Leptocleidus capensis by Hyrotrioskjan Leptocleidus capensis by Hyrotrioskjan
The NEW picture: hyrotrioskjan.deviantart.com/a…
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.

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)

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.

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.

That too, But I was talking about the Miocene.

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

Okay....well....considering that I am a fan of black theropods as a whole...what do you think, by the way, about the new reconstruction of Spinosaurus as per Sereno? I like the idea of a hippo-like lifestyle, maybe walking on the river bottom while hunting

I like that new look, I will wait for the paper but it seems like a very fitting morphology for a animal in such a environment (and I like it because all the JP fanboys have now no longer to argue about who would win a fight in an Spino vs. T. rex battle, they just wouldn't fight ;)

Ah, science, you beautiful, beautiful person! Now that hippo Spinosaurus is out of the picture, all Tyrannosaurus has to do is go up against large carnosaurs and for the more creative and more intelligent "DINOSAURSAREMONSTERKILLERSWITHATASTEFORBLOOOOOOOD!!!!!!!!" fans, T. rex vs Therizinosaurus :)

but one thing, I really hate those fanboys. Like I tried explaining to a fanboy who added me on Facebook, Spinosaurus would have absolutely zero reason to fight a terrestrial apex predator, not even in its own homeland, even under the older model. IT still is a hippo/crocodile thing there.

Yes, Jurassic Fightclub and Co. are even worse than Jurassic Park in my eyes, JP no longer tries to be scientific and most people are aware of that but these "documentaries" create scenarios like those JP-fanboys, make everything AWESOME and turn normal animals into killer machines... and than tell you "that's scientific fact" :puke:
