Spinosaurus neotype from the discord  So about 10-10.2Ms. What would MSMN-047's length be? MSMN is now 14.4 meters long. |

Oh, but just to clarify, there is supposedly a big ass biepdal proto sauropod right? If so, how likely do you think it gets downsized like amphicoelias was?

Yes there is ( link->). Looking at the methodology, I think it's possible it could be downsized in the future, but it doesn't seem to be a horrible method for extrapolating size to me. I'm personally comfortable taking it at least for now, but someone like theropod probably knows more. As for Amphicoelias, first thing you might want to know is that the species you're referring to, A. fragillimus, is now called Maraapunisaurus fragillimus. And second, to be fair, its exact size is still a matter of discussion. Recently Greg Paul published a paper where he estimated it at anywhere between ~80-120 tonnes, even accounting for its revised phylogenetic affinities (as a basal diplodocoid) ( Paul, 2019). And he used volumetric methods to obtain this size estimate. |

I could have sworn I posted this earlier, but using the search function, it doesn't look like I did. Anyway, here's the skull of Janjucetus (a toothy, macropredatory mysticete) compared to that of a lion.  Image source-> |

Great auk skull compared to that of its closest living relative, the razorbill. Great auk is obviously the bigger one.  Image source->EDIT: and taxidermied specimens.  Image source-> |

Franoys more current Sue skeletal (Note Fran has stated when it comes to Scotty add 300 kg to 500 kg more for Scotty this is a rough estimate but it is similar to the results from Persons et al)  |

Teeth of the three (main) different types of Northern Hemisphere orca ( image source->).  From left to right: transient (an obviously worn example), resident, and offshore. I had no idea they were this different, especially in robustness, until today (although, I knew there were differences in cross section->). I know that there has been talk going far back as to whether or not O. orca should be split into different species or subspecies. What's become of that? |

Skeletons of an Asian elephant and a southern elephant seal. Obviously the anterior half of the seal is closer to the camera than the elephant is, but you can still get a sense of scale, as the other half of the seal is underneath the elephant's tusks.  Image source-> |

The ulna of a modern African elephant compared to that of a mastodon.  Image source->Another version of an African elephant's femur compared to that of Triceratops. The elephant's femur seems to be settled on a higher platform (I don't know how much the plaster jacket elevates the Trike femur, though), but either way, you can see a clear difference in thickness of the diaphyses.
