1. The Cambrian lophotrochozoans of the Transantarctic Mountains, Antarctica
Sammanfattning : The origin of many lophotrochozoan groups can be traced to “small shelly fossil” (SSF) faunas of the Early Cambrian. Antarctica is a key region of study, due to the continent’s known close geographical proximity to well-studied Australian and Indian basins in in the Cambrian. LÄS MER
2. Cambrian Series 2 (Stages 3-4) Small Shelly Fossils from East Antarctica
Sammanfattning : An assemblage of Cambrian Series 2, Stages 3-4 small shelly fossils has been recovered from the Shackleton Limestone and Holyoake Formations of East Antarctica. Small shelly fossils from the early Cambrian are an important window into the world of Cambrian palaeobiology, biostratigraphy and biogeography. LÄS MER
3. Biostratigraphy and Systematics of Cambrian Small Shelly Fossils from East Antarctica and South Australia
Sammanfattning : The remote lower Cambrian Byrd group of sedimentary rocks from East Antarctica has been studied intermittently since its discovery over a century ago. Previous insights into the trilobites and archaeocyaths indicated a close correlation to the sedimentary sequences of South Australia. LÄS MER
4. Early Cambrian Problematic Lophotrochozoans and Dilemmas of Scleritome Reconstructions
Sammanfattning : The emergence and radiation of metazoan body plans around the Precambrian/Cambrian boundary, some 500-600 million years ago, seems to be concordant with the appearance and diversification of preservable hard parts. Several Precambrian soft-bodied, multicellular organisms most likely represent stem-group bilaterians, but their fossil record is rather sparse. LÄS MER
