Compsodon [SEP] parent taxon
Compsodon
Compsodon is an extinct genus of dicynodont belonging to the anomodont group Emydopoidea. Fossils have been found in South Africa and Zambia.
"Compsodon helmoedi" was originally described by Egbert Cornelis Nicolaas van Hoepen in 1934 on the basis of a single specimen from late Permian deposits in the Karoo Basin of South Africa. Two additional specimens from South African museum collections and three new specimens from the Luangwa Basin of Zambia have elucidated new aspects of the morphology of this species and indicate that it occurred in upper Cistecephalus and lower Daptocephalus
Taxon in disguise
In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade.
While the term is from bacteriology, parallel examples are found throughout the tree of
