A New Oviraptorid Dinosaur (Dinosauria: Oviraptorosauria) from the Late Cretaceous of Southern China and Its Paleobiogeographical Implications. [PDF]

open access: yesSci Rep, 2015
AbstractThe Ganzhou area of Jiangxi Province, southern China is becoming one of the most productive oviraptorosaurian localities in the world. A new oviraptorid dinosaur was unearthed from the uppermost Upper Cretaceous Nanxiong Formation of Ganzhou area.

Using creation science to demonstrate evolution 2: morphological continuity within Dinosauria [PDF]

open access: yes, 2011
Creationist literature claims that sufficient gaps in morphological continuity exist to classify dinosaurs into several distinct baramins (‘created kinds’).

Skeletal completeness of the non‐avian theropod dinosaur fossil record

open access: yesPalaeontology, 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 impact of poor sampling of polymorphism on cladistic analysis

open access: yesCladistics, Volume 32, Issue 3, Page 317-334, June 2016., 2016
Abstract Despite its ubiquity in the natural world, polymorphism is commonly disregarded or poorly sampled in phylogenetic analyses due to deliberate sampling strategy, inadequate sampling effort and limited specimen availability. Poor sampling of intraspecific variation engenders differential sampling of morphs within polymorphic species, which could ...

The geometry of taking flight: Limb morphometrics in Mesozoic theropods

open access: yesJournal 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

Morphology and osteohistology of a large‐bodied caenagnathid (Theropoda, Oviraptorosauria) from the Hell Creek Formation (Montana): implications for size‐based classifications and growth reconstruction in theropods [PDF]

open access: yesPapers in Palaeontology, 2020
AbstractOviraptorosaurs, like many coelurosaurians, are frequently diagnosed using incomplete or fragmentary skeletal remains, with factors such as body size often used to assign material to a particular taxon or as a basis for describing new species.

Avialan status for Oviraptorosauria [PDF]

open access: yes, 2002
Oviraptorosauria is a clade of Cretaceous theropod dinosaurs of uncertain affinities within Maniraptoriformes. All previous phylogenetic analyses placed oviraptorosaurs outside a close relationship to birds (Avialae), recognizing Dromaeosauridae or ...
