similar leaf and fruit associations in the older Klondike Mountain Formation of Washington state, Manchester et al considered it possible that the leaves and fruits were produced by the same plant. At the time of description however the two organs had not been found in connection, and so where described under separate names. The fruits are over double the size of the older Ypresian age Trochodendron drachukii fruits from the McAbee Fossil Beds in Canada. Description Trochodendron rosayi fruits are born on pedicels sprouting from a thick central stalk. The fruits have a globose to turbinate outline, with a narrow base that flares out towards the apex. The tops of the fruits are rounded with approximately ten locular slits joining at the fruit apex to from a polygonal opening when the mature fruits dehisced. The locular slits form just above the straight to slightly outwardly curved persistent styles which sprout from the fruit 1/3 of the way below the apex. Below the styles are triangular flattened structures that were likely the flower nectaries. Encircling the basal section of the fruits are an estimated 25 scars left by the shed stamens.
