Hatzegopteryx is the king of this island!

I'm hoping they find an apex preditor on that island doesn't seem like just hatsegopteryx could keep the population in check all on his own you'd think he wouldn't be a permanent resident

That's why many island faunas are called 'unbalanced'. They lack some elements of the faunas found on mainland, simply because they never made it onto the islands. Island faunas don't necessarily have an apex predator: just dwarf herbivores that reproduce slowly.

Its odd to think of the preditor prey relationship not as a rule.

Yeah. :) There are no natural laws in biology. Everything has exceptions, and many of them are on islands. Island faunas are really, really weird.

Speaking of which...what's the weirdest case of island evolution? Not just flightless or giant/dwarf-bizarre, but incredibly bizarre (say unusual breeding cycles)

BTW, there are many cases of unlikely apex predators evolving in islands (terror skink, Haast's eagle, Galapagos giant centipede, Cuban giant owl, etc)

There must have been a bunch of really odd life cycles and breeding habits among island fauna, but it's hard to reconstruct those from the species that are gone. Not the least because islands apparently favour stupidly unefficient breeding on a species level of selection. That is, while more efficient reproduction is inevitable favoured on an individual level (traditional natural selection) the species that end up with too rapidly growing populations tend to go extinct on small islands (species selection). The reason why more species don't go extinct on their own on islands may actually be that natural selection is weak in small populations. In other words, their inability to adapt is the exact reason they survive.

Myotragus, the possibly ectothermic goat, is one of the oddest biologies we know of. Deinogalerix, the huge predatory hedgehog, is also pretty weird. And Nuralagus, the giant rabbit that could not hop. Not to speak of Hoplitomeryx, the tiny deer-like thing that had five horns and giant canines, because less would just not be enough.

FIVE HORNS!?!? 

And shame about Myotragus that we wiped it out. An ectothermic mammal would really be something.

Well, I'm fine with just an giant Azhdarchid as the largest predator, but I heard that there might be fossils of an small abelisaur

Da gibt es leider nicht viel zu erzählen, ich sah die Fossilien vor einigen Jahren in Siegsdorfer Mammutmuseum doch es sind nur ein paar wenige Knochen, zumeist von den Gliedmassen. Das Tier wird dort nur als Hadrosaurier beschrieden und taucht sonst in der wissenschaftlichen Literatur nur ein oder zweimal auf.

Er war auch nicht alzu klein (mit maximal 12m Spannweite)

Allerdings muss sein Design tatsächlich überarbeitet werden, der Hals müsste dicker, und die Propotionen von Körper und Flügeln sind auch nicht ganz korrekt.

Die Größe scheint schon zu stimmen, nur stell ich mir Pterosaurier irgendwie intuitiv kleiner vor. Was ihn sehr beeindruckend macht

I wish that a full feature length 2 and a half hour long movie could be made, that is all about Hațeg Island and the other islands at that time. Just imagine a baby Magyarosaurus trying to avoid those nasty beaks of Hatzegopteryx.
Just imagine a Balaur attacking a hadrosaur. It would be so cool, and we can't go back in time. Oh, we'll.

oh ich seh grad der soll so groß wie ne Giraffe sein, also sind die Sauropoden nur recht winzig^^

Neuere Studien zeigen das er vielleicht etwas kleiner war,"nur" 10 meter Spannweite aber Azhdarchiden konnten in der Tat gigantisch werden und zusammen mit den europäischen Zwergsauropoden wirken sie noch skurieler.

Quetzalcoatlus könnte noch etwas größer gewesen, allerdings lässt sich die tätsächliche Größe schwer abschätzen weil bisher nur sehr wenige einigermaßen vollständige Skelette gefunden wurden.
