Tanystropheus

Tanystropheus (Greek τανυ~ “long” + στροφευς “hinged”), was a 20 foot long reptile that dated from the Middle to Late Triassic epochs. It is recognizable by its extremely elongated neck, which measured nearly 10 feet long—longer than its body and tail combined. The neck was composed of 12–13 extremely elongated vertebrae. With its very long but relatively stiff neck, Tanystropheus has been often proposed and reconstructed as an aquatic or semi-aquatic reptile, a theory supported by the fact that the creature is most commonly found in semi-aquatic fossil sites wherein known terrestrial reptile remains are scarce. Fossils have been found in Europe. Complete skeletons of small individuals are common in the Besano Formation at Monte San Giorgio in Italy and Switzerland; other fossils have been found in the Middle East and China, dating from the Middle Triassic to the early part of the Late Triassic (Anisian, Ladinian, and Carnian stages).
