A Palaeocene proboscidean from Morocco

  title={A Palaeocene proboscidean from Morocco},
  author={Emmanuel Gheerbrant and Jean Sudre and Henri Cappetta},
UNTIL recently, the oldest known Arabo-African fossils of the elephant order (Proboscidea) were scarce Moeritherium-like remains from the Middle Eocene epoch of Mali1 and Senegal2. In 1984 the discovery in Algeria of Numidotherium koholense 3 pushed back the record to the late Early Eocene. Here we report the discovery of a new genus in the late Palaeocene (Thanetian) epoch of Morocco (Ouled Abdoun Basin), about 7 million years older than Numidotherium. The new specimen is not only the oldest… Expand
Reptilian assemblages from the latest Cretaceous – Palaeogene phosphates of Morocco: from Arambourg to present time
Arambourg was the first to conduct methodical vertebrate palaeontological studies in the Oulad Abdoun and Ganntour phosphatic basins of Morocco between the 1930s and 1950s. As early as 1935, heExpand
Paleocene emergence of elephant relatives and the rapid radiation of African ungulates

The primitive morphology of Eritherium suggests a recent and rapid paenungulate radiation after the Cretaceous-Tertiary boundary, probably favoured by early endemic African paleoecosystems. Expand
A new large mammal from the Ypresian of Morocco: evidence of surprising diversity of early proboscideans
A parsimony analysis of Daouitherium suggests its intermediate phylogenetic position between the basal, small Phosphatherium and the large, more derived Numidotherium and Barytherium, and this supports the African origin of Proboscidea s.s. koholense. Expand
Early African Fossils Elucidate the Origin of Embrithopod Mammals
The cladistic analysis relates the Embrithopoda to crown paenungulates as the stem-group of the Tethytheria, which makes crown tethytherians restricted to extant elephant and sea cow orders, and supports a strictly African early radiation of the Paenungulate excluding the Phenacolophidae and Anthracobunia.

Further evidence of the African antiquity of hyaenodontid (‘Creodonta’, Mammalia) evolution
The discovery of Lahimia provides direct evidence for the antiquity of the African evolution of the Hyaenodontidae and the Koholiinae, which is representative of an old African endemic lineage, as initially recognized, is characterized by synapomorphies of LahIMia and Boualitomus, and also by a shared original prevallum/postvallid shearing.

A new Palaeocene Megalopidae (Teleostei, Elopomorpha) from the phosphate basins of Morocco
Abstract A new Megalopidae (Teleostei, Elopomorpha, Elopiformes), Protarpon boualii sp. nov., is described on the basis of two neurocrania gathered from the Lower Palaeocene (Danian) beds of theExpand
Ocepeia (Middle Paleocene of Morocco): The Oldest Skull of an Afrotherian Mammal
The remarkable character mosaic of Ocepeia makes it the first known “transitional fossil” between insectivore-like and ungulate-like afrotherians and the autapomorphic family Ocepeiidae supports the old – earliest Tertiary or Cretaceous – endemic evolution of placentals in Africa. Expand
New large-bodied mammals from the Late Oligocene site of Chilga, Ethiopia
Newly recovered fossil proboscideans and embrithopods from Chilga, Ethiopia are described and evaluated taxonomi− cally. They are dated to ca. 28–27 Ma (late Oligocene), temporally intermediateExpand
A new genus of Macroscelidea (Mammalia) from the Eocene of Algeria: a possible origin for elephant-shrews
The phylogenetic analysis suggests also that the Macroscelidea-Microhyus clade is closely related to the Proboscidea, and provides evidence for a macroscelid-tethytherian relationship. Expand
Reassessment of the Generic Attribution of Numidotherium savagei and the Homologies of Lower Incisors in Proboscideans
New data on its mandibular symphysis and, especially, on its lower incisors loci and morphology, bring new support to a hypothesis of homology between the lowerincisors of early proboscideans and the ever-growing lower tusks of the elephantiforms, which are identified here as di1 and i1. Expand

Aspects of cranial, dental, and postcranial anatomy are shown to be primitive in Numidotherium relative to Moeritherium and all other proboscideans. Expand
The role of phenacodontids in the origin of the modern orders of ungulate mammals
The role of the ancestral ungulates Phenacodontidae in the evolution of Perissodactyla, HyracoideA, Proboscidea, Sirenia, and Desmostylia is investigated on the basis of parsimony analysis of dental, cranial, and postcranial data. Expand

Allometric scaling in the dentition of primates and prediction of body weight from tooth size in fossils.
Regressions based on tooth size in generalized primates yield reasonable estimates of body weight, but much remains to be learned about tooth size and body size scaling in more restricted systematic groups and dietary guilds. Expand
