Before B.C.
since the prehistoric ages about 95 million years ago
Frilled sharks have existed for around 80 million years, making them one of the oldest species of sharks still around today. Their unique physical characteristics and deep-sea habitat have allowed them to remain relatively unchanged over the millennia.
Turtles have been around longer than sharks, with the earliest known turtle fossils dating back over 200 million years, while sharks have been around for about 400 million years.

Sharks have been around for about 409 million years but before they evolved they were around for 890 million years.Sharks have been around for about 409 million years but before they evolved they were around for 890 million years. TRUE!Over 400 million years!Shakrs have been alive for a very long time. They have swam the waters of earth since about 409 million years ago. This period of time was before our first dinosaurs came to be infact.
Frilled sharks are typically found at depths ranging from 390 to 4,200 feet (120 to 1,280 meters) in the ocean, although they have been recorded at depths of up to 5,150 feet (1,570 meters). They are considered bathydemersal, meaning they inhabit deep waters near the ocean floor.
Sharks have been around for hundreds of millions of years. This means that their teeth have been available to the fossilization process for a long time.
Chances are, unless we kill them off with pollution, sharks will be here millions of years after us. They have been around for more than 60 million years in present form - man as man has only been here for 5 million years. They are the perfect living organism (they eat and breed... that's it!!)
Frilled sharks have never been kept in captivity. In the wild it is hard to know just how long these fish live. Because they are deep benthic creatures there is little information on lifespan. However, one source (Parker and Parker, 1999) estimates maximum lifespan at 25 years.
