Bronze Age solid-disk wheel carts were found in 2018 at Sinauli, which were interpreted by some as horse-pulled "chariots," predating the arrival of the horse-centered Indo-Aryans. They were ascribed by Sanjay Manjul, director of the excavations, to the Ochre Coloured Pottery culture (OCP)/Copper Hoard Culture, which was contemporaneous with the Late Harappan culture, and interpreted by him as horse-pulled chariots. Majul further noted that "the rituals relating to the Sanauli burials showed close affinity with Vedic rituals, and stated that "the dating of the Mahabharata is around 1750 BCE." According to Asko Parpola these finds were ox-pulled carts, indicating that these burials are related to an early early Aryan migration of Proto-Indo-Iranian speaking people into the Indian subcontinent, "forming then the ruling elite of a major Late Harappan settlement."
