Only about 10 percent of Göbekli Tepe has been excavated, and archaeologist Bahattin Çelik's survey identified at least a dozen other nearby sites with round buildings, T-shaped pillars, and animal carvings.
Notes on verification
Multiple independent sources corroborate both the ~10% excavation figure and Çelik's survey findings, including academic publications and Wikipedia's Karahan Tepe/Taş Tepeler entries.
