Variation in the postcranial pneumaticity in derived titanosaurs (Dinosauria: Sauropoda)

Historical Biology
Currently, only birds have a pneumatic system, but in the past, this was common among several ornithodirans. Within Titanosauria, it was the saltasaurines that showed a high degree of postcranial pneumaticity.

Avemetatarsalia and the Origin of Dinosauria

2022
This chapter looks into early avemetatarsalians and the origin of Dinosauria. From the period of late Triassic and Mesozoic, Avemetatarsalia is a large and diverse clade including many familiar extinct vertebrates, such as pterosaurs and non-avian dinosaurs like birds. Moreover, Avemetatarsalians decoupled the functions of the fore and hindlimbs, which

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

Journal of Evolutionary Biology, 2011
Creationist literature claims that sufficient gaps in morphological continuity exist to classify dinosaurs into several distinct baramins (‘created kinds’).

The Phylogeny of Ceratosauria (Dinosauria: Theropoda)

Journal of Systematic Palaeontology, 2008
Synopsis Recent discoveries and analyses have drawn increased attention to Ceratosauria, a taxonomically and morphologically diverse group of basal theropods. By the time of its first appearance in the Late Jurassic, the group was probably globally distributed.
