The story in short
In 1928, B. F. Nopcsa published the name Polacanthoides. The name means “resembling Polacanthus.”
Fossils referred to Polacanthoides date to the Early Cretaceous (Barremian), roughly 125.8 to 121.4 million years ago. Finds come from the United Kingdom. It was a herbivore and walked on four legs.
The fossils of Polacanthoides 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 Ankylosauria, among the armored dinosaurs.
