Abstract Skeletal remains attributable to large dissorophoid amphibians, including four femora, two humeri, and an isolated palatine bone, have recently been recovered from the Lower Permian fissure fill deposits at Richards Spur, Oklahoma. Three of the femora are assignable to Acheloma cumminsi. One humerus represents an indeterminate trematopid, perhaps A. cumminsi, whereas the remaining humerus and femur are evidently of dissorophid origin and probably assignable to Cacops. The palatine bone… 

A New Lower Permian Amphibamid (Dissorophoidea, Temnospondyli) from the Fissure Fill Deposits Near Richards Spur, Oklahoma

A phylogenetic analysis of 17 ingroup taxa and 62 cranial and postcranial characters yielded a single most-parsimonious tree with the new taxon in a monophyletic Amphibamidae as the sister taxon to the Lower Triassic Micropholis from South Africa.

A new Lower Permian trematopid (Temnospondyli: Dissorophoidea) from Richards Spur, Oklahoma

A new trematopid amphibian, Acheloma dunni, is reported based on excellently preserved cranial and postcranial elements recovered from the Lower Permian fissure fill deposits of the Dolese Brothers Co. limestone quarry near Richards Spur, Oklahoma, which may represent the top predator of the Richards Spur assemblage.

The armoured dissorophid Cacops from the Early Permian of Oklahoma and the exploitation of the terrestrial realm by amphibians

The skull of C. morrisi has several features associated with predatory behaviour, indicating that this dissorophid may have been one of the top terrestrial predators of its time.

AN EARLY PERMIAN VARANODONTINE VARANOPID (SYNAPSIDA: EUPELYCOSAURIA) FROM THE RICHARDS SPUR LOCALITY, OKLAHOMA

Abstract Description of the first varanodontine varanopid material from the highly fossiliferous limestone fissure fill deposits at Richards Spur (Dolese Brothers Limestone Quarry), Oklahoma, is

New specimen of Cacops woehri indicates differences in the ontogenetic trajectories among cacopine dissorophids

A large specimen of the dissorophid Cacops woehri is described, which was previously only known from the juvenile or subadult holotype skull, and shows that, in contrast to C. morrisi and C. aspidephorus, C. woeHri only undergoes relatively subtle changes in skull morphology in late ontogeny and retains the overall more gracile morphology into adult stages.

A new microsaur (Tetrapoda: Lepospondyli) from the Lower Permian of Richards Spur (Fort Sill), Oklahoma

Bolterpeton carrolli n.gen. n.sp. is described from the Lower Permian fissure-fill deposits of Richards Spur, Oklahoma. Bolterpeton is united with the gymnarthrid microsaur Cardiocephalus by having

Microleter mckinzieorum gen. et sp. nov. from the Lower Permian of Oklahoma: the basalmost parareptile from Laurasia

A phylogenetic analysis, using both parsimony and Bayesian algorithms, of Palaeozoic parareptiles indicates that Microleter falls fairly basally, between the millerettids and the group including Acleistorhinus and lanthanosuchids, with interesting implications for biogeography.

OROMYCTER, A NEW CASEID FROM THE LOWER PERMIAN OF OKLAHOMA

Abstract Superbly preserved skeletal elements of the new taxon Oromycter dolesorum from the Lower Permian deposits in the Dolese Quarry, near Richards Spur, Oklahoma, record the earliest known

The Lower Permian Amphibamid Doleserpeton (Temnospondyli: Dissorophoidea), The Interrelationships of Amphibamids, and the Origin of Modern Amphibians

Doleserpeton adds to the strong evidence for a temnospondyl origin of batrachians, particularly for anurans, and the hypothesis proposing a lepospondylorigin of modern amphibians is questioned.

A New Species of Dissorophid (Cacops woehri) from the Lower Permian Dolese Quarry, Near Richards Spur, Oklahoma

A new species of Cacops woehri is described on the basis of a well-preserved skull from the Dolese Quarry locality in Oklahoma (Leonardian), with variation encompassing a distinct cranial morphology.

The cranial morphology and taxonomy of the saurerpetontid Isodectes obtusus comb. nov. (Amphibia: Temnospondyli) from the Lower Permian of Texas

Five saurerpetontid temnospondyl amphibian specimens from the Lower Permian Arroyo Formation of Baylor County, Texas are redescribed under the binomen Isodectes obtusus comb, with some of the resemblances described by Watson appearing to be artefacts of crushing of an individual specimen.

Dissorophoid relationships and ontogeny, and the origin of the Lissamphibia

  • J. Bolt
  • Biology, Environmental Science
  • 1977
A three-stage dentitional ontogenetic sequence for Doleserpeton and Tersomius is proposed, in which the third (adult) phase is similar to the adult of most other labyrinthodonts, the second (juvenile) phase resembles the adult condition in lissamphibians whereas the hypothetical first (larval)phase resembles the larvae of salamanders and oviparous caecilians.

A new trematopsid amphibian (Temnospondyli: Dissorophoidea) from the Lower Permian of Texas

Phonerpeton is interpreted as a small, lightly built, terrestrially adapted carnivore, and is distinguished by the presence of a semilunar curvature of the squamosal, domed parietals, an unossified sphenethmoid, long and slender mid-dorsal ribs, and a radius with a semicircular cross section.

Permo-Carboniferous Paleoecology and Morphotypic Series

The “trends” of evolutionary change from Hylonomus to Thrinaxodon can best be seen if these two and Haptodus are used as an evolutionary series, the stages that are missing interpolated, and the roles of the other genera evaluated on the basis of this more or less idealized, conceptual series.

MULTICINCTUS, AND ADAPTATIONS AND PHYLOGENY OF THE FAMILY DISSOROPHIDAE

  • R. Demar
  • Biology, Environmental Science
  • 1968
A hypothesis based on degree of ossification, kinds of coexisting species, and manner of preservation, suggests that the Dissorophidae evolved ever increasing terrestrial adaptation and that the armor evolved, at least twice within the family, as one response to demands of the new environment.

The Family Trematopsidae

The family Trematopsidae is expanded to include the genus Acheloma as well as Trematops. The former occurs in the Wichita and Putnam formations of Texas, while the latter is found in the Clear Fork

THE EVOLUTION OF A PERMIAN VERTEBRATE CHRONOFAUNA

The term chronofauna 1 is proposed to differentiate faunal units in which time is an important factor from those in which it is not, and to gain information concerning both physical and biological aspects of environment adequate to provide a background for study of many phases of adaptive modifications of animals.
