The Diplodocus


Diplodocus is an extinct genus of diplodocid sauropod dinosaurs. The name is derived from Greek διπλός "double" and δοκός "beam", in reference to its double-beamed chevron bones located in the underside of the tail. Once the most famous dinosaur in the world, Diplodocus had four large sturdy legs supporting a long neck and a long tail that could be flailed around like a whip. It was huge and may have reached over 30 metres and weighed around 15 tonnes.
They lived there about 150 million years ago during the late Jurassic period they thrived in a time when the Earth's warm temperatures encouraged rapid plant growth. Diplodocus needed a lot of food to keep it alive. Using rake-like teeth, this animal could have stripped an area of any vegetation very quickly, especially considering that there is evidence they travelled in herds, the quantity of plant material eaten by these massive herbivore must have been considerable. Diplodocus' tail was about 14m long, which is one of the longest tails of any animal to have ever walked the earth. Like most Sauropods, Diplodocus' nostrils were actually high up on its forehead instead of at the end of its snout. A recently discovered fossil of a skin impression suggests that this animal had spines along its neck.

Ankylosaurus is a genus of armoured dinosaur. Its fossils have been found in geological formations dating to the very end of the Cretaceous Period, about 68–66 million years ago, in western North America.

Scientific name: Ankylosaurus
Mass: 4,000 – 7,000 kg (Adult)
Height: up to 1.7 m (Adult)
Length: 7 – 11 m (Adult)
Higher classification: Ankylosauridae

Did you know: Ankylosaurass
    1. Means ‘fused lizard’.
    2. Had four horns on its head.
    3. Lived at the end of the Cretaceous Period (around 66 million years ago).
    4. Were one of the last dinosaurs remaining before the large extinction
    event that occurred around this time.
    5. Was a large dinosaur, it reached a length of  around 9 metres  and
    a weight of around 6000 kg.
    6. Were herbivores (plant eaters) and had small teeth relative to their body
    7. Had body armour made from huge plates of bone which were embedded
    into the skin which helped protect it against attackers. Similar body armour
    is found on a crocodile or armadillo.
    8. Had a massive tail club that it could use to generate a large amount  of
    force potentially breaking the bones of another dinosaur while defending

Archaeopteryx is a bird that has sparked quite a bit of debate ever since its fossils were discovered in Germany in the mid-19th century. It was described and named by Hermann von Meyer in 1861. Its name means “ancient wing.” It lived during the Late Jurassic Period, about 150 years ago and flew over what is now known as Europe, but at the time was
an archipelago of islands in a shallow tropical sea, much closer to the Equator than it is today.

Similar in shape and size to a modern-day magpie, Archaeopteryx was 30 cm long, and weighed between 300 - 500 grams. It had legs that were longer than what birds usually possess and its wings were asymmetrical – which means that it probably used them to generate lift for flight. However, what scientists don’t currently know about this bird was whether it could fly by flapping its wings or if it had to employ some form of gliding strategy.

Some scientists have referred to it as a bird-like dinosaur and other scientists have referred to it as the first bird.The truth, most likely, is that it is a “missing link” between dinosaurs and birds and was in a transitional form between a dinosaur and a bird.Despite its small size, broad wings, and the inferred ability to fly or glide, this prehistoric animal had more features in common with the other dinosaurs from the Age of Reptiles (such as jaws full of sharp teeth, long bony tail, etc.) than with modern birds.

Archaeopteryx pictures show this bird with a wide-variety of different colors of feathers. Some artists show them as having blue or green feathers accented with red and gold, while other artists show them as being solid colors such as brown or gray. However, the truth of the matter is that the feathers of this bird were more than likely black. This has been confirmed using X-ray analysis of the fossils.

One of the most interesting facts about Archaeopteryx is that it might have had a primitive warm-blooded metabolism – meaning that it could generate body heat on its own. However, its metabolic system probably wasn’t as fine-tuned as warm-blooded animals today, so it had a slower growth rate than most birds and probably ate a lot less. It was a carnivore, so it probably fed off of some of the small animals that were available at the time.

Archelon (from Greek αρχελών meaning ruler turtle) is a genus of extinct sea turtles, the largest genus of sea turtles that has ever been documented, and the second-heaviest turtles documented behind Stupendemys.
The largest Archelon fossil measured more than 4 metres long, and about 5 metres  wide from flipper to flipper. It was a marine turtle, whose closest living relative in the present day is the leatherback sea turtle. It lived at a time when a shallow sea covered most of central North America. Most of the known remains have been found in South Dakota and Wyoming. Though anatomically similar to the earlier species Protostega gigas, it was much larger. Unlike most modern turtles, Archelon did not have a solid shell, but instead had a skeletal framework supporting a leathery or bony carapace. Other distinguishing features include a pointed tail, a narrow skull, a relatively narrow, high-vaulted shell, and a pronounced overbite. The live weight of an Archelon is estimated at more than 2200 kg. They probably had a very strong bite, and were optimized for feeding on pelagic mollusc's such as squid.

 Quetzalcoatlus (KWET-Sal-coh-AT-lus)

Image result for quetzalcoatlusWas an azhdarchid pterosaur known from the Late Cretaceous of North America (Maastrichtian stage)  It is a member of the family Azhdarchidae, a family of advanced toothless pterosaurs with unusually long, stiffened necks.

Its name comes from the Mesoamerican feathered serpent god, Quetzalcoatl. With a wingspan of 12 metres and a weight of 65kg, Quetzalcoatlus was the largest flying animal ever. It probably soared over inland areas, looking for carcasses to eat. 


Image result for coelurosauravusCoelurosauravus (meaning "hollow lizard grandfather") is a genus of basal diapsid reptile that lived during the Upper Permian (Lopingian) period in Northern Europe - Germany, England and Madagascar. It had specialised wing-like structures allowing it to glide. These were rod like structures with skin stretched over them. These bony rods are not extensions of the ribs but are newly evolved dermal bones, a feature which is unique to the genus.The average length of the specimens was 40 centimetres and the body was long and flat, suitable for gliding. The skull was lizard-like with a pointed snout and contained a broad back with a serrated crest, superficially resembling the crests of ceratopsian dinosaurs.
