Genus

Apectoichnus Donovan, 2018

Taxon description

Mayoral et al., 2020

Revised diagnosis: Apectoichnus predominantly parallel to the grain or fibres in a xylic substrate, length/width ratio greater than 5. Sinuous to contort.

Melnyk et al., 2020 (for 2021)

Emended diagnosis.—Elongate borings in xylic substrata and associated resins, nearly circular in cross section, with an approximately constant diameter. Borings are straight to sinuous or contorted and intertwined and predominantly occur parallel to the fibers of xylic substrata (modified from Donovan, 2018; Mayoral et al., 2020).

Wisshak et al., 2019a

Macroboring; substrate xylic; tracemaker invertebrate
