The image shows a display case with two large fish skeletons hanging on the wall. The skeletons are of different sizes and shapes, with the largest one on the left and the smallest one in the center. The largest skeleton is a long, slender fish with a pointed snout and a long tail. The smaller one is a smaller, elongated fish with sharp teeth and a pointed head. Both skeletons are displayed on a blue background with a white border.

On the right side of the display case, there is a sign that reads "Take an underwater journey through the Mesozoic era." Below the skeleton, there are several small rocks and fossils scattered on the floor. The display case appears to be in a museum or exhibition space, as there are other exhibits visible in the background.
