What is a living fossil?
Fossil… isn’t that something that scientists find in the ground?
Sometimes a fossil is something scientists find in the ground. These special scientists are called paleontologists. Their job is to look for clues about prehistoric life by examining fossils.
The word fossil refers to something that has been buried and compressed (or pounded down) by tons of sediment for at least 10,000 years. During shifts in the Earth’s crust, these fossils are exposed and rediscovered.
There are also living fossils. Living fossils are plants and animals that exist today, but look almost exactly like they did in prehistoric times. Many living fossils were even pronounced extinct at one time!
Here at the Maine Discovery Museum, we have two living fossils that you can investigate. The first are turtles and the second are cockroaches. Both of these have been around for millions of years and still look very much like they did in prehistoric times. We also have triops that will be hatching soon in the Dino Dig exhibit.
Some living fossils are still to be discovered. You could be the one to discover new, old living fossils! In 2007, a rare living fossil called the frilled shark was seen by a fisherman in Japan. Up until then, scientists believed the frilled shark to be extinct for millions of years.
