Les mammifères Montiens de Hainin (Paléocène moyen de Belgique) Part II : Les Condylarthres
Jean Sudre and Donald E. Russell
Keywords: Belgium; Condylarths; Louisininae; Oxyclaeninae; Paleocene
 
  Abstract

    The Condylarths from Hainin (Hainault, Belgium) show no affinity at the generic level to those known in other Paleocene localities of Europe and North America ; they are described as new forms : Monshyus praevius n. gen., n. sp. and Prolatidens waudruae n. gen., n. sp. Monshyus praevius, discovered in only one of the levels in the excavation at Hainin, is similar to the genera Microhyus TEILHARD and Louisina RUSSELL ; with them it is included in the subfamily Louisininae (Hyopsodontidae). With respect to Microhyus and Louisina, Monshyus is distinguished by the precociously modern aspect of its upper molars, the only teeth that are referable. Prolatidens waudruae, known only by lower molars, was found in several levels in the pit at Hainin. It is an arctocyonid presenting possible relationships to the North American form Oxyprimus galadrielae ; it therefore has been provisionally attributed to the subfamily Oxyclaeninae. If this attribution is confirmed, this species will constitute the first and only representative of the group in Europe.

Sur les Condylarthres Cernaysiens Tricuspiodon et Landenodon (Paléocène supérieur de France)
Donald E. Russell
Keywords: Arctocyonidae; Condylarths; Late Paleocene; Tricuspiodontidae
 
  Abstract

    The numerical importance of the Condylarths in the Cernaysian fauna is discussed. The Condylarth family, Tricuspiodontidae, is reviewed in the light of new material and its close relationships to the Phenacodontidae is suggested ; one new species is recognized : Tricuspiodon sobrinus. European Arctocyonidae are reviewed and the recentclassification of Van Valen is briefly commented on. Also,  the arctocyonine Landenodon is described for the first time in Thanetian (Late Paleocene) sediments ; two new species are proposed : T. lavocati and T. phelizoni

La variabilité morphologique dentaire du Landenodon (Condylarthra) de Dormaal, (Eocène,Belgique)
Marc Godinot
Keywords: Condylarths; Dormaal; Early Eocene; Landenodon
 
  Abstract

    The study of dental variations in Landenodon from Dormaal (early Eocene, Belgium) shows that only one
    species is present in this locality : L. woutersi QUINET, 1968 (Condylarthra, Arctocyonidae, Arctocyoninae). A high morphological variability is described, especially concerning the metaconid of P/4, the paraconid of M/2, and some characters of M1/ which have been found to be independant of each other. This variability is discussed.
