Fossil seedlings and seeds of an extinct Cercidiphyllum ‐like plant occur in the Paskapoo Formation (Late Paleocene) at Joffre Bridge near Red Deer, Alberta. Cotyledon and early seedling leaf stages are preserved in growth position. Morphological details of seedlings and seeds support a close relationship between the Paleocene fossils and extant Cercidiphyllum, and suggest that during the Upper Cretaceous and Tertiary (Paleogene) Cercidiphyllum ‐like plants were important early colonizers of open flood‐plain environments.
