Liriodendrites is an extinct genus of plants, known from fossil leaves. These have a forked apex (bifurcate), like those of extant species of Liriodendron.[1] They have been interpreted as transitional between the leaves of the extinct genus Liriophyllum and Liriodendron.[2] The genus has been placed in the family Magnoliaceae.[3] Five species are known: L. aeternus,[1] L. bradacii,[4] L. laramiense,[5] L. occidentalis[1] and L. sachalinensis.[1] It has been discovered in the United States (Hell Creek Formation), Egypt (Bahariya Formation) and Russia (Sakhalin and Siberia).
