not as dense, may be weathered till or outwash. The contact is abrupt. #geology #Pleistocene #glacier

The oldest sewn hide ever found came from an Oregon cave. It’s elk, stitched with plant-and-hair cordage, and it dates to 12,000 years ago when winter survival depended on fitted clothing. #Archaeology #Pleistocene #GreatBasin https://www.anthropology.net/p/the-oldest-sewn-hide-in-the-world

430,000-year-old well-preserved wooden tools are the oldest ever found

Researchers working in southern Greece have identified the oldest known handheld wooden tools, dated to about 430,000 years ago. The objects came from Marathousa 1, a site in the Megalopolis Basin in the central Peloponnese. The area once held a lakeshore during the Middle Pleistocene, a period between about 774,000 and 129,000 years ago...

🐴 #LostBones #FossilFriday — Twelve horse teeth from across Minnesota are headed for radiocarbon dating.

This pristine specimen #3 comes from Flower Valley near Red Wing. It was found by Shari Albers when she was ten, discovered as her dad worked a field.
