I have a really good question. Could it be possible for complex life to have existed in the Precambrian? I'm aware that only the fossilized remains of bacteria have been discovered from that time p...
First things first, a little backstory: Sometime between the Paleocene and Eocene epochs, there was a mysterious, sudden, dramatic rise in global temperature. This moment in time was known as the...
After 150 million years, the most successful empire in the history of Planet Earth finally collapsed 66 million years ago. A five-mile-wide space bomb--there's still disagreement as to whether it ...
Atlantis is real. It's just that there's more than one of them, and none of them are actually called "Atlantis". Instead, they consist from the Kerguelen Plateau in the Indian Ocean to Zealandia,...
Here is all you need to know about the creodonts: They were a group of carnivorous mammals that, despite having carnassials, had no relation to Carnivora. They were a global force, occupying terr...
I am working on a species that ressembles humans beings and that, although slightly engineered in the sense that the evolutionary leaps are aided by genetic modification, they are left to go throug...
In recent years, the search for the origins of life is becoming complex. It turns out that oxygen is NOT a requirement for multicellular life to thrive. As stated in this BBC article, poriferans ...
So a friend is working on a worldbuilding/rpg project and I'm "beta-testing". He drew up an earth-like map and set the players start locations. Then I ask him about fauna. Will it be modern earth? ...
We've found all sorts of interesting stuff in arctic ice & permafrost around the world. Bacteria & the like far older than the more media friendly mammoth specimens have been found, living...
Premise Inhabiting my earth-like world will be humanoid beings that have a skin tone that is as dark as Vantablack. Let's assume these human-like beings share the same ancestry as humans and we ca...
Premise I'm creating a pre-history world to attempt to demonstrate an alternative sequence of events. I would like natural forces to somehow make natural selection view intelligence/technology as ...
Let's start with a little backstory--our planet underwent an impact-coalescence cycle only once, 4.5 billion years ago, when a Mars-sized object named Theia destroyed the infant Earth in a glancing...
I was reading this question earlier today. It asks about the characteristics of global winds in a modern-day earth with Eocene-like temperatures. I'm here to ask about other kinds of weather in the...
So many millions of years ago their was a lobe finned lung fish named tiktaalik that led to the evolution of all tetrapods and the diversity they hold today. And I wanna do that again, but instead ...
An underwater stone age tribe of merfolk captured 2 baby whales and killed the adult beast for meat. My sea people would like to tame the young whales and use them as transport when the babies rea...
For a story I require an intelligent [drepanosaur]. But to work with the plot the creature needs to still have traits that don't mix well with classical vertebrate evolution of intelligence. Requi...
In my world there is a neolithic civilization of people who inhabit earthen trenches. The people first soften the earth with ... fluids ... and dig out 6 - 12 foot deep trench systems that extend o...
From 359 to 298 million years ago, the "Carboniferous Coal Swamps" dominated the continents. It was the Carboniferous coal itself that sparked one of the greatest watersheds in human history--th...
It has become accepted knowledge that the planet Earth was birthed via a swirling cloud of dust and gravel clumping into larger and larger pieces of rock. It began 4.54 billion years ago, and 100 ...
Here are some lists of North American and South American megafauna that went extinct during the Quaternary. In Eurasia, many species of large mammal were domesticated, most particularly the 'big 4...
In a world where man entered North and South America without causing a mass extinction, all of the paleofauna which became extinct ~10,000 BC in the Americas are still around. There are several fam...
The BBC in the UK are currently screening a archaeology series exploring the idea that the Neolithic peoples in the Orkney Isles (North of Scotland) were the cultural capital of the British Isles. ...
From 5.96 to 5.33 million years ago, disaster struck the Mediterranean Sea. A tectonic snag turned this... ...into something like this. In this alternate scenario, the sea separating modern ...
Five million years ago, the warm Miocene gradually descended into the cool Pliocene before dropping into the frigid Pleistocene. Such a change in temperature was so gradual that life went on withou...
