TL;DR: A high-resolution sampling protocol was used to study the microflora from a two-meter thick siltstone unit located between two prominent coals representing Metasequoia-dominated swamp forests from the middle Eocene (ca. 45 million years old) Buchanan Lake Formation at Napartulik, Axel Heiberg Island, Nunavut, Canada.

A survey of species assigned to the fossil pollen genus Anacolosidites
TL;DR: The present study identifies the published reports of the fossil species that probably represent positive occurrences of Olacaceae pollen in the fossil record and suggests that the newly emended genus Anacolosidites may be used as a stratigraphic marker for tropical or megathermal climatic conditions.

Evolutionary considerations of the presence of both morphophysiological and physiological seed dormancy in the highly advanced euasterids II order Dipsacales
Jerry M. Baskin,Siti N. Hidayati,Carol C. Baskin,Jeffrey L. Walck,Zhengying Huang,Ching-Te Chien +5 more
TL;DR: Molecular dating indicates that the ages of dipsacalean lineages with MPD and PD are older than those indicated by the fossil evidence, and phylogeny and kind of seed dormancy in the highly evolutionarily advanced order Dipsacales shows that MPD occurs throughout all clades except the most advanced one, Valerina.

The Pliocene flora of Frankfurt am Main, Germany: taxonomy, palaeoenvironments and biogeographic affinities.
TL;DR: The Pliocene flora of Frankfurt am Main described by Karl Madler during the first half of the twentieth century is a key flora for the European pliocene as mentioned in this paper, showing that the European flora was more diverse in woody species shortly before the onset of major Pleistocene glaciations than today.
