“…The soil was poorly drained and regularly exposed to subaerial conditions, indicated by the presence of redoximorphic features, such rhizohalos (Kraus & Hasiotis, 2006) and shrink-swell features, like the microfabric granostriated ( Figure 3F), in response to repetitive cycles of saturation and dryness (Lindbo et al, 2010). There is no evidence of preservation of organic matter in these deposits, indicating a relatively oxidative environment associated with the sub aerial exposure of these materials, at least seasonally (Retallack, 2001).…”

-The Marilia Formation (Bauru Group, Bauru Basin) is an important record of the Upper Cretaceous in Brazil, and hosts an important fossil content. However, works regarding continental ichnology in this unit are still scarce. In order to improve this knowledge, the present work describes the occurrence of Camborygma litonomos in paleosols developed from floodplain deposits of the Marilia Formation in the Minas Gerais State. This trace fossil is associated with the activity of freshwater crayfishes, digging the soil looking for protection and to avoid the carapace dryness. Crayfish body fossils have not yet been described in deposits of the Bauru Group, thus, the trace fossil here recorded is the exclusive evidence of this organism, which is of great importance to the knowledge of the invertebrates paleodiversity of the Marilia Formation during the Late Cretaceous.

“…The released Fe would form secondary oxides as Fe is largely immobile at the soil pH values recorded here (Jansen et al, 2003(Jansen et al, , 2005, whereas alkaline cations are highly mobile at these pHs (Martínez Cortizas et al, 2003;Chesworth et al, 2008). Repeated cycles of wetting and drying and the consequent development of redoximorphic features (Lindbo et al, 2010) are probably also contributing to this process. All these mechanisms may or may not occur concurrently and could affect the samples within the same section to varying degrees.…”

Agricultural landscapes are human-manipulated landscapes, most obviously in areas modified by terracing and/or irrigation. Examples from temperate, arid, and desert environments worldwide have attracted the attention of many disciplines, from archaeologists, palaeoecologists, and geomorphologists researching landscape histories to economists, agronomists, ecologists, and development planners studying sustainable resource management. This article combines these interdisciplinary interests by exploring the role archaeology can play in assessing sustainability. Our case study is Engaruka, Tanzania, archaeologically famous as the largest abandoned irrigated and terraced landscape in East Africa. The site has been cited as an example of economic and/or ecological collapse, and it has long been assumed to have been irrigated out of necessity because agriculture was presumed to be nearly impossible without irrigation in what is now a semiarid environment. Geoarchaeological research refutes this assumption, however, demonstrating that parts of the site flooded with sufficient regularity to allow the construction of more than 1000 ha of alluvial sediment traps, in places greater than 2 m deep. Soil micromorphology and geochemistry also record changes in irrigation, with some fields inundated to create paddylike soils. Geoarchaeological techniques can be applied to both extant and abandoned agricultural systems, thereby contributing to an understanding of their history, function, and sustainability.

“…According to Lindbo et al (2014), the biological oxidation of iron requires free oxygen, a source 476 of organic matter and iron and a temperature above 5°C. Other key factors for soil saturation and 477 iron redox reactions include retention time and soil depth (Lindbo, 2014).…”
