For a long time, paleontologists believed that dinosaurs were just land dwellers. They were of this view because they had not discovered fossil remains which would have made them think otherwise. But now, it is becoming sure that swimming dinosaurs possibly existed as well. Paleontologists have been trying to form a model of Spinosaurus for more than a decade. Most of them agreed that this dinosaur had different anatomy than land-dwelling dinosaurs, but they were not sure whether Spinosaurus was capable of swimming or not. But when fossil bones from Spinosaurus’ tail were discovered in south-east Morocco, paleontologists had to rethink about this massive meat-eater dinosaur’s capabilities.

Before we delve into the details of the fossil discovered, let’s first talk about Spinosaurus’description. The first fossil of this dinosaur was found in Egypt around 1910. We all hear so much about Tyrannosaurus Rex being the biggest dinosaur ever. This is not true as Spinosaurus was bigger and perhaps

Carcharocles augustidens is a species from the Carcharoles (or Otodus) genus of the megatoothed sharks. Modern-day researchers believe that this species should not be placed with Great White shark genus. The specimen believed to belong to the extinct white shark is one of the most complete of its kind in the world. Compared to any living white shark, Carcharocles augustidens were much larger and heavier. The fossils that have been discovered included more than 150 teeth and multiple vertebrae. If you’re looking for Angustidens shark tooth for sale, here are four facts that you should know about the species before buying the shark tooth.

Fact 1

The large-sized Angustidens mean that the species must have been powerful predators that could only be rivaled by gigantic sharks and large raptorial sperm whales like the Brygmophyster. A wholly grown adult Augustiden probably fed on small to medium-sized cetaceans like small whales and dolphins. Juvenile Angustidens may have hunted fish and smaller

Ever wondered how the Cow sharks got their name? Or what makes them so special or different from other sharks that there are now Cow shark teeth for sale?

As insignificant as these questions may seem, the answers are sure to pique your curiosity and interest in Cow sharks. And who knows, you might get yourself a Cow shark tooth for sale after learning about them?

What are Cow Sharks?

The Cow sharks come from a shark family popularly known as Hexanchidae. The term “Hexanchidae” came from Greek, which means "six arches," referring to the fact that some Cow sharks have six-gill slits.

So far, five species of cow sharks have been identified, namely Sharpnose Sevengill, Broadnose Sevengill, Bluntnose Sixgill, Atlantic Sixgill, and the Big Eyed Sixgill.

Of all the species, the Bluntnose Sixgill Shark (Hexanchus griseus) is the biggest, having six gills and a blunt nose, and Atlantic Sixgill is the most recently discovered Cow shark in the family.

What Makes Cow Sharks Special?

Having six-gill

The mention of these happy aquatic creatures often paints the picture of Florida's popular dolphin show at Sea World theme park. The grandeur of the cresting dolphins surrounded by soaring tropical rainbow birds and a happy child petting the aquatic mammal as one of the many reaches up to the audience area. The unison of the sky and water as the realms' majestic creatures come together is quite a dreamy visual experience. Indeed, dolphins are impressive, but the cetologists and other researchers looking for dolphin tooth for sale for studying them might have a different opinion. Their perpetual grin and an overall pleasant demeanor can be misleading. This blog talks about five dangerous facts about these seemingly "gentle and harmless" creatures.

They bite and attack

Fancy a dolphin tooth fossil for sale? These teeth do more than just smiling. Dolphin teeth are very sharp and designed to attack and ravenously kill their prey. Apart from being sharp, dolphins have many teeth in their set

Like any other branch of science, paleontology is constantly evolving. Somewhere some fossil crops up, and experts examine them as evidence and come up with tentative theories. Now, the real test lies in whether those theories are able to endure through time and against counter arguments and criticism from contemporary and future scientists. And when you work on something long enough, especially something like dinosaurs that existed millions of years ago, some misconceptions, misunderstandings and incorrect theories are bound to appear and disappear over time.

Here are some such historical facts about dinosaurs that have now been disproved:

1. The Stegosaurus had a butt in its hindquarters

In 1877, the discovery of the Stegosaurus baffled naturalists who were still not aware of the existence of giant lizards with bird-sized brains. This was the reason why Othniel C. Marsh, a renowned American paleontologist, introduced the idea of a second brain in the dinosaur’s hip, the function of which

Are you a fossil collector? You must have heard about the recent discovery of three partial skeletons of a raptor dinosaur by U.S paleontologists back in 2014. The dinosaur was named Anzu wyliei. In Sumerian mythology, ‘Anzu’ is a bird-like demon; ‘Wyliei,’ the species name, which honors Pittsburgh’s Carnegie Museum’s Trustee’s grandson.

If we talk about appearance, the creature who lived almost 66 million years ago when the king of the dinosaurs, T-Rex, also roamed around the earth, looks like a modern emu’s and a reptile’s cross.

From one fossil enthusiast to another, Anzu claws for sale are available with us, and they will be a great addition to your collection!

Where were the Anzu fossils discovered?

The specimens were extracted from the Hell Creek Formation in the North and South Dakota’s uppermost level. Due to its bird-like appearance and the place of discovery, the creature was jokingly referred to as the “Chicken from Hell.” If you are not aware of Hell Creek Formation’s significance,

Finding fossils is certainly exciting — you found traces of something that existed millions of years ago. But preserving them is difficult, as they are quite delicate, demanding your utmost attention. To keep them safe as historical items, it’s vital to put proper care in place, and this stands true even for the fossils that you buy, whether it’s Hemipristis shark tooth for sale or an extinct pine cone.

Here’s your quick guide to caring for fossils:

Clean them before storage

The first step to preserving fossils is to clean them to get rid of dirt and residue. For fossils found on the land, you can use a soft brush for cleaning. For those discovered from a sea setting, use a mild solution of bleach and water. Soak them in the solution for a few minutes and then brush them to remove salt residues. Make sure to handle and brush them gently, as they are fragile.

Fix broken parts

Fossils are millions of years old, which makes them susceptible to breakage and developing cracks. Most fossils that

We all have seen them, touched them, and wondered about them, but not a lot of us know what actually happens within a female pine cone. We are specifically talking about the female pine cone not because we have anything against the male cones. The truth is, the majority of the visible cones in the forest are mostly female ones. The reason behind this is male cones’ smaller size, which makes them less conspicuous than its counterpart.

In this article, we’ll explain to you in brief what happens inside the female cone. We’ve listed down some points for this purpose. Let’s take a look at them.

• Let’s start with female pine cone formation. In the months of spring, mostly in the uppermost branches of the pine tree branches, small, green female pine cones begin to form. They come out of those branches that instead of adapting leaves, have formed scale-like structures. In these scales, you will find on the upper side, two ovules, both of which turn into a seed. All of this happen when the female

Sperm whale, also known as cachalot, is the world’s largest toothed whale and is easily recognized by its enormous head and narrow jaw. These active predators, who prey on squids and bony fishes, are dark blue, brown, and grayish with white patches on their belly.

Despite big, square head, sperm whales are good at catching their preferred prey with their large conical teeth. Not only do they have large brains, but they also have the most powerful sonar that they use to find prey in the deep ocean. They have an incredible ability to dive to incredible depths in the sea. They can even stay down for several hours, which increases the likelihood of catching prey in the deep. Due to this predatory behavior, sperm whales generally live in deep water and are rarely seen along the coast.

Specialized sonar organ, known as a melon, and very large brain contribute to sperm whale’s characteristic block-shaped head, which is easy to identify. Their lifecycle is similar to that of humans, but female

When Steven Spielberg made his 1993 blockbuster, Jurassic Park, not much was known about the Tyrannosaurus rex, or T. rex, as it is more popularly known. Back then, there were only around eight skeletal remains in the fossil record. But since then, more skeletons have been unearthed, which have changed paleontologists’ and even the general public’s understanding of the “king of dinosaurs”. In the recent years, there are numerous findings that have upended the preconceived ideas of how this creature looked, behaved and ate. Here aresome of these ideas that have been proved to be wrong.
