REX Kyouryuu Monogatari

Chie lives in Hokkaido with her archaeologist father, while her mother is a scientist based in America. During a cave excavation, they uncover Tyrannosaurus eggs that are on the verge of hatching. As the eggs open, a small dinosaur emerges and begins to regard Chie as its mother. She takes responsibility for the creature and tries to shield it from others who seek to conduct experiments on the young dinosaur.
