记述了贵州兴义法郎组竹杆坡段(中三叠世拉丁期)长颈龙属未定种(Tanystropheus sp.)一幼年个体的不完整骨架。这是该属在欧洲和中东以外的首次发现。新材料仅保存部分颈椎、躯干和前肢。根据特殊的颈椎形态将该标本归入长颈龙属,而区别于另一种长颈的海生原龙类———东方恐头龙(Dinocephalosaurus orientalis)。新标本的腕骨形态简单,骨化程度弱,表明长颈龙是终生水生的动物。“长颈、长颈肋”见于多种不同海生爬行动物(如原龙类、初龙类),它们很可能都以“吞吸”的方式捕食。长颈龙化石在我国的发现进一步验证了中国南方三叠纪海生爬行动物群与欧洲西特提斯动物群(western Tethyan fauna)之间的密切关系。
The incomplete skeleton of Tanystropheus sp., A young individual, is described in the Zhupanpo section of the Xingyi Franc Formation (Middle Triassic Latin). This is the first discovery of this genus outside Europe and the Middle East. The new material holds only part of the cervical spine, trunk and forelimb. According to the special form of cervical vertebrae, the specimen is classified as dinosaur, which is different from dinosaur dragon dinosaur (Dinocephalosaurus orientalis), another long-necked marine dragon. The carpal bones of the new specimen are simple in shape and weakly ossified, indicating that the long-necked dragon is a lifelong aquatic animal. “Long-necked, long-necked ribs” are found in many different marine reptiles (such as the original dragon, dragon class), they are likely to all “swallow” way to prey. The discovery of long-necked dragon fossils further confirmed the close relationship between Triassic marine reptiles in southern China and the western Tethyan fauna.
