Abstract

Ginkgoalean leaves attributed to Ginkgoites myrioneurus sp. nov. and associated long and dwarf shoots were collected from the Lower Cretaceous coal-bearing Muling Formation of the Jixi Basin, eastern Heilongjiang, China. The common characteristic feature of the various leaves is the dense venation. The species may be distinguished from other known species of Ginkgoites from the Jurassic and Lower Cretaceous of eastern Asia in having 8–18 closely arranged oblanceolate segments each with 6–16 veins. The fragmentary long and dwarf shoots are similar to those of extant Ginkgo biloba in gross morphology. They are considered to belong to the same tree as that which produced Ginkgoites myrioneurus.
