NTA 6 progress report Anja Rösler, Departamento de Estra4gra6a y Paleontología Universidad de Granada Progress (1) • Coralline algal assamblages of many TF sta4ons characterized • 8 • Analysis of the samples of Batu pu4h region almost finished Progress (2) About 475 sequences of 5 gene4c markers of about 85 specimen of ±30 recent species obtained What else have I worked on since june? • ZMT Bremen • Amplifica4ons….coming to an end • New gene4c marker • Rhodolith workshop – First new ocurrance date established • Colabora4on in Stadium reef paper • Prepara4on EJIP Coralline algae from the Miocene Mahakam Delta (East Kalimantan, SE Asia) Anja Rösler and Juan Carlos Braga Universidad de Granada, Departamento de Estra4gra6a y Paleontología IV Interna4onal Rhodolith Workshop, Granada, 18.09.2012 Rhodolith beds associated with reefs Bed 2 Bed 1 Rhodolith beds associated with reefs Bed 2 Bed 1 Rhodolith beds associated with reefs Bed 1 rhodoliths: Main genera: Sporolithon (39%), Lithothamnion (23%), Mesophyllum(23%) and Lithoporella (10%) Rhodolith beds associated with reefs Bed 2 Bed 1 Rhodolith beds associated with reefs Bed 2 rhodoliths: mainly consis4ng of Lithothamnion (51%), Sporolithon (28%) and Mesophyllum (10%) Shallow reef Shallow reef Neogoniolithon ssp. (80%), Spongites and Lithoporella Shallow reef Neogoniolithon fosliei, new first occurrence date Was just known from Pleistocene to recent (Johnson 1965) Preliminary biostra4graphic analysis (with benthic forams) suggests a Serravallian age for this segng Summary • In darker water segngs: – Assemblages of Melobesioids and Sporolithon • In shallow water segngs: – Assemblages of “Mastophoroids” • First ocurrences of modern reef taxa in Miocene in SE Asia What else have I worked on since june? • ZMT Bremen • Amplifica4ons….coming to an end • New gene4c marker • Rhodolith workshop – First new ocurrance date established • Colabora4on in Stadium reef paper • Prepara4on EJIP What else have I worked on since june? • ZMT Bremen • Amplifica4ons….coming to an end • New gene4c marker • Rhodolith workshop – First new ocurrance date established • Colabora4on in Stadium reef paper • Prepara4on EJIP Next steps • • • • • • • • Finishing of gene4c laboratory work in ± one week Obtain evolu4onary and phylogen4c informa4on from results Further study of fossil samples to be finished this year, too Establish more “new” first ocurrences of coralline species Prepara4on EJIP GSA annual mee4ng in Charlole Work on first own publica4ons (february) SAGE conference in Berlin (march) Thanks!
