Do we know any definitive diet for Purlovia? Didn't know whether the ARK wiki was correct that it was an herbivore (even though it's set to be a carnivore in-game).

With this recent news about the super long neck of Barosaurus is it possible it had a longest dinosaur neck? Longer then the one(s) of Mammechisaurus?

Proportionally, I seriously doubt it, though IIRC Supersaurus had the longest neck known from any Sauropod, at least known from good remains.

Super giant Barosaurus' neck next to Giraffatitan


I don't know, looks pretty huge to me

Actually, that huge Supersaurus neck vertebra you're referencing got reassigned to Barosaurus. That's where these huge new estimates are coming from. https://svpow.com/2016/09/16/how-horrifying-was-the-neck-of-barosaurus/

So Mosasaurs...just for the sake of curiosity why/how did they die off? I mean sharks and crocodiles lived during the same era and have long surpassed the K/PG extinction and even had some of the same niches so why not some mosasaurs? Why couldn't they survive past this point?

I can see why massive species like Tylosaurus and Mosasaurus didn't but how come some of the smaller and freshwater species didn't survive?

I think you guys missed the part where Flish used the word "proportionally". Even if Barosaurus had a huge neck, proportionally it has nothing on the Mamenchisauridae.

As for mosasaurs, probably just by chance. A lot of species died off where others in similar niches didn't.

Just a personal guess, but IMO sharks probably outlived Mosasaurs because they could retire to deeper waters to escape the changes inducted by the cataclism, something an air breathing animal couldn't do.
Crocodiles and other aquatic reptiles had a slower methabolism, so that might have given them the advantage in the long run; they could probably last longer without food, perhaps in prolonged hybernation or similar conditions, while Mosasaurs couldn't eat enough.

Also worth noting that so far we know only one cnfirmed freshwater mosasaur. It's possible they weren't that common (you'd probably need a vast and rich environment to support them) and this played a role in their demise.

Large marine tetrapods tend to be the first to die off when shit hits the fan, so no surprise to anyone even vaguely familiar about how ecology works.

And sharks didn't pass the KT event unscathed eithr

Does anybody have a link or article describing how sarcosuchus couldn't have used the deathroll and primarily ate fish?

I don't see why lack of a deathroll and piscivory need to be connected, the deathroll is in modern crocodilians as much a method for rapid eating due to intraspecific competition as it is a killing method.

I was told by someone that it's skull wasn't not designed to perform in such a way and it may have eaten primarily fish

I believe it was Incinerox who said so...

Sarcosuchus is peculiar. It's skull is not built like other crocodiles- it almost looks like a gharial on steroids. It's jaws almost remind me of a spoonbill's, if a spoonbill had armor-piercing teeth and a ridiculous overbite... Plus, what's up with that nasal cavity? I do not believe this critter was doing the same thing as modern crocodiles OR gharials.

I don't specifically see why it would be unable to deathroll, but I could be wrong. It was a large fish specialist nonetheless, which would make deathrolls not particularly useful, even when attacking bus-sized coelacanths

Perhaps a thin snout wouldn't be able to sustain the forces involved in the death roll.
