Coelurosauria is the most diverse clade of theropod dinosaurs. Much of this diversity is
present in Paraves—the clade of dinosaurs containing dromaeosaurids, troodontids, and …

Previously described feathered dinosaurs reveal a fascinating record of feather evolution,
although substantial phylogenetic gaps remain. Here we report the occurrence of feathers in …

The early evolution of the major groups of derived non-avialan theropods is still not well
understood, mainly because of their poor fossil record in the Jurassic. A well-known result of …

Archaeopteryx is widely accepted as being the most basal bird, and accordingly it is
regarded as central to understanding avialan origins; however, recent discoveries of derived …

Abstract The Late Cretaceous was a time of tremendous global change, as the final stages
of the Age of Dinosaurs were shaped by climate and sea level fluctuations and witness to …

The recent discovery of small paravian theropod dinosaurs with well-preserved feathers in
the Middle–Late Jurassic Tiaojishan Formation of Liaoning Province (northeastern China) …

Theropods have traditionally been assumed to have lost manual digits from the lateral side
inward, which differs from the bilateral reduction pattern seen in other tetrapod groups. This …

Isolated theropod teeth are some of the most common fossils in the dinosaur fossil record
and are continually reported in the literature. Recently developed quantitative methods have …

Background Australia's dinosaurian fossil record is exceptionally poor compared to that of
other similar-sized continents. Most taxa are known from fragmentary isolated remains with …

The tyrannosauroid fossil record is mainly restricted to Cretaceous sediments of Laurasia,
although some very fragmentary Jurassic specimens have been referred to this group,. Here …
