Megalodon teeth can measure over 180 millimeters (7.1 in) in slant height (diagonal length) and are the largest of any known shark species, [29]: 33 implying it was the largest of all macropredatory sharks. [35] In 1989, a nearly complete set of megalodon teeth was discovered in Saitama, Japan.

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) [151] and having a total body length of more than 4 m (13 ft). [152] [153] Only the modern male elephant seals reach similar sizes. [152]
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 elephant ever recorded was shot in Angola in 1974. It was a male measuring 10.67 metres (35.0 ft) from trunk to tail and 4.17 metres (13.7 ft) lying on its side in a projected line from the highest point of the shoulder, to the base of the forefoot, indicating a standing shoulder height of 3.96 metres (13.0 ft).
The largest true crocodile ever existed is Euthecodon which estimated to have reached 6.4–8.6 m (21–28 ft) or even 10 m (33 ft) long. [122] [123] Gharials are long, narrow-snouted crocodilians, and are among the largest species. A 6.55 m (21.5 ft) long gharial was killed in the Ghaghara River in Faizabad in August 1920. [124]
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.
Jaekelopterus is the largest known eurypterid and the largest known arthropod to have ever existed. This was determined based on a chelicera (claw) from the Emsian Klerf Formation of Willwerath, Germany , that measures 36.4 centimetres (14.3 in) long, but is missing a quarter of its length, suggesting that the full chelicera would have been 45. ...
