Opis:
Multituberculates were dominant mammals in the Late Cretaceous communities of Central Asia (present-day Mongolia), but very rare in the Late Cretaceous faunal assemblages from western Asia (Uzbekistan), where ungulate-like mammals dominated (Nessov et al. 1998). So far only one Late Cretaceous multituberculate taxon Uzbekbaatar kizylkumensis Kielan-Jaworowska & Nessov, 1992 was known from Uzbekistan. Here I describe the second Late Cretaceous multituberculate from the same area, Uzbekbaatar wardi sp. n., based upon an isolated p4 from the ?Santonian Aitym Formation at Dzharakuduk, Central Kyzylkum Desert, Uzbekistan. It differs from the Coniacian Uzbekbaatar kizylkumensis by somewhat derived morphology (larger size, greater number of p4 ridges and serrations).

Opis:
Until recently, the only mammal remains to be obtained from the Early Cretaceous (Barremian, Wealden Group) Wessex Formation of the Isle of Wight, southern England were a poorly preserved left m2 and a well preserved left I2 crown representing one or possibly two plagiaulacoid multituberculate species. These were recovered in the early 1970s but despite subsequent efforts by a number of workers to recover additional Mesozoic mammal remains none were forthcoming until comprehensive bulk screening of the Wessex Formation was undertaken in a study commenced in 2002. This study resulted in the recovery of a number of new specimens representing an assemblage of at least six taxa. Among these are a well−preserved plagiaulacoid multituberculate left m1 and a similarly preserved left I3. The former permits diagnosis of a new species of eobaatarid, Eobaatar clemensisp. nov. The previously recovered left m2 is also tentatively assigned to the same taxon. In addition, another left m1, somewhat worn as a result of dietary attrition, was recently obtained by a private collector. This is of very similar morphology to the holotype of E. clemensi but slightly larger. It is undoubtedly referable to the same taxon and provides some insight into intraspecific size, and other minor morphological variations in the teeth of the new species. The I3 may also be referable to the new species, in which case it is the first well preserved I3 of a member of Eobaataridae to be fully described.

Opis:
A dentary fragment containing a tiny left plagiaulacoid fourth lower premolar from the Early Cretaceous (Aptian) of Victoria provides the first evidence of the Multituberculata from Australia. This unique specimen represents a new genus and species, Corriebaatar marywaltersae, and is placed in a new family, Corriebaataridae. The Australian fossil, together with meagre records of multituberculates from South America, Africa, and Madagascar, reinforces the view that Multituberculata had a cosmopolitan distribution during the Mesozoic, with dispersal into eastern Gondwana probably occurring prior to enforcement of climatic barriers (indicated by marked differentiation in regional floras) in the Early Cretaceous.

Opis:
The Late Cretaceous multituberculate mammal Kryptobaatar dashzevegi Kielan−Jaworowska, 1970 is the most common mammalian taxon in the Upper Cretaceous (?lower Campanian) rocks of the Djadokhta Formation at Bayan Zag¹ (= Bayn Dzak) and Tögrög (= Toogreek), and in the beds of Ukhaa Tolgod in the Gobi Desert. Kryptobaataris also common in the Bayan Mandahu Formation (equivalent of the Djadokhta Formation), Inner Mongolia, China, represented there by K. mandahuensis. Kryptobaatar has not been reported as yet from the younger (?upper Campanian) Baruungoyot Formation nor from its stratigraphic equivalents, the red beds of Hermiin Tsav (= Khermeen Tsav). In this paper we report the discovery of an incomplete skull of Kryptobaatar dashzevegi at Hermiin Tsav I. It is the second mammal species common to the Djadokhta and Baruungoyot Formations (the first being Deltatheridium pretrituberculare). We provide a corrected list of mammals found in the Late Cretaceous localities of the Gobi Desert, and we argue (albeit inconclusively), that mammal evidence shows that the Ukhaa Tolgod beds might be closer in time of deposition to the Djadokhta Formation than to that of the Baruungoyot Formation.

Opis:
In this brief review I explain the method of quantitatively describing prismatic enamel microstructure in multituberculates, to facilitate its practical use by paleontologists. I argue that histogenesis of gigantoprismatic enamel in many multituberculate taxa must have been quite exceptional in mammals. Future studies of enamel in plesiomorphic “plagiaulacidan” multituberculates are necessary to elucidate the evolutionary phases of enamel micromorphology toward prismatic mammalian enamel generally, and perhaps as a consequence, the origin of the successful (Late Cretaceous–Eocene) multituberculate suborder Cimolodonta and relationships among its subgroups. Such studies should therefore include calculation of numerical prism densities whenever possible.

Opis:
The limb posture in early mammals is a matter of controversy. Kielan−Jaworowska and Gambaryan presented arguments for a sprawling posture in multituberculates, based mainly on three characters of the hind limbs (deep pelvis, mediolateral diameter of the tibia larger than the craniocaudal, and position of MtV, which fits the peroneal groove on the calcaneus and is not aligned with the axis of tuber calcanei). Here we present two more arguments for sprawling hind limbs in early mammals. One is the presence of an os calcaris, supporting the probably venomous spur in hind legs of docodontans, multituberculates, eutriconodontans, and “symmetrodontans”, similar to those of extant monotremes. We argue that early mammals (except for boreosphenidans) had sprawling limb posture and venomous spur; acquisition of the parasagittal stance was apparently characteristic only of boreosphenidans, in which the spur has not been found. The second argument is based on taphonomic evidence from lacustrine conditions (e.g., Early Cretaceous Jehol Biota), in which the mammalian skeletons, except for boreosphenidans (Sinodelphys and Eomaia), have been preserved compressed dorso−ventrally, suggesting sprawling stance. In similar conditions of the Eocene Messel Biota the skeletons of boreosphenidan mammals (except for bats and pangolins) are preserved lying on flanks, suggesting parasagittal stance. Sereno argued that forelimbs in multituberculates were parasagittal, based on the stated presence of a ventrally facing glenoid, a mobile shoulder joint, and an elbow joint with enhanced flexion−extension capability. However, these characters are not unequivocally indicative of parasagittalism. We demonstrate that the structure of the distal end of the multituberculate humerus is condylar, with no tendency for developing a trochlea. We reconstruct multituberculates and other early mammals with sprawling stance in resting position as plantigrade.

Opis:
Herein we describe the oldest well-sampled multituberculate assemblage from the Cretaceous of North America. The fauna is dated at 98.37 Ma and thus approximates the Albian-Cenomanian (Early-Late Cretaceous) boundary. The multituberculate fauna is diverse. Two of the multituberculates (Janumys erebos gen. et sp. n. and an unidentified taxon) are provisionally placed among 'Plagiaulacida'. Another taxon, Ameribaatar zofiae gen. et sp. n., is of uncertain subordinal affinities. The remaining multituberculates appear to represent the advanced suborder Cimolodonta and fall within the 'Paracimexomys group'. We rediagnose Paracimexomys on the basis of the type species, P. priscus, and refer to other species as cf. Paracimexomys (including cf. P. perplexus sp. n.). A revised diagnosis is also provided for Cenomanian Dakotamys. A previously-described species from the Cedar Mountain Formation is placed in Cedaromys gen. n. as C. bestia, together with C. pawus sp. n. Bryceomys is represented in the fauna by B. intermedius sp. n. Relationships of Paracimexomys-group to later taxa remain obscure. However, Bryceomys and Cedaromys share a number of features with Cimolodontidae. Given these resemblances, together with the fact that Cimolodontidae retain certain plesiomorphies (stout lower incisor, gigantoprismatic enamel) with respect to Ptilodontoidea (to which they are commonly referred), we suggest that Cimolodontidae may have arisen from a clade within the 'Paracimexomys group', independent of ptilodontoids.
W pracy opisano najstarszy dobrze opróbowany zespół zębów wieloguzkowców (Multituberculata) z kredy Ameryki Północnej. Fauna formacji Cedar Mountain jest datowana na 98,37 mln lat temu, a więc pochodzi mniej więcej z granicy albu i cenomanu (a więc przełomu wczesnej i późnej kredy). Fauna wieloguzkowców jest zróżnicowana. Dwa z nich (Janumys erebos gen. et sp. n. oraz nieoznaczony takson) tymczasowo zaliczono do ,,Plagiaulacida". Kolejny takson, Ameribaatar zofiae gen. et sp. n., ma niejasną przynależność na szczeblu podrzędu. Wydaje się, że pozostałe wieloguzkowce reprezentują, zaawansowany podrząd Cimolodonta i należałoby je umieścić w ,,grupie Paracimexomys". Diagnoza Paracimexomys została zrewidowana na podstawie gatunku typowego, P. priscus, toteż inne gatunki potraktowano jako cf. Paracimexomys (w tym cf. P. perplexus sp. n.). Zrewidowaną diagnozę uzyskał także cenomański Dakotamys. Opisany juz wcześniej z formacji Cedar Mountain gatunek umieszczony został w nowym rdozaju Cedaromys jako C. bestia, obok C. parvus sp. n. Bryceomys reprezentowany jest w opisywanej faunie przez B. intermedius sp. n. Niejasne pozostają pokrewieństwa między grupą Paracimexomys a późniejszymi taksonami. Bryceomys i Cedaromys mają jednak wiele cech wspólnych z rodziną Cimolodontidae. Ze względu na owe podobieństwa, a także na zachowanie przez Cimolodontidae pewnych plezjomorfii (masywny dolny siekacz, gigantopryzmatczne szkliwo) nieobecnych u Ptilodontoidea (do których się je zwykle zalicza), sugerujemy, ze Cimolodontidae mogły się wyodrębnić z kladu w obrębie ,,grupy Paracimexomys", niezależnie od ptilodontoidów.

The Gobi Desert is famous for providing one of the worlds best preserved Cretaceous terrestrial faunas, including dinosaurs and mammals. Beginning with the Central Asiatic Expeditions in the 1920s, through the Polish−Mongolian Expeditions in the 1960s–1970s, Soviet−Mongolian Expeditions in 1970s, and finally the Mongolian Academy−American Museum Expeditions in the 1990s–2000s, the number of complete skulls (see Kielan−Jaworowska et al. 2000 for review) of Cretaceous mammals often associated with postcranial skeletons, found in Mongolia increased to several hundred. In addition to these professional expeditions, there have been other types of trips to Mongolia, also aimed at collecting fossils. The Nomadic Expeditions Company in USA organizes one of these, and has made trips to Mongolia since 1996. During the 1999 Nomadic Expedition, a skull associated with parts of the postcranial skeleton of the multituberculate mammal Catopsbaatar catopsaloides was found. The specimen is more complete than others previously known of this species and brings new data on multituberculate anatomy and ontogenetic variation. In this note we discuss the new data on the structure of C. catopsaloides; the details of its anatomy will be described in subsequent papers by the two first authors.

Three new multituberculate teeth are described from the Early Cretaceous of Morocco. Denisodon moroccensis gen. et sp. nov. is established for a second lower molar which differs from that of Hahnodon taqueti, from the same locality, by a preserved posterior buccal cusp, a smaller posterior lingual cusp and the less indented lingual wall of the crown. The second tooth is a posterior upper premolar. It is represented by the posterior portion of its crown on which is present only one row of cusps, similar to the conditions in Kielanodon, Eobaatar, Bolodon, and the Pinheirodontidae. The third tooth is a lower incisor, similar to that in Kuehneodon. Both teeth are grouped as „Hahnodontidae, gen. et sp. indet.” Paulchoffatioidea new superfamily is established for the Paulchoffatiidae, Hahnodontidae, and Pinheirodontidae. It is characterized by the following autapomorphies: premolarisation of I2−C, presence of a third row of cusps on the posterior upper premolars and the basin−like structure of the m2. Hahnodontidae and Hahnodon are redefined.

Opis:
Multituberculates are the most diverse and best known group of Mesozoic mammals; they also persisted into the Paleogene and became extinct in the Eocene, possibly outcompeted by rodents that have similar morphological and presumably ecological adaptations. Among the Paleogene multituberculates, those that have the largest body sizes belong to taeniolabidoids, which contain several derived species from North America and Asia and some species with uncertain taxonomic positions. Of the known taeniolabidoids, the poorest known taxon is Sphenopsalis nobilis from Mongolia and Inner Mongolia, China, represented previously by a few isolated teeth. Its relationship with other multituberculates thus has remained unclear. Here we report new specimens of Sphenopsalis nobilis collected from the upper Paleocene of the Erlian Basin, Inner Mongolia, China, during a multi-year field effort beginning in 2000. These new specimens document substantial parts of the dental, partial cranial and postcranial morphologies of Sphenopsalis, including the upper and lower incisors, partial premolars, complete upper and lower molars, a partial rostrum, fragments of the skull roof, middle ear cavity, a partial scapula, and partial limb bones. With the new specimens we are able to present a detailed description of Sphenopsalis, comparisons among relevant taeniolabidoids, and brief phylogenetic analyses based on a dataset consisting of 43 taxa and 102 characters. In light of the new evidence, we assess the phylogenetic position of Sphenopsalis and re-establish the family Lambdopsalidae. The monophyly of Taeniolabidoidea is supported in all our phylogenetic analyses. Within Taeniolabidoidea the Asian lambdopsalids and the North American taeniolabidids represent two significantly different trends of adaptations, one characterized by shearing (lambdopsalids) and the other by crushing and grinding (taeniolabidids) in mastication, which supports their wider systematic separation, as speculated when Sphenopsalis was named.

Uzbekbaatar Kielan−Jaworowska and Nessov, 1992 is among the rarest mammals and the only multituberculate in the diverse, eutherian dominated Bissekty (Turonian) and Aitym (?Coniacian) local faunas, Kyzylkum Desert, Uzbekistan. New material from the Bissekty local fauna, suggests that only one multituberculate species, Uzbekbaatar kizylkumensis Kielan−Jaworowska and Nessov, 1992 is present in the Bissekty fauna. A newly collected p4 is better preserved than the holotype and demonstrates presence of the posterolabial cusp in the p4 of Uzbekbaatar. New material of Uzbekbaatar is consistent with placement of this taxon within the basal cimolodontan “Paracimexomys group.”
