Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

The Anatomical Record, EarlyView.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Taxon sampling revisited

Nature, 1999
Phylogenies that include long, unbranched lineages can be difficult to reconstruct. This is because long-branch taxa (such as rapidly evolving species) may share character states by chance more often than more closely related taxa share derived character states through common ancestry1. Despite Kim's warning that added taxa can decrease accuracy2, some

The Taxon Concept: Is it Taxonic?

Psychological Reports, 2008
The question of whether the concept of a “taxon” (a nonarbitrary latent category) is itself categorical, or is a matter of degree, has lain dormant within taxometrics. I analyze the problem conceptually. Part of the meaning of “taxon,” I hold, goes beyond the manifest statistical properties of admixed probability distributions; any of certain forms of
