A school nature club fossicking on the shore of Kawhia Harbour in 2006 thought they had found a rusty boat propeller set in the mudstone — it took scientists 15 years to name what the children had actually dug out: a new species of giant penguin, 1.4 metres tall, that swam over the Waikato as much as 34 million years ago

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…...

More than 10 million years ago, South America had saber-toothed mammals, terror birds and giant snakes. But fossil evidence suggests even its apex land predators could become prey near the water, where the enormous caiman Purussaurus neivensis ruled.

3+ week, 3+ day ago   (1377+ words) Four tooth pits in a terror bird's leg point to a 4.6-to-4.8-meter caiman, probably Purussaurus neivensis, but the fossil cannot distinguish a kill from scavenging.

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.

Scientists uncovered a bizarre crocodile cousin from 215 million years ago that started life walking on all fours, then changed its entire stance as it grew — by adulthood it was standing upright and striding around on two legs

1+ week, 6+ hour ago   (470+ words) A crocodile relative in ancient Arizona underwent a radical transformation during its lifetime, shifting from four-legged crawler to upright biped—a developmental puzzle that rewrites what scientists thought possible for reptiles.
