The fossil appears to be a photo of an invertebrate, with its wings spread out and its head facing forward. Its body is segmented and its legs are long and thin. Its eyes are large and round, and its mouth is slightly open. The text on the rock is written in a variety of colors, including blues, greens, and yellows.
