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.Carole J.

Modern contamination would seem to be of widespread occurrence on archaeological sites in Britain. It is particularly noticeable when recovery is increased by the use of a flotation machine. Sources of contamination and methods of distinguishing modern and ancient seeds are discussed. It should often be possible largely to discount the recent component providing that a certain amount of consideration is given to the problem in relation to a particular site, although there are still some areas requiring further research. 相似文献
