Litocarpon beardii is a multifolliculate fruit from the Upper Cretaceous Haslam Formation (late Santonian‐early Campanian) of British Columbia. About 19 follicles are helically arranged on an elongate, slender receptacle. Follicles are winged with the wing extending beyond the locule. Placentation is parietal along the ventral suture, and dehiscence was along the dorsal suture. Seeds are also winged and were derived from anatropous ovules. Affinities with the Magnoliaceae are suggested with Litocarpon combining characters of Magnolia and Liriodendron .
