Field notes
About Dubreuillosaurus
What it was like
Dubreuillosaurus was a megalosaur, a two-legged meat eater related to Megalosaurus. Its skull was long and very low, and it may have fed on fish and other animals along the coast.
Its world
It lived in the Middle Jurassic, in what is now France. At the time the area was a coastline with mangrove-like swamps.
How it was found
Allain named Dubreuillosaurus in 2005, from a skeleton first described as a species of another megalosaur. The fossil had been found in a quarry, broken into many pieces.

The science behind Dubreuillosaurus
Which parts of the picture come from its own bones, and which come from its relatives.
From its own fossils
- A nearly complete skull has a long, low profile without bony crests.
- The same skeleton preserves parts of the backbone, ribs and limbs.
Borrowed from relatives
- Missing parts of the skeleton are restored from megalosaurs such as Eustreptospondylus and Afrovenator.
Still unknown
- Its adult size.
- Its skin covering and color.
- Whether it belongs in a separate genus.
