- Dark low-albedo spots and radiating streaks are noticeable on Al-Bakri's bright inner slopes. Apollo 15's orbital ITEK-panoramic frames AS15-P-9888 and AS15-P-9893 show remarkable high-sun close ups of Al-Bakri, looking very much like some kind of bright "lunar ring nebula".

Additional Information
- IAU page: Al-Bakri
- Depth data from Kurt Fisher database
- Westfall, 2000: 1.04 km
- Viscardy, 1985: 1 km
- High-albedo craterlet north-northeast of Al-Bakri, with smaller companion (a tiny ray-craterlet) immediately south of the larger one (see LRO's Act-React Quick Map). The floor of the larger high-albedo craterlet looks like some sort of valley. - DannyCaes Jun 9, 2012
Irregular Mare Patches (IMPs) in the neighborhood of Al-Bakri
- South-southwest of Al-Bakri (about halfway between Al-Bakri and the elongated hill unofficially known as the Seagull by the folks of the Hitchhiker's Guide to the Moon), at LAT: 13.95 / LON: 20.05 (2 examples, a large and a small one, the large one has a length of about 600 meters). - DannyCaes Oct 16, 2014
- North-northwest of Al-Bakri, at LAT: 14.6680, LON: 20.0460 (diameter about 200 meters). - DannyCaes Oct 16, 2014
Nomenclature
- Named for Abu Abdullah al-Bakri (1014–1094), a Spanish-Arab geographer and historian. He was born in Huelva, the son of the governor of the province. Al-Bakri spent his entire life in Spain, living in Cordova, and never travelled to the locations of which he wrote.
- The name Tacquet A was part of the original IAU nomenclature of Blagg and Müller (Catalog Entry 592). That name was a modification of Menelaus A, the name given to this crater by Mädler.
- This replacement name for a formerly lettered crater was provisionally introduced on LTO-60B1 (July, 1974). It was approved in 1976 (IAU Transactions XVIB). - Jim Mosher
- Felix Chemla Lamèch once proposed naming this crater Drossos, but that name was not accepted by the I.A.U.. Research: Ewen A. Whitaker and Danny Caes (August 2003, mail correspondence).
- A system of two arc-shaped remnants of ghost craters, south-southwest of Al-Bakri, is known as The Seagull, because of its typical shape. Thus nicknamed by David North and Akkana Peck.
- Three orbital Hasselblad photographs made during the mission of Apollo 15 show The Seagull in close-up: AS15-92-12540, 12541, and 12542. These three photographs are also online as King Size Hi-Res; in Kipp Teague's Project Apollo Archive (Full Hasselblad magazines). D.Caes research.
