A New Gobiconodontid Mammal from the Early Cretaceous of Spain and Its Palaeogeographic Implications
A new gobiconodontid mammal from the Early Cretaceous of Spain and its palaeogeographic implications Gloria Cuenca-Bescós and José I. Canudo Acta Palaeontologica Polonica 48 (4), 2003: 575-582 A new gobiconodontid from Vallipón (Teruel, Spain) represents the first record of this family in Europe. The site has a diverse fossil assemblage mainly composed of isolated bones and teeth probably accumulated by tidal action and water streams in an ancient beach of upper Barremian, in the transitional marine-continental sediments of the Artoles Formation. The new gobiconodontid consist of an isolated upper molar, smaller in size than that element in other gobiconodontids, with a robust cusp A, characterised by lateral bulges on each mesial and distal flanges of that cusp, and a discontinuous cingulum raised at the lingual side. The oclusal outline is smooth compared with Gobiconodon borissiaki, Gobiconodon hoburensis, or Gobiconodon ostromi. The Gobiconodontidae record is exclusively Laurasiatic. The oldest gobiconodontid fossil remains are Hauterivian; though their probable origin has to be found at the Late Jurassic in Central Asia (as inferred from derived character of the first gobiconodontids as well as phylogenetic relationships). At the end of the Early Cretaceous they expanded throughout Laurasia as indicated by findings in Asia, North America and Spain. Two dispersion events spread gobiconodontids: to the West (Europe) in the Barremian and to the East (North America) during the Aptian/Albian. Key words: Cretaceous, Barremian, Mammalia, Gobiconodontidae, Europe, palaeogeography.

Mammalian Faunal Succession in the Cretaceous of the Kyzylkum Desert
Journal of Mammalian Evolution, Vol. 12, Nos. 1/2,C 2005)June 2005 ( DOI: 10.1007/s10914-005-4867-3 A number of typographical errors were introduced during copyediting. All that were found were corrected in this version. Mammalian Faunal Succession in the Cretaceous of the Kyzylkum Desert J. David Archibald1,3 and Alexander O. Averian2 ov Both metatherians and eutherians are known from the Early Cretaceous (Barremian, 125 mya; million years ago) of China, while eutherian-dominated mammalian faunas appeared in Asia at least by the earliest Late Cretaceous (Cenomanian, 95 mya). The approximately 99–93 my old (Cenomanian) Sheikhdzheili l.f. from western Uzbekistan is a small sample of only eutherians, including three zhelestids and a possible zalambdalestoid. The much better-known 90 my old (Turonian) Bissekty l.f. at Dzharakuduk iin central Uzbekistan includes 15 named and un- named species, based on ongoing analyses. Of these, 12 are eutherians represented by at least the three groups—asioryctitheres, zalambdalestids, and zhelestids—plus an eutherian of uncertain position—Paranyctoides. Zalambdalestids and zhelestids have been argued to be related to the origin of the placental gliriforms (Euarchontoglires) and ferungulates (Laurasiatheria), respec- tively. Although there are four previously recognized metatherians, we believe three are referable to the deltatheroid Sulestes karakshi and the fourth, Sailestes quadrans, may belong to Paranyc- toides. There is one multituberculate and one symmetrodont in the Bissekty l.f. While comparably aged (Turonian) localities in North America have somewhat similar non-therians, they have more metatherians and no eutherians. The next younger localities (early Campanian, ∼80 mya) in North America have both a zhelestid and Paranyctoides, suggesting dispersal of eutherians from Asia. -

Aptian–Albian) of Texas and Oklahoma
Reappraisal of the tribosphenidan mammals from the Trinity Group (Aptian–Albian) of Texas and Oklahoma BRIAN M. DAVIS and RICHARD L. CIFELLI Davis, B.M. and Cifelli, R.L. 2011. Reappraisal of the tribosphenidan mammals from the Trinity Group (Aptian–Albian) of Texas and Oklahoma. Acta Palaeontologica Polonica 56 (3): 441–462. The Trinity therians have long been the focus of attempts to reconstruct the evolutionary history of higher mammals, es− pecially in the context of the development of tribospheny. In this paper, we update the taxonomy of the tribosphenidan taxa known from the Trinity Group and establish with more confidence the premolar/molar count in each. Many isolated specimens can be referred to a specific tooth locus. Additional diversity is revealed within the Deltatheroida, with the de− scription of an additional species of Oklatheridium; Pappotherium is here considered a likely metatherian based on the in− ferred presence of four molars, while Holoclemensia is a basal eutherian (the opposite of some traditional interpretations). The remainder of the genera, Kermackia and Slaughteria, cannot be allied with either of the living groups of tribo− sphenidan mammals using the available data. We identify strong morphological diversity within this assemblage of stem taxa, including modifications to the traditional tribosphenic occlusal pattern in Kermackia. Mammalian evolution at the base of the tribosphenidan radiation was complex, and this underscores the need for caution when interpreting the mor− phology and relationships of taxa known by incomplete material. Key words: Tribosphenida, Metatheria, Eutheria, Deltatheroida, Trinity Group, Early Cretaceous. Brian M. Davis [[email protected]] and Richard L.
