Pholidotamorpha

 ( Paleocene First Appearances ) 

Pholidotamorpha ("pangolin-like forms") is a clade of Placentalia, mostly ant- and termite-eating Mammal that (partially) physically resemble Anteater and Armadillo. However, those aforementioned species are now placed in the order Xenarthra, along with ; Pholidotamorpha is now classified under the mirorder Ferae, which includes the order Carnivora (carnivorous mammals) and the pangolins (Pangolin) as well as the prehistoric order Palaeanodonta, containing only Extinction species.

Classification and phylogeny

History of taxonomy Both the Pholidota and Palaeanodonta orders were formerly placed with other orders of ant-eating mammals, most notably Xenarthra (, , , which they superficially resemble); some palaeontologists, throughout the history of zoology, have placed pangolins and palaeanodonts as a suborder, Pholidota, in the greater order Cimolesta, alongside the extinct family Ernanodontidae as a separate suborder Ernanodonta near it. However, this idea fell out of favor when it was determined that cimolestids were not truly placental mammals.

Newer genetic evidence indicates instead that the closest living relatives to Pholidota are the members of order Carnivora, together forming the mirorder Ferae.Mark S Springer, Christopher A Emerling, John Gatesy, Jason Randall, Matthew A. Collin, Nikolai Hecker, Michael Hiller, Frédéric Delsuc (2019) Odontogenic ameloblast-associated (ODAM) is inactivated in toothless/enamelless placental mammals and toothed whales In 2009, pangolins and palaeanodonts were together placed within the clade Pholidotamorpha. A 2012 study of new remains, found in Late Paleocene Stratum, have led to the assessment that extinct genus Ernanodon is closely related to another extinct genus, Metacheiromys, and is a member of the extinct order Palaeanodonta.
