The name and its history

- What does the word literally mean?
- Named for the ‘lotus state’. Immediate scientific language-route: Chinese Furong (芙蓉, ‘lotus’) → international English. This is a locality-based or geographical term, not a description of a universal geological event.
- What did the original author mean?
- The uppermost globally recognised Cambrian series, beginning at the Paibian boundary in the Chinese Huaqiao succession.
- Why was the name needed?
- A distinctive internationally recognisable upper Cambrian series was named after a poetic nickname of the Chinese province containing its basal boundary stratotype. This is a rare case where the underlying word is itself transparently descriptive but not of geology.
- What evidence supported the original concept?
- The basal Paibian boundary at Paibi was correlated using first appearance of the agnostoid Glyptagnostus reticulatus.
- How has geology changed the concept?
- Replaced an unnamed upper Cambrian series; the lotus reference is geographical and cultural, not a claim that these Cambrian seas contained lotuses.
Further historical context
*Naming and context.* A distinctive internationally recognisable upper Cambrian series was named after a poetic nickname of the Chinese province containing its basal boundary stratotype. This is a rare case where the underlying word is itself transparently descriptive but not of geology.
*Evidence and later scope. The basal Paibian boundary at Paibi was correlated using first appearance of the agnostoid Glyptagnostus reticulatus*. Replaced an unnamed upper Cambrian series; the lotus reference is geographical and cultural, not a claim that these Cambrian seas contained lotuses.
Editorial qualification
Translate the Chinese word, but do not infer a floral or palaeoenvironmental character for the rocks.
