The image shows a fossil of a fish on a rock in the desert, with a scale and text at the bottom. The fossil appears to be a brachiopod, a type of fish native to the desert. It has a long, slender body with a segmented head and two antennae. Its wings are spread out and its legs are tucked in close to its body. The scale is likely used to measure the size and shape of the fossil.
