The name and its history
No verified first naming act · Earliest geological use not securely page-verified
- What does the word literally mean?
- Immediate source or formation: Borrowed from Spanish coquina, ‘cockle’ or small shell, ultimately Latin concha. Literal gloss ‘little shell / cockle stone’. This linguistic evidence is distinct from claims about the namer’s intentions.
- What did the original author mean?
- Spanish communities and colonial builders knew the shelly stone of Florida as quarry material; that historical utility should not be mistaken for a verified moment of scientific coinage.
- Why was the name needed?
- A name was needed for conspicuously shell-rich stone whose texture and durability differed from compact limestones.
- What evidence supported the original concept?
- Abundant recognisable broken shells and carbonate cement; historic building records document usage, not necessarily its first geological description.
- How has geology changed the concept?
- Coquina can be described more precisely with grain-support, cement and bioclast content; its environment cannot be deduced merely from a shell-rich appearance.

Editorial qualification
Priority and exact original naming language not independently authenticated; distinguish documented later use from first coinage.
