Fossil insect trackway

A small fossil insect trackway from the Minkin site in central Alabama. This is the ventral side of the slab, so footprints have positive relief. On the left, you see a shallow undertrack on a layer close to the original sediment surface. On the right, you see a deeper layer, on which the trackway was more shallowly impressed. Same trackway, same insect, but preserved slightly differently on different layers.
