I got a question, and this one's a big one. Are there any pics of Mosasaurus conodon's vertebrae out there on the internet or some book that someone conveniently has? It's probably one of the most horrendously photographed genera out there, despite having such in depth descriptions on literally all of its features. Whatever happened to photographing or even drawing these things? |

Were Smilodon's sabers sheathed or exposed? I've read a bit of Nash's take on it having lips and am utterly convinced, but what baffles me is the lack of visible flanges to provide any sort of anchoring point for soft tissue sheathes. |

At this point it's up in the air as both are perfectly plausible. Personally more inclined towards something like an extended lion chin as Nash's lips are much more canine than feline. |

I'm not convinced they'd be covered, but if they were I'd be leaning more towards lower lip pockets as well. Cats tend to use their cheek teeth extensively when eating and enormous cheeks would be a huge obstacle in this regard. Nash's enormous lips would be less disruptive - though still more than necessary - and they'd be very vulnerable to attackers/parasites/infections/what have you. |

Witton does also make a strong case for exposed teeth. |

I was thrown into an existential crisis when I came across this question. It really is difficult to say (too bad that we're only 10,000 years late) but I came to the conclusion that they were probably at least somewhat exposed. The strongest argument I've come across in favor of covered is the enamel hydration hypothesis, but it the evidence isn't cohesive enough to convince me. As for actually protecting the sabers... well, fleshy lips will not do much to stop the mechanical forces acting on the teeth, and anyone who's been hit in the mouth knows that lips smashed against teeth tend to bleed a lot. The big "bulldog jowls" that Nash drew were I think purposely a bit exaggerated, but it's worth mentioning that they would bleed more than usual. Plus there's the issue of fossil evidence. I think it's also worth noting that the sabers would only be exposed in cats with longer canines, specifically dirk-toothed cats like Smilodon and perhaps Megantereon. Scimitar-toothed cats like Homotherium almost certainly would have covered up, because their canines are barely longer than that of a clouded leopard. Posting this was very cathartic.

I too agree with magpie, what may be the only statuette/otherwise human-created image of these cats [if is is a Machairodont, it's Homotherium] then we see covered sabres. That being said too Smilodon 's teeth in particular are incredibly long and I just do not buy the jowl theory either, and the animal's skull shows no sign of a bony sheath as other sabre fanged things do (Gorgonopsids, Thylacosmilus). Allll of this being said, earlier genera [Machairodus] show signs of structurally weak teeth [comparatively, of course] while later genera show structurally stronger teeth [Smilodon], that whole debate being misunderstood. |

Apparently, 26.3m (86.3ft) and 45 tons for G. brancai. |

Thanks. Could you tell me what your source is? And is that length the length of the vertebral column + skull, or the straight-line measurement at rest posture? Edited by Acinonyx Jubatus, Aug 10 2017, 01:46 AM.

I pulled the actual numbers from the description of this pic: https://bricksmashtv.deviantart.com/art/Giraffatitan-brancai-Adult-Skeletal-629732756 But he's since made more. https://bricksmashtv.deviantart.com/art/Giraffatitan-Ultimate-Scaling-669272263 He may use pen and paper, but I swear by this guy's sauropod scaling work. Hopefully the pics themselves should give you a better idea on size than some numbers. For a point of reference, the specimen in the first pic is the largest individual in the chart with a scapula and some restored parts, I think? Both are supposed to be a composite of the two largest specimens HMN XV2 and HMN Fund no 8, which might just be one individual animal anyway. Do with that info as you will.

For its height, I got roughly 52 feet tall assuming the measurements given by DG are in a resting pose. |

Doing some research for a story right now so I have a couple of questions. 1. What would the climate of Iberia have been like around 40,000 years ago? 2. What sort of fauna would have been endemic to Iberia at this time? 3. What would primitive dogs have looked like? What behavior would be expected from them? |

Primitive dogs would best resemble something between a husky and a saluki; thinner build but still "roundness" characteristic of dogs, I'd wager perky ears over floppy ones but wolf-like tail over curled over. Southern mammoths, Auroch*, Reindeer,* Red Deer, Woolly Rhinoceros, Ibex*, Homotherium, Megaloceros, Horses*, your typical on-cave-walls sort of stuff. * are animals you mustn't forget. Something like the plains of Poland, it was colder than today. |
