Dino Doug has wanted to see a dinosaur his whole life...and finally his dream is coming true. He’s built a large refuge for prehistoric animals, and with the time machine he’s had built for him, Dog is going to bring the dinosaurs and other prehistoric animals back from extinction. He and his carefully chosen team of experts will travel far into the past to search for an ancient hornless rhino, the Aceratherium. Amongst the ancient Miocene scrublands Doug and his team will encounter animals very similar to ones on the moderns Serengeti. But, unlike today’s lions and hyenas lurk cooler even hungrier predators.
