🐴🐘🐪 This tooth survived the end of the Ice Age in a gravel pit. 🦷

Found 5 miles east of Montevideo, this lower horse molar may have belonged to one of the last Equus roaming Minnesota before their disappearance from North America. It’s tooth 10 in the 12 specimen project tracing Minnesota’s Ice Age horses.

🦥🐴🐘🐪 #FossilFriday — A lower horse molar (SMM P2025.8.7) from Olmsted County is specimen 9 of 12 headed for radiocarbon dating.

Olmsted County has produced multiple Ice Age finds over the years, including several mammoth tusks and both mammoth and mastodon teeth from county gravel deposits—many of which I’ve posted about previously.

👇 What will the dates show—Ice Age or more recent?

#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.

🐴 #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.

🐴 #LostBones 🐘🦥🐪 For #FossilFriday, a new series: 12 horse teeth from across Minnesota, each one headed for radiocarbon dating to finally pin down when these animals moved across the state’s post glacial landscape.

Specimen #1 comes from a private collection near Little Sauk, Minnesota — a single horse tooth pulled from a skull found in the black marl of the Sauk River.

How do they fit into the lives or paleo-Minnesotans?

🌴🔍 "Groundbreaking" findings about #Rapa Nui's "isolation" were so earth-shattering that even the internet refused to serve them. 🤦‍♂️ Who knew radiocarbon dating had such hard limits... like server security policies? 🚫💻

Radiocarbon dating reveals Rapa Nui not as isolated as previously thought

Is there something fishy about radiocarbon dating? https://3quarksdaily.com/3quarksdaily/2023/05/is-there-something-fishy-about-radiocarbon-dating.html #Creationism #RadiocarbonDating #ChickTracts #BigDaddy #AlfredTheGreat

How many undergraduates can you fit in a radiocarbon dating laboratory?

About 60 Earth and Environmental Science students it seems.

And a fish-eye lens helps

Of course, as often as preservation conditions allow further analyses, a chronological frame set up this way,
is sought to be backed by further scientific dating methods, of which #RadiocarbonDating of organic remains might be the most familiar:
