A Jurassic avialan dinosaur from China resolves the
early phylogenetic history of birds
, 2013 The recent discovery of small paravian theropod dinosaurs with well-preserved feathers in the Middle–Late Jurassic Tiaojishan Formation of Liaoning Province (northeastern China) has challenged the pivotal position of Archaeopteryx regarded from its ...Escuillie, F., François Escuillié, Pascal Godefroit, Wu, Wenhao, Andrea Cau, Dyke, G.J., CAU, ANDREA, Dong-Yu, H., Hu, Dong Yu, Gareth, Dyke, Gareth Dyke, François, Escuillié, Hu Dong-Yu, Wu Wenhao, Cau, A., Wenhao, W., Godefroit, P., Pascal, Godefroit +17 morecore +1 more sourcePotential for Powered Flight Neared by Most Close Avialan Relatives, but Few Crossed Its Thresholds [PDF]
, 2020 Uncertainties in the phylogeny of birds (Avialae) and their closest relatives have impeded deeper understanding of early theropod flight. To help address this, we produced an updated evolutionary hypothesis through an automated analysis of the Theropod ...Goloboff, PA, Pei, Rui, Brusatte, Stephen L.; id_orcid, Dececchi, T.
