Prosynthetoceras [SEP] parent taxon
Prosynthetoceras
Prosynthetoceras is an extinct genus of Artiodactyla, of the family Protoceratidae, endemic to North America. It lived during from the Early to Middle Miocene 20.6—13.6 Ma, existing for approximately . In appearance, "Prosynthetoceras" looked much like "Syndyoceras", "Kyptoceras", and "Synthetoceras" with three horns, one on the snout, and two above the eyes.
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
