古杯蛇属（学名：Palaeophis）为古杯蛇科（英语：Palaeophiidae）的已灭绝模式属，为水生或半水生的海蛇。生存年代为白垩纪至始新世时期（约7,060~3,390万年前）^[1]，化石发现于英国、法国、丹麦^[2]、摩洛哥^[3]、马利^[4]、美国马里兰州、维吉尼亚州（始新世早期的纳杰莫利组）^[5]、乔治亚州^[6]及密西西比州^[7]。

描述

古杯蛇属物种的体型差异极大，体型最小的Palaeophis casei身长仅1.3米（4.3英尺），而Palaeophis colossaeus，虽然目前仅发现个别的脊椎骨，是本属体型最大的物种，体长可超过9米（29.5英尺）^[4]，为目前已知体型最大的蛇之一。不过大部分的古杯蛇属物种都没有这么巨大的体型^[8]^[9]。

生物学

古杯蛇主要发现于海洋与河口地层，推测为水生动物^[7]，不同种的古杯蛇可能占据有不同的生态位。

研究显示古杯蛇的脊椎骨具有大量的血管分布，代表牠们具有较现代蛇更高的代谢率及生长速率。且代表古杯蛇和其他海生爬虫类（例如沧龙）一样呈内温性^[3]。
