Megalosaurus was the first dinosaur to be named. Despite this, not much is known about it, and no full specimens have been discovered.
Megalosaurus was typical theropod dinosaur, standing on two legs, and having short arms and a long tail.
It was between 7 and 9 m (23 and 30 ft.) in length and weighed around 1 tonne (1.1 short tons).
Megalosaurus had a large head. Its powerfuljaws were filled with long teeth ideal for cutting through meat!
Megalosaurus lived around 166 million years ago, during the mid-Jurassic period
The first Megalosaurus fossil was discovered in 1676 in the Taynton Limestone Formation, in Oxfordshire, England.
Consisting of just part of a bone, it caused confusion among the biologists of the time.
Although they saw that it could not belong to any British animal, they didn’t realize that it came from a completely ‘new’ type of animal dinosaurs had yet to be discovered.
One scientist of the day thought that the bone came from an elephant brought to England by the Romans. Another thought that it came from a giant human!
Over the years more Megalosaurus bones were found in England.
These included part of a jawbone, part of a spine, and part of a pelvis. In the early 1820’s paleontologist William Buckland realized that the bones belonged to giant reptiles.
In 1822 James Parkinson announced the name ‘Megalosaurus’, which means ‘giant’, or ‘great’ ‘lizard’.
It was the first dinosaur to be given an official name.
In 1827, Gideon Mantell wrote about Megalosaurus in a geologicalsurvey of south east England, naming the species Megalosaurus bucklandii, after William Buckland.
Together with Iguanodon and Hylaeosaurus, Megalosaurus was one of the three examples Richard Owen gave in 1842 when he announced the discovery of a new type of animal the dinosaur.
It’s not just fossilized bones that are used by scientists to piece together what happened in the Mesozoic Era; fossilized Megalosaurus footprints have also been found!
