Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Sauropods stomping theropods: a much neglected theme in palaeo-art

open access: yes, 2011
Needless to say, one of the things I love most about Paco's Brontomerus artwork is that it's a rare and welcome example of the much neglected Sauropods Stomping Theropods school of palaeo-art.

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.

Flapping before Flight: High Resolution, Three-Dimensional Skeletal Kinematics of Wings and Legs during Avian Development. [PDF]

open access: yesPLoS ONE, 2016
Some of the greatest transformations in vertebrate history involve developmental and evolutionary origins of avian flight. Flight is the most power-demanding mode of locomotion, and volant adult birds have many anatomical features that presumably help ...

Allosaurus europaeus (Theropoda: Allosauroidea) Revisited and Taxonomy of the Genus

open access: yesDiversity
Allosaurus is one of the most famous theropod dinosaurs, but the validity and relationships between the different species have been confusing and often questioned.

New contributions to the skull anatomy of spinosaurid theropods: Baryonychinae maxilla from the Early Cretaceous of Igea (La Rioja, Spain)

open access: yes, 2022
Spinosaurid dinosaurs show a wide geographical and temporal distribution, being present in Gondwanan and Laurasian landmasses, at least, during the Lower Cretaceous and the Cenomanian.

Paleobiogeographic evolution and distribution of Carcharodontosauridae (Dinosauria, Theropoda) during the middle Cretaceous of North Africa

open access: yesPapéis Avulsos de Zoologia, 2018
Over the last few decades, the systematics and evolution of carcharodontosaurids, a group of large predatory dinosaurs, from North Africa have been better understood mainly due the discovery of new species.

The fast and the frugal: Divergent locomotory strategies drive limb lengthening in theropod dinosaurs.

open access: yesPLoS ONE, 2020
Limb length, cursoriality and speed have long been areas of significant interest in theropod paleobiology, since locomotory capacity, especially running ability, is critical in the pursuit of prey and to avoid becoming prey.

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

The geometry of taking flight: limb morphometrics in Cretaceous theropods

open access: yes, 2014
Theropoda was one of the most successful dinosaurian clades during the Mesozoic and has remained a dominant component of faunas throughout the Cenozoic, with nearly 10,000 extant representatives.
