Their scientific name is from Greek bregma meaning the top of the head, and keras meaning "horn"; this refers to their occipital ray (a spine emerging from the top of the head).
Fossils of Bregmaceros are found from the Eocene to the Quaternary (age range: from 37.2 to 0.0 million years ago.). They are known from various localities in Europe, North America and South America.[2]
A potential extinct relative, Bregmacerina, is known from the Early Miocene of Russia, where it inhabited the Paratethys. It shares close similarities to Bregmaceros in the reduction of the first dorsal fin, but differs in other aspects. It remains uncertain whether it is an actual member of the Bregmacerotidae.[3]
Currently, 17 species in this genus are recognized:[4]
