Gigantophis garstini, the first and largest described madtsoiid, was recovered from the upper Eocene of Fayum, Egypt.Gigantophis garstini, for example, was a hefty beast that slithered around about 40 million years ago on a body that researchers estimate was anywhere between 23 and 32 feet (7 - 10 m) long, according to a PLOS blog post. Madtsoiidae is a speciose family of extinct snakes that achieved a wide Gondwanan and trans-Tethyan distribution by the Late Cretaceous, surviving until the late Pleistocene.
