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.
These were truly giant cheetahs. Look at the specimens estimated at over 100 kg. I see van Valkenberg formulas were used, but as these are small cats on a relative scale, they would be more prone to underestimation than overestimation due to allometry.
How much is the difference between the in-flesh and bone skull length? Looking at 154 mm Italian mandible, I estimate a GSL of 231 mm. If I add 30 mm to convert to an in-flesh measurements and isometrically compare to modern wild cheetahs, we get (261 mm/227 mm)^3 * 62.4 = 95 kg.
For the 24.4 mm lower M1 specimen, I translate a bone skull length of 24.4/21.3*231 = 264.6 mm, so an in-flesh length of 300 mm, and thus a mass of 144 kg!
I'm not certain if added too much/too little to adjust for the in-flesh length, but regardless, truly "freak" cheetahs. As always, paper attached.
