Fast-forming Chalk Beds

Did you know chalk is actually the fossil remains of the shells of many microscopic creatures? Well, supposedly, it took forty million years to form the chalk beds we see today. As tiny creatures died, their skeletons mixed with lime on the ocean floor. The ooze eventually became chalk.

Mixed in with these tiny marine creatures are fossils of fish, turtles, pterosaurs, sharks, and even dinosaurs! So, how did large ocean—and land—creatures end up, uneaten, on the ocean floor?

So should we—ahem—“chalk it up” to millions of years? No! The layers of soft limestone we use as chalk were formed quickly, during the global flood.
