In many types of dating you can follow the beds to adjacent places that have been dated. This is what they did, and what they mean by an adjacent basin. Of course ichnofossils including tracks are found in diverse types of sedimentary rocks, and hominins tracks are known from beach deposits such as the oldest known human fossils (tracks) from England. “Calcareous nannoplankton data from sediments exposed near Trachilos and belonging to the same sub-basin indicate deposition during calcareous nannofossil biozone CN9bB, between 6.023 and 6.727 Ma._______________________________________________________________________________From the Nature article “Calcareous nannoplankton data from sediments exposed near Trachilos and belonging to the same sub-basin indicate deposition during calcareous nannofossil biozone CN9bB, between 6.023 and 6.727 Ma.”

This dating study establishes the age of the rocks at Trachilos Beach to be Miocene. They mention that the rocks are shallow marine. They also report that there are no beach deposits at Trachilos Beach until sometime in the Pleistocene. If they had mentioned that mammal footprints in shallow marine sedimentary rocks are otherwise unknown in paleontology, their paper would not have been accepted in Nature.
