The museum bears the name of Hasan bey Zardabi, an Azerbaijani journalist and intellectual, and founder of the first Azeri-language newspaper Akinchi ("The Ploughman") in 1875.
The biological department exhibits numerous skeletons and fragments of animal bones found during field work and treated by researchers.
Among those are near-complete fossilized skeletons of horses, deer, gazelles and saigas that don't live in the territory of Azerbaijan anymore.
In addition, the museum also has two types of hipparions (mammals of the horse family), the Sarmatian whale and the lower jaw of a mastodon.
The museum also exhibits the upper jaw, teeth and tusks of the southern elephant which lived in the country, 600000 years ago and was discovered in Mingachevir in 2001.
