A recent study published in Geology found that sedimentary rock can form in as little as 35 years.^1,2 Before this, conventional geologists thought these types of rocks took vast amounts of time to erode, consolidate, and lithify. What they discovered along the coast of Scotland caused them to quickly change their minds.

In 1988 a fossil jaw was discovered by paleontologists in San Diego County, California.
