Burrow, C.J., Turner, S., Trinajstic, K. & Young, G.C., 27 February 2019. Late Silurian vertebrate microfossils from the Carnarvon Basin, Western Australia. Alcheringa 43, 204–219. ISSN 0311-5518.
A core sample from the offshore Pendock 1A well, Carnarvon Basin, Western Australia yielded microvertebrate residues at an horizon in the lower part of the Hamelin Formation, dated as late Silurian, ? Ludlow, based on associated conodonts. The fish fauna comprises loganelliiform thelodont scales, the ? stem gnathostome Aberrosquama occidens nov. gen. et sp., the acanthodian Nostolepis sp. aff. N. alta, and the ? stem osteichthyan Andreolepis sp. aff. A. petri. Because of the paucity of the material, and some differences between the Pendock scales and those of established species, a precise age can not be confirmed; however, the composition of the fauna at generic level most closely resembles that of late Silurian (Ludlow) assemblages from northern Eurasia.
