Fig. 6: Examples of woody debris in the Pennant Formation, specifically in the Llynfi Member, at Kilvey Hill, Loc3.3.
From: Quantitative constraints on flood variability in the rock record
a The underside of the erosional base of a log-jam deposit in the conglomerate lithofacies, in which clasts comprise plant debris as opposed to rock fragments, overlying channel sandstone; b, c a closer view of this outcrop, with the largest woody debris fossils highlighted, noting that the matrix is composed of a mixture of sediment and macerated vegetation; d an example of well-preserved Lepidodendron fossils; e a debris bed in the sandstone lithofacies; f the cumulative frequency distribution of the minimum long axis of debris fossil found in the sandstone and conglomerate lithofacies; and g a schematic log displaying the typical features of the conglomerate and sandstone lithofacies in the Pennant Formation, using Kilvey Hill as an exemplar.
