Final answer:
The Ambum Stone is a Neolithic greywacke sculpture from the Ambum Valley of Papua New Guinea, dating to around 1500 BCE, not a ceramic nor from the Iron Age or Central Mexico.
Step-by-step explanation:
The Ambum Stone is an ancient sculpture discovered in the Ambum Valley of Enga Province, Papua New Guinea and is thought to have been created around 1500 BCE. The medium used to create this piece is indeed greywacke, also known as sandstone. Despite the mention of Central Mexico, the Ambum Stone is not from that region; rather, it is from Papua New Guinea. The statement describing it as a ceramic figurine is incorrect as it is a stone carving. Additionally, the time period mentioned, the Iron Age, is not accurate for this artifact's creation. The Ambum Stone predates the Iron Age, as it was made during the Neolithic, which is also known as the New Stone Age.
