SK16 1114–1115) Distribution: AB ( R ), petrified forest Remarks: The distribution of this taxon is still uncertain in many parts of its range because of possible confusion with Agama agama (but not in Kenya ), A. finchi , and A. dodomae ( Spawls et al. 2018 ) . This agama was only found in Alia Bay (three individuals including one juvenile NMK-398L/1 ( SK 16 1038b)) and in the petrified forest ( NMK SK1115). In the absence of rocks, this species was entirely arboreal, living on Vachellia sp. trees in the riparian woodlands along the dry riverbeds. Only in the rock-dominated petrified forest site (about 5 km from Karsa Gate, the southern entry point of SNP ) was this species rupicolous. We found Agama lionotus individuals ( Fig. 4B ) only between 1800 h and 2100 h. The average T b was 33.8 ± 1.7 °C (32.6–35 °C; N = 2) with T sub ranging from 30–34 °C and T a ranging from 32–35 °C.
