From today's featured articleMegarachne was a predatory freshwater arthropod of the order of eurypterids, often called sea scorpions. Two fossil specimens of the genus have been discovered, in San Luis, Argentina, in deposits of Late Carboniferous age from the Gzhelian stage. Megarachne ("great spider") was initially misidentified as a spider. With a body length of 54 cm (1.77 ft), it was a medium-sized eurypterid, similar to others within the Mycteropoidea, a rare group known primarily from South Africa and Scotland. The mycteropoids evolved a specialized method of feeding referred to as sweep-feeding, raking through the substrate of riverbeds to capture and eat smaller invertebrates. Due to their fragmentary fossil record and similarities between the genera, Megarachne and two other members of its family, Mycterops and Woodwardopterus, have been hypothesized to represent different developmental stages of a single genus.

View from Stalheim is an 1842 oil-on-canvas painting by Norwegian artist Johan Christian Dahl, depicting the view from the village of Stalheim, in the county of Vestland in western Norway. A major work of Romantic nationalism, it is regarded as a national icon and one of Dahl's best works. The scene overlooks the Nærøy Valley, with the sugarloaf-shaped peak of Jordalsnuten in the background, framed by other peaks and a rainbow. A small village in the centre is illuminated by the late afternoon sun. One of Dahl's purposes in the painting was that of realism; the other was to capture the glory and magnificence of the mountains, and his country's culture associated with it. He had trouble with the painting, and avoided similarly large works after its completion. The painting is now in the collection of the National Gallery in Oslo. Painting credit: Johan Christian Dahl
