Rates of evolution in divergent species lineages as a test of character displacement in the fossil record : tooth size in Paleocene Plesiadapis (Mammalia, Proprimates)Phillip D. GingerichKeywords: character displacement; character divergence; fractal time series; Plesiadapis; Rates of evolutionAbstract Two species lineages of North American late Paleocene Plesiadapis exhibit a pattern of size divergence from a common ancestral lineage. Time series of fossils in each of these lineages are analyzed to test the idea that size divergence represents competitive character displacement. The critical factor in a test of character divergence is showing that divergent lineages evolved directionally rather than randomly (multifactorially). Analysis of evolutionary rates and their temporal scaling in Plesiadapis shows that both divergent species lineages have the scaling slope expected for lineages evolving randomly rather than directionally, and size divergence in Plesíadapis does not represent character displacement. Rates of evolution commonly observed on a per-generation time scale are high enough to produce character displacement within a few generations. Thus character displacement is not likely to be visible on scales of time that can be studied in the fossil record. Article infos Published in Vol. 25, Fasc. 2-4 (1996) |

Découverte d'un gisement de micromammifères d'âge Pliocène dans le bassin de Constantine (Algérie), présence d'un muridé nouveau : Paraethomys Athmeniae n.sp.Brigitte Coiffait and Philippe-Emmanuel CoiffaitKeywords: Algeria; Constantine; Micromammals; Muridae; PlioceneAbstract The study of that locality allowed the description of a new Muridae : Paraethomys athmeniae n. sp. It reveals the existence of new rodent for Algeria : first, a Sciuridae, Atlantoxerus cf. rhodius, and second, a Gliridae, Eliomys truci. So, that work shows the presence of the genus Eliomys in North Africa before the middle of Pleistocene. Lastly, Paraethomys cf. anomalus gives an exact datation of that bed.

La poche à phosphate de Ste-Néboule (Lot) et sa faune de vertébres du Ludien supérieur. 4- CrocodiliensEric BuffetautKeywords: Eocene; Quercy PhosphoritesAbstract Crocodilians are represented in the Upper Eocene of Sainte·Néboule (Lot) by an isolated parietal and a dorsal scute, bath from young individuals. They are refferred to Diplocynodon sp. Predators (mammals and birds) are probably responsible for the occurrence of remains of small crocodilians (belonging to the genera Allognathosuchus and Diplocynodon) in the phosphorltes of Quercy.

Un gisement à mammifères dans la formation lacustre d'âge Miocène moyen du Collet Redon près de St-Cannat (Bouches-du-Rhone). Implications stratigaphiquesJean-Pierre Aguilar and G. ClauzonKeywords: France; Neogene; RodentiaAbstract The new fauna of Collet Redon (Bouches-du-Rhône, France) is dated by three rodents: Megacricetodon aff. bavaricus, Democricetodon affinis mutilus and Peridyromys cf. hamadryas. They correlate this locality with Oggenhof and Ohningen in Bavaria (Western Germany). As the radiometric age of Ohningen is estimated between 14 and 13 M.Y., these three localities are of Serravallian age. This datation brings a complete readjusment of the stratigraphy of the section of Collet Redon formerly described by Collot and Combaluzier. The marine deposits with underly the continental formation with the mammal fauna, are Burdigalian. The angular unconformity between the marine and the continental deposits gives evidence of an episode of emersion on the margin of a sedimentary basin, with deformation and erosion. Owing to the newly discovered fauna, this geodynamical event is clearly settled within the regional geographical and chronological context. Lacustrine and continental deposits of such an age were up to now unsuspected in this area. Article infos Published in Vol. 08, Fasc. 5 (1979) |

Sur la présence de dents de mammifères (Creodonta, Perissodactyla) près de la limite Paléocène-Eocène à Hoegaarden, BelgiqueRichard Smith and Jerry J. HookerKeywords: Belgium; Creodonta; Landenian; Mammals; PerissodactylaAbstract Amongst a collection of selachian teeth made at Hoegaarden in a marine level of Bruxellian (Lutetian) age, containing a reworked Landenian (Sparnacian) fauna mixed with a contemporaneous one, a few teeth of terrestrial mammals have been discovered. They comprise two rare European taxa: ? Hallensia sp. and Palaeonictis gigantea, both known from the Landenian. Even though the ?Hallensia has not been definitely identified, il differs from the only perissodactyl of this age previously recorded from Belgium (Cymbalophus cuniculus).

Origins of avian reproduction: answers and questionsfrom dinosaurs.David J. Varricchio and Frankie D. JacksonKeywords: Avian reproduction; clutch; dinosaurs; egg size; nests; oviducts; parental careAbstract The reproductive biology of living birds differs dramatically from that of other extant vertebrates. Distinctive features common to most birds include a single ovary and oviduct, production of one egg at daily or greater intervals, incubation by brooding and extensive parental care. The prevalence of male parental care is most exceptional among living amniotes. A variety of hypotheses exist to explain the origin of avian reproduction. Central to these models are proposed transitions from a condition of no care to maternal, paternal or biparental care systems. These evolutionary models incorporate a number of features potentially preservable or inferable from the fossil record (integument, skeletal adaptations for flight, egg and clutch size, nest form, hatchling developmental stage, the number and function of oviducts, and the mode of egg incubation). Increasing availability of data on dinosaur reproduction provides a means of assessing these hypotheses with fossil evidence. We compare dinosaur data to a selection of models that emphasize maternal, paternal or biparental care. Despite some congruence with dinosaur features, no single model on the evolution of avian reproduction conforms fully to the fossil record, and the ancestral parental care system of birds remains ambiguous. Further investigation into dinosaur parental care, nest structures, clutch geometry, egg-pairing, eggshell porosity, and embryo identification may eventually resolve these issues.

Nouvelle interprétation de l'évolution du genre Megacricetodon au cours du MiocèneJean-Pierre AguilarKeywords: Megacricetodon; Micromammals; MioceneAbstract La découverte de nouveaux gisements à micromammifères dans le Miocène du Sud de la France et d'Espagne montre que, s'il n'est plus possible d'accepter dans son intégralité le schéma phylétique de Fahlbusch du genre Megacricetodon, il existe toutefois des segments de lignées à l'intérieur de provinces géographiques différentes (Péninsule Ibérique, France, Europe Centrale), avec lesquels on peut établir une biochronologie locale, segments qu'il est aussi possible de placer les uns par rapport aux autres, en utilisant les corrélations que l'on peut reconnaître entre certains niveaux repères des mammalogistes et l'échelle stratigraphique marine.

Designating a lectotype for Mesacanthus pusillus (Gnathostomata: Acanthodii)Matthew Baron and Kevin SeymourKeywords: acanthodians; Chordata; Devonian; Midland Valley; Orcadian Basindoi: 10.18563/pv.44.1.e2 Abstract The early gnathostome genus Mesacanthus is well represented in both Lower Old Red Sandstone and Middle Old Red Sandstone assemblages of northern and central Scotland. This ‘acanthodian’ taxon is currently thought to comprise two valid species: M. mitchelli and M. pusillus. Although the whereabouts of the holotype of M. mitchelli (NHMUK PV P560) is known, the syntype material for M. pusillus has long been thought lost. Here we identify at least one specimen that formed part of the original syntype material for M. pusillus, albeit in a slightly different condition than when it was originally figured. This specimen is ROM 25872, which is here designated as the lectotype. A second specimen – ELGNM 1978.191.1 – could represent another of the syntype specimens, but poor preservation quality makes it impossible to be certain. Article infos Published in 44-1 (2021) |

A new vertebrate locality in the eifelian of the khush-yeilagh formation, Eastern Alborz, IranAlain Blieck, Farrokh Golshani, Daniel Goujet, Amir Hamdi, Philippe Janvier, Elga Mark-Kurik and Michel MartinKeywords: Devonian; Iran; khush-yeilagh formation; VertebrateAbstract A new Devonian vertebrste locality has been discovered in 1976 in the basal part of the Khush-Yeilagh Formation in the eastern Alborz Mountains of Iran. The fossils occur in a band one centimeter thick which is identifiable at other outcrops in the area. A preliminary study of the remains has yielded the following faunal list : Placodermata (Phlyctaeniida indet.. Groenlandaspididae indet.. Coccosteidae indet., Holonema sp., Ptyctodontida indet., Antiarcha indet., Bothriolepis cf. kwangtungensis), Elasmobranchii (Ctenacanthidae indet.), Acanthodii (Gyracanthus sp., « Onchus » overathensis, Ischnacanthiforme indet.), Dipnoi (? Dipteridae indet.), « Crossopterygii ›› (Onychodus cf. sigmoides, Holoptychiidae indet., Osteolepididae indet.). This fauna is older than the Middle Givetian and probably of Middle or Lower Eifelian age. Owing to its diversity, it may prove possible to use it in the future as a reference fauna for the study of the Devonian vertebrates in Central Asia and the Middle East.

Cricetid and arvicolid rodents of the California wash local fauna, late Blancan of the san Pedro Valley, Arizona.Cristiana MezzabottaKeywords: Arvicolidae; Blancan; Cenozoic; Cricetidae; MammalsAbstract An assemblage of micromammals is reported from California Wash, a fossil bearing continental deposit in the San Pedro Valley, Arizona, late Blancan in age. Cricetid and Arvicolid rodents are richly represented, including four and two species, respectively. This study mainly focuses on Sígmodon, the most abundant form. The sample of Sigmodon is compared to samples of the same genus from other localities of the San Pedro Valley of comparable age, and some inferences on the taxonomy of the genus are attempted. The specimens are referred to Sigmodon minor and Sigmodon cf. S. curtisi. Other cricetids (Onychomys pedroensis and Baiomys brachygnathus) and arvicolids (Mictomys vetus and Ondatra ídahoensis) are also recognized and described.

Rongeurs du Miocène supérieur de Chorora (Ethiopie): Cricetidae, Rhizomyidae,Phiomyidae, Thryonomyidae,Sciuridae.Denis GeraadsKeywords: cricetids; Ethiopia; phiomyids; rhizomyids; Rodentia; sciurids; thryonomyids; Upper MioceneAbstract Besides Dendromurids and Murids, the Chorora Rodents include 7 taxa, two of which are new. Afaromys nov. gen. is a Cricetodontine with very complicated lower molars, certainly isolated for a long time from Eurasian species. A Paraphiomys, with tetralophodont upper molars, is also quite different from other East African species, and its roots should probably he searched in the middle Miocene. Other taxa are less original, and more similar to the South Asiatic ones. Article infos Published in Vol. 27, Fasc. 3-4 (1998) |

The application of this method of study to the molars of European Tertiary Didelphidae shows that the lineage of this family as represented by the species Peratherium cuvieri (Upper Eocene), P. elegans (Lower-middle Oligocene) and P. antiquum (Upper Oligocene) has propessively evolved toward a more carnivorous diet.
