On ornithischian phylogeny

tom 30

nr 3-4
The ornithischian dinosaurs are analysed using the cladistic methodology. The preferred hypothesis (see fig. 1) is that: 1. Ornithischia are monophyletic, 2. Ankylosauria are sister group of all other ornithischians, 3. Pachycephalosauria + Ceratopsia are monophyletic unit sharing common characters not found in other ornithischians. Quadrupedality is considered as primitive ornithischian condition.

The quadrate of oviraptorid dinosaurs is strongly pneumatized and differs from the quadrates of other non-avian theropods by: (1) two separate facets on the otic process for contacts with the squamosal and braincase; (2) the articular surface for the pterygoid extended to the articular surface of the medial mandibular condyle; (3) the mandibular process provided laterally with a quadratojugal process bearing the quadratojugal cotyla. In the above characters the oviraptorid quadrate resembles those in most ornithothoracine birds, but, contrary to the streptostylic quadrate of birds, the oviraptorid quadrate is monimostylic.

Some implications of hadrosaurian postcranial anatomy

nr 1-2
All articulated hadrosaurian skeletons expose a comparatively abrupt ventral flexure of anterior thoracal portion of the vertebral column. This resulted in effective shortening of the body anterior to the acetabulum and in shifting backward the gravity center of the heavy thoracal part, in deepening of pleural cavity as well as in lowering the suspension point of the fore limb at the glenoid, making easier access of the fore limb to the ground. In some hadrosaurs at least, sacropelvic contact was strengthened by a forward extension of the acetabular bar, so that pubis also was keyed to sacrum by a sacral rib, and the puboiliac contact was reinforced. This enabled these hadrosaurs to assume and sustain a stance with the vertebral column inclined upwards.

A microvertebrate assemblage from the Early Triassic of Poland

The Early Triassic microvertebrate assemblage from karst deposits of Czatkowice quarry, Kraków Upland, Poland, has been dated as of latest Olenekian age at youngest. The assemblage contains mainly small reptiles: three to four possible genera of procolophonids, a small predatory archosaur of proterosuchid or pre-proterosuchid grade, a prolacertiform, and one or two genera attributable to Lepidosauromorpha, one of them, very small, being a possible stem-lepidosaurian. Furthermore there are some less numerous amphibians, including the first European salientian (stem-frog) - Czatkobatrachus polonicus Evans & Borsuk-Bialynicka, 1998, as well as fishes. The bones are disarticulated but fairly well preserved. The assemblage provides a glimpse of the Early Triassic diversity of small taxa, otherwise poorly known, and has a considerable potential in highlighting the earliest phylogeny of such groups as lepidosauromorphs and salientians which are virtually unknown from other roughly contemporaneous horizons. The Czatkowice microvertebrate community appears to have lived under the mesic conditions of a freshwater oasis with the otherwise arid circumequatorial belt of Scythm Northern Pangea.

Goyocephale lattimorei gen. et sp. n., a new flat-headed pachycephalosaur (Ornlthlschia, Dinosauria) from the Upper Cretaceous of Mongolia

nr 1-4
A new representative of the pachycephalosaur family Homalocephalidae Dong is described, which comes from the Upper Cretaceous deposits of the Gobi Desert, Mongolian People’s Republic. It is more primitive and probably stratigraphically older than Homalocephale calathocercos known from the Upper Cretaceous Nemegt Formation of the Gobi Desert. The diagnosis of H. calathocercos is revised.

New data on the age of the bone breccia from the locality Czatkowice 1 [Cracow Upland, Poland]

nr 1
Fissure deposits are notoriously difficult to date. But, determination of the age of assemblages they contain is crucial for the evolutionary conclusions based on them. The early Mesozoic karst infillings within the Lower Carboniferous limestone of the locality Czatkowice 1 (Southern Poland) containing a diverse terrestrial microvertebrate assemblage (see Borsuk−Białynicka et al. 1999 for review) were originally thought to be most likely Late Permian to Early Triassic in age. Subsequent study of the assemblage containing procolophonids, prolacertiforms, basal lepidosauromorphs, a basal archosaur and small amphibians (including a pre−frog) showed that it is Early Triassic, most probably Late Olenekian, in age because of the advanced dentition pattern of the procolophonids. The discovery of tooth plates of the lungfish Gnathorhiza, known to range from the Induan into early Late Olenekian (Vetlugian Superhorizon to Fedorovskian Horizon of the regional scheme) in Eastern Europe, has further enhanced the dating. The combination of procolophonid and dipnoan evidence now appears to restrict the age of the Czatkowice 1 assemblage to the Early Olenekian.

Avialan status for Oviraptorosauria

Oviraptorosauria is a clade of Cretaceous theropod dinosaurs of uncertain affinities within Maniraptoriformes. All previous phylogenetic analyses placed oviraptorosaurs outside a close relationship to birds (Avialae), recognizing Dromaeosauridae or Troodontidae, or a clade containing these two taxa (Deinonychosauria), as sister taxon to birds. Here we present the results of a phylogenetic analysis using 195 characters scored for four outgroup and 13 maniraptoriform (ingroup) terminal taxa, including new data on oviraptorids. This analysis places Oviraptorosauria within Avialae, in a sister−group relationship with Confuciusornis. Archaeopteryx, Therizinosauria, Dromaeosauridae, and Ornithomimosauria are successively more distant outgroups to the Confuciusornis−oviraptorosaur clade. Avimimus and Caudipteryx are successively more closely related to Oviraptoroidea, which contains the sister taxa Caenagnathidae and Oviraptoridae. Within Oviraptoridae, “Oviraptor” mongoliensis and Oviraptor philoceratops are successively more closely related to the Conchoraptor−Ingenia clade. Oviraptorosaurs are hypothesized to be secondarily flightless. Emended phylogenetic definitions are provided for Oviraptoridae, Caenagnathidae, Oviraptoroidea, Oviraptorosauria, Avialae, Eumaniraptora, Maniraptora, and Maniraptoriformes.
