👉 The term "hololith" is a type of fossilized rock formation that is composed mainly of silica crystals and can be found in various locations around the world. These rocks are typically formed from the remains of ancient plants or animals, such as those that lived during the Cambrian period (about 540 million to 345 million years ago). The presence of these fossils suggests that life may have existed on Earth millions of years ago and played a significant role in shaping its composition.
