Canadian fossil palms

Fossil palms from Canadian sites have been known since Sir. J.W. Dawson (1883) when he described a feather palm (Phoenicites imperialis) from Upper Cretaceous rocks on Vancouver Island (see also Johnson & Hebda, 2015), and a fan palm (Sabalites campbelli) from Eocene rocks from Burrard Inlet in Vancouver, British Columbia (Newberry, 1863; Dawson 1895).

Much later, Diane Erwin and Ruth Stockey (1994) described the 3-dimensionally preserved small swamp palm, Uhlia allenbyensis from the early Eocene Princeton Chert, BC.

There have been anecdotal references to these early records, but also mention made of Cretaceous and Paleocene palms from Alberta and Saskatchewan (e.g., McIver 2002; Aulenback, 2009). Many of these Canadian fossil palms remain undescribed, and reviews of the palm fossil record solely list the Dawson (1883) Cretaceous record, and Uhlia allenbyensis.

Working with PhD student Christopher West and Australian colleague John Conran (e.g., Greenwood & Conran, 2000; Conran & Rozefelds, 2003), I am describing the Cretaceous to Eocene fossil palms from BC, Alberta and Saskatchewan (e.g., Greenwood & West 2017; Greenwood & Conran In press). Recent work on the Paleocene Kanaka Creek flora near Vancouver has revealed additional palm leaf fossils (Mathewes et al. 2019).

The research on the Alberta palm fossil received strong support from colleagues at the Royal Tyrrell Museum of Palaeontology, the Royal Alberta Museum, and the University of Alberta Paleontology Museum. Work on the BC palms has been aided by colleagues at the Geological Survey of Canada in Ottawa, and the Royal BC Museum in Victoria, BC.

In addition, working with Tammo Reichgelt (Lamont Doherty Earth Observatory of the University of Columbia, NY; NB: @ University of Connecticut from Sept. 2019) we are precisely determining the climatic limits for the natural distribution of palms globally, to refine the so-called ‘palm line’ (Wing & Greenwood 1993; Greenwood & Wing 1995; Reichgelt et al. 2018) used to constrain Paleogene climate estimates of temperature.

This research is funded by a NSERC Discovery Grant.
