Really ? That's strange, the shape of the teeth looked more adapted to catch insects in the first place IMO, I myself would have pointed to the other ones ...

I think you meant raptor like?
it was almost certainly a carnivore

ignore that xD

to me nothing about these teeth points towards any particular diet
they seem rather all purpose

Those teeth are some fancy teeth, I should say xD

If Darwinopterus was a coastal pterosaur, then I'd say the teeth are suited to slippery fish or something.

More inland? I don't know xD

Darwinopterus was an inland pterosaur. It also had no adaptations for fish eating (and neither did most non-pterodactyloid pterosaurs except for Eudimorphodon and rhamphorhynchines, and Qilong/Jaime Headden strongly disagrees with the latter being dedicated piscivores), and had short wings and, as stargatedalek pointed out, generic teeth.

If anything, it was probably like a pterosaurian analogue of a song bird like a robin or a wren.

Wikipedia's Hell Creek entry claims that the discovery of Acheroraptor not only accounts for the dromaeosaurid teeth discovered there before and assigned to Dromaeosaurus, but also to the teeth assigned to Troodon. Except this can't possibly be the case since troodontid teeth look nothing like dromaeosaurid teeth (or so I thought, at least). I know Wikipedia isn't always reliable so I'm thinking it was simple misinformation, but can anyone confirm this for me?

most definitely misinformation

don't trust wikipedia, I gave up trying to edit it to be correct years ago

From my experience it's generally been reliable, but I guess not in this case.

for things like spelling, MYA, and places found its good

but its constantly being bombarded to retrosaur lovers, and so is not reliable on things like anatomy and behavior

this case just seems to be a rather stupid error however :P

Are Gobiconodons hunters or shellfish eaters like Didelphodon?

For the moment, it's more plausible to assume Gobinocodonts were omnivores akin to badgers or opossums. However, new discoveries may change that. Frustratingly, post-cranial remains are almost null.

Would the new studies suggesting mesothermy in dinosaurs apply to pterosaurs as well?

I don't see why not
but I also don't see any guaranteed indication of it (in either dinosaurs or pterosaurs)

I just asked because flying animals tend to be endothermic, but who knows?

insects would like to argue ;)

not to mention the multitude of gliding animals that are exothermic, flying fish, flying dragons, flying squid, hatchet fish...
