Titanoboa cerrejonensis
Titanoboa (/tiˌtɑːnoʊˈboʊə/) is an extinct genus of very large snakes that lived in what is now La Guajira in northeastern Colombia. They could grow up to 14.6 m (48 ft) long and reach a weight of 2 tons (4,400 lb).[1] Fossils of Titanoboa have been found in the Cerrejón Formation,[2] and date to around 58 to 60 million years ago. The giant snake lived during the Middle to Late Paleocene epoch,[3] a 10-million-year period immediately following the Cretaceous-Paleogene extinction event.[4] The only known species is Titanoboa cerrejonensis, the largest snake ever discovered,[3] which supplanted the previous record holder, Gigantophis.
Megaraptor namunhuaiquii
Megaraptor was initially described as a giant dromaeosaur, known primarily from a single claw (about 1 ft/0.30 m long) that resembled the sickle-shaped foot claw of dromaeosaurids. The discovery of a complete front limb, however, showed that this giant claw actually came from the first finger of the hand. The hands were unusually elongated, bearing sickle-shaped claws even more recurved than those of spinosaurids. The hand is quite distinct from other basal tetanurans, so it was not initially clear whether Megaraptor was an allosaurid, a carcharodontosaurid, a spinosauroid, or something else entirely. Subsequent studies, as well as the identification of close relatives with similar large claws on the forelimbs (see below), have helped identify Megaraptor as a highly advanced and lightly-built allosauroid, and a member of the family Neovenatoridae. In 2010, Gregory S. Paul estimated its length at 8 metres (26 ft), its weight at 1 tonne (2,200 lb).
NOTE: Megaraptor was actually a tyrannosauroid and ranged from 1-2 tons, 1.5 tons average.
