Selected article on reptiles

Artist's reconstruction of Waptia fieldensis.
The list of dinosaurs is a comprehensive listing of all genera that have ever been included in the superorder Dinosauria, excluding class Aves (birds, both living and those known only from fossils) and purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomen dubium), or were not formally published (nomen nudum), as well as junior synonyms of more established names, and genera that are no longer considered dinosaurs. Many listed names have been reclassified as everything from birds to crocodilians to petrified wood. The list contains more than 1,000 names considered either valid dinosaur genera or nomina dubia.

Portrait of Mary Anning
Mary Anning (1799 – 1847) was a British fossil collector, dealer, and palaeontologist who became known around the world for important finds she made in Jurassic marine fossil beds in the cliffs along the English Channel at Lyme Regis in the county of Dorset in Southwest England. Her work contributed to fundamental changes in scientific thinking about prehistoric life and the history of the Earth.

Mary Anning searched for fossils in the area's Blue Lias cliffs. Her discoveries included the first ichthyosaur skeleton correctly identified; the first two plesiosaur skeletons found; the first pterosaur skeleton located outside Germany; and important fish fossils. Her observations played a key role in the discovery that coprolites, known as bezoar stones at the time, were fossilised faeces. She also discovered that belemnite fossils contained fossilised ink sacs like those of modern cephalopods.

Anning did not fully participate in the scientific community of 19th-century Britain, who were mostly Anglican gentlemen. She struggled financially for much of her life. Her family was poor, and her father, a cabinetmaker, died when she was eleven. She became well known in geological circles in Britain, Europe, and America. Nonetheless, as a woman, she was not eligible to join the Geological Society of London and she did not always receive full credit for her scientific contributions. After her death in 1847, her unusual life story attracted increasing interest. (see more...)

Selected picture

description

A portrait of the Asian vine snake Ahaetulla prasina. This snake has a wide distribution in Asia, where it occurs in Bangladesh, Bhutan, Brunei, Burma, Cambodia, China, India, Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand, and Vietnam. It feeds on small reptiles and amphibians, particularly lizards and tree frogs. Adults may attain 1.8 m (6 feet) in total length, with a tail 0.6 m (2 feet) long. Its appearance is very much like those of South American vine snakes. It is a rear-fanged species and is mildly venomous but is not considered a threat to humans.
