Eurazhdarcho: a nightstalker?

Every new azhdarchid make the day a bit like christmas for me =) This new giant, Eurazhdarcho was found in Romania and is one of the smaller species (3m wingspan). But more interesting for me is that at the same time and at the same place another azhdarchid rule the land (and sky) Hatzegopteryx was on the other end of the size spectrum; a giant beast, tall as a giraffe, with 11 meters wingspan.
And they were not alone, in north america and it's the same thing: small azhdarchids and big life together (In asia maybe too, I believe I heard that asia had some footprints of giant pterosaurs...).
The questions are: why? and how?
How could such animals which are very similar- the beaks of small and big azhdarchids differ not much and the same holds for the body plan- live together. They could have hunt prey of a different size- Hatzegopteryx could hunt even middle sized dinosaurs- but I want to show here another possibility of how they could coexist.
I notice that some smaller herons are nocturnal or crepuscular (night heron or boat-billed heron etc.), big species instead are mostly diurnal (grey heron, great egret etc.). These animals aren't specialized on that daytime, some are actual very variable, but they have a daytime they prefer.
I imagine that smaller azhdarchids might have had a similar livestyle. Bigger azhdarchids, like Hatzegopteryx and Quetzalcoatlus, would have hunt big diurnal prey and the smaller species feet the small mostly nocturnal/crepuscular prey, like mammals and amphibians.

Well, I'm curious what you think about that =)


Edit: Sorry for the quality, I was a bit fast :blushes:

I have only starting looking at pterosaur art it is amazing, a level of fine beauty no dinosaur or living animal could ever achieve. Fight me lol.

I like how you design it to be very drak and scary, but also animal like, brilliant sir.

I think they are gorgeous even though they are a bit weird. Nice art!

I'd safely bet that these were some of the scariest creatures of the Mesozoic.

This is the most amazing piece of paleoart I have ever seen

Besides the fact, that it's beyond amazing, what's the probability that a prehistoric scene like the one on National Geographic occured, where a giraffe was surrounded by hungry lions, only this time with this guy and a pack of dromaeosaurs for example?

Thanks =)

Well, that could be, we at least know of one case were dromaosaurs have eaten a azhdarchid, but we
don't know if the giant was killed by these small killers =)

Thanks for answering! This makes you wonder what sort of brutal events happened in the dinosaur world and how we, humans, unfortunately have missed them. But thanks to your and other amazing paleoartists we can once again take a glimpse into that strange and distant world!:D (Big Grin)  
I asked you about that scenario (the one with the giraffe and lions on Nat Geo) because I found it very spectacular (and also frightening) and immediately thought of replacing the giraffe with a giraffe-sized azhdarchid and the lions with a pack of "raptors". I'm sure that its beak would have been lethal, but who knows, maybe if cornered it could have not been able to take off...?
All these things aside, your paleoart is as lively and amasing as the dinosaurs once were, so keep the good work!!!Dance! Dance! Dance! Dance!

Imagine waking up at 3:00 in the morning and seeing this in the corner of your room. Creepy huh?

In the corner of your room, standing completely motionless, like a statue, but pretty much alive!!
