content: This specimen is a fossilized partial tusk from a member of the Proboscidean order. The only living family of this order today is Elephantidae, better known as the elephant family. The tusk's cross section of Schreger lines exhibits an "engine turning" design because the fine intersecting lines are in a rounded diamond shape like a turning engine. Ivory dentine displays unique Schreger lines and is used to differentiate between the mammals. This partial tusk has a 3.8cm diameter and measures 5cm in length.
