More than 200 specimens of Limnobiophyllum scutatum (Dawson) Krassilov have been recovered from lacustrine claystones in the Paleocene Paskapoo Formation near Red Deer, Alberta. The plant was a floating, aquatic angiosperm with helically arranged, ovate leaves attached in small rosettes. Rosettes are interconnected by stolons and bear simple adventitious roots as well as larger branching roots that appear to have vascular tissue. Leaves are pubescent, aerenchymatous, with 12-14 campylodromous…

Cobbania corrugata gen. et comb. nov. (Araceae): a floating aquatic monocot from the Upper Cretaceous of western North America.
TLDR
A floating aquatic monocot from 71 whole plants and several isolated leaf fragments from Upper Cretaceous oxbow lake sediments in the Dinosaur Park Formation, Alberta, Canada is described, revealing a third possible origin of the floating aquatic habit within Araceae.
Araceae from the Early Cretaceous of Portugal: evidence on the emergence of monocotyledons.
TLDR
The new fossil provides unequivocal evidence of monocots in early angiosperm assemblages that also include a variety of key "magnoliid" lineages but only a limited diversity of eudicots.
Reconstructing the Callianthus plant–An early aquatic angiosperm from the Lower Cretaceous of China
TLDR
Morphological analysis indicates that Callianthus was an aquatic plant, as Archaefructus, suggesting that angiosperms might have explored aquatic habitats by the end of Barremian in the Early Cretaceous.
Oligocene Limnobiophyllum (Araceae) from the central Tibetan Plateau and its evolutionary and palaeoenvironmental implications
TLDR
Reconstruction of vegetative and reproductive character evolution confirms that Limnobiophyllum possessed intermediate characters, especially for infructescences, between the subfamilies Lemnoideae and Aroideae, and sheds new light on the evolutionary history of the family Araceae.
Morphology, affinities and phytogeographic history of Porosia Hickey in the Cretaceous and Paleocene of North America and Asia
ABSTRACT Morphology and anatomy of the extinct angiosperm fruit, Porosia verrucosa (Lesqueruex) Hickey, are documented in detail based on various modes of preservation including molds, casts, and…
Morphology and paleoecology of Ricciopsis speirsae sp.nov. (Ricciaceae), a fossil liverwort from the Paleocene Joffre Bridge locality, Alberta, Canada
TLDR
Ricciopsis speirsae is the first ricciaceous fossil to be described from North America and the first of Paleocene age worldwide.
In situ fossil seedlings of a Metasequoia-like taxodiaceous conifer from Paleocene river floodplain deposits of central Alberta, Canada
TLDR
Fossil seeds and seedlings of a Metasequoia-like taxodiaceous conifer occur in Paleocene deposits at the Munce's Hill and Gao Mine localities of central Alberta, Canada and reveal that both Joffrea and this extinct taxodi Jurassic conifer were early colonizers of North American floodplain communities at the beginning of the Tertiary.
An aquatic angiosperm of the Late Cretaceous, Mendoza Province, central-western Argentina: its phylogenetic position in Araceae
TLDR
The phylogenetic relationships of the new fossil with other members of Araceae suggest that N. crenae is closely related to the fossil Aquaephyllum auriculatum, and this fossil constitutes the southernmost record of a floating aquatic aroid.
Late Cretaceous Aquatic Plant World in Patagonia, Argentina
TLDR
A reconstruction of the aquatic plant paleocommuniy is provided based on the distribution of the fossils along a freshwater horizon within the La Colonia Formation, constituting the first reconstruction of a Cretaceous aquatic habitat for southern South America.
Fossil Araceae from the Upper Cretaceous of Patagonia, Argentina, with implications on the origin of free-floating aquatic aroids
TLDR
A new fossil genus and species is described, Aquaephyllum auriculatum, and the presence of Pandaniidites pollen grains from La Colonia Formation, Patagonia, Argentina is reported on, which are the first fossil record of lemnaceous leaves and the oldest record for PandaniIDites pollen for the Southern Hemisphere respectively.

Growth and reproductive biology of Joffrea speirsii gen. et sp. nov., a Cercidiphyllum-like plant from the Late Paleocene of Alberta, Canada
TLDR
Evidence for treating the different organs under a single binomial includes attachment of inflorescences and leaf petioles to long and short shoot systems, morphological intermediates between carpels and follicles, follicles preserved expelling seeds, seeds preserved during germination, stages in seedling development, similarity between seedling and adult foliage, and constant field association.
New Paleocene genus and species of smelt (Teleostei: Osmeridae) from freshwater deposits of the Paskapoo Formation, Alberta, Canada, and comments on osmerid phylogeny
TLDR
The new smelt is characterized by a long, toothed mandible and premaxilla and a slender, toothless maxilla, in combination with the virtual absence of teeth inside the mouth and a distinct second ural centrum.
Platanaceous plants from the Paleocene of Alberta, Canada
TLDR
The reconstruction of the Joffre plane tree is the second “whole plant” reconstruction from theJoffre Bridge locality and can be included among the best known Paleocene angiosperms.

Phylogenetic analysis of rbcL sequences identifies Acorus calamus as the primal extant monocotyledon.
TLDR
P phylogenetic analyses based on DNA sequences of the plastid locus rbcL in which Acorus calamus, an herb with unspecialized floral features and of uncertain affinities, is supported as a member of the oldest extant lineage of monocotyledons are presented.

In Situ Cercidiphyllum-like Seedlings from the Paleocene of Alberta, Canada.
TLDR
Morphological details of seedlings and seeds support a close relationship between the Paleocene fossils and extant Cercidiphyllum, and suggest that during the Upper Cretaceous and Tertiary (Paleogene)Cercidzphyllum-like plants were important early colonizers of open flood-plain environments.
