Abstract Biomechanical models illustrate how the principles of physics and physiology determine function in organisms, allowing ecological inferences and functional predictions to be based on morphology. Dynamic lever and linkage models of the mechanisms of the jaw and skull during feeding in fishes predict function from morphology and have been used to compare the feeding biomechanics of diverse fish groups, including fossil taxa, and to test ideas in ecological morphology. Here we perform… 
Using linkage models to explore skull kinematic diversity and functional convergence in arthrodire placoderms
TLDR
High levels of kinematic transmission among arthrodire taxa suggest the potential for rapid gape expansion and possible suction feeding, and Morphological comparisons indicate that there were several morphological solutions for obtaining these fast kinematics, which allowed different taxa to achieve similar kinemata while varying other aspects of the feeding apparatus.
Functional Morphology and Biomechanics of Feeding in Fishes
TLDR
Recent advances in understanding of fish feeding anatomy, behavior, and function are reviewed, with a focus on progress in cranial biomechanics in fishes.
Linkage mechanisms in the vertebrate skull: Structure and function of three‐dimensional, parallel transmission systems
TLDR
New, three‐dimensional (3D), parallel linkage models of the skulls of birds and fishes are presented and used to investigate structure–function relationships in these systems, enabling novel interpretations of the mechanics of force transmission across a diversity of vertebrate feeding mechanisms and enhancing the understanding of musculoskeletal function and evolution.
Eating with a saw for a jaw: Functional morphology of the jaws and tooth‐whorl in Helicoprion davisii
TLDR
The morphology of the jaws and tooth‐whorl is used to reconstruct the jaw musculature and develop a biomechanical model of the feeding mechanism in these early Permian predators, suggesting that Helicoprion was better equipped for feeding on soft‐bodied prey.
Common evolutionary trends underlie the four‐bar linkage systems of sunfish and mantis shrimp
TLDR
This work built dynamic linkage models of 19 centrarchid and 36 stomatopod species and used phylogenetic generalized least squares regression (PGLS) to compare evolutionary shifts in linkage morphology and mechanical outputs derived from the models, illustrating the potential influence of physical principles on morphological evolution across biological systems with different structures, behaviors, and ecologies.
Ecomorphological inferences in early vertebrates: reconstructing Dunkleosteus terrelli (Arthrodira, Placodermi) caudal fin from palaeoecological data
TLDR
A useful comparative framework established on extant taxa is proposed for predicting some anatomical aspects in extinct aquatic vertebrates from palaeoecological data and vice versa, and suggests a caudal fin with a well-developed ventral lobe, narrow peduncle and wide span, in contrast to classical reconstructions founded on the phylogenetic proximity with much smaller placoderms known from complete specimens.
Muscle Moment Arm Analyses Applied to Vertebrate Paleontology: A Case Study Using Stegosaurus stenops Marsh, 1887
TLDR
A case study for calculating three-dimensional muscle moment arms using Stegosaurus stenops Marsh, 1887 is presented to highlight both the potential and the limitations of this approach in vertebrate paleontology and finds the technique to be mostly insensitive to choices in muscle modeling parameters.
High-performance suction feeding in an early elasmobranch
TLDR
The cranial skeleton of one of the earliest known stem elasmobranchs, Tristychius arcuatus from the Middle Mississippian of Scotland is analyzed and the feeding apparatus is revealed as highly derived, capable of substantial oral expansion, and with clear potential for high-performance suction feeding some 50 million years before the earliest osteichthyan equivalent.

Feeding mechanics and bite force modelling of the skull of Dunkleosteus terrelli, an ancient apex predator
TLDR
A biomechanical model of force and motion during feeding in Dunkleosteus terrelli reveals a highly kinetic skull driven by a unique four-bar linkage mechanism that is among the most powerful bites in animals.

TLDR
This study examines the diversity of mechanical design of the oral jaws in 35 species of ray-finned fishes to analyze lower jaw lever models in a broad phylogenetic range of taxa and identify the origin and evolutionary patterns of change in the linkage systems that power maxillary rotation and upper jaw protrusion.

Evolution of hindlimb posture in nonmammalian therapsids: biomechanical tests of paleontological hypotheses

TLDR
A biomechanical model is derived to test the hypothesis that the use of multiple postures was ancestral to the more upright posture typical of most mammals, and indicates that the axial rotation of the femur typical in sprawling locomotion can reduce peak bending stresses.
Comparative and developmental functional morphology of the jaws of living and fossil gars (Actinopterygii: Lepisosteidae)
TLDR
Principal components analysis of functionally important morphometrics shows that several gar species occupy different regions of functional morphospace, although gars occupy a range of biomechanical states across the continuum of force vs. velocity transmission.
Transmission of force and velocity in the feeding mechanisms of labrid fishes (Teleostei, Perciformes)
TLDR
The feeding mechanisms of four species of the teleostean family Labridae were modeled using four-bar linkage theory from mechanical engineering to calculate the capacity for transmission of force and velocity in musculoskeletal systems.

Feeding mechanics of teleost fishes (Labridae; Perciformes): A test of four‐bar linkage models
TLDR
A previously unidentified four‐bar chain was found to be an accurate model of the mechanism by which upper jaw protrusion, maxillary rotation, and gape increase occur in Cheilinus.
Aquatic prey capture in ray‐finned fishes: A century of progress and new directions
TLDR
The history of functional morphological analyses of suction feeding in ray‐finned fishes is traced, with a particular focus on the mechanisms by which suction is generated, and new data using a novel flow imaging technique that enables quantification of the water flow field into the mouth are presented.
A quantitative theory of expected volume changes of the mouth during feeding in teleost fishes
TLDR
A model of the initial mouth shape which is actually found in many ‘generalized’ fishes is found, and demands concerning volume and physiological cross-sectional area of the muscles involved are compared with model predictions.
