Barilium
''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. 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'',〔Carpenter, K. and Ishida, Y. (2010). "(Early and “Middle” Cretaceous Iguanodonts in Time and Space. )" ''Journal of Iberian Geology'', 36 (2): 145-164.〕 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 metres long (26.2 ft). ''Barilium'' is separated from ''Hypselospinus'' on the basis of vertebral and pelvic characters, size, and build.〔 For example, ''Barilium'' was more robust than ''Hypselospinus'', with large ''Camptosaurus''-like vertebrae featuring short neural spines, whereas ''Hypselospinus'' is known for its "long, narrow, and steeply inclined neural spines". ==References==
