“…Regrettably, papers that analyse trace fossils and palaeosols with such a degree of detail are too few to provide a broad reference database (e.g. Bown & Kraus 1983;Hasiotis & Dubiel 1994;RetaUack 2001b;Genise et al 2002). A second evaluation of palaeoenvironmental changes involves the recognition of the producers of ichnotaxa recorded from palaeosols.…”

“…Two main facies type are recognized where the unit reaches its maximum thickness . Pyroclastic facies predominate, including massive sheet strata of vitric-crystal tufts, very fine tufts with accretionary lapilli, and bioturbated tuffaceous mudstones and claystones (Sciutto 1981;Genise et al 2002). The remaining facies are fining-upward cross-bedded pyroclastic sandstones and scarce intra-formational conglomerates, which are subordinate, albeit significant, because they are mostly restricted to incised channels.…”

Studies on ichnofabrics have focused mainly on marine environments. Attempts to apply the ichnofabric methodology and theoretical framework to continental deposits bearing palaeosols are few and poorly developed. Methodologies analysed in this contribution include the applicability of current ichnofabric indexes and diagrams, the assessment of the destruction of the original bedding by ichnofabrics and by other soil characters separately, and the relationships between different stages of palaeosol and ichnofabric development. Many soil features may be formed without the intervention of bioturbation, or may be the result of interactions of physical, chemical and biological processes, in which traces of organisms may have only a subsidiary role. Ichnofabrics can be well developed in palaeosols devoid of other soil characters and, conversely, palaeosols showing a well-developed soil structure can bear almost no trace fossils. This fact adds a third component to classical methods that normally consider only original bedding and ichnofabrics. Theoretical analysis includes the possibility of recording composite ichnofabrics in palaeosols, and the value of individual ichnotaxa as possible indicators of subaerial conditions and environmental changes. The ecological preferences and requirements of trace-makers provide the key to understanding composite ichnofabrics; however, only complex traces can be certainly attributed to particular modern taxa. Insect nests, pupal chambers and earthworm burrows are the most reliable indicators of subaerial exposure and, in many cases, very particular environmental conditions.

“…The assignation of Rebu f foichnus to Curculionidae and Scarabaeidae (Coleoptera) was extensively discussed by ]ohnston et al (1996) under the name of Fictovichnus, and by Genise et al (2002b), who provided comparisons with extant coleopteran pupation chambers. Particularly, in support of this hypothesis, was the record of an adult weevil illustrated by Lea (1925, plate J) in a specimen of Rebu f foichnus casamiquelai from the Quaternary limestones of Australia.…”

“…Trace fossils are typically the only means of evaluating biodiversity in ancient terrestrial deposits, particularly in paleosols, where the preservation potential of body fossils is typically low but organism abundance can be high (e.g., Retallack, 1984;Genise et al, 2000Genise et al, , 2002Hasiotis et al, 2003;Hasiotis, 2004Hasiotis, , 2007Hasiotis, 2007a, 2008;Hembree and Nadon, 2011). Trace fossils are generally easily preserved even in environments where body fossils are rare; therefore, the use of both body and trace fossils are necessary to provide the best paleoecological interpretations (e.g., H€ antzschel, 1975;Osgood, 1975;Frey, 1978;Bromley, 1996;Pemberton et al, 2001;Hasiotis, 2007).…”

The successful interpretation of continental ichnofossils is impeded by our limited knowledge of the burrows produced by modern continental animals. Actualistic studies of modern burrowing animals provide the data that make trace fossils invaluable to paleoecological and paleoenvironmental reconstructions. The goal of this project is to determine how well burrows produced by terrestrial arthropods, amphibians, and reptiles engaged in known behaviors under controlled environmental conditions can be differentiated on the basis of qualitative and quantitative morphology. The animals produced a diverse assemblage of shafts, tunnels, ramps, U-, J-, W-, Y-shaped and helical burrows, and mazeworks. The quantitative aspects of the burrow morphologies were compared using nonparametric similarity and distance indices as well as cluster analyses to determine if the burrow casts could be effectively differentiated based upon their tracemakers, behaviors, and environmental conditions. By using multiple properties of burrow morphology to compare the burrows statistically, many of the burrows were separated according to different behaviors and tracemakers, although overlaps did occur. Levels of similarity were highest amongst animals with similar morphologies, burrowing techniques, and behavioral patterns. Results from these analyses provide an assessment of our ability to reconstruct ancient soil ecosystems based on trace fossil morphology. By assembling a comprehensive analysis of the burrows of modern terrestrial animals, trace fossils may be described in a similar manner and compared directly to these modern analogs. This will be invaluable to improving the interpretation of tracemakers and behaviors.
