== Description == left|thumb|Size comparison one of the largest known Paraceratherium individuals compared to a giraffe and a humanThe necks and limbs of paraceratheriids are elongate relative to those of living rhinoceroses. The earliest paraceratheres like Juxia were comparable in size with living rhinoceroses with a body mass of three quarters to one and a half tons, while later members grew substantially larger, with the largest representatives (Paraceratherium, Dzungariotherium) estimated to have a body mass of 17 to possibly over 20 tonnes, making them the largest land mammals to have ever lived (though possibly equalled or exceeded by some proboscideans in body mass). Non-fostercoopine paraceratheriids are united by the possession of a retracted nasal notch, a lack of contact between the premaxilla and nasal bones of the skull, enlarged upper and lower first incisors and small lower canine teeth, along with characters relating to the size and shape of the molars and premolars.left|thumb|Artist's reconstruction of Paraceratherium.
