Dinosaurs reveal the geographical signature of an evolutionary radiation [PDF]

, 2018
Dinosaurs dominated terrestrial ecosystems across the globe for over 100 million years and provide a classic example of an evolutionary radiation. However, little is known about how these animals radiated geographically to become globally distributed ...

Basal paravian functional anatomy illuminated by high-detail body outline [PDF]

, 2017
Body shape is a fundamental expression of organismal biology, but its quantitative reconstruction in fossil vertebrates is rare. Due to the absence of fossilized soft tissue evidence, the functional consequences of basal paravian body shape and its ...

Cranial ontogenetic variation in early saurischians and the role of heterochrony in the diversification of predatory dinosaurs [PDF]

, 2016
Non-avian saurischian skulls underwent at least 165 million years of evolution and shapes varied from elongated skulls, such as in the theropod Coelophysis, to short and box-shaped skulls, such as in the sauropod Camarasaurus.

Potential for Powered Flight Neared by Most Close Avialan Relatives, but Few Crossed Its Thresholds [PDF]

, 2020
Uncertainties in the phylogeny of birds (Avialae) and their closest relatives have impeded deeper understanding of early theropod flight. To help address this, we produced an updated evolutionary hypothesis through an automated analysis of the Theropod ...

The impact of poor sampling of polymorphism on cladistic analysis

Cladistics, 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 Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

De l’exclusion à l’exil Les Paravents , de Jean Genet

Études théâtrales, 2023
En 1983, au terme de sa vie, Jean Genet confie à Layla Shahid : « j’ai été écrasé par le concept de France ». Très précise, la formule apporte un éclairage rétrospectif remarquable sur sa trajectoire personnelle et, par conséquent, sur son œuvre : ce qu’elle place au premier plan, ce n’est pas son exclusion de et par la communauté qui l’a vu naître ...

Feather development genes and associated regulatory innovation predate the origin of Dinosauria [PDF]

, 2014
The evolution of avian feathers have recently been illuminated by fossils and the identification of genes involved in feather patterning and morphogenesis. However, molecular studies have focused mainly on protein-coding genes. Using comparative genomics

An insect †Archaeopteryx: Cretaceous amber fossil elucidates the evolution of complex host detection and ovipositor mechanisms in parasitoid woodwasps (Hymenoptera: Orussoidea)

Systematic Entomology, Volume 50, Issue 3, Page 630-645, July 2025.
We describe †Cretovelona orussopteryx n. gen. & sp. from Kachin amber. The fossil is examined with synchrotron scanning and integrated into an existing morphological data set for Orussoidea. This fossil parasitoid wasp displays a unique character combination demonstrating intermediate conditions in evolving the complex features employed in echo ...
