Ferungulata ("wild beasts and ungulates") is a grandorder of placental mammals that groups together mirorder Ferae and clade Pan-Euungulata. It has existed in two guises, a traditional one based on morphological analysis and a revised one taking into account more recent molecular analyses. The Fereungulata is a sister group to the order Chiroptera (bats) and together they make clade Scrotifera.
General characteristics
According to 2022 study of Anne E. Kort, member of grandorder Ferungulata, in addition to their genetic similarities, share common synapomorphy in the lumbar vertebrae (the S-shaped postzygapophysis). In extant ferungulate mammals, this is known only within members of order Artiodactyla. However, this feature is found also in many extinct members of Ferungulata, including hyaenodonts, oxyaenids, mesonychids, arctocyonids and the stem-relatives of perissodactyls (like Cambaytherium).[4][5] This synapomorphy suggests that this may be basal to all Ferungulata and secondarily lost in modern members, like carnivorans and crown Perissodactyla. Previous study has shown that these S-shaped zygapophyses prevent torsion between vertebrae. As said in this study, it is possible this feature evolved in response to a need for stabilization in posterior spine as ribs became reduced. Also, in this and several other 2022 studies the extinct eutherians pantodonts, tillodonts and genus Deltatherium (family Deltatheriidae) are recognised as crown-group placental mammals,[4][6][7][8] who also possess S-shaped postzygapophysis like other members of Ferungulata.[4]
Classification and phylogeny
History of phylogeny
The traditional Ferungulata was established by George Gaylord Simpson in 1945.[1] It grouped together the extant orders Carnivora, Perissodactyla and Artiodactyla with the Tubulidentata and the superorder Paenungulata, as well as a number of orders known only from fossils.
Simpson established the grouping on the basis of morphological criteria, but this traditional understanding of Ferungulata has been challenged by a more recent classification, relying upon genetic criteria.[3][9][10] These studies separated his ungulate orders into two distinct placental groups, within Afrotheria and Laurasiatheria, respectively. The 'true' ungulates (mirorder Euungulata), Perissodactyla and Artiodactyla, are included in the revised group, along with the Carnivora, and with the addition of pangolins (order Pholidota), but the Tubulidentata and paenungulates are excluded. Although Simpson placed whales (Cetacea) in a separate cohort, recent evidence linking them to Artiodactyla would mean that they belong here as well. To reflect this difference, the revised clade is usually referred to as Fereungulata.
