Xp. Suberbiola et Pm. Barrett, A systematic review of ankylosaurian dinosaur remains from the Albian-Cenomanian of England, SP PALAEONT, (60), 1999, pp. 177-208
Ankylosaur material from the upper Lower Cretaceous to lower Upper Cretaceo
us (Albian-Cenomanian) of south-eastern England is reviewed systematically.
'Acanthopholis horridus' from the Lower Chalk of Folkestone (Kent) is rega
rded as a nomen dubium. A re-evaluation of the ankylosaur specimens from th
e Cambridge Greensand (mostly probably reworked from the underlying Gault C
lay) suggests that all of the species of 'Acanthopholis' erected by Seeley,
on the basis of fragmentary, and often composite, non-diagnostic material,
are invalid. Anoplosaurus curtonotus Seeley is removed from the Ornithopod
a, and provisionally regarded as a valid taxon of nodosaurid ankylosaur. A
lectotype, a partial scapula, is designated for this species. Anoplosaurus
appears to be a relatively primitive nodosaurid which retains several plesi
omorphic features in the lower jaw, sacrum and appendicular skeleton.
