Tiering Style Analysis
Discussion
With reference to ichnofabric criteria (i.e, ichnofossil diversity, the number of ethology and tier, as in Figure 4 and Table 1), the tiering style responds as expected when (i) the kind of disturbances, (ii) colonization window and (iii) resistence and resilience are present with different degree in ancient deltaic depositional environment. Based on data obtained in this research, the several nature examples of tiering styles construction, as commented upon below.
Sedimentation Regime
The sedimentation regime in deltaic setting rule the disturbances that regulate the trace maker’s strategy to construct the tiering styles. The general decline of ichnofossil diversity and ethology may be driven by the higher regime of fluvial discharge during ichnofossil construction [see Arifullah, 2005]. When marine processes more dominant (e.g., wave) ichnofossil diversity and ethology are elevated [see Arifullah, 2005].
Disturbances
Ophiomorpha and Thallasinoides are taken as the examples of the 1st tiering style. Ophiomorpha is constructed by a suspension feeder [e.g., Seilacher, 1964] in the thixotropic …show more content…
First, Paleophycus, Ophiomorpha, and Cylindrichnus are constructed by a suspension feeder [e.g., Seilacher, 1964] in thixotropic substrate [see Bromley, 1996]. The increasing of ichnofossil in similar ethology suggests the strategy modification for food resources in suspension. Conversely, the other second group consist of Thallasinoides, Teichichnus, Planolites and Scolicia are constructed by deposit feeder and chemosymbiosis trace maker [e.g., Seilacher, 1964] that suggest the modification of feeding strategy in the nutrient-rich substrate. This fodonichnia community suggests cloudy water [cf., Rhoads and Young, 1970] and dilatancy substrate [see Bromley, 1996]. Beyond the time, the ethology is elevated to adapt the change of disturbances, consequently the 3rd tiering style is
