贵州龙生活在距今2.1亿年前中三叠纪,它小脑袋、长脖子,身体宽扁,很像后来出现的蛇颈龙。它四肢仍保留趾爪,能像鳄鱼一样匍匐前行。它大部分时间生活在水里,宽大的脚掌及细长的尾巴很适于在水中游泳,喜欢吃鱼及小型水生动物。
The Guizhou dragon lived in the Middle Triassic 210 million years ago. It had a small head and long neck, and its body was wide and flat. It resembled the plesiosaur that appeared later. It still has claws on all fours and can walk like a crocodile. It spends most of its life in the water. Its large feet and slender tail are ideal for swimming in the water. They like to eat fish and small aquatic animals.
