Impressive CGI offers glimpse into ancient creatures' lives.
Parents need to know that this series’ focus on ferocious prehistoric beasts means that there are lots of confrontations between the computer-generated images of the predators and their prey, whom they bite and disembody -- usually with plenty of bloody (though it's all re-created). There are also occasionally additional live-action video clips of modern animals hunting. That aside, there’s plenty of educational content in this intriguing show, and the material is relatable since it references modern regions that are rich in prehistoric evidence and current creatures that resemble extinct species. Expect a few references to and images of breeding practices, but nothing too eyebrow-raising.
