The functional anatomies of avian finger joints have never been compared with those of the basal avian Archaeopteryx lithographica or maniraptoran theropod dinosaurs. These startling oversights are due to unfamiliarity of the joints outside of highly specialised studies of bird-wing biomechanics. Here fleshed to skeletonised repeated-measures analyses of finger-joint ranges of motion (ROMs) in a basal palaeognath, the Ostrich Struthio camelus, were utilised as a model to begin filling in these… Expand

ROM mapping of ligamentous constraints on avian hip mobility: implications for extinct ornithodirans
TLDR
Nearly 95% of the joint poses predicted to be possible at the hip based on osteological manipulation were rendered impossible by ligamentous constraints, casting doubt on the ‘batlike’ hip pose traditionally inferred for pterosaurs and basal maniraptorans, and underscores that reconstructions of joint mobility based on manipulations of bones alone can be misleading.

Comparative digestive physiology of archosaurs with notes on bird origins
TLDR
Coprolites of early archosaurs contain undigested bones, which suggests a short digestion time and higher metabolic rates than in extant crocodiles, and implies reappearance and strong development of a specific stomach functionality that either had been already lost in the theropod dinosaurs or was never present in their lineage.

A coordinate-system-independent method for comparing joint rotational mobilities
TLDR
A new method for plotting joint poses, inspired by a 16th century map projection, allows coordinate-system-independent measurements of joint mobility and enables accurate comparative studies of joint function. Expand
A Practical Guide to Measuring Ex vivo Joint Mobility Using XROMM

  • 2020
TLDR
This paper aims to serve as a practical guide by walking through each step of the ex vivo XROMM process: how to acquire and prepare cadaveric specimens, how to manipulate specimens to collect X-ray data, and how to use these data to compute joint rotational mobility. Expand

The asymmetry of the carpal joint and the evolution of wing folding in maniraptoran theropod dinosaurs
TLDR
The radiale angle was small in primitive coelurosaurs but considerably larger in primitive maniraptorans, indicating that the radiale was more wedge-shaped and the carpal joint more asymmetric, an early advantage of the flexible, asymmetric wrist inherited by birds. Expand
The wing musculature of the Weka (Gallirallus australis), a flightless rail endemic to New Zealand
TLDR
The pectoral musculature of the Weka, a flightless New Zealand rail, is almost identical with that of a volant relative, the American coot, even to details of the propatagial complex, which raises serious doubts on the validity of reconstructing the musculatures of extinct vertebrates. Expand
Quadrupedal Dinosaurs did not Evolve Fully Pronated Forearms: New Evidence from the Ulna
TLDR
This test provides the first functional explanation for the convergent responses of quadrupedal archosaurs to their misaligned forearm joints, and provides a foundation for elucidating why the quadruPedal evolution of archosaur forelimbs diverged from those of therians and chameleons. Expand
Anatomy of the primitive bird Sapeornis chaoyangensis from the Early Cretaceous of Liaoning, China
Two new, nearly completely articulated skeletons of Sapeornis chaoyangensis provide much new information about the anatomy of this basal avian, particularly in the skull, pectoral girdle, forelimb,Expand
Forelimb joint mobility and the evolution of wing-propelled diving in birds
-We measured wing joint mobility in penguins, alcids, diving-petrels, and nondiving fliers. Great reduction in mobility of the intrinsic wing joints was found in penguins, but not in alcids orExpand
An examination of forearm bone mobility in Alligator mississippiensis (Daudin, 1802) and Struthio camelus Linnaeus, 1758 reveals that Archaeopteryx and dromaeosaurs shared an adaptation for gliding and/or flapping
TLDR
A functional analysis of forearm bone mobility in extant archosaurs shows that crossing and uncrossing of the radius and ulna can be forced in alligators via a passive gliding mechanism recently described in lacertilians, while birds are adapted to inhibit this motion. Expand
Bird-Like Anatomy, Posture, and Behavior Revealed by an Early Jurassic Theropod Dinosaur Resting Trace
TLDR
The manus impressions corroborate that early theropods, like later birds, held their palms facing medially, in contrast to manus prints previously attributed to theropod that have forward-pointing digits. Expand
COMPARISON OF FORELIMB FUNCTION BETWEEN DEINONYCHUS AND BAMBIRAPTOR (THEROPODA: DROMAEOSAURIDAE)
TLDR
The morphology and range of motion in the forelimbs of Deinonychus and Bambiraptor enable two-handed prehension with the wrist flexed, one-handed clutching of objects to the chest, use of the hand as a hook, arm-swinging or -raising displays, andUse of theForelimbs to maintain balance. Expand
Using the American alligator and a repeated-measures design to place constraints on in vivo shoulder joint range of motion in dinosaurs and other fossil archosaurs
TLDR
Investigation of whether soft tissues affect the more mobile shoulder joint in the same manner in which they affect elbow joint ROM in an extant archosaur results show that the ROMs of humeral flexion and extension, as well as abduction and adduction, both show a statistically significant increase as flesh is removed, but then decrease when the bones must be physically articulated and moved.

Complete forelimb myology of the basal theropod dinosaur Tawa hallae based on a novel robust muscle reconstruction method
TLDR
This study presents new hypotheses of homology for the distal limb musculature of archosaurs and provides the first complete reconstruction of dinosaurian forelimb musculatures, including the antebrachial and intrinsic manual muscles. Expand
