Happy #FossilFriday! 🐴🐘🐪💀 This gorgeous horse mandible comes from Brown County, Minnesota. It was collected by a friend of mine under permit in a state park earlier this year. The bone is deceptively heavy, suggesting it has been partially mineralized. Today, it will be donated to the Science Museum of Minnesota for study.

Journal Nature: Modern sea-level rise breaks 4,000-year stability in southeastern China - https://www.nature.com/articles/s41586-025-09600-z

One of the first studies to address sea-level budgets for regions outside North America's east coast, the researchers looked in-depth at available data for the entirety of the #Holocene in #China. With many of China's megacities sited on deltas, they note up to 1 m subsidence due primarily to ground water extraction, exacerbating predicted #SeaLevelRise.

I did something.
It's about the ColdBlob or SubPolarGyre or AMOC.
Specifically, about finding proxy locations on land for its annual evolution.

Taking SPG average sst in the months DJF and MAM, and computing also their year-on-year growth rate.

Then I computed the growth rate for DJF and MAM in all coordinates on land using Era5-Land 1951-2025.
And when the growthrate matches that of SPG within ±0.5 °C, it gets a ✅ .
6 ✅ per decade gets a 🔵 and counts toward selection.
Some more exclusion criteria applied, and I get a list of 315 locations on land for 🔵matching DJF growthrate, and a whopping additional 11,460 locations for MAM
In a 0.1x0.1 grid.

All DJF locations are in Papua. No proxies I know of have been recovered from Papua yet. I know all speleothems / stalagmites in caves🔴 , and all treerings ever analyzed🟢 , thanks to #NOAA .

But MAM °C has more locations. All of Indonesia basically is THE SPG in terms of growthrate. A few trees and speleothems match, one cave covers the whole #Holocene 🖖🏽
Large patches in Africa also match SPG in MAM. But only 2 short treering studies exist. No caves.
Middle and South America has plenty matching SPG MAM too, and a handful of trees and caves.

Yay.

Ancient lakes in the Gobi Desert supported human life 8,000 years ago

The Gobi Desert today is one of the driest and harshest landscapes on Earth, stretching over northern China and Mongolia. Yet, a recent study published in PLOS One reveals that thousands of years ago, the desert was dotted with wetlands and lakes that nourished fertile ground for human life...

Humans profoundly reshaped mammal communities on a global scale.

"After farming began, just a handful of livestock species spread with humans and scrambled those natural boundaries, reshaping mammal communities worldwide...Large ungulates like horses and cows are important because they monopolize food resources wherever they are in high numbers...At the same time, many wild mammals went extinct, in each case following human arrival—not during a particular worldwide climate change episode."

"Post-extinction ecosystems have not been truly natural for the last 10,000 years or more, so national parks in the hardest-hit regions, such as Australia and the Americas, lack over half of the native large mammal species that would have been present if not for humans. Over the last 10,000 years or so, humans have overseen the wholesale replacement of native mammal communities with a very limited set of domesticated species."

How humans reshaped the animal world: Research traces 50,000 years of change
https://phys.org/news/2025-09-humans-reshaped-animal-world-years.html

"These findings underscore how human-driven extinctions, agriculture and resource extraction profoundly reshaped mammal community structures. How we manage these interactions today will determine whether mammal communities become resilient or increasingly destabilized."

This should be very interesting. Neanderthals were doing extensive burning 125 Ka so this should reach back a long way, certainly prior to #Holocene
