The fossil Tiktaalik roseae from the Late Devonian induces clear definition of the biomechanical and functional preconditions for a terrestrial lifestyle including quadrupedal standing and locomotion on limbs. Therefore, we determined the internal stresses in this model organism under the influence of gravity using the finite element method. Stress patterns during symmetrical two-forelimb support result from bending of trunk and neck. During asymmetrical one-forelimb support, as occurs during… Expand
Positional strategy of trunk muscles among aquatic, semi-aquatic and terrestrial species in Urodela
TLDR
The findings suggest that in the middle section, larger dorsal muscles for stiffening the back to maintain posture and larger abdominal muscles are responsible for balancing the body weight while it is supported by the limbs in the more terrestrial species. Expand
Structure and function of the septum nasi and the underlying tension chord in crocodylians
TLDR
It is proposed that the newly identified strand of tissue extends longitudinally below the septum nasi acts as an active tension chord necessary for stabilizing the long rostrum of crocodilians during biting by transforming the high bending stress of the rostral into moderate compressive stress.

Comparative limb bone loading in the humerus and femur of the tiger salamander: testing the ‘mixed-chain’ hypothesis for skeletal safety factors
TLDR
Safety factors against skeletal failure differ between the forelimbs and hindlimbs of salamanders; this may relate to differing locomotor roles, potentially bearing on the invasion of land by vertebrates. Expand
The biomechanical construction of the horse's body and activity patterns of three important muscles of the trunk in the walk, trot and canter
TLDR
EMG data confirmed exactly what has been predicted by theoretical analysis of the biomechanics of the trunk under static conditions, and also confirmed the importance of the vertebral column stabilisation by the ipsilateral m. Expand
Aquatic–terrestrial transitions of feeding systems in vertebrates: a mechanical perspective
TLDR
Any aquatic vertebrate aiming for a terrestrial lifestyle must change from its aquatic to a terrestrial feeding mechanism, and the mechanical challenges associated with such aquatic–terrestrial transitions in vertebrates are synthesized. Expand
Feeding in Crocodylians and Their Relatives: Functional Insights from Ontogeny and Evolution
TLDR
Context is provided for interpreting how the development and evolution of performance are thought to have shaped the vertebrate head—as informed by the deep evolutionary history of living crocodylians and their fossil precursors. Expand
The feeding system of Tiktaalik roseae: an intermediate between suction feeding and biting
TLDR
It is shown that a key intermediate, Tiktaalik roseae, was capable of cranial kinesis despite significant restructuring of the skull to facilitate biting and snapping, and might have been an important intermediate step in the evolution of terrestrial feeding systems by maintaining suction-generation capabilities while simultaneously elaborating a mechanism for biting-based prey capture. Expand
Elpistostege and the origin of the vertebrate hand
TLDR
It is suggested that the vertebrate hand arose primarily from a skeletal pattern buried within the fairly typical aquatic pectoral fin of elpistostegalians, and is potentially the sister taxon of all other tetrapods, and its appendages further blur the line between fish and land vertebrates. Expand
The evolution of the tetrapod humerus: morphometrics, disparity, and evolutionary rates
TLDR
The macroevolutionary dynamics of shape changes in the humeri of all major grades and clades of early tetrapods and their fish-like forerunners are explored, indicating sustained changes in humeral shape in the deepest portion of the tetrapod stem group and certain portions of the crown. Expand
Evolutionary Homology in the Fin-To-Limb Transition: Evaluating the Morphology of Foramina in a Late Devonian Humerus from the Catskill Formation, Clinton County, Pennsylvania
TLDR
The internal morphology of ANSP 21350 is reconstructed using micro-computed tomography scan data, and an evolutionary pathway for the ventral ridge foramina is presented that incorporates the existing tetrapodomorph fossil record. Expand

Relationship between scapular position and structural strength of rib cage in quadruped animals
TLDR
The result of this simulation showed that the “thoracic” ribs of quadrupeds, to which the serratus muscles attach, have a relatively higher strength against compaction than the other ribs, which implies that the location of robust ribs is associated with the arrangement of theserratus muscle, and provides a probable candidate for determination of the scapular position for extinct quadruped archosaurs and mammals.

Mechanical stress as the main factor in skull design of the fossil reptile Proterosuchus (Archosauria)

The aim of this study of the crocodile-like fossil Proterosuchus is to obtain a simplified model, which is, in shape and internal structure, as close as possible to the natural counterpart. Expand
Biomechanical investigations on the skulls of reptiles and mammals
The skulls of reptiles and mammals can be loaded mechanically in three ways: the weight of the head acting downward, perhaps reinforced by a prey or bunch of food lifted from the ground or waterExpand

Thermal physiology and the origin of terrestriality in vertebrates
TLDR
It is hypothesized that the physiological advantages of thermoregulation were a major selective force that resulted in the increasing capacity for the ancestors of tetrapods to move into shallow water, and later to support their bodies against the force of gravity and increase the size and locomotor capacities of the limbs.
