If I remember well, _S. aegypticus_ has been found in the Baharîya Fm.
(mangroves).
What's the paleoenvironment of _S. maroccanus_?

This discussion shows how much it's sometimes difficult to imagine the
behaviour of dinosaurs. Anatomy is very important, but ecology and climat
are also important. What were climat and vegetation like in Albian and
Cenomanian North Africa?
