Zeltornis is an extinct genus
of heron
. It contains a single species, Zeltornis ginsburgi.
Zeltornis probably resembled the modern night heron
s, but was much larger, standing 2 m (6 ft 8 in) tall and weighing about 15 kg. Its wingspan is estimated at 2.50 m (8 ft 4 in). It is known from a single right coracoid of which the distal part is missing (MNHN collection, uncatalogued). Nonetheless, the partial bone is distinctive enough to place the species clearly into the heron family
. In particular it seems to have been allied most closely to the night herons, although it cannot have been a direct ancestor of extant species because the modern genus Nycticorax
did already exist in the Oligocene
.
Zeltornis is named after the mountain
Zelten in Libya
, where it was found.

Zeltornis probably resembled the modern night heron
Night heron
The night herons are medium-sized herons in the genera Nycticorax, Nyctanassa and Gorsachius. The genus name Nycticorax derives from the Greek for “night raven” and refers to the largely nocturnal feeding habits of this group of birds, and the croaking crow-like call of the best known species, the...

Family (biology)
In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...
