Recent innovations in three-dimensional computer graphics have enabled reconstruction of a 45 million-year-old fossil forest on Axel Heiberg Island, Canadian Arctic Archipelago. Detailed study of one of the well-exposed fossil forest horizons formed the basis for a blueprint showing the position and diameter of each exposed stump. The results of this study provide insight into stand structure and density of this high-latitude fossil forest through visualization of the spatial configuration of the stand. The data from the fossil forest were calibrated with measurements taken from extant trees of the same species growing at Tsuruoka Campus, Yamagata University, Japan. The results are presented here as three-dimensional computer graphic representations and indicate that this Axel Heiberg Island fossil forest was a multi-storied climax stand with seedlings and juvenile trees growing under a forest canopy.
