From today's featured articleViatkogorgon is a genus of gorgonopsian (a type of therapsid, a group that includes modern mammals) that lived during the Permian Period in what is now Russia. The first fossil was named as V. ivachnenkoi after the paleontologist M. F. Ivakhnenko. It was found at the Kotelnich near the river Vyatka in 1999. The holotype skeleton (pictured) is one of the most complete gorgonopsian specimens known and includes some rarely preserved elements, including gastralia and a sclerotic ring. A larger, less well preserved specimen has also been assigned to this species. The smaller specimen is about 80 cm (31 in) long, including the 14 cm (5.5 in) skull, and may have been a young animal. It was robust with a dog-like stance, high snout, and very large canine teeth. Gorgonopsians would have been relatively fast predators, which killed their prey by delivering slashing bites with their saber-teeth, and this genus may have been adapted for swimming.

Today's featured picture
Pigeon Point Lighthouse is the tallest lighthouse (tied with Point Arena Light) on the West Coast of the United States, located in San Mateo County, California. It stands on a rocky promontory and has long been a landmark for ships approaching San Francisco Bay from the south. This headland, and hence the lighthouse, took its name from the ship Carrier Pigeon, which was wrecked here in 1853. Photograph credit: Frank Schulenburg
