High‐level phylogeny of early Tertiary rodents: dental evidence
A cladistic assessment of the dental evidence for early Tertiary rodent cladogenesis provides evidence of a fundamental dichotomy in early rodent history, including the pentalophodonty of molars, zygomasseteric complex and incisor enamel microstructure.
Study of the diet effect on δ13C of shell carbonate of the land snail Helix aspersa in experimental conditions
Abstract This study aims to demonstrate the influence of the metabolic CO2 derived from the diet and of the atmospheric CO2 on the shell carbonate δ13C of the pulmonate snail Helix aspersa maxima
Late Cretaceous dinosaur eggshells from the Tremp Basin, southern Pyrenees, Lleida, Spain
Late Cretaceous dinosaur eggshell assemblages from six localities of the Tremp basin (Southern Pyrenees, Lleida, Spain) are studied and compared with those of Southern France, to correlate their
The role of Asia in the origin and diversification of hystricognathous rodents
A cladistic assessment of the dental evidence for the Palaeogene hystricognathous rodent cladogenesis indicates that ‘baluchimyines’ and tsaganomyids are representatives of an initial phase of diversification of hystricsened rodents in Asia, which clearly points to an Asian origin for HyStricognathi.
Comparisons between nine oospecies from India and France reveal similarities in egg taxa which suggest close phyletic relationships, as well as the probable existence of a terrestrial connection of dinosaur fauna between India and Europe during the Cretaceous, and between the two gondwanan areas Patagonia and India.
Zegdoumyidae (Rodentia, Mammalia), stem anomaluroid rodents from the Early to Middle Eocene of Algeria (Gour Lazib, Western Sahara): new dental evidence
The Palaeogene fossil record of rodents in Africa is very poor compared to that of North America or Eurasia. Despite this, Africa has long appeared to be a centre of adaptive radiation for two
Cranial Remain from Tunisia Provides New Clues for the Origin and Evolution of Sirenia (Mammalia, Afrotheria) in Africa
X-ray microtomography is used to investigate a newly discovered sirenian petrosal from the Eocene of Tunisia, which represents the oldest occurrence of sirenians in Africa and supports their African origin.
Dinosaur eggshells as biochronological markers in Upper Cretaceous continental deposits
Abstract European dinosaur eggshells are now well organized in a parataxonomic classification and can be used as reliable biochronological markers for Upper Cretaceous continental deposits. The
A new mammalian fauna from the earliest Eocene (Ilerdian) of the Corbières (Southern France): palaeobiogeographical implications
A new mammal fauna from the earliest Eocene of Le Clot (Corbières, Southern France) is described. Some taxa identified there, such as Corbarimys hottingeri and Paschatherium plaziati, allow a
The Cricetidae (Rodentia, Mammalia) from the Ulantatal area (Inner Mongolia, China): New data concerning the evolution of Asian cricetids during the Oligocene
The Cricetidae from Ulantatal provide evidence suggesting faunal exchanges between Asia and Europe through the Paratethyan pathway during the second half of the Paleogene, and reinforce the assumed early diversification of cricetids in this part of Asia.
