Tanystropheus (SciiFii)

Tanystropheus (Greek τανυ~ “long” + στροφευς “hinged”), was a 6-meter-long (20 ft) reptile that dated from the Middle Triassic period. It is recognizable by its extremely elongated neck, which measured 3 m (9.8 ft) long—longer than its body and tail combined. The neck was composed of 12–13 extremely elongated vertebrae.[1] 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 juvenile individuals are most abundant in the Besano Formation of Italy; other fossils have been found in the Middle East and China, dating to 232 million years ago during the middle Triassicperiod (Ladinian stage).[2]
