Unreviewed
Descriptive info From Wisshak et al., 2019: Trace fossil; type=macroboring; substrate=calcareous; tracemaker=invertebrate. [details]
Taxonomic remark Donovan & Pickerill, 2016 contend that Tremichnus is a junior synonym of Oichnus, however Bertling et al., 2022 maintain Tremichnus, stating: authors may wish to establish ichnotaxa based mainly on a particular substrate as an ichnotaxobase. An example is the bioerosion traces resulting from predation and parasitism, where recent producers are often restricted to a certain host clade or even species. In such cases, the substrate type should enter the diagnosis of respective ichnotaxa. In line with this reasoning, Wisshak et al. (2015) separated Tremichnus from Oichnus, in contrast to Pickerill & Donovan (1998), Zonneveld & Gingras (2014) and Donovan & Pickerill (2017). [details]
