Sellacoxa is a genus of iguanodont dinosaur which existed in what is now England during the Early Cretaceous period (lower Valanginian stage, around 140 mya).[1]

Identified from a nearly complete right ilium, pubis, ischium, and thirteen articulated posterior dorsals and sacrals (holotype NHMUK R.3788) found in May 1873 by John Hopkinson in the Old Roar Quarry, at Silverhill, near Hastings, from the lower Wadhurst Clay of East Sussex, England,[2] that David Norman (2010) regarded as an individual of Barilium.[3] It was named by Kenneth Carpenter and Yusuke Ishida in 2010 and the type species is Sellacoxa pauli.[1] The generic name means “saddle” (sella in Latin) + “hips” (coxa) in reference to the saddle-shaped ilium, and the specific name honors Gregory S. Paul for recognising that European iguanodont diversity is higher than previously assumed.[1]

In a 2013 publication, David Norman did not consider Sellacoxa distinct from Barilium and noted that Carpenter and Ishida overlooked a left ilium, dismissing diagnostic characters of the ilium as a result of distortion.[4]
