Premise of research. Phylogenetic relationships of Araucariaceae (Coniferophyta, Araucariales) are revised on the basis of the first combined data matrix for the family. Methodology. Taxon sampling includes 39 ingroup species (31 extant, 8 fossils) and outgroup species of all the remaining conifer families. Five fossil Araucaria species, one species of the genus Araucarites, and two species of the extinct genera Wairarapaia and Emwadea were included in the analyses. Character sampling includes… 
Numerical analysis of the inter-relationships of some extinct and extant tax of Araucariaceae
TLDR
The inter-relationships between extant and selected extinct taxa of Araucariaceae were explored using thirty morphological and anatomical characters using phenetic and cladistic methodology which revealed there was close agreement between the two when applied to extant taxa but not to extant plus extinctTaxa.
Incorporating fossils into the Pinaceae tree of life.
TLDR
A robust phylogenetic hypothesis for the main lineages of Pinaceae is emerging after it was found that the placement of most fossils was sensitive to the method of phylogenetic reconstruction when analyzing them singly with the extant species.
Defying death: incorporating fossils into the phylogeny of the complex thalloid liverworts (Marchantiidae, Marchantiophyta) confirms high order clades but reveals discrepancies in family‐level relationships
TLDR
A total‐evidence analysis of Marchantiidae incorporating fossils challenges the widespread notion that bryophyte fossils are problematic for phylogenetic inference.
Araucaria lefipanensis (Araucariaceae), a new species with dimorphic leaves from the Late Cretaceous of Patagonia, Argentina.
TLDR
The new species shows evidence of mosaic evolution, with cone scale complexes morphologically similar to section Eutacta and leaves similar to the sections of the broad-leaved clade, constituting a possible transitional form between these two well-defined lineages.
First phylogenetic analysis of the family Neriidae (Diptera), with a study on the issue of scaling continuous characters
TLDR
The first comprehensive phylogenetic analysis of the Neriidae is performed, including 48 species from all biogeographic regions inhabited, as well as five species of Micropezidae and one Cypselosomatidae as outgroups, and confirms the monophyly of the family and of most its genera.
Ovulate Cones of Schizolepidopsis ediae sp. nov. Provide Insights into the Evolution of Pinaceae
Premise of research. The extinct conifer genus Schizolepidopsis is characterized by deeply bilobed ovuliferous scales bearing two adaxial seeds. Although it is frequently placed in Pinaceae, the
New Insights into the Evolution of Mucilage Cells in Araucariaceae: Araucaria violetae sp. nov. from the Early Cretaceous Araripe Basin (Northeast Brazil)
Premise of research. Araucariaceae are currently disjunctively distributed over the Southern Hemisphere, dominating only some restricted habitats. In contrast, fossil representatives of this group
Rooting morphologically divergent taxa – slow-evolving sequence data might help
TLDR
The phylogeny of a highly divergent group of mosses, class Polytrichopsida, is revisited and it is indicated that large size and complexity of the gametophyte have evolved independently in several lineages.
Phylogeny and Divergence Times of Gymnosperms Inferred from Single-Copy Nuclear Genes
TLDR
This study uses LFY and NLY, two single-copy nuclear genes that originated from an ancient gene duplication in the ancestor of seed plants, to reconstruct the phylogeny and estimate divergence times of gymnosperms based on a complete sampling of extant genera and strongly supports cycads as the basal-most lineage of Gymnosperms rather than sister to Ginkgoaceae.
First pentasetacid mite from Australasian Araucariaceae: morphological description and molecular phylogenetic position of Pentasetacus novozelandicus n. sp. (Eriophyoidea, Pentasetacidae) and remarks on anal lobes in eriophyoid mites
TLDR
Molecular phylogenetic analyses of full-length D1–D2 eriophyoid sequences, including GenBank sequences and newly generated sequences of pentasetacids, confirmed the monophyly of PentAsetacidae but failed to resolve the basal phylogeny of Eriophyoidea.

Phylogenetic relationships within Araucariaceae based on rbcL gene sequences.
TLDR
Phylogenetic trees determined by the parsimony method indicate that Araucariaceae are well defined by rbcL sequences and also that the monophyly of Agathis or Araucaria is well supported by high bootstrap values.
Phylogenetic Relationship Within Genus Araucaria (Araucariaceae) Assessed by Means of AFLP Fingerprints
TLDR
Both rbcL sequence data and AFLP analyses do not support section Bunya as one of the oldest sections within genus Araucaria, as suggested by the fossil record and the utility of AFLP markers for phylogenetic analyses is discussed.
Phylogenetic relationships and divergence times of the family Araucariaceae based on the DNA sequences of eight genes
TLDR
DNA sequences obtained from this study and GenBank were used for constructing the molecular phylogenetic trees of Araucariaceae, indicating that the phylogenetic relationships among the three genera of this family should be ((Wollemia, Agathis), Araucaria).
Phylogenetic Position of Hoop Pine (Araucaria cunninghamii)
TLDR
This study suggests that A. cunninghamii was the most recent Araucaria species to evolve, with the Papua New Guinean provenances undergoing the fastest evolutionary changes.
Phylogenetic relationships of conifers inferred from partial 28S rRNA gene sequences.
TLDR
Cl cladistic analyses using a new data set obtained from 28S rRNA gene sequences strongly support the monophyly of conifers including Taxaceae and suggest that the common ancestor of these families, both having the greatest diversity in the Southern Hemisphere, inhabited Gondwanaland.
The Araucariaceae: An evolutionary perspective
TLDR
Well-preserved Bunya section cones from Europe, South America and India suggest that this section was widespread in both hemispheres during the Jurassic, and that the section Bunya be retained in current taxonomic schemes even though it contains only one extant species.
AFLP markers provide insights into the evolutionary relationships and diversification of New Caledonian Araucaria species (Araucariaceae).
TLDR
It is shown that genetic divergence among the present New Caledonian Araucaria species is low, suggesting recent diversification rather than pre-existence on Gondwana, and hypothesize that speciation is ongoing and/or there are cryptic species in some genetically (sometimes also morphologically) divergent populations.
Implications of fossil conifers for the phylogenetic relationships of living families
TLDR
Differences between modern conifer families are due mainly to their divergence from different Paleozoic ancestors.

TLDR
Results imply that glossophytes originally had glossopterid-like leaves and bract-sporophyll complexes, which were transformed into carpels with bitegmic ovules in angiosperms, but reduced to single, terminal Ovules in Gnetales; flowers arose independently in the two lines.
