Hydaspitherium [SEP] parent taxon
Hydaspitherium
Hydaspitherium is an extinct genus of giraffid artiodactyls.
Giraffids are represented in the late Miocene of the Siwaliks by large Sivatheriinae such as "Sivatherium", "Bramatherium", "Helladotherium", and "Hydaspitherium". "Hydapitherium" has been proposed to be synonymous with "Bramatherium". "H. megacephalum" is restricted to the Dhok Pathan Formation (, paleocoordinates ) in northern Pakistan.
Four separate species of "Hydaspitherium" were described more than a century ago, but concluded that their differences can be
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
