2017 In Archosaur Paleontology

The year 2017 in archosaur paleontology was eventful. Archosaurs include the only living dinosaur group — birds — and the reptile crocodilians, plus all extinct dinosaurs, extinct crocodilian relatives, and pterosaurs. Archosaur palaeontology is the scientific study of those animals, especially as they existed before the Holocene Epoch began about 11,700 years ago. The year 2017 in paleontology included various significant developments regarding archosaurs.

This article records new taxa of fossil archosaurs of every kind that have been described during the year 2017, as well as other significant discoveries and events related to paleontology of archosaurs that occurred in the year 2017.

* A study on the method allowing estimation of wing loading and Aspect ratio (aeronautics), aspect ratio in Mesozoic birds and on flight modes that were possible for Mesozoic birds is published by Serrano ''et al.'' (2017).
* A study on whether sternal keel length and ilium length were correlated in bird evolution, based on data from extant birds and Mesozoic birds, is published by Zhao, Liu and Li (2017).
* A study on the impact of varying oxygen concentrations, global temperatures and air densities on the flight performance of extinct birds and on major diversification events which took place during the evolution of birds is published by Serrano ''et al.'' (2017).
* A study on the Shoulder girdle, pectoral girdle morphology of Mesozoic birds and its implications for the evolution of the avian flight musculature (specifically the Bird anatomy#Muscular system, supracoracoideus muscle) is published by Gerald Mayr, Mayr (2017).
* A study on the morphological characteristics and evolution of the pygostyle and tail feathers in Early Cretaceous birds and closely related non-avian theropods is published by Wang & O'Connor (2017).
* A study on the postnatal skeletal development of limb bones in four species of extant aquatic birds (the streaked shearwater, the Japanese cormorant, the black-tailed gull and the rhinoceros auklet) and its implications for the assessment of ontogenetic stage of fossil and skeletal bird specimens is published by Watanabe (2017).
* A study estimating values of body weight, wing span and wing area of the trackmakers of the Cretaceous Ichnotaxon, ichnotaxa ''Archaeornithipus meijidei'', ''Hwangsanipes choughi'' and ''Yacoraitichnus avis'' is published by Tanaka (2017).
* The presence of the Atlas (anatomy), atlas rib in ''Archaeopteryx'' is reported for the first time by Tsuihiji (2017).
* A tooth attributed to an Archaeopterygidae, archaeopterygid bird is described from the Early Cretaceous of France by Louchart & Pouech (2017).
* A well-preserved skull of a juvenile specimen of ''Sapeornis chaoyangensis'' is described by Wang ''et al.'' (2017), preserving what the authors consider to be the complete dentition.
* A study on the flight capabilities of ''Sapeornis chaoyangensis'' is published by Serrano & Luis M. Chiappe, Chiappe (2017).
* A study on the relationship between the oxygen isotope composition of bird bone phosphate and that of the drinking water of birds, as well as on implications of applying the discovered equation to ''Confuciusornis'' and to the Miocene and Pliocene
