Gigantophis garstini is an extinct, giant snake which may have measured more than 10 m (32.8 ft), larger than any living species of snake. Before the Paleocene constrictor genus Titanoboa was described from Colombia in 2009, Gigantophis was regarded as the largest snake ever. Gigantophis lived about 40 million years ago in the northern Sahara, where Egypt and Algeria are now located.
