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.

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.

New reconstruction of the skeleton of the 375-million-year-old fossil fish, Tiktaalik roseae. In a new study, researchers used Micro-CT to reveal vertebrae and ribs of the fish that were previously hidden beneath rock. The new reconstruction shows that the fish’s ribs likely attached to its pelvis, an innovation thought to be crucial to supporting the body and for the eventual evolution of walking.
