Intergalactic Law states that first contact can not be made until an intelligent species successfully staves off an extinction event. Earth, having just destroyed an asteroid passing that criteria, is immediately greeted by millions of alien species there to celebrate, and party hard
When a 6-mile-wide asteroid struck Earth 66 million years ago, it wreaked havoc,
showering the planet in hot clouds of sulfur and ash, completely
changing the climate and wiping about 75% of the species on Earth at the
time. The impact is what likely caused the dinosaurs to go extinct.
We don’t know a lot about this cataclysmic event or how life managed to make a comeback.
120 million year old fossil Brazilian spider. Check out the detail on this preservation.
A spider that lived at the time of the dinosaurs. This ~120 million year-old fossil spider in limestone has been replaced by the mineral goethite (iron oxide-hydroxide). Spiders go back more than 250 million years and their diversity does not appear to have been affected by the great extinction event that wiped out the dinosaurs and other critters. Today, spiders are the most abundant predators on land. Perhaps during the time of dinosaurs as well?

Back in April,
researchers first uncovered evidence that a pair of stars about 300
light-years from Earth exploded millions of years ago. Now, follow-up research
suggests one of those explosions — a huge supernova — may have been
powerful enough to trigger a “minor mass extinction” on Earth.
The extinction likely occurred 2.59 million years ago, at
the end of the Pliocene age. The explosion may have blasted blue light into Earth’s sky for weeks, but that’s not what killed the animals.
Study reveals mass extinction event 35 million years ago
Biologists at The Australian National University (ANU) have found the first evidence of mass extinction of Australian animals caused by a dramatic drop in global temperatures 35 million years ago.
This period of intense and rapid climate change occurred at the same time when Australia separated from Antarctica.
Lead researcher ANU PhD student Ian Brennan said the team detected the mass extinction of pygopodoid geckos by using molecular evolutionary methods to examine fossil records.
“The dramatic shift to colder and drier climates likely resulted in rapidly changing Australian habitats, which hugely impacted the animals that inhabited them,” said Mr Brennan from the ANU Research School of Biology.
“Our research provides evidence that rapid shifts in climate may have profound and long-lasting effects on global biodiversity.”
Mr Brennan said findings also suggested the emergence and spread of deserts in Australia from about 10 million years ago provided ideal habitat for new pygopodoid gecko species to prosper.
“Our findings suggest that arid regions of Australia have acted as a cradle for geckos, promoting the rich gecko diversity that is found across the continent,” he said.
Co-researcher Dr Paul Oliver said geckos did well in the harsh climates of arid Australia because they avoided the heat by being nocturnal.
“Many desert geckos also have strategies and attributes to avoid water loss, such as having relatively rugged skin and scales,” Dr Oliver from the ANU Research School of Biology.
“The clear scale over the eye, called a spectacle or brille, is one such example of this, as it helps them avoid water loss from the surface of the eye. But that means they can’t blink, so they have to lick it clean.
“Underwoodisaurus and their relatives Nephrurus have little ‘eyebrows’ that stick out to keep dust and dirt off their eyes, because they’re burrowing species.”
The pygopodoid geckos are a group of about 150 species found across Australia.
I honestly don’t think i’ve ever felt as much rage towards a fictional character as I do towards Ted Faro which I take as a sign of bomb ass writing.
Because like, it wasn’t enough for this dude to cause the literal end of the world and what was probably the largest (and certainly the most devastating) extinction event ever. Literally stripped the atmosphere and killed every living thing.
But that wasn’t enough because Ted Faro is mansplaining and the male ego taken to maximum levels
because this man caused the end of the world and still thought he knew better than the people working on Gaia/Apollo. he took away human history because he thought it wasn’t enough that they had been building fail safes into gaia/apollo. it wasn’t enough that the alphas were working on preventing exactly what Faro was worried about. No he had to go and literally delete every recording of human history and then murder all the alphas because of course he was right and they were going about things wrong
where’s my DLC where I can go back in time and punch him in the face
A Thunderbird is an oversized large bird that has been reported for centuries. Native Americans knew of this creature and speak of it in legends. But as with most legends, there is truth behind it. A wingspan is typically estimated from 8-12 feet from witnesses, of which the first reports came in the late 1800’s. In 1890 it is said that two cowboys shot and killed a large bird that had no feathers, smooth skin and an “alligator head.” This report mostly resembled a Pterodactyl, could the species have survived past its mass extinction event?
On April 10, 1948 three people in Illinois claimed to have seen what they thought was a passenger plane until they noticed its wings were flapping. A few weeks later in Illinois two people saw a giant bird which projected a shadow the size of a plane’s shadow onto the ground. In 1977 in Illinois three boys were playing when a large bird came out of the sky and chased them. It picked one of the boys up and dropped him later after carrying him quite a distance. In 2002, a large bird which “looked like something out of Jurassic Park” was spotted in Anchorage, Alaska. Recently, reports of a giant bird have been seen in Texas.
What is the Thunderbird? Is it real or just a big hoax. Sightings of the creatures are rare, and only happen occasionally. Is it an oversized bird? Or a small family of Pterosaurs that has managed to survive until modern times? The answer lies in the skies, but we may never know.
was invited to be a secret guest in Artbook for FOE (Fancon of extinction) only event at Korea last December. The event has pass so i think its OK to post Many thanks to @kkingkk to letting me participate of this event. you’re so very kind and patient to me and help me through manythings!
there’s a March for Science being organized now and since I missed out on being involved in the Women’s March, I’m going all out for this one
we are in the middle of a sixth mass extinction whether you know it or not, it’s even already named - The Holocene extinction event -
and within 100 years we could be looking at a 99% species loss including ourselves
our children might truly be the last humans if we don’t reverse our damage to the climate and ecosystem within 20 years
all believers of science, everyone who cares about the good of our species and all others, please stand with us - we cannot let the oil companies and climate-deniers control our future
Do Impacts Really Cause Mass Extinctions? | Space News
For decades, many scientists have believed that asteroid bombardments, such as that which is thought to have killed the dinosaurs, occur on our planet at regular intervals of about every 26 million years. A popular theory was that a dim companion star called Nemesis would approach our Sun at 26 million year intervals, inevitably causing mass extinctions on Earth. However, the companion star has never been found, and a new scientific study confirms that such bombardments, if they do occur, are random. But a more fundamental question is, are impacts from space really the cause of extinction level events on our planet?
