Unraveling the Mysteries of Utroba Cave

The opening and closing of the Rocas Verdes Basin, a back-arc basin in Patagonia, as described by researchers at The University of Texas at Austin in a study published in Geology. Panels B and C illustrate the basin-closure process, in which an underlying portion of the oceanic crust is thrust into a magma chamber (B) and breaks off ahead of continental crust (C). The last two panels (C and D) show the oceanic plate and continental plate colliding together – squeezing the basin together into the Andes Mountains of Patagonia that we see today.

New step in tectonic squeeze that turns seafloor into mountains

The zircon crystals we found in river sand and rocks from Finland have signatures that point towards them being much older than anything ever found in Scandinavia, while matching the age of Greenlandic rock samples. Photo: Andreas Petersson.

Do some mysterious bones belong to gigantic ichthyosaurs?

Art by James Havens Nanuqsaurus, standing in the background, and pachyrhinosaurus, skull in the foreground, were among the dinosaur species included in a new study led by scientists at the University of Alaska Fairbanks and the University of Reading that calls into question Bergmann’s rule.

Dinosaur study challenges Bergmann’s rule

Herrerasaurus ischigualastensis is an early saurischian dinosaur. It shared a bipedal, running anatomy common to large carnivorous dinosaurs that would evolve in the future, but this dinosaur lived at a time when dinosaurs were small-bodied and rare.

Early dinosaurs grew up fast, but they weren’t the only ones
