Paleoloxodon was genetically related to the African elephant, but morphologically they strongly resembled to the Asian elephant.

I think the femur could be there. I haven't been there in a while & i wasn't specifically looking for it last time either. I intend to go once after June before i leave Kolkata. I'll keep an eye out...
I remember its skull though.

About 6'6" high. Big.. but not 22ton big. I think it had a smallish head compared to its body.
It's about 1.5 times the size of the Stegodon Ganesha skull (±12 tonne)...

...which itself is bit larger than two 6.5tonne Asian elephant skulls (1st one was not wild)

Wasn't Paraceratherium (rhino relative) the largest animal in existance? I remember the paleontologists saying this when they discovered it back then.

Paraceratherium transouralicum (largest specimen could have been upto 20t) lost its crown of "the largest land mammals ever" to Palaeoloxodon namadicus (largest specimen upto 24t) by quite a long shot, if weight is compared, in 2015...i think.

Where is now this partial broken femur, I guess nobody from Western scientists have seen that bone from decades, the conclusion that Paleoloxodon namadicus was the largest land mammal ever in the article is based I guess only on old descriptions and paintings of the femur, I could be wrong.
Its curious why British in 19 century didn't steal that fossils as they usually did in their former colonies?... Probably they didn't realise the colossal size of the specimen to which belonged that femur.
During the British Raj Calcutta as you know was the capital of British India and probably had the second highest density of genius people in the world after London.

Palaeoloxodon namadicus
Several studies have attempted to estimate the size of the Asian straight-tusked elephants, as well as other prehistoric proboscideans, usually using comparisons of thigh bone length and knowledge of relative growth rates to estimate the size of incomplete skeletons.
One partial skeleton found in India in 1905 had thigh bones that likely measured 165 centimetres (5.41 ft) when complete, suggesting a total shoulder height of 4.5 metres (14.8 ft) for this individual elephant.
Two partial thigh bones were found in the 19th century and would have measured 160 cm (5.2 ft) when complete. A fragment from the same locality was said to be almost a quarter larger; volumetric analysis then yields a size estimate of 5.2 metres (17.1 ft) tall at the shoulder and 22 tonnes (24.3 short tons) in weight. This makes P. namadicus the largest land mammal known, surpassing the largest indricotheres.

Here is the subfossilized tusk of Paleoloxodon namadicus from the eastern China, and it appears that they had survived until 6000-5000 BC.

The largest specimen (22 tons) was found in the aria of Narsinghpur. From that animal didn't survive any skull, any skeleton, even the femur is not whole, but only 1/3. Rishi if he visits the museum might look only for SMALL FRACTION OF THE FEMUR. I think nobody has yet published in Internet a image of that partial bone. Rishi could be the first one to make and publish such a photo. It could be that bone is not in open exposition for the public.
On the base of that partial femur scientists calculated the length of whole femur, and than was calculated that animal was 5,2 meters tall and weighted 22 tons.

Steppe Mammoth figure based in scientific evidence. Reconstruction based in several individuals, the complete skull from Novosibirsk and scaled up to the largest individuals from Mosbach.

Clash of the Titans
The find consisted of two massive bull-mammoth skulls with their tusks locked together, each mammoth had one full tusk and one broken tusk. This asymmetry msy explsin how the two came to be locked together. With elephants with two complete tusks fight they are kept at a distance by the curve of theirs tusks and the bulk of their trunk. Adversaries with broken tusks have no such buffer and can get much closer to each other, using the good tusk like a spear for stabbing.
Around 12.000 years ago this is exactly what must have happened when the two mammoths squared off against each other. As they pushed and shoved one mommoth punched a hole through the shoulder blade of his opponent, probably using his broken tusk. As the fight continued, the tusk somehow became irreversibly interlocked. The animals no doubt struggled in this state to the point of exhaustion, when they collapsed, dragging each other down.
Locked in a fatal embrace, they eventually died.
