Fasolasuchus is likely the largest known "rauisuchian", with an estimated length of 8 m (26 ft) [3] to 10 m (33 ft). [ 4 ] [ 5 ] This would make Fasolasuchus the largest terrestrial predator to have ever existed save for large theropods , surpassing the Cenozoic Barinasuchus , the "rauisuchian" counterpart Saurosuchus at 7 metres (23 ft), and ...

The largest dinosaurs, and the largest animals to ever live on land, were the plant-eating, long-necked Sauropoda.

The biggest odobenid and one of the biggest pinnipeds to have ever existed is Pontolis magnus, with a skull length of 60 cm (24 in) (twice as large as the skulls of modern male walruses) [153] and having a total body length of more than 4 m (13 ft). [154] [155] Only the modern male elephant seals reach similar sizes. [154]
