The theropod furcula [PDF]

open access: yesJournal of Morphology, 2009
AbstractThe furcula is a structure formed by the midline fusion of the clavicles. This is the element which is unique to theropods and is important for understanding the link between birds and other theropods. New specimens from basal theropods suggest that the furcula appeared very early in theropod history.

A Comparison of the Dinosaur Communities from the Middle Jurassic of the Cleveland (Yorkshire) and Hebrides (Skye) Basins, Based on Their Ichnites

open access: yesGeosciences, 2018
Despite the Hebrides and Cleveland basins being geographically close, research has not previously been carried out to determine faunal similarities and assess the possibility of links between the dinosaur populations.

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Bird-like anatomy, posture, and behavior revealed by an early jurassic theropod dinosaur resting trace. [PDF]

open access: yesPLoS ONE, 2009
BackgroundFossil tracks made by non-avian theropod dinosaurs commonly reflect the habitual bipedal stance retained in living birds. Only rarely-captured behaviors, such as crouching, might create impressions made by the hands.

Two new compsognathid-like theropods show diversified predation strategies in theropod dinosaurs. [PDF]

open access: yesNatl Sci Rev
ABSTRACT The Compsognathidae was originally considered an early-diverging clade of coelurosaur theropods. However, recent study suggests that Compsognathidae is not monophyletic. Here, we describe two new compsognathid-like species, Sinosauropteryx lingyuanensis sp. nov. and Huadanosaurus sinensis gen. et sp. nov.

New evidence of feathers in the Crato Formation supporting a reappraisal on the presence of Aves

open access: yesAnais da Academia Brasileira de Ciências, 2011
The preservation of delicate structures such as feathers is very rare in the paleontological record, due to the fragility of their components. Fossil feathers have been reported from approximately 50 deposits around the world, from the Late Jurassic to ...

A methodology of theropod print replication utilising the pedal reconstruction of Australovenator and a simulated paleo-sediment [PDF]

open access: yesPeerJ, 2017
Distinguishing the difference between theropod and ornithopod footprints has proved a difficult task due to their similarities. Herein our aim was to produce a method where a skeleton could be more closely matched to actual fossilised footprints.

Fast-running theropods tracks from the Early Cretaceous of La Rioja, Spain

open access: yesScientific Reports, 2021
Theropod behaviour and biodynamics are intriguing questions that paleontology has been trying to resolve for a long time. The lack of extant groups with similar bipedalism has made it hard to answer some of the questions on the matter, yet theoretical ...
