       Jeholodens was a small triconodont mammal that lived in China during the early Cretaceous.‭ ‬Triconodont mammals like Jeholodens are so named because they have three cusps on the crowns of their teeth.‭ ‬Jeholodens is noted for having bone developments that were fairly advance for mammals during its time of the early Cretaceous.‭ ‬Some of these features include hands capable of grasping and a prehensile tail,‭ ‬all features that would be of a great help when climbing and moving through trees and shrubs,‭ ‬which may also indicate at least a partially arboreal lifestyle for Jeholodens.‭ ‬Jeholodens is also noted for having eyes that were proportionately large for the skull size,‭ ‬which may be a sign that Jeholodens was a nocturnal creature with the larger eyes capable of capturing greater amounts of light.
