Body size distribution of the dinosaurs. [PDF]

PLoS ONE, 2012
The distribution of species body size is critically important for determining resource use within a group or clade. It is widely known that non-avian dinosaurs were the largest creatures to roam the Earth.

Dinosaurs from the Santonian–Campanian Atlantic coastline substantiate phylogenetic signatures of vicariance in Cretaceous North America

Royal Society Open Science, 2021
During the Cretaceous, diversifications and turnovers affected terrestrial vertebrates experiencing the effects of global geographical change. However, the poor fossil record from the early Late Cretaceous has concealed how dinosaurs and other ...

Strong support for a heterogeneous speciation decline model in Dinosauria: a response to claims made by Bonsor et al. (2020)

Royal Society Open Science, 2021
Through phylogenetic modelling, we previously presented strong support for diversification decline in the three major subclades of dinosaurs (Sakamoto et al. 2016 Proc. Natl Acad. Sci. USA 113, 5036–5040. (doi:10.1073/pnas.1521478113)).

A new silesaurid from Carnian beds of Brazil fills a gap in the radiation of avian line archosaurs

Scientific Reports, 2023
Comprising the oldest unequivocal dinosauromorphs in the fossil record, silesaurs play an important role in the Triassic radiation of dinosaurs. These reptiles provide the main source of information regarding the ancestral body plan of dinosaurs, as well

Femora from an exceptionally large population of coeval ornithomimosaurs yield evidence of sexual dimorphism in extinct theropod dinosaurs

eLife, 2023
Sexual dimorphism is challenging to detect among fossils due to a lack of statistical representativeness. The Angeac-Charente Lagerstätte (France) represents a remarkable ‘snapshot’ from a Berriasian (Early Cretaceous) ecosystem and offers a unique ...

Dinos and GoPros: Children’s exploratory behaviors in a museum and their reflections on their learning

Frontiers in Psychology, 2023
Research in both laboratory and museum settings suggests that children’s exploration and caregiver–child interaction relate to children’s learning and engagement. Most of this work, however, takes a third-person perspective on children’s exploration of a

So Volcanoes Created the Dinosaurs? A Quantitative Characterization of the Early Evolution of Terrestrial Pan-Aves

Frontiers in Earth Science, 2022
The early Mesozoic is marked by several global-scale environmental events, including the emplacement of large igneous provinces, such as the Siberian Traps, Wrangellia, and Central Atlantic Magmatic Province (CAMP).

New perspectives on head and neck allometry and ecomorphology in tetrapods. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The skull and neck are vital parts of the body, influencing feeding ecology, habitat exploitation and locomotion. Numerous studies have therefore sought to understand how the size of these segments vary with ecology and scale with overall body size.

Dinosaurs, Racial Anxiety, and Curatorial Intervention: Whiteness and Performative Historiography in the Museum

Pamiętnik Teatralny, 2021
This essay argues that the staged encounters between museum visitors and dioramic display of dinosaur fossils in natural history and science museum spaces have been designed to capitalize on and performatively reify white anxiety about the exotic other ...

Using Macro- and Microscale Preservation in Vertebrate Fossils as Predictors for Molecular Preservation in Fluvial Environments

Biology, 2022
Exceptionally preserved fossils retain soft tissues and often the biomolecules that were present in an animal during its life. The majority of terrestrial vertebrate fossils are not traditionally considered exceptionally preserved, with fossils falling ...
