The largest freshwater turtle of all time was the Miocene podocnemid Stupendemys, with an estimated parasagittal carapace length of 2.86 m (9 ft 5 in) and weight of up to 1,145 kg (2,524 lb). [296] Carbonemys cofrinii from the same family had a shell that measured about 1.72 m (5 ft 8 in), [ 297 ] [ 298 ] [ 299 ] complete shell was estimated at ...
