Devonian tetrapod tracks and trackways can be recognized by three criteria: morphology of the manus and pes impressions that matches known Devonian tetrapod skeletal morphology, manus smaller than pes, and the alternating trackway pattern that results from lateral sequence walking in quadrupedal tetrapod locomotion. The first reported Devonian tetrapod track, named Thinopus antiquus, from Pennsylvania, is not a tetrapod track and is likely an impression of a fish coprolite(s). A critical review…

ABSTRACT The hypothesis that tetrapods evolved from elpistostegids during the Frasnian, in a predominantly aquatic context, has been challenged by the discovery of Middle Devonian tetrapod trackways
Non-marine palaeoenvironment associated to the earliest tetrapod tracks
A new palaeoenvironmental interpretation of the track-bearing interval from Zachełmie is presented, showing that it represents a succession of ephemeral lakes with a restricted and non-marine biota, rather than a marginal marine environment as originally thought.
Baraminological analysis of Devonian and Carboniferous tetrapodomorphs
According to evolutionary theory, the origin of tetrapods (or limbed vertebrates) from a fish-like ancestor during the Devonian Period was one of the major events in the history of life. Devonian
Triassic turtle tracks and the origin of turtles
Abstract Turtle (Testudines) tracks, Chelonipus torquatus, reported from the early Middle Triassic (Anisian) of Germany, and Chelonipus isp. from the late Early Triassic (Spathian) of Wyoming and
Passive-Dynamic Walkers of the Late Paleozoic
Abstract. Two upper Permian trackways attributed to the ichnogenus Sukhonopus, regarded as pareiasaurian, have been studied. The longer trackway includes 15.5 locomotor cycles. Statistical analysis
Timing of dicynodont extinction in light of an unusual Late Triassic Polish fauna and Cuvier’s approach to extinction
ABSTRACT Dicynodont therapsids are prominent elements of Triassic continental faunas, but the date of their demise is controversial, linked either to end-Carnian faunal turnover or to end-Triassic

Tetrapod trackways from the early Middle Devonian period of Poland
Well-preserved and securely dated tetrapod tracks from Polish marine tidal flat sediments of early Middle Devonian (Eifelian stage) age are presented, forcing a radical reassessment of the timing, ecology and environmental setting of the fish–tetrapod transition, as well as the completeness of the body fossil record.
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.
The postcranial skeleton of the Devonian tetrapod Tulerpeton curtum Lebedev
A cladistic analysis indicates that Tulerpeton is a reptiliomorph stem-group amniote and the earliest known crown-group tetrapod: Acanthostega and Ichthyostega are successively more derived plesion stem- group tetrapods and do not consititute a monophyletic ichthyostegalian radiation.
Postcranial stem tetrapod remains from the Devonian of Scat Craig, Morayshire, Scotland
A recently discovered postorbital bone from the site is, strictly speaking, indeterminable but may belong to Elginerpeton; it broadly resembles the postorbitals of Ichthyostega and Acanthostega, and demonstrates that the typical stem tetrapod facial morphology had evolved before the end of the Frasnian.
Postcranial stem tetrapod remains from the Devonian of Scat Craig, Morayshire, Scotland
Overall, the postcranial bones combine apparent synapomorphies with Ichthyostega and characters which are uniquely primitive among stem-group tetrapods, which demonstrates that the typical stem tetrapod facial morphology had evolved before the end of the Frasnian.
Behavioral evidence for the evolution of walking and bounding before terrestriality in sarcopterygian fishes
The findings suggest that some fundamental features of tetrapod locomotion, including pelvic limb gait patterns and substrate association, probably arose in sarcopterygians before the origin of digited limbs or terrestriality, and it follows that the attribution of some of the nondigited Devonian fossil trackways to limbed tetrapods may need to be revisited.
The Mississippian Tetrapod Footprint Ichnogenus Palaeosauropus: Extramorphological Variation and Ichnotaxonomy
Palaeosauropus primaevus is a tetrapod footprint ichnotaxon first described from the Upper Mississippian (Visean) Mauch Chunk Formation near Pottsville, Pennsylvania, United States. Our relocation of
Middle Devonian invertebrate trace fossils from the marginal marine carbonates of the Zachełmie tetrapod tracksite, Holy Cross Mountains, Poland
The dolomitic deposits of the Middle Devonian Wojciechowice Formation exposed at the tetrapod tracksite in the Zachelmie Quarry in the Holy Cross Mountains (Poland) are characterised by a low
The pectoral fin of Panderichthys and the origin of digits
A CT scan study of an undisturbed pectoral fin of Panderichthys is presented demonstrating that the plate-like ‘ulnare’ of previous reconstructions is an artefact and that distal radials are in fact present and makes a strong case for fingers not being a novelty of tetrapods but derived from pre-existing distal Radials present in all sarcopterygian fish.
