The story in short
In 1883, H. G. Seeley published the name Sphenospondylus.
Fossils referred to Sphenospondylus date to the Early Cretaceous, within an age that is only broadly constrained. Finds come from the United Kingdom. It was a herbivore. A habitual gait is not settled.
The fossils of Sphenospondylus are too incomplete for a responsible length, hip height, or weight, so those fields are left blank on purpose.
On the family tree it sits in Iguanodontia, among the ornithopod dinosaurs.
