[2] Materials removed from Trench A included fossiliferous breccia blocks from most, if not all, of the stratigraphic units present at the site (as well as loose fossil specimens sifted from decalcified sediments).

The first, GA 1, is a worn and fractured left molar that has not been confidently attributed to either genus or species (but resembles Homo in some features.

[2] In contrast, GA 2 is a complete left m2[clarification needed] that has been recently analysed and attributed to Paranthropus robustus (if from a large individual).

[3][10] A four-week excavation season produced a sample of 4,863 fossil specimens from approximately 50 m3 (1,800 cu ft) of soil overburden and naturally decalcified sediments that were screened with 1mm mesh.

This result highlighted the complex, heterogenous geologic processes that can influence fossil deposition and assemblage composition in South African cave systems during the late Pliocene and early Pleistocene.

The revised description of the GD 2 assemblage also reinforced several unique features of the collection compared to other South African late Pliocene and Pleistocene: The Gondolin Palaeo-cave deposits have been dated using a combination of biostratigraphy and palaeomagnetism which indicate an age of around 1.8 million years.
