Two young girls look up at a taxidermied gorilla in a glass display case. The gorilla’s head is angled such that it appears to be making eye contact with the children. A digital rail, a screen on a stand, is positioned in front of the case. In the background, large-scale photographs of objects are affixed to the wall.

Five images of fossils are combined into a grid. Each fossil has text identifying it. A rounded seashell protruding from rock is labeled as an Orthospirifer brachiopod; a flat, leaf-like seashell is labeled as Strophomenid brachiopod; a circular ring in rock is a crinoid; a lacy fossil on a rock surface is a bryozoan; and a wavy depression in rock is a cephalopod.
