The type species, A. kozmai,[1] was originally described as a ceratopsian most closely related to forms in east Asia, from where its ancestors may have migrated by island-hopping.

The generic name, Ajkaceratops, honors Ajka, a town in Hungary where the fossils were first discovered, combined with the given greek nomination ceratops, meaning "horned face".

This has cast doubt as to whether Ajkaceratops possesses a rostral bone in the first place, a defining feature of the ceratopsian group, and instead the hooked beak represents a highly derived, hypertrophied premaxilla.

[3] The fossils of Ajkaceratops were discovered in the Csehbánya Formation, which is interpreted as a floodplain and channel deposit formed by variegated clay, silt with interbedded grey and brown sand, and sandstone beds.

Ajkaceratops shared its environment with other dinosaurs such as Mochlodon, the nodosaurid ankylosaurs, other non-avian theropods and enantiornithine birds, as well as eusuchian crocodiles, azhdarchid pterosaurs, bothremydid turtles and teiid lizards.
