Egg shape changes at the theropod–bird transition, and a morphometric study of amniote eggs [PDF]
Royal Society Open Science, 2014 The eggs of amniotes exhibit a remarkable variety of shapes, from spherical to elongate and from symmetrical to asymmetrical. We examine eggshell geometry in a diverse sample of fossil and living amniotes using geometric morphometrics and linear ...

Forelimb biomechanics in the derived therizinosaur Nothronychus and its relation to the origin of the avian wing [PDF]
Scientific ReportsTherizinosauria is a clade of extinct unusual maniraptoran theropods. Nothronychus is a derived representative of the clade from the upper Cretaceous Moreno Hill Formation, west-central New Mexico and Tropic Shale, southern Utah.

Cranial functional specialisation for strength precedes morphological evolution in Oviraptorosauria [PDF]
Communications BiologyOviraptorosaurians were a theropod dinosaur group that reached high diversity in the Late Cretaceous. Within oviraptorosaurians, the later diverging oviraptorids evolved distinctive crania which were extensively pneumatised, short and tall, and had a ...

Bite and tooth marks on sauropod dinosaurs from the Morrison Formation [PDF]
PeerJ, 2023 Tooth-marked bones provide important evidence for feeding choices made by extinct carnivorous animals. In the case of the dinosaurs, most bite traces are attributed to the large and robust osteophagous tyrannosaurs, but those of other large carnivores ...

New theropod remains and implications for megaraptorid diversity in the Winton Formation (lower Upper Cretaceous), Queensland, Australia [PDF]
Royal Society Open Science, 2020 The holotype specimen of the megaraptorid Australovenator wintonensis, from the Upper Cretaceous Winton Formation (Rolling Downs Group, Eromanga Basin) of central Queensland, is the most complete non-avian theropod found in Australia to date.

FIRST THEROPOD RECORD FROM THE MARINE BATHONIAN OF JAISALMER BASIN, TETHYAN COAST OF GONDWANAN INDIA
Rivista Italiana di Paleontologia e Stratigrafia, 2023 Middle Jurassic theropods have a scanty record worldwide, especially from Gondwana. In India, where Jurassic theropods are particularly rare and only represented by a few isolated teeth and some badly preserved bones, there is currently no record of ...

The non-avian theropod quadrate I: standardized terminology with an overview of the anatomy and function [PDF]
PeerJ, 2015 The quadrate of reptiles and most other tetrapods plays an important morphofunctional role by allowing the articulation of the mandible with the cranium.

Incremental growth of therizinosaurian dental tissues: implications for dietary transitions in Theropoda [PDF]
PeerJ, 2017 Previous investigations document functional and phylogenetic signals in the histology of dinosaur teeth. In particular, incremental lines in dentin have been used to determine tooth growth and replacement rates in several dinosaurian clades.
