瑪麗．波．奧斯本(Mary Pope Osborne) 、娜塔莉．波．博以斯(Natalie Pope Boyce)
　　瑪麗與娜塔莉是姊妹，從小隨著從軍的父親旅居世界各地。今天，瑪麗住在美國紐約市與康乃狄格州；娜塔莉則住在麻薩諸塞州。瑪麗為美國知名兒童文學作家，筆下的「神奇樹屋」系列書籍廣受好評，深受孩童喜愛。瑪麗與娜塔莉合力寫作了多本神奇樹屋小百科。
　　他們兩人針對本書的創作表示：「研究冰河時期真是太有趣了。娜塔莉曾住在亞利桑那州的一個農場附近，有一天，大雨過後，農場主人發現泥堆裡有些奇怪的骨頭。結果科學家告訴農場主人，那是冰河時期長毛象留下的遺骸！那裡還有許多野牛骨頭，以及矛頭、工具。其他如駱駝、熊等動物的骨骸，也都曾在亞利桑那州的那個地區出土。在住家附近竟然能發現這些東西，真是令人覺得歷史栩栩如生的浮現眼前。想像一下……也許曾經有隻長毛象，走過娜塔莉的花園那塊土地上呢！」
