Diplichnites

From Wikipedia, the free encyclopedia

Diplichnites is an ichnogenus thought to be made by members of the Arthropoda family. It is a fossil trackway, showing two parallel lines of feet impressions. The famous terrestrial arthropod genus Arthropleura produces the trace fossil D. cuithensis. Diplicnites is traditionally thought to be a trilobite trace fossil; however it is also produced by other organisms, such as freshwater & terrestrial arthropods (of unknown affinity, but possibly myriapods).^[1]

[edit] Trilobite ichnotaxa: stationary to full stride

Three ichnotaxa describe the trilobite motion from: the rest-position, walking, to full-stride, and also the reverse:

Rusophycus, walking–Cruziana, Diplichnites

and the reverse coming to the "rest-position":

Diplichnites, walking–Cruziana, Rusophycus (see article here: [1])

For the trilobites, gradations between the three ichnotaxa are common, and therefore can be confusing, or harder to categorize.
