It was a medium-sized predatory therapod. Yutyrannus means 'feathered tyrant'. It was the first somewhat large therapod to be discovered with feathers. Discovery of Yutyrannus Yutyrannus was described in 2012 and was a game-changing discovery. It was the first large therapod to be discovered with feathers. Why is Yutyrannus Important? Yutyrannus' discovery led to paleontologists to realize that Large therapods too might have had some type of feathering.  It made them realize that large dinosaurs were more bird-like than previously thought. Yutyrannus Habitat Yutyrannus lived in Early Cretaceous China in the Yixian formation. It lived in very cold environments and had a feathered coating to keep it warm in the harsh habitat. Sinosauropteryx might have lived with Yutyrannus. Yutyrannus Size It was 9 m

The (mostly huge) ocean-dwelling mammals. Well, they weren't always this way, in fact whales were actually first land-based. And I am going to explain that right now, The Evolution of Whales.   When Mammals Became Rulers As I said at the end of my  How The Non-Avian Dinosaurs Went Extinct  post, after the Dinosaurs' domination, mammals diversified and evolved. They became bigger and bigger and more specialized.  Picture source :  https://www.omise.co/the-evolution-of-whales-and-software As you may see in the picture above, mammals were mostly small in the first picture. They became bigger, and ancestors of the whales looked quite dog like.  In the case of the ancestors whales, animals like Pakicetus eventually took to the water to escape predators and also to eat their favored food. In this way, Pakicet

I know that this may be late by a day but I wanted to celebrate a very special post on a very special day- World Wildlife day on the 3rd of march! So, I'm going to start writing a three-part explained story the History Of Life On Earth.  Each part is going to explain an Era in the Earth's History which had life. Archean and Proterozoic (Life Before Paleozoic Era) Life didn't only start in the Paleozoic Era, it started way before, 3.5 billon years ago. I am going to explain that life in this section and then move to the Paleozoic. Now, Paleozoic is an era, which is the second-largest unit we use in the geological timeline.  But the largest is eon, which there are 4 of- Hadean (with no life), Archean (where life started), Proterozoic (where life continued), Phanerozoic (where life evolved and diversified).  So, you may have noticed that life s

Majungasaurus   crenatissimus is a species of carnivorous abelisaurid theropod dinosaur which lived during the late Cretaceous Period 70 to 66 mya (million years ago), in Madagascar. It was an abelisaur and possessed many common traits of Abelisaurids. It had a boxy head and two short arms which barely had a forearm. The animal was covered by osteoderms on its back to its tail. Majungasaurus had one horn on its forehead, distinguishing it from other members of its family. Its legs were short. Its skull was much wider than other abelisaurs. They had more teeth than most abelisaurs. Picture Source -  https://dinoanimals.com/dinosaurs/majungasaurus-the-king-of-madagascar/ It grew to legnths of 5.5 meters - 7 meters.  This theropod ate meat and its diet mostly consisted of sauropods and was also a cannibal. This animal was an apex predator. Its teeth were in short crown shapes. It may have mostly preyed on Rapetosaurus. Their nasal bones were fused and were most likely covered by keratin.

  Picture Source :  https://www.researchgate.net/figure/Principle-of-Adaptive-Convergence-or-Convergent-Evolution-Represented-by-Fish-Reptile_fig80_333773772 Introduction This Post is about Convergent Evolution, why it exists and why it is important. The above picture shows animals which look alike and certainly have similar adaptations but are of different origin and don't share a common ancestor. This will be explained later on in the post alongside other intriguing and wonderful occurrences of this beautiful phenomenon. What Is Convergent Evolution? Convergent Evolution when two creatures in a two or more very different groups adapt to certain environment similarly.  To put it simply, it's like when you copy someone's homework but make it different so your teacher doesn't suspect anything. Homework being ecosystem, the students being organisms and homework meaning body-plan. When an animal is placed in a habitat, it has to adapt to the conditions of that habitat to s

  Picture source -  https://a-z-animals.com/blog/reindeer-in-the-arctic-how-do-they-survive/ Introduction Merry Christmas! This post is all about reindeer, known by pop culture as the animals that help Santa get around the world. Christmas is right around the corner.  Let's dive right in. Reindeer Reindeer are also known as caribou. They are a type of deer in the genus Rangifer. Live in Northern North America and Northern Eurasia. They have large antlers placed on their head and most are on the larger side of deer. Reindeer Habitat Reindeer are found in the Tundra and Taiga regions of Alaska, Canada,  Northern  Scandinavia and Northern Russia. Reindeer Diet They eat grass, lichens, and leaves of certain trees. Reindeer Adaptations Reindeer have evolved to change their body seasonally to improve metabolic efficiency with changing weather. For example, in the Winter months, Reindeer turn their primary food source to lichens as other plant material doesn't grow well and lichens ar
