Megalosaurus bucklandii
Megalosaurus (meaning "Great Lizard", from Greek, μεγαλο-/megalo- meaning 'big', 'tall' or 'great' and σαυρος/sauros meaning 'lizard') is a genus of large meat-eating theropod dinosaurs of the Middle Jurassic period (Bathonian stage, 166 million years ago) of Europe (Southern England, France, Portugal). It is significant as the first genus of dinosaur (outside of birds) to be described and named. n many ways, Megalosaurus was your garden-variety theropod dinosaur, indistinguishable from a host of other big-headed, large-toothed carnivores of the late Jurassic period. What really sets this predator apart is the fact that it was the first dinosaur ever to be discovered and named: a fossilized femur of Megalosaurus was dug up in England in 1676, but it wasn't until 150 years later--after further discoveries--that it was given its name, Greek for "great lizard," by the early paleontologist William Buckland. Size about 30 feet long with weight estimates varying from 700 kg (1,500 lbs) to 1,100 kg (2,400 lbs).
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.
