The image is a large poster on a wall in a museum or exhibition space. The poster is titled "Evolution of Dinosaurs" and has a blue background with white text. It is divided into two sections, with the top section showing the different types of dinosaurs and their habitats.

The top section of the poster has a list of dinosaurs in different colors and sizes, with each dinosaur represented by a different color. The dinosaurs are arranged in a grid-like pattern, with some overlapping each other. The colors range from light blue to dark blue, and the sizes range from small to large. The text on the poster is written in both English and Chinese, and it appears to be explaining the evolution of dinosaurs over time.
