Stephanostomum tantabiddii n. sp. (Digenea: Acanthocolpidae) from Carangoides fulvoguttatus (Forsskal, 1775) (Perciformes: Carangidae) from Ningaloo Reef, Western Australia

A new species, Stephanostomum tantabiddii n. sp., is described from the yellowspotted trevally Carangoides fulvoguttatus from Ningaloo Reef, Western Australia. It has 38 - 45 circum-oral spines and the vitellarium reaches to no less than 17% of the hindbody length from the ventral sucker. It differs from other species of Stephanostomum with these characteristics by various combinations of the ventral hiatus of the circum-oral spine rows, the relatively long pars prostatica and short ejaculatory duct, the elongate body and the wide gaps between the gonads.

AMS dating of rock art in the Laura Region, Cape York Peninsula, Australia - protocols and results of recent research

The authors describe rock art dating research in Australia using the oxalate method While the array of dates obtained (which range from c. 1200 to c. 25000 BP) show a satisfactory correlation with other archaeological data, there are mismatches which suggest that some motifs were often imitated by later artists, and/or that the mineral accretions continued to form periodically, perhaps continuously, as a regional phenomenon over a long period of time.
