Nutrition And Ageing In Africa, Karen E. Charlton Jan 1999

Systematics, Biostratigraphy And Evolution Of The Late Ludlow And Pridoli (Late Silurian) Graptolites Of The Yass District, New South Wales, Australia, R B. Rickards, Anthony J. Wright

Faculty of Science, Medicine and Health - Papers: part A

Graptolites from the Yass district of New South Wales include important material from: low in the Black Bog Shale; from the Yarwood Siltstone Member; 2 levels high in the Black Bog Shale; 2 levels low in the Rosebank Shale; low in the Cowridge Siltstone; and in the lower part of the Elmside Formation. The faunas from the lower 4 levels are late Ludlow (early Late Silurian), and the higher 4 levels are Prídolí (late Late Silurian). Twenty-seven graptolite taxa, a considerable increase on previous records from Yass, have been identified in the late Ludlow and Prídolí of the district. These ...
