Pholidotamorpha ("pangolin-like forms") is a clade of placental mammals from mirorder Ferae that includes the order Pholidota (the pangolins) and extinct order Palaeanodonta. [1]
Classification and phylogeny
History of taxonomy
In the past both orders, Pholidota and Palaeanodonta, were formerly classified with various other orders of ant-eating mammals, most notably Xenarthra ( armadillos, sloths and true anteaters) which they superficially resemble. Some palaeontologists in past placed pangolins and palaeanodonts as a suborder "Pholidota" in order Cimolesta, alongside the extinct family Ernanodontidae as a separate suborder Ernanodonta near it, though this idea has fallen out of favor since it was determined that cimolestids were not placental mammals. [2]
However, newer genetic evidence indicates the closest living relatives to order Pholidota are the members of order Carnivora, and together they form the mirorder Ferae. [3] [4] [5] In 2009, pangolins and palaeanodonts were together placed within clade Pholidotamorpha. [1] A 2012 study from new remains found in Late Paleocene Mongolian strata have led to the assessment that extinct genus Ernanodon is closely related to extinct genus Metacheiromys and being a member of the extinct order Palaeanodonta. [6]
