Libyco-Berber alphabet
The Libyco-Berber alphabet or the Libyc alphabet is an abjad writing system that was used during the first millennium BC by various Berber peoples of North Africa and the Canary Islands, to write ancient varieties of the Berber language like the Numidian language in ancient North Africa. The Libyco-Berber script is found in thousands of stone inscriptions and engravings throughout Morocco, northern Algeria, Tunisia, northern Libya and the Canary Islands. Apart from thousands of small inscriptions, some of the best known and significant Libyco-Berber inscriptions are in the Massinissa Temple (discovered in 1904) and the Prince Ateban Mausoleum in Dougga / Thugga (TBGG), northern Tunisia. Other significant Libyco-Berber inscription are the Azib N'Ikkis and the Oukaimeden, both found in the High-Atlas Mountains of Morocco. The use of the Libyco-Berber alphabet died out in northern areas during or after the reign of the Roman and Byzantine empires, but it spread south into the Sahara desert and evolved there into the Tuareg Tifinagh alphabet used by the Tuareg Berbers to this day. Description 
Before, during, and after the existence of the ancient Berber kingdoms of Numidia (northern Algeria, 202 BC–40 BC) and Mauretania (northern Morocco, 3rd century BC – 44 AD) many inscriptions were engraved using the Libyco-Berber script, although the overwhelming majority of the found ones were simple funerary scripts, with rock art, cave art, graffiti, and even a few official governmental and possibly religious inscriptions have been found. The Libyco-Berber script was a pure abjad; it had no distinct vowels. However, it had equivalents for "w" and "y", and "h" was possibly used as an "a" too. Gemination was not marked. The writing was usually from the bottom to the top, although right-to-left, and even other orders, were also found. The letters took different forms when written vertically than when they were written horizontally. The letters were highly geometrical. Variations 
There are multiple variants of the Libyco-Berber script; some studies divide these varieties into eastern and western, while others have identified more than 25 "dialects" grouped in 5 different families. The eastern variant was used in what is now Constantine and the Aurès regions of Algeria and in Tunisia, and to an extent Kabylia. It is the best-deciphered variant, due to the discovery of several Numidian bilingual inscriptions in Libyco-Berber and Punic (notably so-called KAI 100 and 101 at Dougga in Tunisia). Since 1843, 22 letters out of the 24 have been deciphered. Signs used at Dougga (when writing direction is from right to left):

The Western variant was used along the Mediterranean coast from Kabylia to the Canary Islands. It used 13 supplementary letters. As of 2002, much of the Western variant has yet to be deciphered. Western variant signs have also been observed to be used in combination with possible pictograms of animals. Origin
The origin of the Libyco-Berber script is still debated by academic researchers. The leading theories regarding its origins posit it as being either a heavily modified version of the Phoenician alphabet, or a local invention influenced by the latter, with the most supported view being that it derived from a local prototype conceptually inspired by a Phoenician or archaic Semitic model. Other unlikely explanations include Greek, Punic or South Arabian influences. One of the oldest known variants of the script is found in inscriptions in Dugga dating from Numidian times. References
