In the Cretaceous Period (c.100 million years ago) Egypt and North Africa were radically different environments. With vast tidal flats and mangroves, and a shallow sea, the continent fostered numerous animal and plant species. Creatures like Paralititan (sauropods); the sprinting Deltadromeus; the infamous Spinosaurus; and the newcomer Tameryraptor. These have been preserved in the fossil record from Egypt and other countries in North Africa. Today, we meet some of the inhabitants of this ancient landscape… Logo image: Spinosaurus aegyptiacus, by Paleogeeksquared, via Wikimedia.
