136 long-clawed shrew skulls from Hokkaido showed the classic winter flattening of the braincase, and across the same series the snout enlarged in winter and shrank again in spring

1+ day, 9+ hour ago   (595+ words) A museum series of Sorex unguiculatus from Tomakomai confirms Dehnel's winter braincase shrink in an Asian shrew, and adds a reverse pattern in the snout that the authors did not find in the jaw. By Natural History · Edited by Chris…...

On May 28, 2020, a slab of gray Rhaetian bone in the mud at Blue Anchor, Somerset, went into the bag of Ruby Reynolds, 11, and her father. The surangular that was pieced together, fragment by fragment, until October 2022 preserved 145 centimeters of a jaw that ran past 2 meters, from an ichthyosaur about 25 meters long

5+ day, 11+ hour ago   (87+ words) A father-daughter fossil hunt in a Somerset mudflat yielded the largest ichthyosaur jaw bone ever found—and upended what scientists thought they knew about these ancient marine giants.

An unknown human lineage interbred with our ancestors in Africa more than 50,000 years ago — and although scientists still don't know who these humans were, traces of their DNA survive in every modern population studied.

1+ week, 5+ day ago   (1147+ words) A new genomic method detected roughly 0.49% to 1.1% ancestry from an unidentified human population across five sampled groups. The signal points to mixing in Africa before the main out-of-Africa expansion, but it has not been matched to a fossil species. By…...

Dimetrodon — the sail-backed predator routinely mistaken for a dinosaur — first appeared roughly 60 million years before the earliest dinosaurs and was actually more closely related to humans than to T. rex.

3+ week, 2+ day ago   (1080+ words) Dimetrodon lived in the Permian, before dinosaurs, and belonged to Synapsida, the same major evolutionary branch that later produced mammals.

In a Norwegian cave in 2025, scientists found 75,000-year-old bones of polar bears, walruses, and bowhead whales — and the remains of a species of lemming now extinct in Europe that had never been found in Scandinavia before

4+ week, 1+ day ago   (918+ words) A 2025 PNAS study identified 46 vertebrate taxa in a northern Norwegian cave deposit, revealing a coastal Arctic community from roughly 85,000 to 71,000 years ago.
