It's to small in this view...

What about Pyroraptor? Didn't it live here, too?

Hi Hyrotrioskjan,
Is your picture copy-righted? May I use it in my teaching or writing?

How about Tarascosaurus? How big would he be?
👍: 1 ⏩: 1
BTW Tarascosaurus was (supposedly, from what I should tell) a type of abelisaur. He was on Dinosaur Planet (2003) on the episode Pod's Travels, where he coexisted with Pyroraptor, Rhabdodon, Ampelosaurus (on the old island, which I could very well be wrong about; it might've been Magyarosaurus on both), Magyarosaurus (of course)), Elopteryx, and the crocodilian Allodaposuchus.

The hatzegopteryx neck is a bit shorter but still very nice.

This Hatzy was done long before Witton and other realized that, here some more recent sketches: www.deviantart.com/art/Short-n…

Okay then. Sorry. Well maybe an updated version?

When I will update this I will do the whole series, but not now

Wow those sauropods look so small compared to the quetzalcoatlus. Its scary and awesome to think about it a flying lizard the size of a giraffe!

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.

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

Hopefully they can name and identify it

Is this showcasing an example of island dwarfism?
👍: 0 ⏩: 1
Yes, many of these species are smaller than their mainland relatives

Ein Hadrosaurier aus Bayern? Hättest du dazu ein nähere Infos?
👍: 0 ⏩: 1
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.

Imagine been stalked by that massive Pterosaur in very thick and tall grass it would be terrifying

Der Hatzegopteryx erscheint mir ziemlich riesig O.o

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

People say that Rodan is a Giant Pterosaur I usually Believed that He was a Giant Teranodon.

I think you mean Pteranodon, which is a pterosaur
