The second book, published a month later in 1918. Less dinosaurs, more of the various tribes of "early man" and their "evolution" from one tribe to the next. One too many last minute rescues, and instead of a message in a bottle (thermos), this time an entire boat load of people survived to return to California.

Glad to see the return of the dog, but disappointed in the angsty male lead and his female friend (referred to as a "half-baked savage" and "squaw"). Somebody who has read Twilight should compare it to this. Some sort of winged humanoid is described here also, but not further explored.

I'll read the third, and then cleanse my palette with [b:The Lost World|10155|The Lost World (Professor Challenger, #1)|Arthur Conan Doyle|https://images.gr-assets.com/books/1320504012s/10155.jpg|1098725].
