Iguana-Sized Reptile Roamed Antarctica 250 Million Years Ago

Along the banks of a river, three archosaur inhabitants of the dense Voltzia conifer forest cross paths: Antarctanax shackletoni sneaks up on an early titanopetran insect, Prolacerta broomi lazes on a log, and an enigmatic large archosaur pursues two unsuspecting dicynodonts, Lystrosaurus maccaigi.

Some 250 million years ago (early Triassic epoch), an early relative of dinosaurs and crocodiles lived in what is now a frozen continent, Antarctica, according to an international team of paleontologists from the United States and South Africa. Along the banks of a river, three archosaur inhabitants of the dense Voltzia conifer forest cross paths: Antarctanax shackletoni sneaks up on an early titanopetran insect, Prolacerta broomi lazes on a log,...

The two Moon-exploring crew men of the Apollo 14 lunar landing mission photographed and collected the large rock pictured just above the exact center of this picture. The rock, casting a shadow off to the left, is the lunar breccia 14321. It lies between the wheel tracks made by the modular equipment transporter (MET) or rickshaw-type portable workbench. A few prints of the lunar overshoes of the crew members are at the left. This photo was made near the boulder field near the rim of Cone Crater. Image credit: NASA.

A 30,000 light-year region from the Renaissance Simulation centered on a cluster of young galaxies that generate radiation (white) and metals (green) while heating the surrounding gas. A dark matter halo just outside this heated region forms three supermassive stars (inset) each over 1,000 times the mass of our Sun that will quickly collapse into massive black holes and eventually supermassive black holes over billions of years.
