The paper in question found that the skull of Sarcosuchus would be "suffering very large shear stress" if it tried to deathroll. This was based on its value on their 'death roll capability indicator' (DRCI), which came out as between that of gharials and false gharials, neither of which perform deathrolls. However, it's worth noting that while all the narrow-snouted species they examined seemed to have primarily fed on fish, most of them (excluding gharials of course) were still fairly generalist, taking prey items they could swallow without much need for dismembering. Taking the massive size of the skull of Sarcosuchus into account, it would still probably be capable of taking fairly sizeable terrestrial animals. False gharials in particular, which had the closest DRCI value to Sarcosuchus in the study (I think), are known to prey on larger vertebrates, including an account of one attacking a cow, and at least three fatal attacks on humans, so the low DRCI evidently doesn't preclude preying on larger prey. tl;dr: Sarcosuchus probably couldn't deathroll, it probably ate a lot of (big) fish, but it would be capable of a generalist diet that would exclude relatively large (i.e. giant) prey items. |

That makes sense I guess. I wonder if deathrolls capacity was ever tested for champsosaurs or phytosaurs. The former in particular would be interesting to note, since they have proportionally gigantic jaw muscles in spite of their thin snouts. |

I have heard people talking about Siats being pulled into Megaraptora or something like that. Any information on or opinion this? |

None from me. It's still up in the air given that no one has tested Siats' cladistic placement properly since Megaraptora moved to tyrannosauroidea. |

yet another oddball question: which creature would be best against a pack of beowolves from RWBY: erythrosuchus, titanophoenus, inostrancevia, or anteosaurus? |

Beowulves' strength is in their speed and agility. From the list your provided, Inostrancevia seems best adapted to counter that advantage. |

ZT2-related questions, what scale and biome fit for:
A real-life question, what is the tallest dinosaur to be ever discovered? And, is Breviparopus is real, I mean, something that are non-nomen-dubium? |

Traditionally Sauroposeidon has been regarded as tallest, but I'm going to guess Barosaurus or a similar genus has it beat. It's neck alone was longer than Giraffatitan was tall. Of course, habitual posture would affect it's actual height, but I'm not sure at what angle Diplodocoids usually held their necks at. Breviparopus definitely exists. I think I read that its size was way overblown though because the people who described it didn't account for the spreading of the tracks or something like that. |

Barosaurus (if i did the math right) isn't as gigantic, as Giraffatitan is only around 40 feet tall really. Barosaurus would probably be around the same length in the ballpark as Diplodocus really. at best probably only 130 feet as i only used 40ft for the size of the neck, but it's probably more of 45 for the neck. Anyways. From what I remember Diplodocoids usually held their necks somewhat parallel with the ground. ![]() Barosaurus 40ft neck(Red) scaled next to Puertasaurus(Blue) both silhouettes are used from Scott Hartman's skeletals. |

They reassigned a Supersaurus neck vertebra to Barosaurus, which means Barosaurus' neck could grow up to 17 meters- ten feet longer than your restoration. And I thought the whole "horizontal neck" thing had been debunked a while ago?

I can't speak for most of these, but I think it would be reasonable to assume that Mediterranean Scrub would best suit the Dwarf Sicilian Elephant. If you want a non-AD biome, maybe scrub? |

I don't know about neck vertebrae could support horizontal gait or not, but wasn't Diplodocoid's pegged teeth more suitable to feed on fern or smaller, softer branch which they can strip their leaves off. These plants are also found normally on ground or lower level of canopy, so the horizontal gait sound more reasonable as the animal doesn't need to spend much energy trying bend it neck down to feed. Meanwhile, Macronarians which have more robust teeth can easier browse on thick conifer branch or something like that and they become the tree top feeder while Diplodocoids graze on lower level. Don't take my word though, it could be wrong. |

Diplodocids were specifically designed for rearing, I doubt they were feeding exclusively on ground foliage. |

So what's the deal with Aegirocassis and the Anomalocaridids? Did they all have two rows of fins? |
