The Use of Geological and Paleontological Evidence in Evaluating Plant Phylogeographic Hypotheses in the Northern Hemisphere Tertiary
TL;DR: The history of the climatic and geographic features of the Tertiary of the Northern Hemisphere agrees with many phylogenetically based phylogeographic hypotheses of living angiosperm genera but indicates that some hypotheses require reanalysis.

Life at the top of the greenhouse Eocene world--A review of the Eocene flora and vertebrate fauna from Canada's High Arctic
TL;DR: Early-middle Eocene (ca. 53-38 Ma) sediments of the Eureka Sound Group in Canada's Arctic Archipelago preserve evidence of lush mixed conifer-broadleaf rain forests, inhabited at times by alligators, turtles, and diverse mammals, including primates, tapirs, brontotheres, and hippo-like Coryphodon as mentioned in this paper.
Journal ArticleDOI
Seasonality, the latitudinal gradient of diversity, and Eocene insects
TL;DR: In insect diversity at McAbee is found to be more similar to La Selva than to Harvard Forest, with high species richness of most groups and decreased diversity of ichneumon wasps, indicating that seasonality is key to the latitudinal diversity gradient.
Journal ArticleDOI
The ecology of Cainozoic ferns
TL;DR: The ecology of Cainozoic ferns is documented (excluding that based only on nearest living relatives). Free-floating water Ferns (of the modern genera Azolla and Salvinia ) are widespread in the Cainogene as mentioned in this paper.

Early Tertiary Vegetation of Arctic Canada and Its Relevance to Paleoclimatic Interpretation
TL;DR: Early Tertiary fossil plants representing polar Arcto-Tertiary vegetation are found on Ellesmere and Axel Heiberg islands, northernmost of the Canadian Arctic Archipelago.
