The image shows a display case with three small rocks on a red velvet surface. The rocks are of different sizes and shapes, with some having a rough texture and others having a smooth surface. They are arranged in a triangular formation, with the largest rock in the center and two smaller rocks on either side. Above the rocks, there is a white sign with Chinese text that reads "Macroolithus yaotunensis, Age: Late Cretaceous, Locality: Nanxiang city, Guangdong Province, Xixia Dinosaur Park, Nanyang, China". The background of the display case is a stone wall.
