According to renowned researcher Dr Per Christiansen, the cave lion had relatively stronger Forelimbs and broader chests than modern lions,tigers and clouded leopards : Given that cave lions were stronger than tigers in the forelimbs and chests, it seems plausible to argue that mosbach lions were stronger than Ngandong tigers since Panthera fossilis was basically a beefier version of Panthera spelaea whereas Ngandong tigers wouldn't have been particularly strong compared to modern tigers on a porportional basis as shown here : foodchaingang.proboards.com/post/15736/thread/1498 |

Relative humerus robusticity comparison between Smilodon Populator and Xenosmilus Hodsonae ! HRI : It is humerus mediolateral diameter at mid-shaft/humerus length.Robust forelimb bones protect the animal from violent stresses during grappling. S.Populator : 11% X.Hodsonae : 10% Edge : S.Populator HRI2 : It is humerus anteroposterior diameter at mid-shaft/humerus length. Robust forelimb bones protect the animal from violent stresses during grappling. S.Populator : 14% X.Hodsonae : 12% Edge : S.Populator Overall : S.Populator References : pubmed.ncbi.nlm.nih.gov/16235255books.google.co.ma/boo...n%20hemisphere&f=false |

Xenosmilus still quite impressive, didn't think it would be that close.

I don't know why I always dismissed xenosmilus as like a knock off "wish" version of the sabre toothed cats, now I'm wondering if I even have the right cat in mind. Is this the sabre tooth native to south America prior to the land bridge connection to North America? Which preyed on sloths and armadillos?

Well xenosmilus fossils were found in North America and not once in South America so we can never know whether or not it crossed the bridge. |

Well xenosmilus fossils were found in North America and not once in South America so we can never know whether or not it crossed the bridge. I'm an idiot. I just realised I was confusing xenosmilus with thylacosmilus. Yes not even a cat, but somewhere along the way I blended those two. I used to actually be a prehistoric cat nerd but I've become really rusty and need to take a refresher course. |

There is a popular belief that Panthera Atrox could have a maximum weight of 500 kg. However, the study in question was proven to overestimate weights and a more reliable study puts the max weight at 350 kg :  www.jstor.org/stable/20627102American Lions could still potentially have specimens exceeding 350 kg. However, assuming that there is an individual reaching 500 kg is nothing more than a stretch. |

If lions and tigers went extinct and lion and tiger bones were dug up today, do you think they'd estimate them at a higher weight than what they actually weigh?

Although I'm not really sure since we technically rely on modern cats that are closely related to estimate their prehistoric counterparts and even then, certain estimates can be accurate and others can either overestimate or underestimate their real weight. |
