Recent discoveries in Asia have greatly increased our understanding of the evolution of dinosaurs’ integumentary structures, revealing a previously unexpected diversity of “protofeathers” and feathers. However, all theropod dinosaurs with preserved feathers reported so far are coelurosaurs. Evidence for filaments or feathers in noncoelurosaurian theropods is circumstantial and debated. Here we report an exceptionally preserved skeleton of a juvenile megalosauroid, Sciurumimus albersdoerferi n…

The phylogenetic analysis recovers Fukuivenator as a basally branching maniraptoran theropod, yet is unable to refer it to any known coelurosaurian subgroups, and highlights the high levels of homoplasy in coeluraosaurian evolution.

Kulindadromeus zabaikalicus, a basal neornithischian dinosaur from the Jurassic of Siberia, preserves diverse integumentary structures, including monofilaments, more complex protofeather structures and scales on its tail and distal parts of its limbs, suggesting that integumental features were diversified even in ornithischians.

The placement of J. starki in multiple phylogenetic positions and differences in the morphological interpretation of filamentous feathers found in basal coelurosaurs produce contrasting reconstructions of character evolution that will need to be resolved in due course if greater clarity is to be obtained in this area.

A seemingly feathery nontheropod dinosaur from the Jurassic of Siberia shows that feathers were not unique to the ancestors of birds and may even have been quite widespread, and feathers may thus have been present in the earliest dinosaurs.

Phylogenetic relationships of the Cretaceous Gondwanan theropods Megaraptor and Australovenator: the evidence afforded by their manual anatomy
- Biology
- 2016
Megaraptor and Australovenator are devoid of several manual features that the basal tyrannosauroid Guanlong shares with more derived coelurosaurs (e.g., Deinonychus), thus countering the own previous hypothesis that Megaraptora is well nested within Tyrannosauroidea.
