| In dating these events, detailed correlation and detailed biostratigraphy is essential. |
| Since the presence of these cells would be tied directly to important geochemical events, they would make ideal organisms for biostratigraphy. |
| The San Juan Member is late Oligocene based upon biostratigraphy and radiometric dating. |
| Strong uniformity in Permian ammonoid biostratigraphy and provincialism between Xinjiang and Pamir is suggested. |
| The papers that follow concentrate on the integration of high-resolution geochemical records with detailed biostratigraphy. |
| Keith Young published over 100 papers and contributed to numerous symposia and field guides dealing with Mesozoic biostratigraphy. |
