Abstract Fieldwork in the Early Cretaceous Jehol Group, northeastern China has revealed a
plethora of extraordinarily well-preserved fossils that are sha** some of the most …

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 …

Progress on the evolutionary origin and diversification of feathers has been hampered by
conceptual problems and by the lack of plesiomorphic feather fossils. Recently, both of these …

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 …

The rice species Oryza sativa is considered to be a model plant because of its small genome
size, extensive genetic map, relative ease of transformation and synteny with other cereal …

Tyrannosauroids are one of the last and the most successful large-bodied predatory
dinosaur groups,,,,, but their early history remains poorly understood. Here we report a new …

Avian genomes are small and streamlined compared with those of other amniotes by virtue
of having fewer repetitive elements and less non-coding DNA,. This condition has been …

In an attempt to investigate differences between the most widely discussed hypotheses of
early tetrapod relationships, we assembled a new data matrix including 90 taxa coded for …

Feathers are highly ordered, hierarchical branched structures, that confer birds with the
ability of flight,,. Discoveries of fossilized dinosaurs in China bearing 'feather-like'structures …
