化石 (huà shí): fossil

When the children saw the dinosaur fossils in the museum, they were all so amazed that their mouths fell open.

Scientists discovered fossils of ancient humans in the desert, which provided important clues for studying human origins.

This fossil is remarkably well-preserved; even the fine veins on the leaf are clearly visible.

By analyzing the carbon in the fossils, archaeologists deduced that these organisms lived millions of years ago.

Due to geological movements, fossils from the seabed were pushed to the mountain top, and now they have become a wonder in the eyes of climbers.
