Baraminological Analysis of the Caseidae (Synapsida: Pelycosauria)

M Aaron


Previous creationist research has indicated that the level of the created kind, or holobaramin, is at or near the family level in living organisms.  However, little research has been done to expand this concept to fossil organisms.  In this study, a family of pelycosaur reptiles, Caseidae, was analyzed through the use of statistical baraminology.  Pelycosauria is a grouping of basal synapsids or “mammal-like reptiles” considered paraphyletic by conventional researchers.  Since pelycosaurs are thought to be the distant ancestors to mammals by the mainstream, scientific community, it is imperative that creationists analyze their relationships through baraminology.  Caseids all share a number of characteristics with each other, and superficially appear to be discontinuous with other organisms.  Thus, the author hypothesized that continuity should exist within the Caseidae, and that there should be discontinuity between caseid taxa and non-caseid taxa.  A cladistic study from “Cranial Anatomy of Ennatosaurus tecton (Synapsida: Caseidae) from the Middle Permian of Russia and the Evolutionary Relationships of the Caseidae” by Maddin, Sidor, and Reisz (2008) was reanalyzed through baraminic distance correlation (BDC) and multidimensional scaling (MDS).
