Supporting data from paper: Hill et al. 2019 Evolution of jaw disparity in fishes. Palaeontology 61: 847-854. The data consists of two files: (1) an Excel spreadsheet listing the taxa used in the study, specimen number, clade, age; (2) a Word document outlining the data collection and analysis procedure used in the study.

This dataset contains the collated wireline logs, stratigraphy and core analysis of the three boreholes drill as part of the publicly funded Rapid Global Geological Events Project (RGGE) which ran between 1995-1998. The aim of the RGGE project was to identify the effects of climatic changes on modern sediments. The project focused on the Kimmeridge Clay due to its unbroken sequence of fossiliferous marine mudstones. These mudstones have compositional variations in organic content, minerology, fauna and clay content which reflect changes in both the climate and sea level. Over the course of the project the entire sequence of the Kimmeridge Clay was cored across three boreholes, two at Swanworth Quarry and one at Metherhills.
