Acer kenaicum

Acer kenaicum is an extinct maple species in the family Sapindaceae described from a pair of fossil leaves and a samara.

[1] Acer kenaicum is known from a pair of leaf specimens and a solitary samara which were recovered from two different outcrops of Early Oligocene strata.

At the time of description, all three were preserved in the paleobotanical collections housed at the National Museum of Natural History, part of the Smithsonian.

The specimens were studied by paleobotanists Jack A. Wolfe of the United States Geological Survey, Denver office and Toshimasa Tanai of Hokkaido University.

Wolfe and Tanai published their 1987 type description for A. kenaicum in the Journal of the Faculty of Science, Hokkaido University.
