The Secret of Sharktooth Hill (sounds like a Nancy Drew mystery) has recently been exposed. I originally had the impression that Sharktooth Hill was something that had recently been discovered, but that isn't the case. The paleontologists have just finally determined that it's a place where a lot of marine fossils got all collected into one area.
Bone Bed Tells Of Life Along California's Ancient Coastline
"This deposit, if properly developed, would look just like Dinosaur National Monument," said Lipps, referring to a popular park in Colorado and Utah. "(Sharktooth Hill) is actually much more extensive, and the top of the bone bed has complete, articulated skeletons of seals and other marine mammals."
[That'd be quite cool. I've been to DNM. Very impressive.]
And here's the big SECRET!
"The team's conclusion is that the climatic conditions were such that currents carried sediment around the bone beds for 100,000 to 700,000 years, during which time bones remained exposed on the ocean floor and accumulated in a big and shifting pile."
Then it got buried. Case closed!
Here's an example of what's found at Sharktooth Hill:
Chomp.
