Archaeologists in Mexico have uncovered an intricately carved stone they believe was used as a scoreboard for pelota, a ball game played by the Maya hundreds of years ago.
The circular stone was found at the Chichen Itza archaeological site and is thought to be around 1,200 years old.
At its centre are two players in elaborate headgear surrounded by hieroglyphic writing.
Experts are now analysing the writing to decipher its possible meaning.
The 40kg-stone (88lb) was found by archaeologist Lizbeth Beatriz Mendicut Pérez in an architectonic compound known as Casa Colorada (Red House).
