    Learn What Makes Cow Sharks Stand Apart From Other Sharks

    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 slits alone is unique, considering the fact that almost every shark found today has only five-gill slits. And don’t be flabbergasted if we say that two of the cow sharks have seven gills.

    The Sharpnose Sevengill and Broadnose Sevengill, as the names suggest, have seven gills, though they are a rare sight.

    Another peculiar feature that makes them stand apart from the sharks of other species is their teeth. If you know how their teeth look like, you will have, in all likelihood, no trouble differentiating them from other sharks.

    Cow sharks' teeth shape is one of the significant distinctions, with the lower lateral teeth resembling a unique rectangular shape. These lower lateral teeth are covered with a row of cusps that gets shorter as it moves towards the distal end. Due to the structure and appearance of their teeth, many experts compare their lower teeth

    5 Dangerous Facts About Dolphins: The Truth Behind These “Gentle” Creatures

    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 to make their attacks impactful. For instance, the bottlenose dolphins can have between eighty to a hundred teeth in their mouth for a firm grip and ultimately secure their prey for consumption. Additionally, at times these mammals might attack an animal (including humans) without any intention of preying on them via a strong blow with their snouts.

    They torture their food before eating it

    Well, dolphins can be pretty sadistic too. On one note, they do it to prey on rather harder to attack creatures like octopuses who have deadly tentacles around for defense. Dolphins maul and beat them up to break them into smaller pieces before eating them.

    4 Historical Facts About Dinosaurs That Have Been Disproved

    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 was to control the rear part of the animal’s body. This idea was widely refuted and it was found that the cavity in the hip was used to store glycogen.

    1. The Archaeoraptor blunder

    The Archaeoraptor fossil, which reportedly came from the Early Cretaceous beds of China, was presented by National Geographic magazine as the best evidence that proved the theory that birds did, in fact, evolve from dinosaurs. It was, however, later found that the fossil was not authentic and was a forgery created using rearranged pieces of fossils of other species. Thi

    Fossil Enthusiasts Here’s What You Should Know About Anzu wyliei

    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, it is highly valued because of the abundance of T-Rex and Triceratops fossils found there.

    The discovery of these skeletons was nothing short of a breakthrough as it provided a much-needed opportunity to understand a dinosaur group about which not much was known. After remaining enveloped in mystery for about a century, the 2014 extraction allowed the scientists to shed light on the anatomy as well as Caenagnathidae’s evolutionary relationships. Anzu is a Caenagnathidae, a type of Theropod group dinosaurs.
