Synopsis A new, large compsognathid theropod, Huaxiagnathus orientalis gen. et sp. nov., from the Early Cretaceous Yixian Formation deposits of Liaoning Province, People's Republic of China is described. The holotype specimen is nearly complete, lacking only the distal portion of the tail. It is the second largest theropod taxon discovered from Jehol Group sediments. Like all compsognathids, Huaxiagnathus has short forelimbs and a relatively unspecialised coelurosaur body plan. Previously… 

A Small Derived Theropod from Öösh, Early Cretaceous, Baykhangor Mongolia

Abstract A new theropod dinosaur, Shanag ashile, from the Early Cretaceous Öösh deposits of Mongolia is described here. The new specimen (IGM 100/1119) comprises a well-preserved right maxilla,

A new caudipterid from the Lower Cretaceous of China with information on the evolution of the manus of Oviraptorosauria

A new caudipterid species Xingtianosaurus ganqi is described, providing new morphological information on early manual evolution of Oviraptorosauria, and giving new light on the evolution of radiale angle among Coelurosauria.

A NEW OCCURRENCE OF SMALL THEROPOD TRACKS IN THE HOUCHENG(TUCHENGZI) FORMATION OF HEBEI PROVINCE, CHINA

Small theropod footprints have been known from the Jurassic-Cretaceous boundary strata of northeastern China for several decades,although these ichnofossils have been overshadowed by the feathered

The systematic position of the enigmatic theropod dinosaur Yixianosaurus longimanus

The hypothesis that Y. longimanus is a basal paravian is consistent with the probable presence of pennaceous feathers in this taxon, and avoids implying a complicated evolutionary history for the maniraptoran forelimb.

On the manual morphology of Compsognathus longipes and its bearing on the diagnosis of Compsognathidae

This work provides the first detailed study of the morphology of the manus of Compsognathus longipes and identifies a unique suite of metacarpal I morphologies that are used to diagnose a subclade among species often referred to as ‘CompsognATHidae’.

A Basal Coelurosaur (Dinosauria: Theropoda) from the Late Jurassic (Oxfordian) of the Shishugou Formation in Wucaiwan, People's Republic of China

A cladistic analysis of Zuolong salleei in a broadly sampled theropod data matrix recovers it as a basal coelurosaur, making it one of the oldest coel Kurosaur fossils yet known that preserves both cranial and postcranial bones.

Theropod teeth from the basalmost Cretaceous of Anoual (Morocco) and their palaeobiogeographical significance

Abstract The theropod teeth from the Berriasian (Early Cretaceous) site of Anoual (N Morocco) are described. The assemblage is important in that it comes from one of the very few dinosaur sites of

A New Genus and Species of Sapeornithidae from Lower Cretaceous in Western Liaoning, China

Sapeornithidae is a basal pygostylian family of Early Cretaceous primitive birds, in which only one genus and species, Sapeornis chaoyangensis, was reported before, but according to the phylogenetic analyses, both Didactylornis gen. nov. and SapeORNis form a sister group, which is basal to the clade formed by Confuciusornis and all the more derived birds.

A new carnivorous dinosaur from the Late Jurassic Solnhofen archipelago

A cladistic analysis indicates that the new theropod dinosaur described from the Late Jurassic period of Schamhaupten in southern Germany is closer to maniraptorans than to tyrannosauroids, grouping it with taxa often considered to be compsognathids.

This is the first mature non-avian dinosaur to be found that is smaller than Archaeopteryx, and it eliminates the size disparity between the earliest birds and their closest non-Avian theropod relatives.

Morphometric analysis indicates that the arctometatarsalian structure is significantly more elongate and gracile than underived metatarsi, and this structure is associated with relatively elongate distal hind limbs per unit femoral length.
