There is no consensus on when in the fish-tetrapod transition suction feeding, the primary method of prey capture in the aquatic realm, evolved into the direct biting on prey typical of terrestrial animals. Here, we show that differences in the morphology of selected cranial sutures between species that span the fish–tetrapod transition (the Devonian osteolepiform fish Eusthenopteron, the aquatic Devonian tetrapod Acanthostega, and the Permian terrestrial tetrapod Phonerpeton) can be used to…

Feeding biomechanics in Acanthostega and across the fish–tetrapod transition

It is concluded that Acanthostega retained a primitively aquatic lifestyle and did not possess cranial adaptations for terrestrial feeding, suggesting a slow tempo of morphological and biomechanical changes in the transition from Devonian tetrapod jaws to aquatic/semi-aquatic Carboniferous tetrapid jaws.

Terrestrial capture of prey by the reedfish, a model species for stem tetrapods

The mechanism of terrestrial prey‐capture in reedfish was identified and it was showed that this species uses a lifted trunk and downward inclined head to capture ground‐based prey, remarkably similar to the mechanism described earlier for eel‐catfish.

3D Bite Modeling and Feeding Mechanics of the Largest Living Amphibian, the Chinese Giant Salamander Andrias davidianus (Amphibia:Urodela)

The skull biomechanics of the Chinese giant salamander, Andrias davidianus is investigated using 3D finite element analysis and reveals that the prey contact position is crucial for the structural performance of the skull, which is probably related to the lack of a bony bridge between the posterior end of the maxilla and the anterior quadrato-squamosal region.

Ontogenetic plasticity in cranial morphology is associated with a change in the food processing behavior in Alpine newts

The results could indicate that early tetrapods, in analogy to salamanders, may have developed new feeding mechanisms in their aquatic environment and that these functional innovations may have later paved the way for terrestrial feeding mechanisms.

Temnospondyli bite club: ecomorphological patterns of the most diverse group of early tetrapods

The skull analysis reveals a concordance between form and feeding function, in amphibious and fully aquatic feeders in temnospondyls, which could be consequences of adaptative or phylogenetical constraints.

Transitions from Water to Land: Terrestrial Feeding in Fishes

This chapter shows how these fishes establish and maintain a stable body posture to allow the capture of food in the terrestrial environment, how their jaws grab the ground-based food, and how this food is transported to the back of the mouth cavity.

Biomechanics and hydrodynamics of prey capture in the Chinese giant salamander reveal a high-performance jaw-powered suction feeding mechanism

Computational fluid dynamics simulations indicate that the viscerocranial elements mainly serve to accommodate the water that was given a sufficient anterior-to-posterior impulse beforehand by powerful jaw separation, and it is hypothesized that this modified way of generating suction is primitive for salamanders.

The feeding system of Tiktaalik roseae: an intermediate between suction feeding and biting

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.

Late to the table: diversification of tetrapod mandibular biomechanics lagged behind the evolution of terrestriality.

The substantial temporal gap between the origin of postcranial features associated with terrestriality, such as limbs with functional elbow/knee and wrist/ankle joints capable of weight-bearing, and the onset of divergence in jaw biomechanics provides a compelling example of "functional modularity" during a major adaptive radiation.

Aquatic–terrestrial transitions of feeding systems in vertebrates: a mechanical perspective

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.



Fish-like gills and breathing in the earliest known tetrapod

The discovery of a fish-like branchial skeleton in Acanthostega gunnari, from the Upper Devonian of East Greenland, one of the earliest tetrapods known, provides information on the sequence of acquisition of tetrapod characters, and supports previous suggestions that such characters as legs with digits evolved first for use in water.

A Devonian tetrapod-like fish and the evolution of the tetrapod body plan

The discovery of a well-preserved species of fossil sarcopterygian fish from the Late Devonian of Arctic Canada that represents an intermediate between fish with fins and tetrapods with limbs, and provides unique insights into how and in what order important tetrapod characters arose is reported.

In vivo cranial suture function and suture morphology in the extant fish Polypterus: implications for inferring skull function in living and fossil fish

Micro-computed tomography scans of the experimental specimens indicate that the interfrontal and frontoparietal sutures, typically loaded in tension, are less interdigitated in cross section than the interparietal suture, which experiences compression, consistent with published correlations of suture form and function in mammals.


Adult anatomy and patterns of development in frogs and salamanders support their origin from different families of dissorophoid labyrinthodonts, and the ancestry of amniotes apparently lies among very early anthracosaurs.

This review summarizes major advances made and reevaluates alternative interpretations of important parts of the evidence of the fish‐tetrapod transition, and discusses each of these steps with respect to inferred functional utility of acquired character sets.

The First Tetrapod Finds from the Devonian (Upper Famennian) of Latvia

The lower jaw of Ventastega is strikingly primitive in retaining fangs on the coronoid series, but shares many characters with those of other known Devonian tetrapods, and some of these features are interpreted as basal tetrapod synapomorphies.

Lower jaws, lower tetrapods–a review based on the Devonian genus Acanthostega

Abstract The lower jaw of the Devonian tetrapod Acanthostega is described for the first time. Redescriptions are provided for the lower jaws of the elpistostegid Panderichthys, the Devonian tetrapods

Comparative morphology and functional interpretation of the sutures in the dermal skull roof of temnospondyl amphibians

In all temnospondyls studied, the median plane and the margin of the skull roof show a nearly uniform sutural morphology; the circumorbital region is most complex.


This book is a timely, well written addition to the paleontological literature, and represents an outstanding effort to introduce the reader to the rather complicated story of the origin of fourlimbed vertebrates and their gradual, initial colonization of land.
