And Rodinia was just wasted. No dinosaurs, no railway networks, nothing.

Pangaea was wasted on the dinosaurs. Imagine the railway network.

Antarctica’s Hidden Alps: Scientists Finally Solve 500-Million-Year-Old Mountain Mystery

For over half a century, a vast mountain range has remained hidden beneath Antarctica’s frozen heart. Now, scientists have finally cracked the geological code behind the Gamburtsev Subglacial Mountains—a Himalayan-scale formation entombed beneath kilometers of ice for over 500 million years. The discovery sheds new light on how Earth’s ancient supercontinents formed, why East Antarctica has…

Not enough supercontinents in fantasy

SpaceTime Series 27 Episode 133 *Earth's Mantle: Two Distinct Domains Revealed Groundbreaking research has unveiled that the Earth's mantle is composed of two distinct and separate types of materials, forming independent African and Pacific domains. This discovery, published in Nature Geoscience, challenges previous assumptions of a chemically uniform mantle. The study highlights how these domains have been shaped by the formation and breakup of supercontinents over the past 700 million years, revealing the Earth has two chemically distinct hemispheres. *China's Ambitious Lunar Plans China is accelerating its space ambitions, aiming to send its first taikonauts to the moon by 2030. The China Manned Space Agency plans to use its new Long March 10 rocket to transport taikonauts and a lunar lander to the moon's surface. This mission marks a significant step in China's lunar exploration, with plans to establish a joint base with Russia on the lunar surface by the early 2030s. *NASA's SpaceX Crew 8 Returns to Earth After a seven-month mission aboard the International Space Station, NASA's SpaceX Crew 8 has safely returned to Earth. During their mission, the crew conducted over 200 scientific investigations, including studies on space-based manufacturing, gene editing in Space environments, and plant growth in high radiation settings. These experiments aim to advance our understanding of long-duration Space missions and their potential applications. The Science Report Australia's climate continues to change with more extreme heat events and extended fire seasons. The latest State of the Climate Report highlights ongoing shifts in weather patterns, rising sea levels, and increasing temperatures. Meanwhile, a new study suggests vitamin K2 could help reduce night-time leg cramps, and the Australian Defence Force receives new Black Hawk helicopters amidst regional tensions. www.spacetimewithstuartgary.com www.bitesz.com 🌏 Get Our Exclusive NordVPN deal here ➼ www.bitesz.com/nordvpn.

I love that Westeros is in the east. This is so great lol

One of my favorite hobbies is thinking about the fucked up implications of this fantasy world map my parents got me for christmas

Mammals will most likely be wiped from the face of the Earth by our planet's next supercontinent, a new study has revealed.  By modeling the heat tolerance of mammals alongside Earth's climatic conditions 250 million years into the future, scientists have discovered that the formation of the most probable next supercontinent — called Pangaea Ultima — will bring about the likely extinction of our animal order. The researchers made the prediction using a climate model that factored in the changes to land surface temperature of a new supercontinent; alongside increases to the intensity of the sun's radiation and carbon dioxide in the atmosphere. The study was published Sept. 25 in the journal Nature Geoscience. "A supercontinent seemingly creates conditions that more easily lead to mass extinction," first-author Alexander Farnsworth, a climatologist at the University of Bristol in the U.K. told Live Science. "[Supercontinent formation] has coincided with four of the last five mass extinctions in the geologic past."

2 Billion years of Tectonic History for Jom'Gol !!!!

After simulating the plate tectonics for an excruciating 2.5 billion years (not irl time, but might as well have been), I made this crude animation of the previous 2.5 billion years of tectonic history!

Although very crude, the simple borders represent landmasses, the scratchy lines represent orogeny or mountain ranges. Every frame is 50 million years (date listed at the top). (also little sounds in there too .w.)

I intend to add an additional space in between each frame for every 25 million years, then probably color them with a basic topographic map. Until then !!! I continue on !!!!

[kudzucataclysm]

me: heh i wonder what the continents/earth will look like in one BILLION years heh…

the internet: plate tectonics will cease to exist because of the hardening of earth’s liquid outer core which will in fact destroy earth’s magnetic field which’ll cause the evaporation of the atmosphere and presumably end all life on earth. also the ocean will probably not exist anymore

personal favorite geologic time?

I mean, the Hadean eon was pretty hot.

But I have a soft spot for Devonian too! Had some real neat things that became fossils. But I think the mesoproterozoic era is my favorite, JUST for the formation of what would become the appalachian mountains. I respect my elders.

[alwaysoutofpaper]

i've had this sitting around for months now, and i recently learned how absolutely ass this land formation probably is. i still like it, but i'm probably going to scrap it. until I make a better one, here's the original map for the hae planet :)

Gondwana was the great southern landmass that formed as a result of the division of a much larger supercontinent known as Pangea about 250 million years ago. This Gondwanan supercontinent consisted of present day landmasses: Africa, South America, India, Madagascar, Australia and New Zealand. The other section of Pangea, known as Laurasia, comprised what are now Europe, Asia and North America.

The Neoarchean era began 2.8 billion years ago and lasted until 2.5 billion years ago. The cyanobacteria empire continued to evolve and diversify, even adapting to life on land. It is thought at this time that the land would actually start to turn green, not from plants yet, but rather the massive microbial ecosystems pumping oxygen into the atmosphere. During this era we would also see the planet's first supercontinent, named Kenorland

Continuation of this

BEHOLD, MY CREATION

Also, croc-descendants and dinosaurs still exist because of course they do. And specially those commonly mentioned organisms which are older than dinosaurs and still exist

having a normal one on shit that doesnt even matter in the game btw
