Scientists have identified an extinct crocodilian from a 45-million-year-old rock layer in Cairo, the very stone used by the ancient Egyptians to build the Great Sphinx. Remarkably, this prehistoric reptile’s fossil skull displays a missing snout tip, echoing the famous Egyptian monument's own missing nose.
- Fossilized crocodilian discovered in the Mokattam Formation, Cairo
- Skull missing the snout tip, mirroring the Sphinx’s missing nose
- Species renamed Herugavialis cairensis after detailed CT scans
What happened
In the 1920s, fossils were excavated from the Mokattam Formation in Egypt, a geological layer famously quarried by the ancient Egyptians to construct the Great Sphinx. For decades, these fossils, including an almost complete skull, were thought to belong to a type of gavial crocodile known as Tomistoma, previously known only from Southeast Asia.
Recent advances in paleontology, especially high-resolution CT scanning, have allowed scientists to examine the internal structure of the skull in unprecedented detail. These analyses revealed significant differences from the Indonesian and Malaysian Tomistoma species, leading to the classification of a brand new species named Herugavialis cairensis, honoring both the Egyptian god Heru and the city of Cairo.
Why it feels good
This discovery offers a fascinating glimpse into Egypt's prehistoric ecosystem and its connections to iconic cultural landmarks. The fact that the fossil crocodilian's skull is missing its snout tip, much like the Great Sphinx's famous missing nose, creates a compelling and poetic link between natural history and human heritage.
Additionally, uncovering a new species highlights the dynamic diversity of crocodilians that thrived in shallow marine environments around the Mediterranean region for millions of years. It reminds us of the ever-evolving story of life on Earth and the importance of scientific tools that continue to unlock secrets from the distant past.
What to enjoy or watch next
The study, published in Royal Society Open Science, invites further exploration into the variety of extinct crocodilians once widespread around the Mediterranean and Nile regions. For those intrigued by paleontology, upcoming research may reveal more about how climate changes and sea level shifts affected crocodilian diversity through geological time.
Fans of Egyptology and natural history alike may enjoy observing how modern technology like CT scanning continues to reshape our understanding of ancient creatures that shared the landscapes beloved by the builders of Egypt’s timeless monuments.
