LIST OF GALADIMAS OF MANDARAGIRAU:  The Mandaragirau Galadimas who were then known as Thlermas were mainly from the Bwala clan. The lineage chart indicates that Thlerma Dikotum was the first Galadima and was succeeded by his son Tampci (2). The 3rd and 4th Galadimas were brothers and sons of the 2nd Galadima. The succession trend from the 4th to the 7th Galadima had been directly from father to son. It should however be noted that Yerma Tampci (5), Chapolajoda (6) and Yerma Aisami (7) ruled after 1918 when the Dagil clan ceased to be ruling Mandaragirau. The lineage chart produced by Whitely in 1918 was up graded later with their names. The list of the Galadimas did not however include those of Liya and Ngulde. Dlimbur, Tila Lake and Viukuthla village are some of the significant archaeological sites in the history of Biu and Mandaragirau chiefdoms. As it has earlier been mentioned, Dlimbur is the place where Yamtarawala settled when he came to Biu area. It is also the site where his tomb was located. It was said that in the olden days any new Pabir chief (Biu and Mandaragirau Mais) undergo some sort of initiation and baptism at the tomb. It was also a practice in those days that couples who had not begotten any child visit the site and offer sacrifices seeking for Yamta's blessing so that the woman could conceive and have a child as it was then believed. Usually such woman if she were lucky to give birth would name the child after Yamta if a male, and Awa (Awa Pacham, Yanta's mother) if a female. The Tomb and some of Yamtarawala's regalia are in the custody of a “Kadala” (the tomb caretaker) from the Zoaka clan in Mandaragirau. The site was however set ablaze by suspected Boko Haram insurgents on 20 November 2013. According to the records, the Tila Lake was full of crocodiles of a creamy colour which were different from those found in the surrounding rivers. The Tila crocodiles were sacred as they represented the spirit double of two or more clans; the Woviri clan of Chief of Biu, the Dagil clan of the former Chief of Mandaragirau and probably though not certain the amaza clan of Kwaya Bura and the lasama clan of Tila.
