WebJan 1, 2013 · Graphoglyptid burrows lend themselves to fractal geometric analysis, because they commonly exhibit the essential fractal characteristics of scale invariance … WebSixteen fan and related environments are recognized from upper-slope gully to the distal basin-floor. For each environment, the degree of bioturbation (density), trace-fossil diversity, number of pre-depositional and post-depositional trace fossils, as well as the number of graphoglyptid ichnospecies were quantified.

WebFor this study s purposes, the graphoglyptid trace fossils were grouped into four different topological categories: meandering forms, spiraling forms, branching forms, and network forms(Fig.1;alsoseeLehaneandEkdale2014). Each trace fossil was analyzed and compared with all of the other trace fossils within each of the four topological groups. WebEkdale AA, Lewis DW.
