This dinosaur is a neoceratopsian, a group of early horned dinosaurs that did not have big horns yet.1
Sasayamagnomus lived alongside other dinosaurs like the long-necked Tambatitanis and the troodontid Hypnovenator.1
The holotype specimen is only about 80 centimetres (2.6 feet) long, but it was not fully grown.1
