Aesculus hickeyi was common in the Paleocene of Wyoming, Montana, North Dakota, and Alberta. It is known from completely preserved palmately compound leaves as well as abundant shed leaflets, occasional spiny fruit capsule remains, and associated dispersed pollen ( Manchester 2001). The leaflets are recognizable by acute bases, short or absent petiolule, and, in this species, a marginal serration consisting of very fine, closely spaced teeth. Tertiary venation is percurrent and weakly impressed.
