Theoretical models of theropod forelimb biomechanics are often tainted with preconceived ideas. Actualistic modeling using specimens and casts, coupled with CAT-scans and dissections of extant vertebrate forelimbs, demonstrates that forelimb motion in theropods is considerably less than hypothetical models indicate. The forelimbs ofCoelophysis, cf.Coelurus, Allosaurus, Deinonychus, andTyrannosaurus were investigated. Motion at the shoulder, elbow, wrist, and digits were analyzed and compared… 

Forelimbs of the theropod dinosaur Dilophosaurus wetherilli: Range of motion, influence of paleopathology and soft tissues, and description of a distal carpal bone

Experiments on American alligator cadavers show that ROM exhibits limited intraspecific variation and is greater in the fullyfleshed elbow than skeletal manipulation suggests, and this work adjusts the results of the bare-bones manipulations to account for the known influence of soft tissues.

The muscular anatomy of the pectoral girdle and forelimb of Nothronychus is reconstructed using visible muscle scars, data from extant birds and crocodilians, and models for other theropods, and results were quite similar to those inferred for dromaeosaurs.


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.

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.


This kinematic study of Ornitholestes uses manual manipulations of forelimb casts to determine range of motion and finds high elbow flexion is present in maniraptoriform coelurosaurs but not in basal theropods.

Forearm Range of Motion in Australovenator wintonensis (Theropoda, Megaraptoridae)

range of motion analysis neither confirms nor refutes current phylogenetic hypotheses with regards to the placement of Megaraptoridae; however, it is noted Australovenator possessed, not only a similar forearm range of motion to some maniraptorans and basal coelurosaurs, but also similarities with Tetanurans (Allosauroids and Dilophosaurus).

Forelimb Posture in Chilesaurus diegosuarezi (Dinosauria, Theropoda) and Its Behavioral and Phylogenetic Implications

The arrangement of the forelimb bones in Chilesaurus could show the first evidences of the structures linked to the muscles that flex the forearms, features related with the acquisition of flying control in advanced maniraptorans.

The evolutionary continuum of limb function from early theropods to birds

It is emphasised that many false dichotomies or categories have been applied to theropod form and function, and sometimes, these impede research progress, and a combination of techniques that emphasises integration of neontological and palaeontological evidence and quantitative assessment of limb function cautiously applied with validated techniques and sensitivity analysis of unknown variables are needed.

The role of the forelimb in prey capture in the Late Triassic reptile Megalancosaurus (Diapsida, Drepanosauromorpha)

The new functional interpretation fits well with the overall body architecture of Megalancosaurus’ skeleton, suggesting that this reptile was an ambush predator that may have assumed a stable tripodal position, secured by the hooked tail and hind limbs, freeing its forelimbs to catch prey by sudden extension of the arm and firm grasping with the pincer-like digits.

The Predatory Ecology of Deinonychus and the Origin of Flapping in Birds

“stability flapping” is described, a novel behaviour executed for positioning and stability during the initial stages of prey immobilisation, which may have been pivotal to the evolution of the flapping stroke.



The pectoral girdle and forelimb of the basal theropod Herrerasaurus ischigualastensis

ABSTRACT New specimens of Herrerasaurus ischigualastensis shed light on the structure and function of the pectoral girdle and forelimb in early theropod dinosaurs. As in tetanurian theropods, the

Theropod forelimb design and evolution

Despite the dramatically different forces imparted by the evolution of flight, forelimb proportions of basal birds are only slightly different from those of their non-avian relatives, and theoretical predictions based on five biomechanical and developmental factors are introduced.

Adductors, abductors, and the evolution of archosaur locomotion

Fossil theropods document the stepwise evolution of a novel mechanism of limb adduction/abduction involving long-axis rotation of the femur, which accounts for the conspicuous absence of significant musculature ventral and dorsal to the hip joint in extant birds.

Functional osteology of the avian wrist and the evolution of flapping flight

The avian wrist is extraordinarily adapted for flight. Its intricate osteology is constructed to perform four very different, but extremely important, flight‐related functions. (1) Throughout the

Homoplasy and the evolution of dinosaur locomotion

This work surveys hindlimb and pelvic anatomy across non-avian dinosaurs and analyzes these within a cladistic framework to quantify patterns of change within the locomotor apparatus to identify where homoplasy constitutes parallelism and may thereby be used to infer similar selective pressures on hind Limb function.

On the presence of furculae in some non-maniraptoran theropods

DINO 11541 is closely related to Allosaurus and the presence of a furcula suggests that Allosaurus also had afurcula and that elements previously described as Allosaurus gastralia from the Cleveland-Lloyd Dinosaur Quarry are actually a growth series of furculae.

The contractile properties of the M. supracoracoideus In the pigeon and starling: a case for long-axis rotation of the humerus

It is proposed that, at the downstroke-upstroke transition, variable levels of co-contraction of the M. pectoralis and SC interact to provide a level of kinematic control at the shoulder that would not be possible were the two antagonists to work independently.

New evidence concerning avian origins from the Late Cretaceous of Patagonia

A theropod dinosaur from Patagonia is described, Unenlagia comahuensis gen. et sp.

The pelvic musucJature of the dinosaur Hypsilophodon (Reptilia: Ornithischia)

Evidence is provided to show that: 1) the prepubic process, diagnostic of an ornithischian, did not provide the main support for the abdomen; 2) the abdomen was large and extended ventral to the

The origin and early evolution of birds

There is no evidence for a major or mass extinction of birds at the end of the Cretaceous, nor for a sudden ‘bottleneck’ in diversity that fostered the early Tertiary origination of living bird ‘Orders’.
