The Algerian localities of the Gour Lazib area (Early or early Middle Eocene) have yielded an important mammalian fauna. The Hyaenodontida are well represented in this fauna: three species–two are new– are reported. The genus Glibzegdouia, which has been previously described as a possible Carnivora, is now clearly referred to the Hyaenodontida. It appears morphologically close to Masrasector and Dissopsalis. A new genus, Furodon, is described. It appears morphologically close to the oldest… 

Hyainailourine and teratodontine cranial material from the late Eocene of Egypt and the application of parsimony and Bayesian methods to the phylogeny and biogeography of Hyaenodonta (Placentalia, Mammalia)

It is found that Hyaenodonta most likely originated in Europe, rather than Afro-Arabia, and it is proposed that the superfamily Hyainailouroidea be used to describe this relationship.

New fossils of Hyaenodonta (Mammalia) from the Eocene localities of Chambi (Tunisia) and Bir el Ater (Algeria), and the evolution of the earliest African hyaenodonts

We present and describe new fossils from the Eocene North African localities of Chambi (Tunisia; late Ypresian or early Lutetian) and Bir el Ater (Algeria; latest Bartonian or earliest Priabonian).

The hyaenodonts (Mammalia) from the French locality of Aumelas (Hérault), with possible new representatives from the late Ypresian

The carnivorous mammals from the Eocene French locality of Aumelas are described and appear to be morphologically similar to hyaenodonts from late Ypresian to early Lutetian of the northwestern Europe (European mammal reference level MP10 and MP11).

New proviverrines (Hyaenodontida) from the early Eocene of Europe; phylogeny and ecological evolution of the Proviverrinae

It is indicated that the Proviverrinae diversified greatly during the Early Eocene Climatic Optimum and show a general trend towards specialization throughout the Eocene.

The first North American Propterodon (Hyaenodonta: Hyaenodontidae), a new species from the late Uintan of Utah

Identification of a North American species of Propterodon and an Asian Apataelurus increases the similarity of North American Uintan and Asian Irdinmanhan faunas and suggests that there was substantial exchange of carnivorous fauna during the late middle Eocene.

New Dental Elements of the Oldest Proviverrine Mammal from the Early Eocene of Southern France Support Possible African Origin of the Subfamily

This new material shows that, by the beginning of the early Eocene, proviverrines already displayed their typical combination of dental features characterized by the presence of a large paraconid and entoconid on p4, and supports the divergence of the two subfamilies by this time.

Latest Early-early Middle Eocene deposits of Algeria (Glib Zegdou, HGL50), yield the richest and most diverse fauna of amphibians and squamate reptiles from the Palaeogene of Africa

HGL50 is a latest Early-early Middle Eocene vertebrate-bearing locality located in Western Algeria. It has produced the richest and most diverse fauna of amphibians and squamate reptiles reported

A New Large Hyainailourine from the Bartonian of Europe and Its Bearings on the Evolution and Ecology of Massive Hyaenodonts (Mammalia)

The first phylogenetic analysis of hyainailourines is performed to determine the systematic position of K. langebadreae and to understand the evolution of the group that includes other massive carnivores, demonstrating that Hemipsalodon, a North American taxon, is a hyainailsourine and is closely related to European Paroxyaena.

Craniodental and Postcranial Morphology of Indohyaenodon raoi from the Early Eocene of India, and Its Implications for Ecology, Phylogeny, and Biogeography of Hyaenodontid Mammals

The most comprehensive phylogenetic analysis of Hyaenodontidae to date is presented, which corroborates this relationship but finds South Asian hyaenodonids to be the stem of a group that includes most African hyaENodontids.



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.

New proviverrine genus from the Early Eocene of Europe and the first phylogeny of Late Palaeocene–Middle Eocene hyaenodontidans (Mammalia)

The probable African origin of the Hyaenodontida supports the diphyletism of ‘Creodonta’ and abandonment of this taxon.


Orienspterodon represents the earliest fossil records of Hyaenaelurinae, and some features indicate an early branching of this genus from the other hyaenaeurines.

New discoveries of hyaenodontids (Creodonta, Mammalia) from the Pondaung Formation, middle Eocene, Myanmar -paleobiogeographic implications

The alleged paleobiogeographic connection between Asia and Africa in the Eocene appears to be much less supported than previously thought.

Proviverrine hyaenodontids (Creodonta: Mammalia) from the Eocene of Myanmar and a phylogenetic analysis of the proviverrines from the Para‐Tethys area

SYNOPSIS Recent expeditions in the Pondaung Formation have revealed an assemblage of hyaen‐odontid creodonts from the late middle Eocene of Myanmar. Among the three proviverrines known from the

Early African hyaenodontid mammals and their bearing on the origin of the Creodonta

The identification of Boualitomus and Tinerhodon as the most primitive and earliest known Hyaenodontidae, and the presence of cimolestids in the late Paleocene of Morocco, support an African origin of the family and its order.

The skeleton ofGazinocyon vulpeculusgen. et comb. nov. and the cladistic relationships of Hyaenodontidae (Eutheria, Mammalia)

Cladistic analysis suggests that Gazinocyon was related to a clade containing Eurotherium, Propterodon, Hyaenodon, and “Pterodon” hyaenoides, and suggests that Hyaeenodontinae (containing Pterodus, Hy...


Together, the eight carnivorous taxa now known from Moghra include not only some representatives of widespread genera common to localities across Eurasia and Africa, but also a number of unique faunal elements, including three new genera and five new species.

Craniodental Morphology and Systematics of a New Family of Hystricognathous Rodents (Gaudeamuridae) from the Late Eocene and Early Oligocene of Egypt

The oldest known remains of Gaudeamus are described, including largely complete but crushed crania and complete upper and lower dentitions, and Gaudeamurids are the only known crown hystricognaths from Afro-Arabia that are likely to be aligned with non-phiomorph members of that clade, and as such provide additional support for an Afro -Arabian origin of advanced stem and basal crown members of Hysticognathi.
