A recently (Krause 2001) reported fragmentary mammalian lower molar (University of Antananarivo, UA 8699) from the Late Cretaceous (Maastrichtian) of Madagascar, was attributed to Marsupialia, for which far reaching paleobiogeographical conclusions were made. The five characters used to identify UA 8699 as a marsupial are not exclusive to Late Cretaceous marsupials, but are found also in some placental mammals, notably in Late Cretaceous ungulatomorph zhelestids, known from various Upper Cretaceous strata in Asia, Europe, and NorthAmerica (Nessov et al. 1998). Identification of UA 8699 as a zhelestid placental is in keeping withmyriad other faunal similarities between Europe and Africa/Madagascar.

The morphology of the first lower molar (M1) of Microtus (Terricola) multiplex (Fatio, 1905) was compared amongst 15 populations from the Alps (Switzerland, Italy, France). M. multiplex orientalis from Trentino Alto Adige is close to the nominative subspecies M. multiplex multiplex from Ticino characterised by a great size, a not tilted pitymyan rhombus and an important development of the anterior part of the M1. M. multiplex druentius from Ubaye mainly differs from the nominative subspecies by a smaller tooth size. Populations from Valle d’Aosta and Piemonte show on the whole a morphology intermediate between M. m. multiplex and M. m. druentius subspecies, however, the pitymyan rhombus is more tilted and the development of the anterior part more reduced in populations from Eastern and Central Piemonte. The Western populations (from Trièvès, Vercors, Royans and Chambaran) belonging to the subspecies M. m. niethammeri are the most differentiated with a small or median size of the M1, a reduced development of the anterior part and a very tilted pitymyan rhombus, particularly in the population from Chambaran. The populations from Matheysine and Grésivaudan are morphologically a link between M. m. druentius and M. m. niethammeri subspecies.

The Middle Jurassic mammal Shuotherium has lower molars that possess a trigonid and talonid, but are unique in having the talonid situated in front of the trigonid, rather than behind it, as in molars of usual tribosphenic pattern. Shuotherium dongi Chow and Rich, 1982 was based on a dentary bearing seven teeth, originally interpreted as three premolars and four molars. Based on comparison with other groups of early mammals, we reinterpret the premolar–molar boundary in the holotype of S. dongi, and propose a dental formula of four (or more) premolars and three molars. The ultimate lower premolar (previously identified as the first molar) has a completely developed trigonid and no talonid or pseudo−talonid. We hypothesize that the mesial cingulid on molars of Australosphenida is a highly plausible structural antecedent to the pseudo−talonid of Shuotherium. This and other shared, derived features support a relationship of Shuotherium and Australosphenida as sister−taxa. We hypothesize that the common ancestor of Shuotherium + Australosphenida had a global distribution no younger than early Middle Jurassic, and that the respective clades diverged prior to full separation of Gondwanan and Laurasian landmasses.

The M,-morphology of seven isolated populations of voles displaying a pitymyan rhombus from the Eastern Alps (including the probably extinct Microtus bavaricus) was compared with that of M. multiplex, M. liechtensteini, and M. tatricus as well as among each other, by using discriminant and canonical discriminant analyses. The genera! morphometry of the M, and the analysis of the Mj parameters show these populations to be related to M. liechtensteini and multiplex, more closely to liechtensteini but not in complete accordance with comparative liechtensteini-material from Slovenia and Croatia. The seven samples show a remarkable variation between each other that cannot be associated with their respective geographic provenance. They can be classified into three groups, one consisting of M. bavaricus only, one of true liechtensteini (Carinlhia and Eastern Tyrol) and a third represented by a sample of the upper Enns valley in Styria, characterized by a very aberrant M, morphology.

A dentary fragment containing the last two molars (m2–3) from the Late Cretaceous (Santonian–?Campanian) Bostobe Formation exposed at the locality of Shakh Shakh, northeast Aral Sea region, Kazakhstan, is attributed to a new taxon of Zhelestidae, Zhalmouzia bazhanovi Averianov and Archibald gen. et sp. nov. This specimen is only the second mammal described from Shakh Shakh, the unidentifiable eutherian Beleutinus orlovi Bazhanov, 1972, being the first, and it is only the fifth Mesozoic mammal named from Kazakhstan. Zhalmouzia Averianov and Archibald gen. nov. belongs to the endemic clade of Middle Asian zhelestids (Zhelestinae), better known from the Turonian of Uzbekistan.

We studied phenotypic relationships among 13 samples of two rock mice species:Apodemus mystacinus (Danford and Alston, 1877) from Anatolia (n = 38) andA. epimelas (Nehring, 1902) from the Balkans (n = 71). Cartesian coordinates of landmarks were collected on the skull and on the occlusal projection of the upper molars (18 landmarks). Centroid size (a measure of overall size) suggested that molars vary independently of overall skull size in both species. Discriminant function analysis on relative warp scores classified >80% of specimens into the correct species, with the best results obtained for the ventral aspect of the skull and for molars. Projection of the 1st discriminant function scores against centroid size provided good separation between the two species. Analysis of vector displacements associated with extremes of variation suggested considerable phenetic differences on the ventral side of the skull and in the molar shape of the two species. The great majority of shifts in landmarks were in a longitudinal direction and the rearrangements of molar cusps were more complex than was the case with the cranium. A bivariate plot of the posterior hard palate length against the incisive foramen length separatedA. mystacinus andA. epimelas well.

We describe an additional fragmentary upper molar and the first lower molar known of Monotrematum sudamericanum, the oldest Cenozoic (Paleocene) monotreme. Comparisons suggest that the monotreme evolution passed through a stage in which their molars were “pseudo−triangulate”, without a true trigonid, and that the monotreme pseudo−triangulate pattern did not arise through rotation of the primary molar cusps. Monotreme lower molars lack a talonid, and consequently there is no basin with facets produced by the wearing action of a “protocone”; a cristid obliqua connecting the “talonid“ to the “trigonid” is also absent. We hypothesize that acquisition of the molar pattern seen in Steropodon galmani (Early Cretaceous, Albian) followed a process similar to that already postulated for docodonts (Docodon in Laurasia, Reigitherium in the South American sector of Gondwana) and, probably, in the gondwanathere Ferugliotherium.

Linear furrows have been documented in the crown cement of Mammuthus primigenius molars from the late Pleistocene archaeological sites of Kraków Spadzista Street (B), Poland and Vogelherd, Germany. The high frequency of cement defects on these assemblages, 50% and 74% of the molars respectively, and on other fossil proboscidean teeth from Eurasia warrants investigation into their etiology. One possible cause of the furrows is a developmental defect such as hypoplasia, due to periodic physiological stress; such a causal factor could have broad implications for the life history of woolly mammoths. Other potential origins of the furrows include cement decay from infection or impaction of material in the gums and resorption of tooth cement. Apart from cause, the morphology of the cement furrows reflects regular rhythms of seasonal or annual formation.

Comparison of the early allotherian genera, Haramiyavia, Thomasia, Theroteinus, and Eleutherodon shows that their molariform teeth are variants of a common pattern, justifying the inclusion of these genera in a single order Haramiyida. Haramiyavia is made the type of a new family Haramiyaviidae. The order Haramiyida is divided into two suborders: (1) Theroteinida (only family Theroteinidae), and (2) Haramiyoidea (families Haramiyaviidae, Haramiyidae, Eleutherodontidae). Dental resemblances support the hypothesis that the Multituberculata originated within the Haramiyida, in which case the Haramiyida would be paraphyletic. Derivation of multituberculates from within the Mammaliaformes would involve a highly improbable transformation of the dentition. It is therefore postulated that allotherian (Haramiyida + Multituberculata) and non-allotherian mammaliaform clades separated before the Mammaliaformes developed a shearing dentition with unilateral occlusion and transverse jaw movements. This hypothesis implies that the two clades evolved to a large extent in parallel, to account for the apparent synapomorphies of multituberculates and therians.
