Sorry, I was under the impression that more complete skeletal remains were known. And I guess the fact that it's of the same family as the aquatic Mahajangasuchus may provide compelling evidence against the terrestrial hypothesis.

I suggest to look at Wiki instead of Carnivoraforum. More reliable due to larger amount of competent users and being more of an encyclopedia than monsterfight fanclub.

I remember reading some time back about Hesperornite-like remains from Hell Creek or another formation from the same time, can anyone give me more detail about this one ?

Is this the one you're after?

I think it's that one.
Do we know if it was a marine or inland species ?
As far as i remember, the Lance Formation was a coastal environment, but I am not sure.

I saw no clues on that. But I'd guess it was capable of surviving in marine and freshwater surroundings, if it is indeed found in HC rocks.

I was planning to give kaprosuchus a PRIMARLY terrestial living and hunting style but sit will still seek the safety of the waters in dangerous situation

Almost all crocs will seek safety in water, even Pristichampsus (so I assume, at least).

Mesozoic crocodylomorphs were not necessarily tied to aquatic environments, as a very large variety of species were fully terrestrial animals. Crocodilians developed semi-aquatic habits multiple times, they weren't basically aquatic animals.

Even Cenozoic crocodiles assumed completly terrestrial habits when given the chance, as pristichampsids and mekosuchines show. These animals even developed hoof-like claws for crying out loud.

The member I quoted is one I find trustworthy, being a competent person who reads scientific studies and such. While it's teeth and lower jaw structure show that Kaprosuchus had a different killing style than modern semi-aquatic crocodiles (AKA all extant crocodiles), they are not proof that it was a highly terrestrial one. IMO, Kaprosuchus was still more terrestrial then modern crocs, but not nearly to the degree of animals like Baurusuchus and Sebecus

And I'll be eager to accept it as an aquatic animal as soon as there are hints found suggesting such lifestyle in the fossil. If the skull anatomy speaks "terrestrial", logical conclusion is to lean towards the suggested thing rather than say something contradictory (I assume it's something akin to 'think outside the box' but disregarding present evidence needs to throw it away, you need better proof for the opposite).

Family relationships give animals their general appearance and/or behavioural adaptations, but as proven with other archosaur families, being related doesn't mean being the same. If Kaprosuchus indeed shared overall body proportions with its relative Mahajangasuchus, then it would not be that much different in adaptations for moving on land from its more distant relatives like Theriosuchus. The long-legged Sebecosuchians aren't the only land-dwelling croc examples, so relating to their morphology isn't necessary here.

I'm not saying it is aquatic, I'm saying that based on skull shape it probably was somewhere in between modern crocs and fully terrestrial crocs. Regardless, like with practically every extinct species that is mildly interesting, more fossil evidence is needed.

Would a couple species of moa and adzebills coexist peacefully if they were in a zoo setting?

Why... why must this thing exist? Why must it haunt my nightmares?
I may sound like a total moron saying this, but could someone try to explain that article for me? I can't understand anything with all that fancy talk. From what i can gather, this thing can split it's jaw open? is that it?

its upper jaw is just that Lovecraftianly shaped... Which allows it to split its upper jaw open... It is quite creepy...
@Adm Gen Aladeen: well not much exhibits IRL mix ratites, so I doubt they would fit well in one exhibit... But them again, in real life, their range do overlap so you have good precedence to put them together...
