Now hold on a second. There are TWO pterosaur eggs known to science, and they both contain scrambled embryos. No preservation of fuzz, but I don't think fuzz would impress very well on the surrounding sediment. Adults were fuzzy, I'll bet my bottom dollar that babies were, too.

And given the limb proportions of baby pterosaurs, they were probably able to fly right out of the nest, with little to no parental involvement.

I'm so freaking late on this comment. ;-)

Thanks Dinorider! I think I'll go with three babies, with the idea that more could be hatching out of the eggs within the vegetation mound.

Nima - Really interesting stuff man, thanks! I am surprised that the babies/hatchings didn't have "pterosaur fuzz" - should I show them "naked and hairless?"

I think I'm going to abandon the "parents weren't involved in parenting" and have a huge azdarchid mom bringing food to her babies. Thanks for then answers!

Those are a lot of good questions!

Especially at what age baby pterosaurs could fly. They didn't have feathers so they didn't need to "fledge"... though I'd guess their wings took a while to grow proportionally large enough for flight... fitting long-segmented wings in an egg is by no means easy.

Number of babies? No clue. Probably not all that many unless thy parents didn't nest. Sort of like that age-old theory that sauropods didn't build nests and just laid eggs in aimless lines (though they DID build nests, as recent finds in Patagonia showed... and the "egg lines" have mysteriously failed to materialize). I'd say keep it less than seven, for simplicity's sake (and don't forget those poor parents... so many beaks to feed.)

I'm not sure what the babies ate, though it probably wasn't each other. Pteranodon was a fisher, but as for those landlubber Azdarchids.... baby dinosaurs, lizards, mammals, and even snakes were all fair game (the first snakes, if I recall, evolved from lizards during the Cretaceous).

The baby pterosaurs look cute! When I was a kid I used to draw comic strips featuring a pteranodon family that included 3 babies. I had no idea about the number of babies a pteranodon could rise by then.
I have some problems deciding if I prefer the fourth or fifth one, I may want to know which one is scientificaly more "accurate" though.
