Dating the subsidence history of the North Atlantic Land Bridge (NALB) is crucial for understanding intercontinental disjunctions of northern temperate trees. Traditionally, the NALB has been assumed…

The main finding is that the Miocene flora of Iceland belongs to a widespread Neogene northern hemispheric floral type including plants whose representatives are restricted to East Asia, North America and to western Eurasia at the present time.
The Biogeographic History of Iceland – The North Atlantic Land Bridge Revisited

Plants lacking long distance dispersal mechanisms required a functioning land bridge to colonize Iceland, a route provided by the North Atlantic Land Bridge (NALB). During the Cainozoic, the NALB,…

Lythrum and Peplis from the Late Cretaceous and Cenozoic of North America and Eurasia: new evidence suggesting early diversification within the Lythraceae.

- 1 November 2011
The findings add vital information for the time of origin of the Lythraceae and suggest a higher diversity within the family, and indicate that the distribution of particular genera during the Cretaceous was wider than previously thought.
Floristic turnover in Iceland from 15 to 6 Ma – extracting biogeographical signals from fossil floral assemblages
- F. Grímsson, T. Denk

- 1 September 2007
The composition of floras and dispersal mechanisms indicate that Iceland was connected both to Greenland and to Europe in the early Middle Miocene, allowing transcontinental migration and the extinction of thermophilous taxa.

Abstract The fossil record provides good evidence for the minimum ages of important events in the diversification and geographic spread of Asteridae, with earliest examples extending back to the…
Fagaceae pollen from the early Cenozoic of West Greenland: revisiting Engler’s and Chaney’s Arcto-Tertiary hypotheses

Comparison with coeval or older mid-latitude records of modern lineages of Fagaceae shows thatmodern lineages found in western Greenland and Axel Heiberg likely originated at lower latitudes, corroborate earlier findings that Fag growers were a dominant element at high latitudes during the early Cenozoic.
