Xenozoic is a big book. It's a cool story about Earth in the future, after climate change has devastated the world and man has retreated underground for 500 years. Returning to the surface, the survivors are surprised to find that the earth has changed- many of the life forms they knew are gone, and dinosaurs once more roam the world. And other creatures as well...
the story revolves around Jack Tenrec and Hannah Dundee- he's a mechanic, she's a tough diplomat who has come to a sunken New York for her own reasons- as they struggle to survive in a hostile world. It's pulpy adventure, with black and white art reminiscent of the old lost world kind of stories, and a lot of fun. It's got the usual adventure bits, and Mark Schultz the creator is noted for seeding cautionary notes about environmental degradation in the stories.
Xenozoic is perhaps better known as Cadillacs and Dinosaurs, which was the name of a trade paperbacl collection and that name kinda took off. I've only discovered this recently and am enjoying the romp through a prehistoric/ futuristic setting.
Here's the full effect.
