Opis:: The morphology of the single preserved molar of the holotype of the Australian Early Cretaceous (Aptian) mammal Teinolophos trusleri shows that it is a monotreme and probably a steropodontid, rather than a 'eupantothere' as originally proposed. The structure of the rear of the jaw of T. trusleri supports the molecular evidence that previously formed the sole basis for recognising the Steropodontidae as a distinct family.

Opis:: The phylogenetic relationships of the Paleocene crocodylian Akanthosuchus langstoni are assessed using published data matrices and morphological data from the holotype and referred specimens. Cladistic analyses indicate that Akanthosuchus is unequivocally nested within Alligatoroidea. Weak support from a majority rule consensus tree indicates that Akanthosuchus may be more closely allied with alligatorines than with caimanines, but in the strict consensus tree these relationships remain ambiguous. There is no evidence from phylogenetic analyses to support the hypothesis that Akanthosuchus represents the postcrania of the Paleocene crocodylians Navajosuchus or Ceratosuchus. Growth marks observed in histological sections of osteoderms of the holotype of Akanthosuchus langstoni indicate that it was at least eight years old at the time of death. Although the individual may not have been fully mature at the time of death, lineage dwarfism cannot be ruled out as a possible reason for its relatively small size.

Tytuł:: Potamogeton ×clandestinus (P. crispus × P. natans, Potamogetonaceae) : a new natural pondweed hybrid discovered in Europe
Autorzy:: Bobrov, Alexander A.
Chemeris, Elena V.
Zalewska-Gałosz, Joanna
Opis:: In this paper Potamogeton ×clandestinus (Potamogetonaceae), a hybrid between P. crispus and P. natans, is described and illustrated. Hybrid populations were discovered in the rivers Koloshma, Nozhema and Suda in the northern part of European Russia (Vologda reg., Babaevo distr.). Confirmation of the hybrid origin is based on morphological and anatomical data and independently was tested by a direct sequencing of the nuclear ribosomal ITS region and rpl32-trnL intergenic spacer of chloroplast DNA. The additive ITS sequence pattern confirmed that P. ×clandestinus is a hybrid between P. crispus and P. natans. The rpl32-trnL intergenic spacer data revealed that P. crispus was the maternal parent of the hybrid. A detailed morphological and ecological description of P. ×clandestinus is provided and the taxonomic differences between the new hybrid and similar taxa are outlined.

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:: A rich conodont fauna from two Neotethyan sections, Pizzo Mondello (western Sicily, Italy) and Pignola 2 sections (southern Apennines, Italy) includes conodonts described herein as a new species. Metapolygnathus praecommunisti sp. nov. is transitional between Paragondolella noah and Metapolygnathus communisti. The genus Metapolygnathus (including M. praecommunisti) is now characterised by posterior prolongation of the keel termination, associated with a centrally located pit and with a weak ornamentation confined to the anterior part of the platform margins. The establishment of M. praecommunisti addresses the problems related to the origin and the peculiar, probably facies−controlled, distribution of its descendant species M. communisti. Since M. praecommunisti occurs in the entire Tethys and in North America, we propose the species as a good guide fossil for global correlations, characterised by a short temporal range limited to the uppermost Tuvalian (upper Carnian). The stratigraphic occurrence of the genus Metapolygnathus is restricted to the Tuvalian–Lacian (upper Carnian–lower Norian), excluding its presence in the Julian substage (lower Carnian).

Opis:: The holotype of the brachyopoid temnospondyl Hadrokkosaurus bradyi, represented by a right lower jaw ramus, is re−examined based upon new data and revision of various morphological features. Additional fragmentary jaw material referred to this species is briefly described. Prominent features are a large postsymphyseal foramen that is anteriorly open, and prearticular and surangular buttresses for support of the articular. Brachyopoid characters include a long and robust postglenoid area formed by surangular and prearticular, anterior and posterior keels on at least some marginal dentary teeth, and subtriangular outline of the adductor fossa in dorsal view. Five features of the holotype ramus, long thought to be at odds with its brachyopoid or temnospondyl nature, are critically re−evaluated. A phylogenetic analysis of lower jaw characters in temnospondyls retrieves most of the clades found in more comprehensive data sets, but the statistical node support is low. Brachyopoids are monophyletic, with Hadrokkosaurus emerging as their most basal taxon.

Opis:: The Late Cretaceous South American sauropods Neuquensaurus australis and Saltasaurus loricatus are represented by well−preserved and abundant material that has been integral to our understanding of titanosaur anatomy for decades. Although the hypodigms for these species span most of the skeleton, holotypic materials are limited to a few bones that do not overlap between the two taxa. In this contribution, we augment the holotype of Neuquensaurus australis with a partial sacrum that was preserved in articulation with one of the caudal vertebrae from its original description, but not recognised as such at the time. We document this field association via the presence of a broken piece of matrix on the sixth sacral vertebral centrum that has a snap−fit to matrix on the rim of the anterior condyle of the holotypic biconvex vertebra. Based on comparisons with a more complete sacrum and ilium of a referred specimen of Neuquensaurus australis, we interpret this biconvex vertebra to be the seventh sacral vertebra. This raises the possibility that the biconvex “first caudal” vertebra of some other titanosaurs may be part of the sacrum as well. Augmentation of the Neuquensaurus australis holotype to include a sacrum makes it directly comparable to the holotype of Saltasaurus loricatus. Morphological differences in the number, shape, and proportion of sacral vertebrae allow discrimination between Neuquensaurus and Saltasaurus, confirming their generic separation. The El Brete quarry, which preserves the holotypic sacrum and abundant referred specimens of Saltasaurus loricatus, also preserves a sacrum consisting of seven vertebrae that bears autapomorphies of Neuquensaurus australis, indicating that these two saltasaurines coexisted.

Opis:: Chitracephalus dumonii was named based on some of the most complete turtle remains from the Lower Cretaceous of Europe, and yet the taxon has barely been mentioned since. Indeed, new specimens were erroneously attributed to a new taxon, “Salasemys pulcherrima”. The synonymy is recognized here, and this extends the geographical range of this turtle and provides examples of individuals at different stages of ontogenetic development. The peculiar structure of its shell, and its ontogenetic development, are unique to this taxon. The systematic position of C. dumonii was previously unclear, usually being referred to Testudinata incertae sedis. Here, it is placed in a cladistic analysis, which shows that C. dumonii, and the recently described Hoyasemys jimenezi form part of a Lower Cretaceous European clade of Cryptodira that includes “macrobaenid”, “sinemydid”, and panchelonioidean turtles.
