Bite-sized trilobites, starting 540 million years ago, were wandering around the ocean floors surviving and thriving. Dating back to this early fossil-era, the first-ever arthropods of the ancient times have an enthralling story to tell today. The Paleozoic era mariners, once part of the irreplaceable biodiversity in the ocean ecosystem, can now be discovered and unearthed in their fossilized form. Fossil collectors and commoners alike have been beguiled by this three lobed invertebrate seafarer.

Geologic time is the immense span of time that has elapsed since Earth first formed- almost 5.5 billion years ago-to recent times. The geologic time scale is a way of putting Earth’s vast history into an orderly fashion, giving a better perspective of events. At the turn of the nineteenth century, William Smith, an English Canal Engineer, proposed that the lowest rocks in a cliff or quarry are the oldest, while the highest are the youngest.

By observing fossils and rock type in the various layers, it was possible to correlate the rocks at one location with those at other location. These finding along with the first discoveries of dinosaur fossils, led to a framework that scientist still use today to divide Earth’s long history into geologic time scales.

What are the geologic time scales?

The table below is a listing of the geologic time table based on current interpretations of rocks and fossils:

When you have to determine if a fossil is genuine, plenty of tests like acid tests, X-rays, and radiometric dating could be performed. But for a fossil collector getting hands-on such expensive techniques is next to impossible and cost prohibitive. So what should you do, when you need to know whether a fossil you are about to buy is authentic or not? To help you out, here we have mentioned a few tips to go through:

Ever wondered why shark teeth are not mainly white but colored? From brown to dark gray, you will find different colors but hardly a white preserved tooth. If you believe it has got something to do with the age of a fossil or its type, the answer is unfortunately a big NO. A fossilized tooth of an extinct shark gets the color from the type of deposit in which it had been preserved all these years. To understand it in a better way, let’s just take a quick look at how a shark tooth gets fossilized first.

At any given time, a great white may have up to three thousand teeth in its five rows. The front row is probably the largest and strongest one. This row is used to bite and tear meat. In its lifetime, it can grow and use near about 20,000. One of the amazing things about great white is they never run out of teeth. When they lose one, another spins forward from the backup or reservoir in the jaw. This tooth replaces the old one and again, there is a strong row of teeth ready to snare small fish species.

The great white shark is the largest predator of the ocean, having thousands of sharp teeth that facilitates its role as a hunter under the water. If you want to feel the presence of this great fish, buy one fossilized tooth today.

If we start thinking about dinosaurs from our perspective in the 21^st century, they are terrifying and bizarre, in fact, dinosaurs were really intimidating. You may have seen their replicas in museums and research centers. If you want to see their power, shape and ability, watch “Jurassic Park” series. Most of us think that there were some freakish dinosaurs during the Triassic, Jurassic and Cretaceous period.

The first dinosaur fossil was found in the 19^th century. Since then, they have become an enduring part of world culture, even; you can find dinosaur teeth for sale at many online stores. Here, we have a list of five freaking dinosaurs whose skeleton have not been found as of 2014.

Do you know how many teeth does a white shark have in its entire life? Is it an easy question? There is probably no easy answer when great white shark teeth are concerned. They probably have 24 exposed teeth on its top and lower jaws. But behind, there are five rows that regularly loose teeth and develop within a short period of time. In this way great whites spare hundreds of teeth in their lifetime.

King of the ocean:

Great whites are called as king of the ocean, because they instill both terror and awe in most of us. The average length of a great white was 15 feet long and 5,000 pounds weight. These creatures often attack on unwitting swimmers. Although the Megalodon is the largest, this species is also considered as an undisputed ruler of the sea.

Who could be the most deadly predator of the ocean? Yes. You are right. It’s giant shark and the ultimate predator were the Megalodon that existed some 10 million years ago. Today, this species exist only in the fossil record. Megalodon had hundreds of tooth to spare and 5 rows of teeth to kill its traitor. Today, owning one tooth can be the symbol of status, especially for those who appreciate the history of the ocean.

At Buriedtreasurefossils.com, we have high quality fossil shark teeth and top quality Megalodon teeth for sale. We have fragmented these teeth into different categories according to their location. So, you can shop these teeth by their location.

The shark is an image of both magnificence and threat, and has been since humanity took their first treks into sea waters. A shark has a grin few can overlook. The Megalodon shark teeth are not connected deep down of the jaw, but rather are really inserted in the dental layer. Dissimilar to people, sharks shed their teeth ceaselessly all through their lifetime. Like a carpet lift, they are advanced so that the shark is never without, in light of the fact that being without teeth would parallel passing for the creature. The turnover for a tooth speaks the truth like clockwork, and for an extraordinary white shark generally sheds each one hundred to two hundred and thirty days, contingent upon the age of the shark.

Trilobites went entirely extinct at the end of the Permian period. During this period all species of trilobites were extinguished and the pattern of decline for trilobites had been apparent since the end of the Ordovician. Towards the end of the Devonian period, Phacopidae went extinct and all of the orders had gone barren, except the Proetida. This order prevailed into the Carboniferous. Today, these trilobites considered as buries treasures and we have a huge number of beautifully created Moroccan trilobites for sale. They were copious during the Paleozoic period, but went extinct at the end of the era.

We have different catalogs of these popular fossils. We have also fixed an affordable price for each one of our fossils. Let’s have a look at some of the highly popular trilobites available in our catalog.
