Actualistic studies of the distribution, formation, and taphonomy of vertebrate and invertebrate traces at saline (60-100 g l -1 TDS), alkaline (pH: 10.5) Lake Bogoria in the Kenya Rift Valley have revealed a diverse trace assemblage in the lake-margin sediments. Although hypersaline lakes like Lake Bogoria restrict lacustrine faunal diversity, local marginal subenvironments, including hot springs and ephemeral streams, provide favorable areas for the activities of many species of insects, mammals, birds, and reptiles. Several factors, including sediment texture and moisture content, substrate cohesion, substrate consolidation, and the presence of a food source (i.e., vegetation, microbes, animal waste, flamingo carcasses), control the distribution of traces at Lake Bogoria by influencing the behavior of vertebrates (e.g., "dirt bathing" and nest building) and invertebrates (mainly feeding and locomotion). The distribution of vertebrate traces is also controlled by the proximity to fresh water, but the relationship between invertebrate trace formation and porewater salinity is less clear.Many characteristic features of closed-basin lakes, including frequent changes in lake level and shoreline position, the presence of thermal springs, and evolved fluid compositions resulting from evaporation, can have direct impacts on trace taphonomy. Notable taphonomic factors include efflorescent salt crystallization, which may temporarily cement substrates or destroy traces during crystal growth in the capillary fringe; substrate wetting and drying, which can induce soil crusting and the shrinking and swelling of smectitic clays, which in turn can modify trace morphology; and the presence of benthic microbial mats and biofilms, which can temporarily stabilize substrates or contribute to their early cementation by mediating carbonate precipitation. Semiarid environments, such as the Kenya Rift, are favorable settings for the early cementation of substrates by carbonates (e.g., calcite), and, during prolonged, stable dry phases, the preservation of trace fossils and their substrates by zeolites and other minerals (Mn-and Fe-oxyhydroxides).

“…Two other network ichnogenera have been described from continental deposits. These are Vagorichnus described by Buatois et al (1995) from Jurassic lacustrine turbidites of subsequently retained as a valid ichnotaxon by Uchman et al (2007). As in Multina, Vagorichnus is a feeding structure involving active fill.…”

“…As in Multina, Vagorichnus is a feeding structure involving active fill. However, in contrast to Multina, Vagorichnus is characterized by a wider morphologic variability, a complex branching pattern (including also secondary successive branching), and abundant aligned knobs that indicate vertical meandering movements (Buatois et al, 1995). Labyrintichnus is morphologically very similar to Multina but it is passively filled (Uchman and Á lvaro).…”

An early Cambrian ichnofauna consisting of Helminthoidichnites tenuis, Helminthopsis tenuis, Multina isp., Oldhamia alata, and Pilichnus cf. dichotomus is documented from shallow-marine deposits ranging from the upper offshore to the offshore transition in the Puncoviscana Formation of northwest Argentina. Although the ichnogenus Oldhamia is more common in Cambrian deep-marine environments, this occurrence provides further evidence that it is also present in shallow-marine environments. The burrow network Multina (senior synonym of Olenichnus) is preserved at the base of tempestites, representing the activity of post-storm colonizers. A drowning surface separating offshore-transition deposits below from upper-offshore deposits above contains widespread evidence of trace fossils in direct association with matgrounds. The undermat miners Oldhamia alata and Pilichnus cf. P. dichotomus occur on this surface, revealing exploitation of organic matter in the biomat. Low sediment rate during drowning and paucity of bioturbation by sediment bulldozers may have promoted the establishment of the matground. In comparison with the simpler animal-matground interactions characteristic of the Ediacaran, the combination of Cambrian evolutionary innovations and the presence of microbial mats promoted more sophisticated interactions. Complex feeding trace fossils revealing that systematic undermat mining, as displayed by Oldamia alata and Pilichnus cf. dichotomus, is a product of the Cambrian explosion.

“…Three-dimensional burrow systems as described above are commonly referred to the ichnogenus Vagorichnus (Buatois et al, 1995). Morphological similar burrows were described from Triassic lake deposits of Kyrgyzstan and attributed to the activity of oligochaetes or aquatic insect larvae (Voigt and Hoppe, 2010).…”

Trace fossils and palynomorphs are recorded for the first time in Holocene calcareous concretions from Lake Selbusjøen, Central Norway. The described trace fossils can be assigned to the Mermia ichnofacies, characterizing lake deposits with good oxygenation and low depositional energy. The predominance of simple grazing trails and shallow burrows (e.g. Cochlichnus, Helminthoidichnites and Treptichnus) in silty and sandy concretions possibly represent relatively low-energy sublittoral parts of the lake, while the occurrence of Vagorichnus and Arenicolites in sandy substrate points to littoral and shallow sublittoral areas with moderate depositional energy. The trace fossils and palynomorph assemblages from Lake Selbusjøen appear to relate to periods of climatic warming during Pre-Boreal times, and possibly also Atlantic times.
