The Bahariya formation contains a very diverse ichthyo-fauna but also aquatic and semiaquatic reptiles are also known, crocodiles are the better known part, plesiosaurs the lesser. Stromer described once Peyerus capensis, but later reviews showed that it was actually a junior synonym of Leptocleidus.
Leptocleidus was a very small plesiosaur/pliosaur (the taxonomy seems to be uncertain) with 3 m in length and Leptocleidus superstes reached only 1,5 m. Leptocleidus is known from freshwater and brackish water habitats so it's not surprising to find remains of this genus in the western desert which is known to contain a former river and mangrove system.
Unfortunately this was also the realm of... who knows it? Who knows it? 

Right!

Spinosaurus!

(ok now it become silly)

Edit: how it turned out Leptocleidus capensis wasn't present in the Bahariya Formation, instead the Stromer material seems to belong to an polycotylid.

Very nice work! You wouldn't happen to know of any large South American Pliosaurs would you? I used to think of brachauchenius as the large South American Pliosaur, but that has been debunked recently. For some reason, I have some strange obsession with finding a large fresh water Pliosaur that hunted Titanosaurs (I.e. Saltosaurus) like how crocs hunt wildebeest in Africa. I know it's stupid and farfetched, but I like the idea of another predator competing with Abelisaurs over the Sauropods.

When you look for competition for a titanosaur meal you should look at crocodylomorphs like large baurisuchids.

The largest pliosaur of which I know is a fairly complete Kronosaurus, but these aren't giants like their australian
relatives.

It would suck to be chased by that!

Well, plesiosaurs were certainly better swimmers than humans but it's implausible that a Leptocleidus would see you as prey.

I know, but the real problem is, are they territorial?
Dominant?

We will never know, but I think it's relatively save to assume that they were not territorial, like most open sea- or coastal water-creatures from modern times.

I was thinking that too, but like a shark, if you get too close it might trigger a defense. (or it may mistake you for a meal)

Geez-how many predators can you fit into mid-Cretaceous North Africa?
Hyrotrioskjan's avatar
HyrotrioskjanProfessional General Artist
Many more...

Apperently the predators formed 90% of the biomass and the ecosystem was an aquatic one (where, without human interference, such cases are common). There was a high amount of predator-predator interactions and predation, with everything eating everything else.

I know, reminds me more and more of the Dimetrodon ecosystem from Texas...
acepredator's avatar
Or the Miocene South American ecosystems (seriously why would you have the biggest croc, biggest turtle, biggest terror bird, second biggest snake and biggest shark in or around the same place at the same time?)

I thought especially about the Dimetrodon because of the sail ^^ but the Titanoboa ecosystem is also a good comparison.
acepredator's avatar
That too, But I was talking about the Miocene.

a modern reef will also have a very large number of predators without human interference.
