Drawing of a Proconsul skull, done in pencil, 2015. Proconsul is thought to be an ancestor of monkeys and apes. The skull shown here is the most complete fossil skull known of this animal, and unfortunately it is deformed due to mineral leaching from the bone. This caused the bone to become flexible and pliable, and sediment that covered the skull caused it to become compressed. The result is an oddly warped skull. As a future scientific illustrator I have to draw a specimen as it appears, but later on I can work on reconstructing it to see how the skull would have really looked before it fossilized.
