Psittacosaurus is a genus of psittacosaurid ceratopsian dinosaur from the Early Cretaceous Period of what is now Asia, about 130 to 100 million years ago. It is notable for being the most species-rich dinosaur genus. Nine to eleven species are recognized from fossils found in different regions of modern-day China, Mongolia and Russia, with a possible additional species from Thailand. All species of Psittacosaurus were gazelle-sized bipedal herbivores characterized by a high, powerful beak on the upper jaw. At least one species had long, quill-like structures on its tail and lower back, possibly serving a display function. Psittacosaurus is not as familiar to the general public as its distant relative Triceratops but it is one of the most completely known dinosaur genera. Fossils of over 400 individuals have been collected so far, including many complete skeletons. Most different age classes are represented, from hatchling through to adult, which has allowed several detailed studies of Psittacosaurus growth rates and reproductive biology. The abundance of this dinosaur in the fossil record has led to establishing the Psittacosaurus biochron for the Early Cretaceous of east Asia. (Full article...)

    File:Ayrton Senna Imola 1989 Cropped.jpg, the last driver to be killed during a Grand Prix weekend]]

    Forty-nine drivers have suffered fatal accidents while driving Formula One cars since the creation of the Formula One World Championship in 1950. Thirty-two of the drivers died during World Championship Grand Prix race weekends, six during test sessions and eleven during non-championship Formula One events. The Indianapolis Motor Speedway has seen the most fatalities; seven drivers have died there during the course of the Indianapolis 500. Fifteen drivers died in the 1950s; fourteen in the 1960s; twelve in the 1970s; four in the 1980s and two in the 1990s. No driver has suffered a fatal accident since 1994, making this the longest period in F1 history without a driver fatality. Only two Formula One Champions have died while racing or practicing in Formula One, Jochen Rindt in 1970, and Ayrton Senna (pictured) in 1994. Rindt is the only driver to win the championship posthumously. (Full list...)

    The Frecce Tricolori is the aerobatic demonstration team of the Italian Aeronautica Militare, based at Rivolto Air Force Base, in the Friuli Venezia Giulia region, province of Udine. They were formed in 1961 as an Air Force team, replacing unofficial teams that had been sponsored by various commands by the end of the 1920s.
