This species belongs to the genus Palaeolagus, which is considered one of the earliest and most primitive lagomorph groups, showing traits that connect ancestral mammals to modern rabbits and hares. Fossil evidence of Palaeolagus hayeni primarily consists of cranial and dental remains, which are crucial for its identification and classification.
