8 Largest Prehistoric Crocodiles Ever

Sarcosuchus
Sarcosuchus was one of the largest crocodiles ever lived in history (about 12 meters long, or 40 ft). They lived in the Early Cretaceous in the Sahara Desert some 110 million years ago before camels and Tusken Raiders became the dominant species. In the Cretaceous, the Sahara was once filled with waterways and lush jungles. Massive dinosaurs like Paralititan were hunted by predators like Carcharodontosaurus. In the water, however, Sarcosuchus would have reigned unchallenged. Its name means "Flesh Crocodile Emperor". S. imperator probably had a generalized diet similar to that of the Nile crocodile. A diet that would have included large terrestrial prey such as the abundant dinosaurs that lived in the same region. Photo: photos-albums.com

In the prehistoric ages, some animals were much bigger than today’s counterparts – including crocodiles. Crocodiles have long been some of the most feared and respected creatures on the planet, and their prehistoric ancestors were no different. Some of the largest and most terrifying crocodiles to ever exist walked the Earth millions of years ago, making even the largest modern crocodile look like a mere lizard by comparison. From the massive Deinosuchus to the impressive Sarcosuchus imperator, this article will explore eight of the largest and most impressive prehistoric crocodiles ever discovered, giving readers a glimpse into a long-lost world of giant reptiles and ferocious predators.

How fast does Earth move in Space? [Exploring the Mind-Bending Speed of Earth’s Journey]

As we go about our daily lives, it’s easy to forget that we’re all hurtling through space at incredible speeds. Earth is constantly in motion, rotating on its axis and orbiting around the sun. In fact, we’re all living in a fast-moving spacecraft. But just how fast is our planet moving? What’s the speed of Earth in space?

The answer is surprisingly complex, and the exact speed varies depending on the reference point. In this article, we’ll explore the different ways to measure Earth’s speed, from its rotation speed and its orbital velocity around the sun to the Sun’s movement around the center of the Milky Way galaxy, and gain a new appreciation for the incredible speed at which we’re all traveling.

Here’s why the sky and the Sun are reddish at sunrise and sunset

Sunset at the Istanbul Technical University
Rayleigh scattering causes the blue color of the daytime sky and the reddening of the Sun at sunset. Image: Sunset at the Istanbul Technical University campus. I took this photo on February 10, 2023.

The sky and the Sun appear in different colors (reddish or orange) during sunrise and sunset because of the way that light travels through the Earth’s atmosphere.

During the day, the Sun appears white because its light is composed of all the colors of the spectrum. As the Sun gets closer to the horizon during sunrise and sunset, its light has to travel through more of the Earth’s atmosphere before it reaches our eyes. This causes the shorter, bluer wavelengths of light to scatter more, leaving the longer, redder wavelengths to dominate.

These Photos Show the Incredible Power of Earthquakes

Railway tracks bent more than 3 meters (10 feet) during Turkey earthquakes (2023)
During the earthquakes that occurred in Turkey on February 6, 2023, the land moved more than 3 meters (10 feet) on the fault lines in some places. This photo shows the incredible power of earthquakes. Railway tracks bent more than 3 meters (10 feet).

On the early morning of February 6, 2023, two consecutive devastating earthquakes (with magnitudes of 7.8 and 7.7 on the Richter scale, just nine hours apart in the same area) hit Turkey and Syria, killing tens of thousands and injuring hundreds of thousands of people.

How long do great white sharks live?

Great white sharks (Carcharodon carcharias) can live for a very long time, with an estimated lifespan of 70 years or more. However, it is difficult to determine the exact lifespan of the great whites because they are not easy to study in the wild. And they cannot be kept in captivity, they start to weaken when they are put in a pool or a tank – even a big one. They constantly run into the glass until they get exhausted and die.

Elephants are wonderful creatures for many reasons! They are intelligent and social animals that form close bonds with one another and live in complex family groups. They are also highly adaptable and can survive in a variety of different habitats, from the savannas of Africa to the rainforests of Asia. In addition, they play important roles in their ecosystems as keystone species, meaning that their presence can have a significant impact on the overall health and balance of their habitats. Finally, elephants have unique and fascinating biology, including their large size, long lifespan, and remarkable memory.

If every people jumped into the ocean at once, how much would the sea level rise?

If every person on Earth were to jump into the ocean at once, the sea level would rise only about 1.3 micrometers
If every person on Earth were to jump into the ocean at once, the sea level would rise only about 1.3 micrometers. For comparison, a human hair ranges in thickness from 17 to 181 micrometers. Image source: Deposit Photos

If every people on Earth were to jump into the ocean at once, the sea level would not rise significantly. The total volume of water added to the oceans by all the people on Earth jumping into them would be relatively small compared to the total volume of the oceans, which is about 1.35 billion cubic kilometers (about 320 million cubic miles).
