Paravian Phylogeny and the Dinosaur-Bird Transition: An Overview
Frontiers in Earth Science, 2019 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 review of the taxonomic composition

, 2012 206 p. : ill. (some col.), maps ; 26 cm.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 avialans. Paraves has over 160 million

PLoS ONE, 2016 Remains of theropod dinosaurs are very rare in Northern Germany because the area was repeatedly submerged by a shallow epicontinental sea during the Mesozoic.

Unenlagiinae revisited: dromaeosaurid theropods from South América
Anais da Academia Brasileira de Ciências, 2011 Over the past two decades, the record of South American unenlagiine dromaeosaurids was substantially increased both in quantity as well as in quality of specimens.

A dromaeosaurid-like claw from the Upper Cretaceous of southern France
, 2022 Dromaeosaurids are poorly known in Europe and their fossil records are mostly postcranial remains. To date, the French faunal records of the family Dromaeosauridae include two taxa: Pyroraptor olympius and Variraptor mechinorum.

Skeletal completeness of the non‐avian theropod dinosaur fossil record
Palaeontology, Volume 62, Issue 6, Page 951-981, November 2019., 2019 Abstract Non‐avian theropods were a highly successful clade of bipedal, predominantly carnivorous, dinosaurs. Their diversity and macroevolutionary patterns have been the subject of many studies. Changes in fossil specimen completeness through time and space can bias our understanding of macroevolution.

The geometry of taking flight: Limb morphometrics in Mesozoic theropods
Journal of Morphology, Volume 276, Issue 2, Page 152-166, February 2015., 2015 ABSTRACT Theropoda was one of the most successful dinosaurian clades during the Mesozoic and has remained a dominant component of faunas throughout the Cenozoic, with nearly 10,000 extant representatives. The discovery of Archaeopteryx provides evidence that avian theropods evolved at least 155 million years ago and that more than half of the tenure of
