The main purpose of the park is to attract children, so try not to make the name too mysterious or too formal. It should be easy to understand, intuitive in expression, and eye-catching. Let me ask, which child knows what the Jurassic, Cretaceous, and Triassic periods are? Children of this era are not like our generation who grew up watching "Dinosaur Express".
Although children's consumption is dominated by parents, parents mainly make judgments based on their children's subjective wishes when making choices. I personally think that "Dinosaur Park" and "Dinosaur Playground" are good names. Children will understand at a glance that "Dinosaur", "Paradise" or "Amusement Park" can attract enough attention of children.
