A distal tibiotarsus from the Upper Cretaceous of Sinpetru, Hateg Basin, Romania was originally described as belonging to the supposed pelecaniform bird Elopteryx but more recently various authors have proposed that it might belong to a non-maniraptoran tetanuran, ornithomimid, troodontid, dromaeosaurid or strigiform. None of these identifications withstand scrutiny. The recognition of a shared derived character and strong similarity of the specimen to the distal tibiotarsi of members of the… 

Figures from this paper

A distal right femur from the La Scoabă locality, Sinpetru, is reminiscent in size and features of the femora described initially by Andrews, but several osteological details differentiate the specimen from other fossil and Recent steganopodes, suggesting that it does not, in fact, belong to a bird.
A fast-growing basal troodontid (Dinosauria: Theropoda) from the latest Cretaceous of Europe
Bone histology shows that it was an actively growing subadult when it died but may have had a growth pattern in which it grew rapidly in early ontogeny and attained a subadult size quickly, and it is hypothesized that it could have migrated from Asia to reach the Ibero-Armorican island no later than Cenomanian or during the Maastrichtian dispersal events.
New alvarezsaurid (Dinosauria, Theropoda) from uppermost Cretaceous of north-western Patagonia with associated eggs
It is suggested that plesiomorphic alvarezsaurids survived in Patagonia until the latest Cretaceous, whereas these basal forms became extinct elsewhere.
A Short-Armed Troodontid Dinosaur from the Upper Cretaceous of Inner Mongolia and Its Implications for Troodontid Evolution
The discovery of Linhevenator suggests that derived troodontids have independently evolved a highly specialized pedal digit II and have significantly shortened the forelimb over the course of their evolution.
The Osteology of Balaur bondoc, an Island-Dwelling Dromaeosaurid (Dinosauria: Theropoda) from the Late Cretaceous of Romania
ABSTRACT The Haţeg Island fauna of the terminal Late Cretaceous (ca. 71–65 million years ago) of Romania is one of the most unusual dinosaur assemblages in the global fossil record. It has long been
A New Coelurosaurian Theropod from the La Buitrera Fossil Locality of Río Negro, Argentina
Abstract A new coelurosaurian theropod, Alnashetri cerropoliciensis, is reported here based on articulated hind limbs of a single individual discovered at the locality of La Buitrera (Candeleros
Non-avian theropod dinosaurs from the early Late Cretaceous of central Europe
Abstract Quantitative and qualitative analyses of isolated teeth and postcranial elements of non-avian theropod dinosaurs from the Upper Cretaceous (Santonian) Csehbanya Formation, Iharkut (western
Trierarchuncus prairiensis gen. et sp. nov., the last alvarezsaurid: Hell Creek Formation (uppermost Maastrichtian), Montana
Abstract The enigmatic Alvarezsauria (Dinosauria: Theropoda) are characterized by extremely short forelimbs with a single functional digit bearing a large, robust ungual. Alvarezsauria are first
Ceratonykus oculatus gen. et sp. nov., a new dinosaur (?Theropoda, Alvarezsauria) from the Late Cretaceous of Mongolia
A new dinosaur, Ceratonykus oculatus gen. et sp. nov. (Parvicursoridae, Alvarezsauria), from the Upper Cretaceous (Baruungoyot Formation) of Mongolia is described based on a fragmentary skeleton. It
A new alvarezsaurid dinosaur from the Nemegt Formation of Mongolia
Three new alvarezsaurid specimens from the Nemegt Formation of Mongolia are reported, which were associated with each other and also with multiple oviraptorid skeletons in a small multi-species assemblage.


Neuquenornis volans, a new Late Cretaceous bird (Enantiornithes: Avisauridae) from Patagonia, Argentina
ABSTRACT A new genus and species of Late Cretaceous (Coniancian–Santonian) birds, Neuquenornis volans, is described. This new taxon is known from a fairly complete, articulated specimen from the Rio
An unusual oviraptorosaurian dinosaur from China
Oviraptorosaurians are an unusual group of theropod dinosaurs, with highly specialized skulls. Here we report a new oviraptorosaurian, Incisivosaurus gauthieri, gen. et sp. nov., from the lowest part
A new specimen of Shuvuuia deserti Chiappe et al., 1998, from the Mongolian Late Cretaceous with a discussion of the relationships of alvarezsaurids to other theropod dinosaurs
A partial skeleton of an immature individual of the alvarezsaurid mononykine theropod Shuvuuia deserti from the Late Cretaceous (Campanian) Tögrögiin Shiree locality of southern Mongolia exhibits a
A basal troodontid from the Early Cretaceous of China
The discovery of Sinovenator and the examination of character distributions along the maniraptoran lineage indicate that principal structural modifications toward avians were acquired in the early stages of manIRaptoran evolution.
New latest Cretaceous microvertebrate fossil assemblages from the Haţeg Basin (Romania)
Late Cretaceous terrestrial ecosystems in southern Europe are relatively poorly known, although much progress has been made during the past decade, principally with regard to the microvertebrate
The skull of a relative of the stem-group bird Mononykus
The configuration of the temporal region of the skull and its articulation with the rostrum indicate the capability for prokinetic movement in which flexing occurs at the junction of the upper jaw and neurocranium, and support the idea that prokinesis preceded other types of avian intracranial kinesis.
Flightless bird from the Cretaceous of Mongolia
Several features suggest that Mononychus olecranus is more closely related to modern birds than is Archaeopteryx lithographica, and suggests that the early radiation of avialians is only beginning to be sampled.
Anatomy of Patagonykus puertai (Theropoda, Avialae, Alvarezsauridae), from the Late Cretaceous of Patagonia
ABSTRACT The fragmentary skeleton of a new Late Cretaceous avialan theropod from Patagonia is described. Patagonykus puertai possesses caudal trunk vertebrae that are slightly convex caudally. The
The first known alvarezsaurid (Theropoda: Aves) from North America
The description of Mononykus olecranus from the Upper Cretaceous of Mongolia and its interpretation as a bird by Perle et al. (1993a, b; 1994) stirred much excitement and continuing controversy
The evolution of dinosaurs.
The ascendancy of dinosaurs on land near the close of the Triassic now appears to have been as accidental and opportunistic as their demise and replacement by therian mammals at the end of the
