“…Palaeosauropus is also known from Visean trackways in the Mauch Chunk Formation near Pottsville, Pennsylvania (Fillmore et al 2009). Lucas et al (2010) documented wide variation in the print morphology of Palaeosauropus primaevus depending on epirelief and substrate variation.…”

The ichnological fossil record has previously provided key evidence for the diversification of land vertebrates (tetrapods) during the Carboniferous Period, following the invasion of the land. Within the UK, tetrapod ichnofossils from the late Carboniferous of the English Midlands are well documented, but few such fossils are known from earlier in the period. We present a rare ichnological insight into early Carboniferous tetrapod diversification in the United Kingdom based on a Viseanaged specimen collected from an interdistributary trough palaeoenvironment at Hardraw Scar, Wensleydale, North Yorkshire. This specimen represents the stratigraphically oldest known tetrapod trackway from the UK. We refer this specimen to Palaeosauropus sp., providing the earliest known occurrence of an edopoid temnospondyl. Supplementing the sparse record of contemporary body fossils from the early Carboniferous, this provides further insights into the diversification of temnospondyl amphibians across Euramerica.Supplementary material: A 3D model of the plaster cast produced from the trackway specimen is available at https://doi.org/ 10.5519/0022377 and a lower resolution version is available on Sketchfab (https://skfb.ly/6OAxR).

“…Our recent collecting of trace fossils in the Mauch Chunk Formation in the Mount Carbon-Tumbling Run Reservoir area indicates that traces are abundant in the upper part of the middle member of the Mauch Chunk Formation (Fillmore et al, 2009). Many of these traces are in clay-draped sandstones similar to RPM 77-32-1, so we infer that its likely stratigraphic provenance is the upper part of the middle member of the Mauch Chunk Formation.…”

Temnocorpichnus isaacleai is a new ichnogenus and ichnospecies of temnospondyl amphibian body impression from the Mississippian (Visean) Mauch Chunk Formation of eastern Pennsylvania, UnitedStates. The shovel-shaped head, robust limbs, relatively short trunk and smooth integument diagnose the ichnotaxon and readily distinguish it from Hermundurichnus and Sauropleura, the only other named body impressions of Paleozoic tetrapods. Temnocorpichnus is a compound ichnogenus in which the footprint ichnogenus Batrachichnus is a behaviorally distinct component. The temnospondyl identity of Temnocorpichnus adds to the sparse and earliest records of temnspondyls, which are of Visean age. The smooth integument of the ichnogenus does not support the presence of ventral scales or armor in the earliest temnospondyls, but body proportions of the Mauch Chunk body impressions indicate a relatively terrestrial temnospondyl not matched by any taxon now known from bones. Three closely associated impressions ofTemnocorpichnus on a single bedding plane suggest some sort of gregarious behavior in Mississippian temnospondyls and may support speculation that internal fertilization and associated courtship behavior evolved independently in one group of amphibians more than 300 million years ago.

Volume 39The Topics in Geobiology series covers the broad discipline of geobiology that is devoted to documenting life history of the Earth. A critical theme inherent in addressing this issue and one that is at the heart of the series is the interplay between the history of life and the changing environment. The series aims for high quality, scholarly volumes of original research as well as broad reviews.Geobiology remains a vibrant as well as a rapidly advancing and dynamic fi eld. Given this fi eld's multidiscipline nature, it treats a broad spectrum of geologic, biologic, and geochemical themes all focused on documenting and understanding the fossil record and what it reveals about the evolutionary history of life. The Topics in Geobiology series was initiated to delve into how these numerous facets have infl uenced and controlled life on Earth.Recent volumes have showcased specifi c taxonomic groups, major themes in the discipline, as well as approaches to improving our understanding of how life has evolved.Taxonomic volumes focus on the biology and paleobiology of organisms -their ecology and mode of life -and, in addition, the fossil record -their phylogeny and evolutionary patterns -as well as their distribution in time and space.Theme-based volumes, such as predator-prey relationships, biomineralization, paleobiogeography, and approaches to high-resolution stratigraphy, cover specifi c topics and how important elements are manifested in a wide range of organisms and how those dynamics have changed through the evolutionary history of life. Comments or suggestions for future volumes are welcomed.
