Palaeophis ('ancient snake') is a prehistoric genus of marine snakes. Palaeophis colossaeus from the Paleogene Trans-Saharan Seaway deposits of Mali was one of the largest snake ever, reaching the estimated length af about 9 m (30 ft), about as long as the the previous record holder of the largest snake Gigantophis. . This puts the genus in the running for one of the largest snakes of all time behind titanoboa. other species where not as large with, P. casei ', being the smallest at 1.6 meters,.[1]


Palaeophis colossaeus is one of the largest snake discovered while palaeophis casai was the smallest of the genus discovered reaching a size of 1.3 meters.p.maghrebianus may have also reached larger size's based on new discovery


palaeophis species thrived when earth was on a warmer phase they where adapted to a aquatic lifestyle with fossils found on sediments of marine and estuaries
