Hey kids! Welcome to another brilliant article from KidsCast! Have you ever wondered that before us, dogs, cats, lions, cows, and all the animals, which was the World's First Animal? Well, today, we are here to know about it! So let us begin! 

About the World's First Animal: 


The world's first animal was Dickinsonia. Dickinsonia is one of the first animals from marine life, and the picture above is not Dickinsonia but the cast of its fossil. It is now extinct, but we can still trace back to our beginning to this animal. Its primary type of animal is still unknown, but many scientists say it belongs to the group of fungi. Some scientists also say that it belongs to a kind of animal kingdom that is now extinct (or no more living). 

Dickinsonia used to exist in the parts of the world which are now Australia, China, India, Russia, and Ukraine. It was a soft-bodied creature that moved along the sea bed and used to eat microbes and algae. 

Its Structure:



Fossils of Dickinsonia are in the form of imprints and casts, on sandstone beds. These specimens can be as small as a few millimeters and can also be as long as one metre or so, being a few millimetres thick. The shape of these fossil casts is mostly oval, and just like a leaf's structure, it seems like it also has many branch structures. It is merely symmetrical and has many branches each of them being an isomer, and has a Head. It can also be very circular or sometimes even the shape of an egg. 

Discovery of Dickinsonia: 


Dickinsonia was first discovered in South Australia, by Reg Sprigg, an Australian geologist, and conservationist. He named the name Dickinsonia after Ben Dickinson, who was also an Australian geologist. Then additional discoveries were made in Russia, Ukraine, and India. 

What is Unknown? 
Even though we know about Dickinsonia and where it was found, we still have many things about it which are unknown. For example, we don't know its detailed definition, functions, and history. Scientists keep researching on this, and surely one day, we will find more information about it! 

So, kids, this was all we know about the world's first animal. We hope you enjoyed this article! Stay tuned for more articles, and till then, Happy Learning!

So let us begin! WHAT IS THE BERMUDA TRIANGLE?? For those of you who don't know what the Bermuda Triangle, let me tell you. The Bermuda Triangle is a loosely defined area in the western part of the North Atlantic ocean where a number of ships and planes have gone missing under mysterious circumstances. It also vaguely looks like a triangle with its vertices being Florida, Bermuda and Puerto Rico. USS Cyclops' Disappearance USS CYCLOPS was the second of four Proteus-class colliers or ships we can say, built for the United States Navy several years before World War. The loss of the ship and 306 crew memebers without a trace, remains to be America's greatest loss of life in their Naval history without any combat. It was thought to be sunken by a German Raider but the German Government denied any

The Early Explorers: Our story begins with the early explorers who came to the land that is now the United States. These adventurous individuals, like C hristopher Columbus, Amerigo Vespucci, and John Cabo t, sailed across the vast oceans to discover new lands. They were looking for a shorter route to Asia but stumbled upon the vast continent of North America instead. So it was by accident that they reached North America.

Microorganisms, often too tiny to be seen without a special tool called a microscope, are remarkable living beings that are all around us. These tiny creatures, also known as microbes, have a big impact on our world. While microbes help us in many things, such as decomposition, breaking down things, digestion and making some foods, some other microbes also are dangerous to us. In this article, we will embark on an exciting journey to discover the fascinating world of microorganisms, exploring who they are, their different types, and even some surprising facts that make them both friends and foes. What are Microorganisms? Microorganisms, or microbes for short, are living things that are so small that you can't see them with just your eyes – you need a microscope. They're basically very small and very tiny creatures which you cannot see just by your eyes. They come in different shapes and sizes and are incredibly important, despite being super tiny. Microbes include bacteria, v
