This view is looking straight down at a bedding plane. A large horizontal ophiomorpha trace is pictured. This is a great view of the individual pellets that line and support the burrow walls.

A vertical ophiomorpha trace. Notice how the resistant burrow walls appear to be smooth but when you look at the imprint where the burrow has been weathered away you observe the indentations where the pellets used to be!
