On the Swine Limestone |
| |
| Abstract: | The name Swine Limestone was proposed by J. 8. Lee for a thick sequence of limestones near Chuanshau of Zhenjiang. It measures about 13 metres in thickness, and is overlain by the Misellina claudiae zone of the Chihsia Formation and is underlain by the Sphaeroschwagerina moellcri zone of the Chuanshan Formation. Darvasites ordinatus of the Swine Limestone has been regarded by Li and Zhang (1982) as a zone fossil. The Swine Limestone belongs to the lowermost part of the Lower Permian. |
