Proceratosaurus, a genus consisting of small-sized (3m (9.8ft)) carnivorous dinosaurs from the Middle Jurassic of England (Bathonian), is known as. The name Proceratosaurus refers to the fact that it was initially thought to be Ceratosaurus’ ancestor. This is because the partially preserved portion from the crest Proceratosaurus resembles Ceratosaurus’ small crest. It is now considered a coelurosaur and a member the Proceratosauridae family.

The specimen is kept in the Natural History Museum, London. It was discovered in 1910 while excavating for a reservoir.

Arthur Smith Woodward, a British palaeotnologist, reported in 1910 that a partial theropod skull had been discovered by F. Lewis Bradley while digging for a reservoir at Minchinhampton. Minchinhampton is a town in the Cotswolds, Gloucestershire, England. Bradley had made the skull visible on the left and submitted it to F. Lewis Bradley, the Geological Society of London. It is now housed at The Natural History Museum as specimen NHMR 4860. Due to the fissure in the rock that had eroded it, the skull’s upper portion was missing. It was then partially filled with Calcite. Woodward named the skull M. bradleyi in his honour as the holotype of a new Megalosaurus species. It was the largest known European theropod skull, perhaps except for the hard-to-understand skulls of Compsognathus or Archaeopteryx, at the time it was found.

Friedrich von Huene, a German Palaeontologist, moved the species to the new Genus Proceratosaurus in 1923. He assumed it was the Jurassic ancestor of Ceratosaurus. However, since the name was not used in a schematic, it has been considered a nomen Nudum, an invalidly published title. Three years later, he validated the name in two 1926 articles with a diagnosis of genus. It is one of Europe’s best-preserved theropod skulls and the world’s best preserved Middle Jurassic skulls. However, the skull has received very little scientific attention. Since CT scanning at the University of Texas revealed the holotype skull, it was further mechanically prepared to reveal more details of the skull and jaw. In 2010, Oliver W. M. Rauhut, a German Palaeontologist, re-described the skull.
