Acanthopholis is a known only from sparse fossil record of the genus bird Beck dinosaur ( Ornithischia ) from the group of Ankylosauria.
The findings of Acanthopholis limited so far to individual teeth, skull fragments, bone plates, vertebrae and parts of the limbs, but it is uncertain whether they all belong to the same genus. While the membership is fixed to the ankylosauruses, would have difficulty with details of the appearance of this dinosaur make. Presumably, he was covered with an armor of bony plates, in addition in the neck and shoulder area spines were present. He moved like all Ankylar quadruped continued and was a herbivore.
The findings of Acanthopholis from England and were first described in 1867 by Thomas Henry Huxley. The name is derived from the Greek words akantha ( = "thorn " or " thorn" ) and pholis ( = " scale "). Type species is A. horridus, more described species are A. macrocercus, A. eucercus (a very dubious discovery of two vertebrae ), A. platypus and A. stereocercus. All of these species are considered nomina dubia, that is, there are too few finds for a detailed species description available.
The finds are dated to the late Lower and early Upper Cretaceous ( Aptian to Cenomanian ) to a retirement 126-94 million years ago.
