Egypt fossils reveal new extinct crocodile species

An international team of researchers has identified a new extinct species of crocodile, named Herugavialis cairensis, from fossils found in the limestone of Egypt's Mokattam Formation. This geological layer provided the stone used to construct the Great Sphinx of Giza.

The discovery, published in Royal Society Open Science, stems from a re-examination of fossils originally collected in the 1920s. For nearly a century, the specimens were misidentified as belonging to the genus Tomistoma. However, modern paleontological techniques, including CT scans, revealed distinct anatomical features, such as an elevated ridge around the eyes, that necessitate a new genus.

The species lived approximately 45 million years ago during the Middle Eocene in shallow marine environments. Researchers noted a striking physical coincidence: the fossilized skull is missing the tip of its snout, mirroring the missing nose of the Great Sphinx. This resemblance inspired the name Herugavialis, derived from the Egyptian god Heru (Horus). The new species belongs to the gharial group, characterized by long, slender snouts adapted for catching small fish.
