Lacking in lithotype 4a, the occurrence of Thallassinoides and Planolites burrows in lithotype 4b suggests periods of relative decrease in sedimentation rate during time of deposition and the onset of seafloor lithification (Ekdale and Bromley, 1991). 4.1.5. Lithotype 5: silica- and clay-rich wackestone to packstone1. Introduction. Storm-generated beds in a shelf siliciclastic setting have been widely studied since the first recognition of hummocky cross-stratification (Harms et al., 1975).The ichnologic signatures in this depositional system also received attention, mostly aiming to understand how storm waves affected the infauna and the resulting trace …

The intensely bioturbated parts have a mottled texture and additionally present Palaeophycus as upper and Zoophycos as deep tier.The upper section is dominated by a relatively diverse trace fossil assemblage, composed of Asterosoma, Anconichnus, Chondrites, Planolites, Siphonichnus, Thalassinoides and Teichichnus, which in combination constitute the Cruziana ichnofacies (MacEachern and Bann, 2008). No complex overprinting of trace fossil assemblages is observed.

However, the restriction on microbial growth was reduced in lower-offshore / shelf or tidal-flat and back-barrier settings, where Chondrites-Planolites (ChPl) and Planolites (Pl) ichnofabrics dominate. This restricted microbial growth resulted from physico-chemical stresses on infaunal communities, as shown by the low ichnodiversity ...Planolites, together with mottled burrows (Figure 5A) are present at certain depths while there is no indication of trace fossil activity at other intervals.Five species, namely, Planolites annularis, P. beverleyensis, Rosselia socialis, Thalassinoides paradoxicus and T.

Fossils of Ohio (1996): Planolites is a more or less horizontal, straight to curved burrow that does not have any apparent lining. It can be confused with Paleophycus, another horizontal to subhorizontal burrow, which does have a distinct lining. Planolites is rarely branched. Specimens of Planolites, a tubular ichnofossil, from the Harkless Formation (Cambrian of Nevada) are commonly rimmed by thin layers of limonite, a probable pseudomorph after pyrite, suggesting that bacterially induced biomineralization played a key role in the preservation of the burrows.Organic material secreted by a vermiform, infaunal tracemaker is inferred to have formed the substrate for ...I went to the local outcrop in my hometown and found this matrix.
