Phylogenetically, Oregonichthys is either sister to Tiaroga of the Gila and San Pedro Rivers of the American Southwest (based on mtDNA) or part of a polytomy
(based on nuclear DNA) including Tiaroga, Rhinichthys, and numerous eastern genera (Simons and others 2003; Buffalino and Mayden 2010; Smith and others 2017).
mongolicus are grouped in two separate clusters, which stand in a polytomy
None of the sequences from "Group A" matched a particular species and, due to weak nodal support, formed a polytomy
with the Codiaceae and Bryopsidaceae (Fig.
The MP analysis returned a polytomy

that include all thalassophonean pliosaurids plus Marmornectes candrewi (Figure 8A).
Based on molecular data the polytomy
of Ciconia may reflect a rapid process of speciation, because the trees of consensus have their branches collapsed (generating polytomies), when the trees from where they came (hybridisation DNA-DNA and analysis of cytochrome b), have the branches short (SLIKAS, 1997).
This topology shows a polytomy
among the Fusarium genus belonging to the Gibberella fujikuroi complex, but it does show phylogenetic difference with Fusarium proliferatum, this being different from the polytomic sequences (with high support: BV>75 PP>0.95).
The maximum likelihood tree had a negative log likelihood of-2020.75868 and placed the samples in a polytomy
of Anatrachyntis badia BOLD vouchers (Fig.
Asketaspis is in a polytomy
