Graphoglyptid
WebTopological analysis of graphoglyptid trace fossils, a study of macrobenthic solitary and collective animal behaviors in the deep-sea environment 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.
