Barilium is a genus of iguanodontian dinosaur which was first described as a species of Iguanodon (I. dawsoni) by Richard Lydekker in 1888, the specific epithet honouring the discoverer Charles Dawson, who collected the holotype during the 1880s. ::figure[src="https://upload.wikimedia.org/wikipedia/commons/3/33/Barilium_vertebra.jpg" caption="Middle dorsal vertebra"] ::
In 2010 it was reclassified as a separate genus by David Norman. The generic name Barilium is derived from Greek barys, "heavy", and Latin ilium. Later in 2010, Kenneth Carpenter and Yusuke Ishida independently assigned it to the new genus Torilion, which is thus a junior objective synonym of Barilium. It is known from two partial skeletons found near St Leonards-on-Sea in East Sussex, England, from the middle Valanginian-age Lower Cretaceous Wadhurst Clay. Lydekker based the species on the syntype series BMNH R798, 798a, 803-805, 806, 798b, 802, 802a and 799-801. Norman chose NHMUK R 798 and R802, a dorsal vertebra and a left ilium, as the lectotype.
A contemporary of Hypselospinus (also once thought to be a species of Iguanodon), Barilium was a robust iguanodontian estimated at 8 m long.
Barilium is separated from Hypselospinus on the basis of vertebral and pelvic characters, size, and build.
