Cenomanian-Turonian boundary event
Alright, let's imagine you're a little kid exploring the Earth a long, long time ago, about 90 million years ago. At this time, dinosaurs were roaming on the land and lots of different creatures were living in the oceans.
Now, scientists have a way of dividing time into different parts called "ages." One of these ages is called the Cenomanian. It was a time when a different group of dinosaurs called "sauropods" were the biggest and tallest creatures on the planet. They had long necks and ate lots of plants.
But, something very interesting happened during this time. There was a big event called the Cenomanian-Turonian boundary event. This event marked the end of the Cenomanian age and the beginning of the Turonian age. It was like a turning point in Earth's history.
So, what actually happened during this event? Well, it was a time of great changes in the oceans. You know how the Earth has big pieces of land and big pieces of water, right? Well, during this event, there was a big change in the balance between land and water.
Some creatures in the oceans called "plankton" were going through a tough time. Plankton are tiny plants and animals that float in the water and are an important part of the ocean's ecosystem. They were having a hard time because the amount of food available to them suddenly decreased. It was like having less cookies to eat, which made them very sad.
This decrease in plankton food had a big impact on other creatures in the oceans. Some bigger animals like fish and marine reptiles that relied on the plankton as food had to struggle to find enough to eat. It was like if your favorite food suddenly disappeared from the grocery store!
Now, you might ask, "Why did the plankton food decrease?" Well, scientists believe that some changes in the Earth's climate caused this. The climate is like the weather but over a long period of time. During the Cenomanian-Turonian boundary event, the Earth became warmer, and the oceans became more acidic.
This warmer and more acidic environment created problems for the plankton. They couldn't survive very well in these conditions, and their numbers decreased. As a result, the whole food chain in the oceans got disrupted, and many creatures had to find new sources of food or even move to different areas.
So, the Cenomanian-Turonian boundary event was a time when the Earth's climate changed, and it had big effects on the creatures living in the oceans. It was a time of struggle and adaptation for many marine animals, just like when you have to adjust to changes in your life, like moving to a new home or starting a new school.
Scientists study this event to understand more about how the Earth's climate can impact different ecosystems and the creatures living in them. It helps them piece together the puzzle of Earth's history and how life has evolved over time. Pretty cool, isn't it?
