Dinosaur Sanctuary Vol. 1 (manga)

In 1946, someone discovered an island where dinosaurs had survived into the present. Through breeding and genetic manipulation, humans managed to increase their population and supercharge their popularity! Until, well... the unfortunate accident, when people's attitudes soured on the idea of visiting dinosaurs.

This story follows a rookie zookeeper who is newly hired at Enoshima Dinoland, a struggling dinosaur sanctuary, and the fascinating creatures who need specialised love and care!
