There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Freak Felids - A Discussion of History's Largest Felines

Agreed @GuateGojira.

The number 1 issue is that these formulas are made with a bit of a fallacy. They use published means of weights but then use the mean of the 10 or so specimens the authors measure themselves. Most authors still use this method, except for Christiansen. When you use y-values that didn't belong to the x-values, overestimation and underestimation is going to happen. 

Another issue is that random chance within the small sample size can give a scale factor which underestimates or overestimates the specimen inaccurately. Isometry may be the safe bet in my head sometimes, as we're using a law to predict mass rather than scale factors that could have been skewed by random chance of the sample. 

I think I'll take a look at old jaguars to see if they were supersized as well, will post back soon. Dr. Marciszak has the crania of those specimens covered very well too. From here, I'll just use isometry to give mass values.
