..., and most accurate, when applied to species that are abundant in the assemblage. The Devonian Fossil Gorge, near Coralville, Iowa, USA, is an approximately 12-meter-thick section that exposes the surfaces of Givetian (Mid-Devonian) limestones of the Rapid and Solon Members of the Little Cedar...

... 1 is 5 m, 12 m, and 2.5 m thick at the Nammal Gorge, Gundi section and Lakrakki Nala section respectively ( Figs 3 – 5 ). It consists of interbedded sandy limestone and shale along with few fossils of productus and makes the basal part of the formation at all studied sections ( Figs 3 – 5 , 6a...

...—in this case a continuous carbonate platform succession—also provides taphonomic control ( Bottjer and Jablonski, 1988 ). Figure 1. Geologic map showing Windjana Gorge within Late Devonian reef complexes of north Canning basin, northwestern Australia, after Playford (1980) and George et al. (1997...

...) is barren of fossils and could as easily be included in the Mississippian as in the Devonian. J. J. Stevenson, in 1878, 27 first proposed the idea of a hiatus in this area by which a large part of the Upper Devonian section was removed. He based this belief on the identification of certain fossils...

... growth relationships of the biota reveal a fascinating array of complex ecological interactions and relationships that form a style of reef that appears to be quite unique in the fossil record. A snorkler exploring the shallows of Windjana Gorge in the Famennian would have been presented...

...NAT P. STEPHENS; DAWN Y. SUMNER Abstract Renalcids are a problematic group of mostly Paleozoic microbial fossils. In the Upper Devonian reef complex of the Canning Basin, Western Australia, they grew in cryptic reef environments, such as the undersides of laminar stromatoporoids during Frasnian...

... a; MacNaughton et al. 2019 ; Shillito & Davies, 2019 a , b ). In younger strata, deposited around the Silurian–Devonian boundary, unequivocal instances of fully non-marine trace fossil communities occur (Minter et al. 2016 b , 2017; Buatois & Mángano, 2018 ); their environmental preferences...

.... These hypotheses and Romer’s Gap are tested here using depth to calcic horizon in paleosols of the northern Appalachians as a proxy for precipitation and vegetation changes during the Devonian and Mississippian. All tetrapod bones and trackways in this region, as well as fossil tree remains, were found at times...

... rehabilitation provided an opportunity for researchers to observe and map a portion of the fossil forest ( Stein et al., 2012 ). The area was glaciated, and Glacial Lake Grand Gorge and Glacial Lake Schoharie occupied the Schoharie Valley during the Wisconsinan stage ( Rich, 1935 ; Titus, 2003 ). Core...

.... Fossils from this series have been collected at several localities and have been determined to be Carboniferous in age (2). At Floresta (Boyacá) is a soft shale whose abundant fossils, discovered by A. A. Olsson and Teófilo Ramirez in 1935, are believed by Kenneth E. Caster (3) to have a boreal aspect...

We assess the utility of morphologic characters in diagnoses of taxa, and present the first quantitative analysis of fossil hydroids to distinguish P. brevis n. sp.

This was later adopted as the de facto Silurian–Devonian boundary for this region (see review by D.A. Bassett, 1991 ). The LBB continued in this defining role until the formal...
