Other species may have filled this niche in the Pliocene, [93] [97] such as the fossil killer whale Orcinus citoniensis which may have been a pack predator and targeted prey larger than itself, [30] [98] [99] [100] but this inference is disputed, [23] and it was probably a generalist predator rather than a marine mammal specialist.
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 ...

Besides the most common hypothesis that it was an active predator, a variety of other theories existed in the late 19th to early 20th centuries as to the diet and feeding of Thylacoleo, with hypotheses of it being a scavenger filling the ecological niche of hyenas, [33] being a specialist of crocodile eggs, [29] or even a melon-eater.

Based on the size of the vertebrae, Titanoboa is the largest snake in the paleontological record. In modern constrictors like boids and pythonids , increased body size is achieved through larger vertebrae rather than an increase in the number of bones making up the skeleton, allowing for length estimates based on individual bones.
The largest dinosaurs, and the largest animals to ever live on land, were the plant-eating, long-necked Sauropoda. The tallest and heaviest sauropod known from a complete skeleton is a specimen of an immature Giraffatitan discovered in Tanzania between 1907 and 1912, now mounted in the Museum für Naturkunde of Berlin.
