Order (biology)

The order (Latin ordo) is a basic taxonomic category - a unit of hierarchical classification of organisms, formed by families (lat. Familia). One or more related orders form a class (lat. Classis). Systematic botany and mycology traditionally use the same stable endings -ales for taxonomic units at the order level. Its Czech equivalent is the suffix -tvaré. E.g. Ericales or Boletales. In zoology, the situation is somewhat different - usually the original (often used) names without a special ending are used here, such as the order Carnivora (beasts).

Nadřád

Superorder (Latin Superordo) is a taxonomic category higher than order but lower than class. Examples are dinosaurs (Dinosauria), a popular group of vertebrates, which also includes modern birds, or a large group of placentals, which includes most living mammals or a group of bony fishes.
