| In marine sediments marine phytoplankton are widely used in biostratigraphy. |
| These chapters are required reading for anyone interested in how rigorous biostratigraphy should be done with any fossil group, not just mammals. |
| The San Juan Member is late Oligocene based upon biostratigraphy and radiometric dating. |
| Since the presence of these cells would be tied directly to important geochemical events, they would make ideal organisms for biostratigraphy. |
| The research integrates seismic interpretation, sedimentology and biostratigraphy from previously collected seismic data and piston cores. |
| Strong uniformity in Permian ammonoid biostratigraphy and provincialism between Xinjiang and Pamir is suggested. |
