'', based on these findings.
The cave was included on the Antiquities List of 1925,
but was not opened to the public until March 1933.
A museum was set up on site by the then-Curator of Natural History,
Joseph Baldacchino. Within a year of his appointment as curator in 1935, Baldacchino published a booklet on Għar Dalam, highlighting the main excavations and investigations of the cave.
The museum was slowly upgraded, new specimens replacing the old, and a labelling system set in place.
The showcases around the walls of the Għar Dalam museum house the skeletal remains found in the cave.
These are organised by species and type. The showcases in the centre of the museum's room contain complete skeletons of modern examples of deer, elephant and other species.
These were not found in the cave, but imported as reference specimens for the use of scholars working on the fossil examples.

Għar Dalam Cave and Museum is operated by
Heritage Malta. In 2019, a project was announced to improve the physical accessibility between Għar Dalam,

Stratigraphy

The cave consists of a number of sequential layers, which have been dated using
radiometric techniques.

Notes
:
Buhagiar (2007) notes that the name Għar Dalam does not mean the 'Cave of Darkness', as would be the case in Arabic, but the 'Cave of Dalam,' or 'of the Dalam family.'
The surname Dalam is attested in 15th century records.
