The Oldeani Monster is a Lost species of chameleon found in Tanzania. On February 25, 1962, Peter Scott and John and Jane Hunter saw a large chameleon in the Ngorongoro Conversation Area near Oldeani Peak, Tazania. They captured it, and Scott took it back to England, where it lived for a full 18 months. Its remains were preserved a short time before they were lost. No one was able to determine the animal's identity.
It was a brown chameleon, with small red spots and a horizontal stripe across each flank. It had a small horn at the tip of its snout and had a long tail.
