Old Rock Day is celebrated on January 7th of each year. The staff at National Whatever Day were unable to discover the origin of Old Rock Day, however it is a perfect opportunity to learn a little something about fossils and other old rocks.
Ever since recorded history began, and probably before, people have noticed and gathered fossils, including pieces of rock and minerals that have replaced the remains of biologic organisms, or preserved their external form. Fossils themselves, and the totality of their occurrence within the sequence of Earth’s rock strata, is referred to as the fossil record.
The fossil record was one of the early sources of data relevant to the study of evolution and continues to be relevant to the history of life on Earth. Paleontologists examine the fossil record in order to understand the process of evolution and the way particular species have evolved.
