  Megalosaurus - Wikipedia, the free encyclopedia
Megalosaurus ('Great Lizard', from Greek, μεγαλο-/megalo- meaning 'big', 'tall' or 'great' and σαυρος/sauros meaning 'lizard') was a genus of large meat-eating therapod dinosaurs of the Jurassic Period of what is now southern England.
He correctly identifed the bone as the lower extremity of the femur of a large animal and he recognized that it was too large to belong to any known species; he considered it to be the thigh bone of a giant.
In fact, Megalosaurus did have a relatively large head and the teeth were clearly that of a carnivore.

 Megalosaurus- Enchanted Learning Software
Megalosaurus walked on two powerful legs, had a strong, short neck, and a large head with sharp, serrated teeth.
Megalosaurus was up to 30 feet long (9 m), 10 feet tall (3 m), and weighed about 1 ton.
Megalosaurus was a theropod dinosaur, whose intelligence (as measured by its relative brain to body weight, or EQ) was high among the dinosaurs.

When Megalosaurus, Iguanodon and Hylaeosaurus were first discovered and described, most prehistoric scenes, found as the frontspieces in books, primarily focused on marine reptiles and pterosaurs because their skeletons were more well known.
Megalosaurus was also shown walking upon long straight legs, but its skull had a distinctly crocodilian look to it, with a long, narrow snout flattened in the horizontal direction.
Current depictions of Megalosaurus, Iguanodon and Hylaeosaurus are radically different from Owen's restorations (Plates 18, 19, and 20, respectively), which are now looked at as almost laughable in their inaccuracy.

 Megalosaurus: Facts
Although there have probably been dinosaur discoveries dating back thousands of years -- there are, for instance, references to "dragon bones" found in ancient China -- the first documented dinosaur discovery took place in 1676 when a jawbone and teeth were unearthed in Oxford, England.
In 1824, famed paleontologist William Buckland (1784-1856) finally named this first dinosaur Megalosaurus.
Megalosaurus was a large meat-eater that stood up to 9 meters (30 feet) tall and weighed about 1 ton.

 Palaeos Vertebrates 340.100 Theropoda: Basal Theropods
The terms Megalosaur, Megalosauridae, etc are rarely used nowdays, as firstly the original or type species of Megalosaurus is known from only very fragmentary material, and secondly Megalosaurs are a paraphyletic group, defined mostly by shared primitive features, and hence not considered valid in the current, cladistic, paradigm.
The English species Megalosaurus bucklandii was the very first dinosaur to be described, some years before Richard Owen coined the term Dinosauria in 1842.
That is, although the remains are of a large primitive theropod dinosaur of "megalosaur" (or torvosaur) relationships, it is not possible to identify them more closely.

The maxillary and mandibular teeth have sharp-edged triangular crowns, with serrated margins, the serrations being oblique to, or parallel with, the long axis of the tooth.
The sharp posterior median ridge of the tooth extends for the whole length of the crown, and is strongly serrated throughout.
In Megalosaurus the posterior iliac process is a little longer than the postacetabular, and possesses a considerable height.

 The Megalosauria
Megalosaurs were previously included with the Allosaurs and Tyrannosaurs in the polyphyletic (artificial) taxon "Carnosauria." The old-style definition of Carnosaurs is actually an ecotype rather than a true evolutionary group, designating any large (around 200 kg or more in weight) carnivorous theropods, posessing large skulls, short necks, and small forearms.
Unfortunately, the name Megalosaurus, like Plesiosaurus, became something of a taxonomic waste basket, and there is some doubt now among paleontologists whether it even is a valid genus.
Comments: This theropod is based on parts of the upper and lower jaws, both of which have resemblances to both Ceratosaurus and Megalosaurus bucklandii.

Although some Iguanondon teeth and bones had been found earlier, this 2 ton meat eater was the first dinosaur ever to ger a name.
Megalosaurus had teeth were curved on one side, flat on the other and with jagged edges, much like a steak knife.
This dinosaur walked on two legs, but in an 1851 statue in London (which still exsists), it was mistakenly shown on all fours.

Part of this stemmed from historical precedent (Megalosaurus was the first named classic theropod), part of this stemmed from the fact Megalosaurus is not based on the clearest of remains, and part of this stemmed from the fact that what is known of Megalosaurus suggests it was a fairly average big theropod.
Megalosaurus is currently in the midst of a massive taxonomic overhaul, and it is very likely that once this is published we will see the introduction of many new taxa.
Also originally under the Megalosaurus umbrella, the partial skull and skeleton that make up the type of this species were later shown to be distinct from Megalosaurus.

It was among the first dinosaurs to be named, but from very fragmentary remains (and it still is poorly known).
Since its naming in 1824, much material --- most of it unfounded, has been referred to as Megalosaurus, so that this genus has become over the years, a "junk basket" category for remains of any large, little known carnivorous dinosaur.

They base this this conclusion on fossil evidence that the Megalosaurus spent a lot of time hammering Brads and nailing quite a variety of other things as well.
Unfortunately, recent evidence proves that the Megalosaurus hammered only one Brad, albeit again and again and again.
This unfortunate creature (Illustrated in a characteristic position: On all fours with its butt in the air) died a hideous, snuffling, and dusty death when the enormous weight of its overdeveloped head caused it to tip forward and suffocate on one of the enormous dust-bunnies which characterized the period.

 Megalosauroidea   (Site not responding. Last check: 2007-10-29)
Despite worries about the validity of Megalosaurus, it has been universally placed with 'torvosaurids' and 'eustreptospondylids' when the two groups are viewed as part of a larger clade exclusive of birds (Allain, 2002; Holtz et al., 2004).
Megalosaurus has been considered to fall within the definition of Sereno's (2005) Torvosauridae by almost all workers with the exception of Holtz (who placed Megalosaurus and Torvosaurus as successively further from birds in 1994, and successively closer to birds in 2000) and Kurzanov (who placed Torvosaurus further from spinosaurids and allosaurids than Megalosaurus).
Sereno's may have an advantage that Torvosaurus is more often included in analyses than Megalosaurus (Sereno, 1999; Rauhut, 2000; Allain, 2002), but if Megalosaurus is used as the internal specifier for megalosaurids (as it must be) there is an unevenness involved with using Torvosaurus as the external specifier for their sister clade.

Since I had the opportunity of speaking to you on this matter, with the specimens before us, you have made so much progress toward replacing doubts by decisions, that, in truth, there is little now to be said which can appear to you either new or important.
The remains of this animal indicate that it had a length of from 25 to 30 feet; and as teeth of Megalosaurus Bucklandii occur in the Caen stone, Deslongchamps is inclined to suspect that Poikilopeuron may be identical with Megalosaurus.
He however regarded the face of the tibia receiving the condyle-bearing bone as the inner instead of the anterior, stating that the tibia is laterally instead of antero-posteriorly compressed; so anomalous is this structure among Vertebrates.

The first dinosaur to be described scientifically was Megalosaurus.
This genus was named in 1824, by William Buckland; Gideon Mantell (not Ferdinand August von Ritgen) assigned the scientific type species name, Megalosaurus bucklandii.
He had noticed that a group of fossils (which included remains of Megalosaurus, Iguanodon, and Hylaeosaurus) had certain characteristics in common, including:

Both illustrations were direct copies of the life-size sculptures designed by Benjamin Waterhouse Hawkins and erected in Sydenham Park in 1854 (see item 5).
There is also a considerable resemblance between Goodrich's Megalosaurus and the reconstructed drawing by Richard Owen, also made in 1854.

Buckland recognized these bones as belonging to what appeared to be a lizard of enormous size.
He named his find Megalosaurus which means "Great Lizard." According to his calculations, the animal must have exceeded forty feet in length and weighed as much as a large elephant.
Though Buckland was not the first person to find a Megalosaurus bone (Robert Plot described one as far back as 1676) he was the first to realize that these fossils belonged to an unknown class of huge reptiles.
