For the first time, a phylogenetic analysis including all putative euparkeriid taxa is conducted, using a large data matrix analysed with maximum parsimony and Bayesian analysis. Using parsimony, the putative euparkeriid Dorosuchus neoetus from Russia is the sister taxon to Archosauria + Phytosauria. Euparkeria capensis is placed one node further from the crown, and forms a euparkeriid clade wi...

In order to compare the efficiency of morphological traits and molecular markers in distinguishing the Consolida species, molecular analysis using nrDNA ITS and cpDNA trnL-trnF with maximum parsimony and Bayesian methods were done in a total of 34 species and forma representing 28 species of Consolida, 6 species of Aconitella, plus two species of Delphinium and two species of Aconitum as out gr...

The Channichthyidae is a lineage of 16 species in the Notothenioidei, a clade of fishes that dominate Antarctic near-shore marine ecosystems with respect to both diversity and biomass. Among four published studies investigating channichthyid phylogeny, no two have produced the same tree topology, and no published study has investigated the degree of phylogenetic incongruence between existing mo...
