Gigantophis
Gigantophis garstini was an extinct giant snake. Before the Paleocene constrictor genus Titanoboa was described from Colombia in 2009, Gigantophis was  the largest snake ever recorded. Gigantophis lived about 40 million years ago during the Eocene, in the Paratethys Sea. This was in what is now the northern Sahara, where Egypt and Algeria are now.
