Naming taxa is an important endeavor in the documentation of life by systematists, whether it is conducted in the context of traditional rank-based classification or within a phylogenetic framework. Proponents of the phylogenetic approach distinguish between the diagnosis of a group and its definition (Ghiselin, 1984; Rowe, 1987, 1988), and this distinction forms the basis for a phylogenetically based method of naming taxa formerly referred to as Phylogenetic Taxonomy (de Queiroz and Gauthier…

Are the linnean and phylogenetic nomenclatural systems combinable? Recommendations for biological nomenclature.

It is seen as essential that species binomen, including the formal rank of genus, are retained, and species should continue to be linked to type specimens and the use of other formal ranks should be minimized.

Assembling the history of the Parareptilia: phylogeny, diversification, and a new definition of the clade

The results show that a significant increase in diversification rate could be recorded only among Triassic procolophonoids, making it difficult to interpret evolutionary novelties such as herbivory or impedance-matching hearing as being key innovations that might have driven diversification.

To name or not to name: Criteria to promote economy of change in Linnaean classification schemes.

It is concluded that not all TNCs lead to equally informative and stable taxonomies and provides a workflow scheme to guide the procedure of taxonomic decisions concerning the creation or modification of supraspecific classifications.

Taxonomic Committee of the Societas Europaea Herpetologica

According to the list, 301 species (95 amphibians, 15 chelonians, including six species of sea turtles, and 191 squamates) occur within the expanded geographical definition of Europe, which includes 14 non-native species.

Response: A Reassessment of the Taxonomic Position of Mesosaurs, and a Surprising Phylogeny of Early Amniotes

The early amniote clade Mesosauridae has long been of interest to scientists, primarily due to the members of the clade being the oldest secondarily aquatic tetrapods and their role as a line of

Revised anatomy, taxonomy and biostratigraphy of Notochampsa istedana Broom, 1904, a Lower Jurassic crocodyliform from the Clarens Formation (Stormberg Group), and its implications for early crocodyliform phylogeny

Notochampsa istedana is the youngest known occurrence of a crocodylomorph (and vertebrate body fossil) from the Karoo Basin of South Africa, and the phylogenetic analysis recovers it as sister to Orthosuchus, in a monophyletic Notochampsidae.

The PhyloCode: a critical discussion of its theoretical foundation

It is shown that the thesis of “rigid designation” if deployed in taxonomy introduces a new essentialism into systematics, which is exactly what the PhyloCode was designed to avoid.

Stop the Abuse of Time! Strict Temporal Banding is not the Future of Rank-Based Classifications in Fungi (Including Lichens) and Other Organisms

The temporal banding approach to classification of Lecanoromycetes (lichenized Fungi) is critically revised, pointing out strengths and flaws, and “best practice” recommendations are given how to employ this technique properly and with care to improve existing classifications while avoiding unnecessary disruptions.

The Ambiguous Use of the Prefix 'Pan' in Arthropod Systematics

It is emphasised the importance of unambiguous group names in order to provide a precise scientific communication and to avoid confusion in the systematics of organisms.

The first record of a nyctiphruretid parareptile from the Early Permian of North America, with a discussion of parareptilian temporal fenestration

The Richards Spur Locality of Oklahoma, USA, long known for its highly diverse Early Permian terrestrial tetrapod assemblage, is particularly interesting for the presence of many endemic taxa. The



Meaning of the name tetrapoda in the scientific literature: an exchange.

This exchange stems from an on-going debate between advocates of crown clade and apomorphybased definitions of widely used taxon names, and aims at clarifying the respective advantages of both types of definitions.


Why phylogenetic nomenclature is a good thing for paleontology and ways in which the community can make the transition from typological to evolutionary systems while minimizing confusion are suggested.

Species names in phylogenetic nomenclature.

Here, 13 methods for naming species in the context of phylogenetic nomenclature are contrasted with each other and with Linnaean binomials and a fundamental dichotomy among the proposed methods distinguishes those that retain the entire binomial of a preexisting species name fromThose that retain only the specific epithet.

A review of criticisms of phylogenetic nomenclature: is taxonomic freedom the fundamental issue?

It is argued that the form of taxonomic freedom inherent in phylogenetic nomenclature is appropriate to phylogenetic taxonomy, in which taxa are considered historical entities that are discovered through phylogenetic analysis and are not human constructs.

Definition and Diagnosis in the Phylogenetic System

If taxa are viewed as individuals in the phylogenetic system, Ghiselin (1984) quite rightly pointed out that they may not possess defining characters because characters may transform without affecting the individuality of the taxon.

Phylogeny as a Central Principle in Taxonomy: Phylogenetic Definitions of Taxon Names

Defining the names of taxa in terms of common ancestry, that is, using phylogenetic definitions of taxon names, departs from a tradition of character-based definitions by granting the concept of


The importance of the critical fossils seems to reside in their relative primitive‐ness, and the simplest explanation for their more conservative nature is that they have had less time to evolve.

Definitions in phylogenetic taxonomy: critique and rationale.

A general rationale for the formulation and placement of taxonomic definitions in phylogenetic taxonomy is proposed, and commonly used terms such as "crown taxon" or "node-based definition" are more

Feathered Dinosaurs, Flying Dinosaurs, Crown Dinosaurs and the Names "Aves"

This work proposes a taxonomy that resolves current nomenclatural ambiguity by using a different name for each of the clades that everyone wants to talk about—namely, those composed of bird-line archosaurs, the feathered dinosaurs, the flying dinosaurs, and the crown dinosaurs.
