A Mesozoic reptile is believed to have been the largest flying animal that ever existed: the pterosaur Quetzalcoatlus northropi, from North America during the late Cretaceous. This species is believed to have weighed up to 126 kg (278 lb), measured 7.9 m (26 ft) in total length (including a neck length of over 3 m (9.8 ft)) and measured up to ...
The snake elements were described as those of a novel, giant boid snake that they named Titanoboa cerrejonensis. The genus name derives from the Greek word "Titan" in addition to Boa, the type genus of the family Boidae. The species name is a reference to the Cerrejón region it is known from.

The first specimen, recovered in 1971 from the Javelina Formation of Texas, United States, consists of several wing fragments.
Archelon is an extinct marine turtle from the Late Cretaceous, and is the largest turtle ever to have been documented, with the biggest specimen measuring 4.6 m (15 ft) from head to tail and 2.2–3.2 t (2.4–3.5 short tons) in body mass.
The largest non-dinosaurian terrestrial reptile to have ever lived were crocodilomorphs such as Deinosuchus, Sarcosuchus and Purussaurus, each have weight varying between 5-10 metric tons. [ 84 ] [ 85 ] [ 86 ] The largest snake to have ever lived was Titanoboa which could grow up to 12.8–14.3 m (42–47 ft) and weigh up to 730–1,135 kg ...
That would make it perhaps the largest-known marine reptile and would rival some of the largest baleen whales alive today. The blue whale, considered the largest animal ever on the planet, can ...
Scientists consider the blue whale, which grows up to 110 feet (33.5 meters) long, to be the largest known animal ever to exist on the planet. But it’s possible that the 202 million-year-old ...
It is the largest terrestrial lizard known to have existed, but the fragmentary nature of known remains make estimates highly uncertain. Recent studies suggest that most known specimens would have reached around 2–3 m (6.6–9.8 ft) in body length excluding the tail, while some individuals would have been significantly larger, reaching sizes ...
