Fun facts
Juratyrant is known from just one partial skeleton, including a complete pelvis, leg bones, and vertebrae.1
It was first thought to be a species of Stokesosaurus, but scientists later gave it its own genus in 2013.12
The fossil was discovered in 1984 by a commercial fossil collector named Peter Langham, and the species was named after him.1
Juratyrant lived during the Tithonian age of the Late Jurassic, about 149.3 to 149 million years ago.15
Scientists estimate Juratyrant weighed between 300 and 648 kilograms, about as much as a large cow.1
It had a 'folded' appearance on part of its hip bone, which is one of the unique features that sets it apart from other tyrannosaurs.2
