ichthyosaur
Danh từ
Số nhiều: ichthyosaurs
This term is primarily used within the specialized registers of paleontology and evolutionary biology. It describes a specific group of extinct reptiles, and while it is often compared to dolphins due to convergent evolution, it is crucial to distinguish them as reptiles rather than mammals in a scientific context.
Because it refers to a specific biological taxon, the word is used as a standard countable noun. It typically appears in academic texts, museum catalogs, or educational materials discussing the Triassic and Jurassic periods.
