Trichophycus pedum
Treptichnus is a genus of trace fossils (with modern analogues) representing a three-dimensional burrow. These fossil traces are known from marine, brackish, and freshwater deposits from the Ediacaran (550 million years ago) to the Upper Oligocene (24 mya).
Paleodictyon
Paleodictyon is a trace fossil, usually interpreted to be a burrow, which appears in the geologic marine record beginning in the Precambrian/Early Cambrian and in modern ocean environments. Paleodictyon were first described by Giuseppe Meneghini in 1850. The origin of the trace fossil is enigmatic and numerous candidates have been proposed.
paleoburrow
A paleoburrow is an underground shelter excavated by extinct paleo-vertebrate megafauna that lived in the prehistoric era. Most paleoburrows are likely made by giant armadillos, pampatheres, and/or large ground sloths, depending on their size.'''''' Thousands of examples have been identified across South America, mostly in the Brazilian states of Santa Catarina and Rio Grande do Sul.
