To be fair, it wasn't that they were different. They were absent. Compare the skull of Macrauchenia: https://www.gastondesign.com/store/images/uploads/macrauchenia-skull.jpg To that of a tapir: http://www.boneroom.com/uploads/4/8/1/1/48118243/s521972503441136676_p1269_i1_w338.jpeg Or the saiga antelople: http://www.izw-berlin.de/tl_files/images/Services/Skull%20of%20a%20male%20saiga.%20Photo%20R.%20Frey.jpg Or the elephant seal: https://upload.wikimedia.org/wikipedia/commons/4/4c/Northern_Elephant_Seal_Skull.jpg It's weird that the biggest and most iconic examples, the elephants, do things backwards, with most of their muscle support being that broad bit under the nasal openings: http://www.skullsunlimited.com/userfiles/image/variants_large_2967.jpg Even then, there's still muscle support across the face. Macrauchenia seems to lack anything of the sort, hence why the presence of a trunk in that genus has been pulled into question. Honestly it's shaping up to be a mimic of everybody's favourite mainstream group of Jurassic sauropods, the diplodocids: https://upload.wikimedia.org/wikipedia/commons/4/42/Kaatedocus_skull.png Viavenator was a brachyrostran, like Carnotaurus itself, and unlike Majungasaurus. Simple enough question. Edited by Incinerox, Mar 24 2016, 05:05 PM.

I've been on a hunt for information about the Alaskan therizinosaurus footprint, so far from what I've been able to gather the footprint is from the Cantwell Formation dating around 70 MYA meaning it likely coincided with some of the Prince Creek formation's fauna. however I cannot find any information on the size of the prints. does anyone know how large these prints are? |

Not only can I tell you that it's 23.1cm long, I can give you the paper itself: [Linky link] Edited by Incinerox, Mar 26 2016, 03:48 AM.

Based on tracks being about 9 inches (cause I'm American) I'd would think that it was no bigger then 15 feet, 20 feet at max. Based on information from other theropods. |

I have a Question: The andrewsarchus, was not found more fossils, because so far what appears on wikipedia is only found a skull from his hallmark discovery. |

I think he means to say whether Andrewsarchus has more remains already found, which sadly there are none of, even until now... |

Estimates range from 1000-3300 pounds or for you metric users 455-1500 KG EDIT: So I saw this piece of art by Paleop and I was curious, what is the evidence for those spikes underneath the neck of the brontosaurus?

I was wondering the same, as that is not the only place I've seen those. |

Something about the prong-like bones protruding from the bottom of the neck vertebrae IIRC, though don't quote me on that. |

brontosmash let me summarize: the necks of apatosaurines were thickly muscled and likely had bony protrusions (bosses). the spikes are a speculative expansion of the brontosmash. also side note; I forgot to scale the stego at the time this was released, I will update that soon. |

What are the best references to use for Concavenator? With the absence of our savoir Scott Hartman I've picked these images (I know atrox's has a shrinkwrapped skull).![]() ![]()
