Do you know an animal particularly well? Like a dog, or a dinosaur? Choose one and write as much as you can about it!
Dinosaurs, meaning “terrible lizard” in Greek, lived in the Triassic through the Cretaceous period. Excavating new fossils showed lots of knowledge about dinosaurs and how it makes them a unique animal. This piece is all about dinosaurs, what kind of dinosaurs there were, what they ate, and how they became extinct.
There are many different types of dinosaurs. Theropods were bipedal carnivorous dinosaurs. Some were fairly small, like velociraptors; some were as big as a Tyrannosaurus rexes. Sauropods were another group of dinosaurs. These creatures were prodigious quadrupedal herbivores with long necks, long tails, and massive limbs. Brachiosaurus and Argentinosaurus were huge sauropods. Stegosaurus is the genus of the well known stegosaurus stenops. These herbivorous armored lizards had spikes on their tails for self defense. These are only a few of the countless types of dinosaurs.
The two main types of dinosaur diets were herbivorous and carnivorous. Carnivores, like Tyrannosaurus rex and Velociraptor, only ate meat. Therefore, they ate other dinosaurs as a food source. Herbivores, like Brachiosaurus and Stegosaurus, preferred plants instead of meat. Since they were hunted by carnivores, these creatures used special weapons built into their body for self defense. The argentinosaurus defended itself by whipping its tail at foes. On the other hand, the stegosaurus had a spiked tail to smash its enemies. Omnivores, which eat both, were very special creatures. Omnivorous dinosaurs, like Gallimimus ate plants, meats, and even insects. Gallimimus didn’t have any self defense, but it adapted to run extraordinary fast. These are the different type of food dinosaurs ate and how they defended themselves.
Dinosaurs are an extinct genus of reptiles, but how did they become extinct? These terrifying lizards died out about 65 mya (Million Years Ago) during the Late Cretaceous Period. Meteors and volcanoes killed them off. Evidence of these meteor craters can be found in certain parts of our world. Even though dinosaurs became extinct, mammals survived this event and carried on, evolving into the mammals we see today (including ourselves). If dinosaurs still roamed today, humans wouldn’t have existed, and a strange world would have lived on.
Even though these creatures are extinct, they remain interesting. Dinosaurs are especially well known despite the fact that they are not alive today. This makes them a big part of history and a unique group of animals.
