Giant Ancient Snake Palaeophis Colossaeus Unearthed in Sahara Desert

Fossils often serve as the sole means to understand that a region once possessed a landscape entirely different from its present appearance. Deserts, now dry and barren, can hold remnants of marine life, while mountaintops may contain shells of creatures that once lived at the bottom of the ocean. Through these skeletal remains and rock layers, scientists piece together long-lost ancient environments, including the existence of giant animals that once inhabited them. In the heart of the dry Sahara Desert lies evidence that this area once harbored a completely different world. Millions of years ago, a portion of West Africa was traversed by a shallow sea that served as the habitat for fish, turtles, ancient crocodiles, and an exceptionally large water snake named Palaeophis colossaeus. This ancient snake is estimated to have reached lengths of 8.1 to 12.3 meters, though this highest figure is not based on a complete skeletal measurement. Scientists have derived it from just a few vertebrae, as the known fossils of Palaeophis colossaeus are not yet complete enough to reveal its entire body form. How This Giant Size Was Estimated Palaeophis colossaeus lived during the Eocene epoch, around 56 to 33.9 million years ago, when sea levels were higher and parts of North and West Africa were connected by a body of water known as the Trans-Saharan Seaway. Its fossils were found in shallow marine deposits of the Tamaguelelt Formation in Mali, an area with phosphate layers indicating a productive coastal environment. The species was first described by French paleontologist Jean-Claude Rage in 1983 and belongs to Palaeophiidae, an extinct group of ancient snakes with highly diverse body sizes. In 2018, a team of researchers...
