Pygocephalomorph
The order Pygocephalomorpha is an extinct group of peracarid crustaceans. Pygocephalomorpha were abundant from the Carboniferous until their extinction in the Permian. Families The order contains extinct five families, and seven genera ''incertae sedis ' () or ''problematica'' is a term used for a taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa".

Karl Beurlen
Karl Beurlen (17 April 1901 – 27 December 1985) was a German paleontologist.Rieppel, Olivier. (2012). ''Karl Beurlen (1901-1985), Nature mysticism, and Aryan Paleontology''. ''Journal of the History of Biology'' 45: 253-299. Beurlen was born in Aalen. He attended University of Tübingen. He completed a PhD in 1923.Levit, Georgy S; Olsson, Lennart. (2007). ''Evolution on Rails Mechanisms and Levels of Orthogenesis''. In Volker Wissemann. ''Annals of the History and Philosophy of Biology 11/2006''. Universitätsverlag Göttingen. pp. 115-119 Beurlen was a proponent of orthogenesis and saltational evolution. He used the term ''metakinesis'' (coined by Otto Jaekel) to describe sudden changes of development in organisms. He also invented the term ''palingenesis'' as a mechanism for his orthogenetic theory of evolution. He was an assistant of Edwin Hennig.Stindl, Reinhard.
