BBC has the full story on a 75 million-year-old giant sea turtle fossil that took a century and a half to put together:

Atlantochelys mortoni was originally described from a broken arm bone, or humerus, found in the 1840s in the US state of New Jersey.

Remarkably, the missing portion has also now been unearthed.

The fossil fragments are a perfect [...]

Nature tries to see what was behind the comet that killed the dinosaurs – and other mass extinctions that seem to happen every 35 million years. One guess: Our solar system passes through a disk of dark matter that knocks meteors and comets into our planet:

Meteorites regularly pepper Earth’s surface. Thirty years ago, physicists suggested that this bombardment [...]

Science Art: <i>Cotylorhynchus</i>, by Nix

The Tumblr illustrator Nix is having a paleoart February, creating a new illustration of a non-dinosaur, non-pterosaur prehistoric creature every day of the month.

…[T]he boy’s genome sequence shows that today’s indi­genous groups spanning North and South America are all descended from a single population that trekked across the Bering land bridge from Asia (M. Rasmussen et al. Nature [...]

And now, Discovery News says, we know what he looked like – the early human ancestor who lived with the dinosaurs:

This ancestor, the first placental mammal, lived between 88.3 to 91.6 million years ago, according to the study, published in the latest issue of Biology Letters. Placental mammals today include humans and all other mammals except those that [...]

Times of India reports that they’ve just found some pterosaur footprints in north India’s Jaisalmer Basin:

“Near the Thaiyat Village on the Jaisalmer-Jodhpur highway there is an outcrop of Jurassic rocks. Careful geological observation by the team allowed them to interpret ancient environments in which these rocks (once soft sediments) were deposited. We can imagine a vast coastal zone [...]
