Belongs within: Apiaceae.

The Saniculeae are a group of umbelliferous plants characterised by fruits with a minutely ornamented surface, two mericarps, and a non-lignified endocarp composed of a single cell layer (Liu et al. 2003). Members include the genus Eryngium, sea hollies, herbs with hairless, mostly spiny leaves and white or blue flowers borne in dome-shaped umbels with whorls of spiny basal bracts.

The Eutherapsida are the clade of synapsids uniting modern mammals with the Permian Dinocephalia. Members of the clade are characterised by a bowing of the zygomatic arch and increase in size of the temporal fenestra, together with loss of the olecranon ulnae and reduction of the fifth pedal digit to three phalanges.

The Kannemeyeriiformes are a cosmopolitan clade of dicynodonts known from the Triassic, some members of which reached the size of a modern cow. Members of the clade are united by a markedly enlarged preacetabular expansion of the iliac blade, a distinctly offset caput femoris on the femur, and an olecranon ulnae formed by a separate ossification (Maisch 2000).

Metatheria

Lower jaw of Pediomys, from here.


Belongs within: Boreosphenida.
Contains: Marsupialia.

The Metatheria are a clade of mammals including the total group of modern marsupials and all fossil taxa more closely related to marsupials than to other mammals. The earliest metatherians are known from the early Late Cretaceous of Eurasia and North America though they only survived into the Cenozoic in South America and Australia.

Synapomorphies (from Bi et al. 2014, for Sulestes + Marsupialia): Posterior vertical shelf of masseteric fossa connected to dentary condyle as thin crest along angular margin of mandible; dentary condyle continuous with semicircular posterior margin of dentary, condyle facing up due to up-turning of posterior-most part of dentary; molar with cristid obliqua present, contact closest to lowest point of protocristid; mesiolingual vertical crest of paraconid on lower molars forming a keel; entoconid near height of hypoconid; paraconid, metaconid, and entoconid on lower molars aligned; functional talonid basin of lower molars as long as wide; hypoconid/protoconid height ratio between 40% and 60%; stylar cuspule "C" (near ectoflexus) present on penultimate upper molar; wear facets 5 and 6 differentiated on labial face of entoconid; five upper incisors present; upper anterior-most incisor anteriorly projecting, separated from following teeth by diastema; body of calcaneus mediolaterally compressed at level of posterior calcaneoastragalar facet; calcaneal tubercle ventrally curved; lacrimal foramen on facial side of lacrimal; optic foramen not separated from sphenorbital fissure; incisive foramina intermediate in size.

Atlantogenata

Southern tamandua Tamandua tetradactyla, copyright Bernard Dupont.


Belongs within: Eutheria.
Contains: Dasypodidae, Folivora, Tubulidentata, Afrosoricida, Macroscelididae, Pan-Paenungulata.

The Atlantogenata are a clade of mammals supported by molecular data uniting the clades Xenarthra and Afrotheria. Xenarthra is the order of mammals containing the anteaters, sloths and armadillos, and is primarily found in South America. The name refers to the distinctive vertebrae of members of the clade. In older references this group was commonly referred to the Edentata, meaning 'toothless', but only the anteaters (Myrmecophagidae) are truly toothless; the sloths and armadillos retain enamelless back teeth. The armadillos and their extinct relatives in the Cingulata are characterised by dorsal armour formed from osteoderms covered in keratinous scales, that may be variously fused to form plates. The sloths and anteaters retain a uniform covering of thick hair. Anteaters have elongate snouts and tongues used for feeding on social insects.

The Afrotheria is a clade of mammals united by molecular analyses, though morphological support for the clade remains elusive. Most phylogenies support division of living afrotherians between the insectivorous taxa—Afrosoricida (golden moles and tenrecs), Macroscelididae (elephant shrews) and Orycteropus afer (aardvark)—and the herbivorous Paenungulata. Possible fossil afrotherians include the Ptolemaiida, a group of insectivorous or omnivorous mammals known from the Oligocene and Miocene of Africa. At least one ptolemaiidan, Kelba quadeemae, was probably about the size of modern coyote (Cote et al. 2007).

Folivora

Brown-throated sloth Bradypus variegatus, photographed by Stefan Laube.


Belongs within: Atlantogenata.
Contains: Ortotheriinae.

The Folivora, sloths, are a group of herbivorous mammals known from Central and South America. Living members of the group are arboreal though many fossil members were terrestrial and could reach massive sizes.
