INFO ? Gill Man autopsy
Once surgery began it became clear this is no alien, but an Earth born creature, an ancient pre-historic race that was thought destroyed at the very moment mammals became dominant. In a time when dinosaurs roamed these creatures lived, the Gillmen- amphibious, intelligent and strong. The cataclysm that ended the reptile rule on this planet forced these creatures into a symbiotic relationship with the newly arrived aliens. A small electronic device is lodged in the skulls of the creatures.
