Size of fossils: | microfossils |
Collection methods and comments
Collection methods: | core,chemical,sieve,field collection |
Minimum sieve size: | 0.037 |
Reason for describing collection: | taxonomic analysis |
Collection method comments: The Azollopsis pusilla specimen was named specimen number S357 in the slide information area, but S351 in the locality description area. The locality description matched that of S351, so I have put it in the S351 collection. The specimens figured in the paper have slide and collection number information. They also have more detailed locality information. Azollopsis intermedia: AS-S351-C-3-1, GSC 30862. Azollopsis pusilla: AS-S351-S-0-14, GSC 30881. |
