Meyerosuchus [SEP] parent taxon
Meyerosuchus
Meyerosuchus is an extinct genus of mastodonsauroidean temnospondyl. Fossils have been found from the Early Triassic Hardegsen Formation in southern Germany. "Meyerosuchus" is present in late Olenekian deposits of the Middle Buntsandstein. The type species "M. fuerstenberganus" was named in 1966, although remains have been known since 1855. "Meyerosuchus" is closely related to "Stenotosaurus"; both genera are grouped in the family Stenotosauridae and the two genera may even be synonymous.
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
