    Deep in the forest of southeastern Mexico, scientists found a surprise. They found an ancient pyramid (金字塔). There were colorful murals in it. A mural is a painting on a wall. Those murals are helping scientists unlock a mystery (奥秘) about people who lived in ancient times.

The murals are about 1,350 years old. That's more than five times older than the United States. Scientists say the paintings belonged to the Mayas. That was a group of Native American people.

Scientists are excited about the discover because they don't know much about the Mayas daily life, explains Michael Coe, an expert on the Mayas. The paintings show how the Mayas worked, shopped and had meals.

"Mostly we get the murals that show gods and kings, never anything about the daily life, " Coe said. So far, scientists have found more than 30 murals in the pyramid. They are not sure why the Mayas created them. The experts hope to learn more as they continue their search. "We never had anything like this before," said Coe. "These are really special murals."

Scientists learned a lot about the Mayas from the murals. The Mayas were known for more than paintings. Now the murals tell us some fun facts about the Mayan way of life.
