From today's featured articleLimusaurus is a genus of theropod dinosaur that lived in what is now China during the Late Jurassic, around 161 to 157 million years ago. The only species, Limusaurus inextricabilis, was described in 2009 from specimens (diagram pictured) found in the Upper Shishugou Formation in the Junggar Basin. Limusaurus was a small, slender animal, about 1.7 m (5 ft 7 in) in length and 15 kg (33 lb) in weight, with a long neck and legs but small forelimbs. It underwent a drastic morphological transformation as it aged: while juveniles were toothed, the teeth were completely lost and replaced by a beak. This probably corresponded to a dietary shift from omnivory to herbivory. Since many specimens were found together, it is possible Limusaurus lived in groups. As referenced in its genus name, which means "mud lizard", specimens of Limusaurus appear to have been mired in mud pits created by the footprints of giant sauropod dinosaurs. (Full article...)

Stupas in Nepal date back to the Licchavi period. A stupa is a mound-like or hemispherical structure containing relics (such as śarīra – typically the remains of Buddhist monks or nuns) that is used as a place of meditation. Swayambhunath (pictured) is one of the oldest-known buildings in the country, and was likely built in the 5th century. It was built in Swayambhu, Kathmandu, where the land was declared as sacred to Siddhartha Gautama (Buddha), by Ashoka the Great, the 3rd emperor of the Maurya dynasty, in the 3rd century BCE. Ashoka's daughter Charumati, who married a Nepali prince, built Charumati Stupa in the 4th century. Boudhanath is one of the holiest sites in Nepal; it was closed for 18 months after the April 2015 Nepal earthquake, which completely destroyed the top part of the stupa. The World Peace Pagoda was built by Japanese Buddhists for about US$1 million; near the stupa is the gravestone of a monk who was murdered by an anti-Buddhist group while the building was being built. The Ramagrama stupa contains relics of the Buddha and it remains untouched in its original form. (Full list...)

Fractional currency, also referred to as shinplasters, was introduced by the United States federal government following the outbreak of the Civil War. These low-denomination banknotes of the United States dollar were in use between 1862 and 1876, and issued in denominations of 3, 5, 10, 15, 25, and 50 cents across five issuing periods. This fifty-cent fourth-issue banknote depicts Secretary of the Treasury Samuel Dexter on the obverse. The fourth issue had additional anti-counterfeiting measures in the form of watermarked paper, the embedding of large silk fibers, and blue-tinted end paper. This banknote is in the Smithsonian Institution's National Numismatic Collection. Other denominations:Banknote design credit: Bureau of Engraving and Printing; scanned by Andrew Shiva
