Giants of the Mesozoic, on display in the atrium of Fernbank Museum, features a 123-foot (37 m) long Argentinosaurus, the largest dinosaur ever classified; as well as a Giganotosaurus.

In the late 1800s, a nature-lover named Emily Harrison grew up in an area east of Atlanta which she called "Fernbank".

[4] Following master planning and designs by the Cambridge, Massachusetts-based architectural firm, Graham Gund Architects, ground was broken in 1989, and on October 5, 1992, Fernbank Museum of Natural History opened to the public.

The new building is carefully located behind a row of historic houses, and features a glass-enclosed atrium overlooking Fernbank Forest.

Formerly an IMAX theater, upgrades were completed in February 2017 including a digital 4K 3D laser-illuminated projection system.
