Fire in the thatch : a Devon mystery
\"The Second World War is drawing to a close. Nicholas Vaughan, released from the army after an accident, takes refuge in Devon--renting a thatched cottage in the beautiful countryside at Mallory Fitzjohn. Vaughan sets to work farming the land, rearing geese and renovating the cottage. Hard work and rural peace seem to make this a happy bachelor life. On a nearby farm lives the bored, flirtatious June St Cyres, an exile from London while her husband is a Japanese POW. June's presence attracts fashionable visitors of dubious character, and threatens to spoil Vaughan's prized seclusion. When Little Thatch is destroyed in a blaze, all Vaughan's work goes up in smoke--and Inspector Macdonald is drafted in to uncover a motive for murder\"--Provided by publisher.

Combined sea-level and climate controls on limestone formation, hiatuses and ammonite preservation in the Blue Lias Formation, South Britain (uppermost Triassic – Lower Jurassic)
Lithostratigraphic and magnetic-susceptibility logs for four sections in the Blue Lias Formation are combined with a re-assessment of the ammonite biostratigraphy. A Shaw plot correlating the West Somerset coast with the Devon/Dorset coast at Lyme Regis, based on 63 common biohorizon picks, together with field evidence, demonstrate that intra-formational hiatuses are common. Compared to laminated shale deposition, the climate associated with light marl is interpreted as both drier and stormier. Storm-related non-deposition favoured initiation of limestone formation near the sediment–water interface. Areas and time intervals with reduced water depths had lower net accumulation rates and developed a greater proportion of limestone. Many homogeneous limestone beds have no ammonites preserved, whereas others contain abundant fossils. Non-deposition encouraged shallow sub-sea-floor cementation which, if occurring after aragonite dissolution, generated limestones lacking ammonites. Abundant ammonite preservation in limestones required both rapid burial by light marl during storms as well as later storm-related non-deposition and near-surface carbonate cementation that occurred prior to aragonite dissolution. The limestones are dominated by a mixture of early framework-supporting cement that minimized compaction of fossils, plus a later micrograde cement infill. At Lyme Regis, the relatively low net accumulation rate ensured that final cementation of the limestones took place at relatively shallow burial depths. On the West Somerset coast, however, much higher accumulation rates led to deeper burial before final limestone cementation. Consequently, the oxygen-isotope ratios of the limestones on the West Somerset coast, recording precipitation of the later diagenetic calcite at higher temperatures, are lower than those at Lyme Regis.

A new species of Hyattechinus (Echinoidea) from the type Devonian of the United Kingdom and implications for the distribution of Devonian proterocidarid echinoids
Many of the most diverse clades of Late Palaeozoic echinoids (sea urchins) originated in the Devonian period. Our understanding of diversity dynamics of these Late Palaeozoic clades are thus informed by new systematic descriptions of some of their earliest members. The Proterocidaridae are a diverse and morphologically distinct clade of stem group echinoids with flattened tests and enlarged adoral pore pairs, which are first known from the Upper Devonian. We herein report on a new species of Hyattechinus, Hyattechinus anglicus n. sp., from the Upper Devonian of the North Devon Basin, Devon, UK. This is the first Devonian Hyattechinus known from outside of the Appalachian Basin, USA, and provides novel information regarding the palaeogeographic and stratigraphic distribution of proterocidarids in Late Devonian times. We additionally update the stratigraphic distribution of Devonian Hyattechinus from the Appalachian Basin, following recent biostratigraphic resolution of their occurrences. Hyattechinus appears to have been present in the Rheic echinoderm fauna during Late Devonian times, and comparison of the palaeoenvironmental setting of Hyattechinus anglicus with that of other Hyattechinus from the Famennian of the Appalachian Basin suggests that the genus may have preferred siliciclastic settings. Furthermore, this new taxon increases the diversity of echinoids from the Upper Devonian of Devon to three species.

Spring : the story of a season
Michael Morpurgo has lived on a farm deep in rural Devon for more than forty years. In 'Spring', he observes the season unfold around him, as fragile new shoots emerge, buds turn to blossom and grey skies give way to blue. As the natural world shakes off a long winter, Michael watches lambs being born on the farm, delights in a fanfare of bluebells in the woods, and sings to the birds, dressed in his wellies and dressing gown. He shares small moments of joy found in the back garden, as well as more dramatic encounters with sparrowhawks, hares and otters. With new poems and reminiscences about childhood and springs gone by, this is an enchanting celebration of the season from one of the world's best-loved authors.

Improved models for estimating soil erosion rates from cesium-137 measurements
Fallout cesium-137 (137Cs) measurements have been used in investigations of water-induced soil erosion in a wide range of environments and in many different areas of the world over the past 20 yr. However, the existing calibration procedures commonly used for deriving quantitative estimates of soil redistribution rates from 137Cs measurements involve several limitations and uncertainties. Existing approaches to calibration and their associated limitations and uncertainties are briefly reviewed and improved models for converting 137Cs measurements to estimates of rates of water- and tillage-induced soil redistribution, applicable to both cultivated and undisturbed soils, are proposed. Results obtained from existing field investigations and laboratory experiments indicate that redistribution of fallout 137Cs within the soil profile and across the land surface is influenced by several factors. These include time-dependent fallout input, initial distribution within the surface layer, post-depositional redistribution resulting from mechanical, physical, chemical, and biological processes operating in the soil system and the grain size selectivity associated with soil erosion and sediment transport processes. It is important to consider these factors when deriving estimates of soil redistribution rates using the 137Cs technique, and they have been incorporated into the improved models. The use of these models is demonstrated using data from a case study undertaken in a small catchment in Devon, UK, involving both cultivated and undisturbed soils.

Sea-level change and facies development across potential Triassic-Jurassic boundary horizons, SW Britain
The Late Triassic to Early Jurassic aged succession of SW Britain (the Penarth and lower Lias Groups) comprises mudstone, sandstone and limestone strata deposited in a variety of marine to non-marine environments. Faunal and floral characteristics of these successions have led to the proposal that one location in SW England, St Audrie's Bay, should serve as the Global Stratotype Section and Point (GSSP) for the base of the Hettangian Stage and, thus, for the Triassic-Jurassic (Tr-J) boundary. The sections of SW Britain have also been used previously to infer sea-level change history and relate this to potential kill mechanisms associated with the Tr-J boundary mass extinction. Chemostratigraphic, biofacies and lithofacies data are used here to suggest alternative models of sea-level change in relation to possible Tr-J boundary horizons in the sections of SW Britain. A sea-level lowstand surface of erosion is inferred to occur within the Cotham Member of the Lilstock Formation, a unit deposited in an environment that was often subaerially exposed. In contrast to previous interpretations, the top surface of the overlying Langport Member (here inferred to be deposited on a carbonate ramp of depositional or tectonic origin) represents a drowning event of at least regional extent. All horizons regarded as plausible levels at which to place the Tr-J boundary based on fossil distributions lie within strata deposited during relative sea-level rise. However, it is doubtful whether the higher horizons proposed to mark the boundary faithfully record times of true biotic change on a global scale and, additionally, there is no positive evidence that sea-level fall had any relation to the genesis of proposed Tr-J marker horizons. It is unlikely that sea-level fall played a significant role in the Tr-J boundary extinctions in either a local or a global context.
