TLDR
The Joggins Fossil Cliffs site was selected as a UNESCO World Heritage site because of its unparalleled preservation of Pennsylvanian terrestrial organisms in their environmental context as mentioned in this paper, and significant questions remain regarding the Joggin paleoenvironment, including the degree of marine influence.Abstract:
The Joggins Fossil Cliffs site was selected as a UNESCO World Heritage site because of its unparalleled preservation of Pennsylvanian terrestrial organisms in their environmental context. Despite an abundance of research over the past 150 years, significant questions remain regarding the Joggins paleoenvironment, including the degree of marine influence and whether the gymnospermous Cordaites trees may represent the earliest mangroves. Sedimentologic and paleontologic data from interbedded limestone beds indicate open marine conditions in the oldest part of the section, with a waning marine influence up section. Limestone beds, which occur primarily at the base of cycles interbedded with coal and floodplain deposits, are 15–100 cm thick and contain ostracodes, bivalves, and echinoderm fragments. Independent lines of evidence to support a diminishing marine influence in fluvial and coastal deposits with time include: (1) the presence of punctate brachiopods, echinoderm fragments, and ostracodes in...read more

Role of vegetation in shaping Early Pennsylvanian braided rivers: Architecture of the Boss Point Formation, Atlantic Canada
Alessandro Ielpi,Martin R. Gibling,Arden R. Bashforth,Corinne Lally,Michael C. Rygel,Saif Al‐Silwadi +5 more
TL;DR: The Boss Point Formation of Atlantic Canada contains some of the Earth's earliest accumulations of large woody debris as mentioned in this paper, which is a major driver of fluvial dynamics in modern rivers, but few facies models incorporate its influence.

Early Pennsylvanian (Langsettian) fish assemblages from the Joggins Formation, Canada, and their implications for palaeoecology and palaeogeography
TL;DR: A review of all available specimens of fossil fishes from the classic Pennsylvanian Joggins locality of Nova Scotia, Canada, reveals the existence of a diverse community of chondrichthyans (xenacanthids, ctenacanthid and the enigmatic Ageleodus), acanthodians (gyracanthids), sarcopterygians (rhizodontids, megalichthyids, rhizodopsids and dipnoans) and actinoptychius (haplolepids).

Impact of Vegetation On Early Pennsylvanian Fluvial Channels: Insight From the Joggins Formation of Atlantic Canada
TL;DR: In this paper, the authors report evidence for interactions between rivers and in situ vegetation for selected sites in the lower Pennsylvanian Joggins Formation of Atlantic Canada, encompassing fixed, meandering, and distributary channels originally up to 6 m deep.
