Thinopus and a Critical Review of Devonian Tetrapod Footprints

  title={Thinopus and a Critical Review of Devonian Tetrapod Footprints},

  pages={136 - 154}
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… Expand

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 trackwaysExpand
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. Expand
Ichnology and depositional environment of the Middle Devonian Valentia Island tetrapod trackways, south-west Ireland
Abstract Nine tetrapod trackways are described from the Middle Devonian continental Valentia Slate Formation on the north-eastern coast of Valentia Island in County Kerry, Ireland. The trackwaysExpand
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. DevonianExpand
Trackways Produced by Lungfish During Terrestrial Locomotion
Terrestrial locomotion of a 35 cm African lungfish (Protopterus annectens; Dipnoi: Sarcopterygii) is recorded on compliant sediment, bearing some similarity to fossil traces interpreted as footprints. Expand
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 andExpand
Non-tetrapod trace fossils from the Middle Devonian tetrapod tracksite at Zachełmie Quarry, Holy Cross Mountains, Poland
Abstract The Middle Devonian (Eifelian) dolomites exposed in the Zachelmie Quarry (Holy Cross Mountains, southern Poland) contain the earliest fossil record of tetrapods. Low-diversity, but uniqueExpand
Defining the morphological quality of fossil footprints. Problems and principles of preservation in tetrapod ichnology with examples from the Palaeozoic to the present
Abstract The morphology of fossil footprints is the basis of vertebrate footprint ichnology. However, the processes acting during and after trace fossil registration which are responsible for theExpand
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 analysisExpand
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-TriassicExpand


Devonian tetrapod trackways and trackmakers; a review of the fossils and footprints
Abstract The earliest tetrapods are known from the Upper Devonian. Their remains are becoming better known from increasing numbers of specimens, localities, environments and ichnofossils. Each of theExpand
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. Expand
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. Expand
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. Expand
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. Expand
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. Expand
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. Expand
Trackways of Tetrapod Vertebrates from the Upper Devonian of Victoria, Australia
THREE distinct trackways of tetrapod vertebrates were discovered late in 1971 by one of us (N. A. W.) in strata of the Genoa River Beds at lat. 37° 19′ S, long. 149° 23′ E, in eastern Victoria,Expand
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.

Woodland Hypothesis for Devonian Tetrapod Evolution
The rarity of Devonian tetrapods and the absence of tetrapods during the first 14 million years of the Mississippian (Romer’s Gap) have inspired hypotheses of fish-tetrapod evolutionary transition asExpand
