Thanks alot for the info and data.
Thanks again for clearing out my doubts.
But I still have some doubts and I hope you can help me here 

Asper your data posted by Pckts

Ngandong tiger

Body size:
* Head-body length: 210 – 230 cm.
* Total length: 316 – 345 cm.
* Shoulder height: 115 cm.
* Weight: "By the way, the body mass of the Ngandong tiger (P. t. soloensis) must be updated. The new investigations made by Tigerluver and me put the body mass of this great cat between 370 kg (using the Christiansen & Harris (2005) equations) and 415 kg (Tigerluver new equations). This surpasses the weight of the largest Panthera atrox and Panthera (leo) fossilis and match with the largest Smilodon populator."


Panthera leo fossilis
About the size of Panthera atrox, probably up to 320 kg and estimated at 240 cm in head-body length.


Panthera leo spelaea
Large animal, 8-10% larger than modern lions. Largest skull of 420 cm. WaveRiders mentioned one of c.440 cm, but no evidence was presented. It probably weighed up to 300 kg, although this is debatable. Body length estimated at 220 cm.


Panthera Atrox
* Head and Body Length: 1.6 - 2.5 m (5.3 - 8.2 ft) (Shaw 2005)
* Tail Length: .5 - .8 m (1.7 - 2.7 ft) (Shaw 2005)

The maximum shoulder height estimated by Turner & Anton (1996) was of 125 cm.
Average weight : 250Kg (upto 320Kg)


My doubt is eventhough these cats are similar in dimensions, the Ngandong tiger seems to outweigh all of them by a big margin.
Panthera leo fossilis and Panthera atrox seems to get higher headbody length of 240cm and shoulder height 125cm when compared to Ngandong tiger (Head body length 230cm and Shoulder height 115cm) but still they weigh less than the Ngandong tiger. What is the reason ? Is there is any difference in the body construction ?


 

The largest Ngandong tiger is like Baikal, standing about 4 feet tall at shoulder and being 8 feet in the head+body length.

When the body dimension is similar, the tiger-like cat often weighs more than the lion-like cat.

 

Yeah a tiger like cat will often weigh more than a lion like cat at similar body dimensions.
But here the weight difference is much higher (P.atrox avg 250Kg (upto320Kg) and Ngandong tiger (370-415 Kg)).
The weight difference seems to be much higher even for tiger like cat when compared to a lion like cat at similar dimensions.
Provided that the P.atrox is capable of reaching bigger body dimensions than Ngandong tiger.
 

Actually the largest specimen for P. atrox is 351 kg based on a skull. P. atrox may have had proportionately larger skulls as well. No fossil specimens from this species on record has the dimensions that a tiger with a femur of 480 mm would have. A couple of P. s. fossilis specimens on record (a 465 mm ulna and 484.7 mm skull) probably had similar dimensions to the largest Ngandong tiger. I think my equations estimated it around 386 kg.  Reply
