Rizal

Rizal (formerly known as Liwan), officially the Municipality of Rizal is a 4th class municipality in the province of Kalinga, Philippines. According to the 2015 census, it has a population of 17,038 people.^[3]

The town is famous for its Pleistocene sites which possesses rhino bones, tools, deer bones, turtle remains, and stegodon bones. The butchered rhino bones were confirmed by international scientific journals as proof of ancient hominids in the Philippines dating back to 709,000 years ago, the oldest hominid evidence in the entire Philippine archipelago. The discovery was confirmed in 2018, and has been a game-changer in Philippine prehistory.
