From today's featured articleSiamosaurus is a genus of spinosaurid dinosaur from what is now Thailand in the Early Cretaceous period. The first reported spinosaurid from Asia, it is confidently known only from tooth fossils (example pictured). The type species, Siamosaurus suteethorni (named for Thai palaeontologist Varavudh Suteethorn), was formally described in 1986. In 2009, four teeth from China previously attributed to a pliosaur were provisionally identified as possibly those of Siamosaurus. Siamosaurus's body length is uncertain, but has been estimated at 5.1 to 9.1 metres (17 to 30 feet). The teeth, typically 62.5 millimetres (2.46 inches) long, were conical and had longitudinal grooves and wrinkled enamel. It would have had a long, low snout and robust forelimbs, and possibly a sail down its back. Its teeth are similar to those of other spinosaurids. With teeth suitable for impaling rather than tearing, it may have eaten fish, pterosaurs and small dinosaurs. It lived in a semi-arid habitat of floodplains and rivers. (Full article...)

Today's featured picture
The Consummation of Empire is the third in a series of five oil-on-canvas paintings entitled The Course of Empire, created by the American artist Thomas Cole between 1833 and 1836. The series, now in the collection of the New-York Historical Society, depicts the growth and fall of an imaginary city, situated at the lower end of a river valley. In this painting, the rural village has become a magnificent city, with colonnaded structures reminiscent of ancient Rome. A victorious hero is crossing a bridge in procession and about to pass under a triumphal arch. The architecture and embellishments illustrate that wealth, power, knowledge, and taste have worked together to reach the summit of human achievement and empire. Painting credit: Thomas Cole
