And while certain signs span thousands of kilometers, other signs had much more restricted distribution patterns, with some being limited to a single territory, like we see here with these divided rectangles that are only found in northern Spain, and which some researchers have speculated could be some sort of family or clan signs.
Meski beberapa simbol tersebar sejauh ribuan kilometer, simbol lainnya memiliki pola pesebaran terbatas, ada yang hanya terdapat di satu wilayah, seperti persegi terpisah ini yang hanya ditemukan di bagian Utara Spanyol, yang menurut perkiraan peneliti adalah semacam simbol keluarga atau suku.
