Definition

Usage

• The term Ceratodontidae is used almost exclusively in scientific and zoological contexts to classify a specific taxonomic group of lungfishes.
• It is a proper noun and is typically capitalized.

Examples

• Noun:
  • The fossil record shows that the Ceratodontidae were once more widely distributed.
  • Biologists study the Ceratodontidae to understand the evolution of air-breathing in vertebrates.

Advanced Usage

• In taxonomic hierarchy, Ceratodontidae sits at the family level. Related terms include:
