Molecular development of fibular reduction in birds and its evolution from dinosaurs
(WILEY-BLACKWELL, 2016)
Birds have a distally reduced, splinter-like fibula that is shorter than the tibia. In embryonic development, both skeletal elements start out with similar lengths. We examined molecular markers of cartilage differentiation ...
New developmental evidence clarifies the evolution of wrist bones in the dinosaur-bird transition

Developmental evolution of the distal ankle in the dinosaur–bird transition
(Wiley-liss, div John Wiley & Sons Inc., 2020-12)
The adult ankle of early reptiles had five distal tarsal (dt) bones, but in Dinosauria, these were reduced to only two: dt3 and dt4, articulated to metatarsals (mt) mt3 and mt4. Birds have a single distal tarsal ossification ...
Developmental evolution of the distal ankle in the dinosaur-bird transition
(Wiley, 2020)

The earliest bird-line archosaurs and the assembly of the dinosaur body plan
(Nature Publishing Group, 2017-04)
The relationship between dinosaurs and other reptiles is well established, but the sequence of acquisition of dinosaurian features has been obscured by the scarcity of fossils with transitional morphologies. The closest ...
Paravian phylogeny and the dinosaur-bird transition: An overview
(Frontiers Media S.A., 2019-02)
Recent years witnessed the discovery of a great diversity of early birds as well as closely related non-avian theropods, which modified previous conceptions about the origin of birds and their flight. We here present a ...

The origin and evolutionary consequences of skeletal traits shaped by embryonic muscular activity, from basal theropods to modern birds
(2017)
Embryonic muscular activity (EMA) is involved in the development of several distinctive traits of birds. Modern avian diversity and the fossil record of the dinosaur-bird transition allow special insight into their evolution. ...
