Found more than ten years before the publication of Charles Darwin's Origin of Species and eight years prior to the famous discovery in the Neander Valley, the significance of the find was not understood at the time, and the skull was simply labelled as "an ancient human, died before the universal flood" and lay forgotten inside a cupboard at the Garrison Library for many years.After the publication of Origin of Species, a renewed interest in the fossil human remains led to the skull being brought out of obscurity and presented at a meeting in the British Association for the Advancement of Science in 1864.This allowed many marine biota to spread, such as the ammonites and belemnites into north-western Europe.

The goal is to constrain the ages of the main vertebrate fossil-bearing successions and to place the different vertebrate assemblages within a robust, accurate and precise chronostratigraphic framework.

Such an endeavour will allow identification of potential faunal evolutionary trends (e.g., changes in taxonomic composition, diversity and/or abundance, trends in morphological evolution or body size modifications) as the Transylvanian faunas approached the K-Pg boundary.

Its discovery predates that of the "original" Neanderthal discovery but no one realised its importance at the time and it lay forgotten in a cupboard for years.

The location and context of this discovery is unclear making specific dating of the skull impossible.

The original find was done in a time where the palaeontological dating was still in its infancy, and no stratigraphic information was supplied with the skull, making dating at best guesswork.

Another specimen from a different locale on Gibraltar (Gibraltar 2) has however been dated to between 30 thousand to 50 thousand years old.

For example, coccoliths are known to only live in warm waters.

Distributions of these forams in the Late Cretaceous were widespread.

These caves may have represented the refugium of Gibraltar's Neanderthals.
