Guys... this is embarassing. It's been known for many years that the Paluxy River tracks were embellished and outright faked by... guess who? Creationists. They're so embarrassed by this now that I've even seen these 'trackways' listed on creationist websites as arguments not to use.

It's just possible that some of the larger dinosaurs (as well as birds) did survive (and perhaps even do) in places like the Congo Basin. There's also a lot of folklore that is now known to derive from fossils (Adrienne Mayer wrote the definitive book on this - The First Fossil Hunters). All interesting stuff, with lots of unknowns, and I'd love Mokele Mbembe to turn out to be real.

The glib glossing over of the hundreds of thousands of detailed papers piecing together the geological past is just painful. There are some interesting problems out there, but this ain't one of them. Most of the dinosaurs really did die out around 65 million years, at the same time as a large asteroid impact.

These videos are trying to persuade you there's a conspiracy against the truth, and they're absolutely right. The conspiracy, though, is theirs. There's a branch of fundamentalist Christianity that wants you to throw away everything we as a species have learned about the past. You might want to ponder why that would be.
