The dinosaur extinction event wasn't even that bad. The Great Dying was the worst. Nearly wiped all life out on Earth. The horseshoe crab survived. Up to 96% of all marine species and around 70% of terrestrial species died. https://youtu.be/CUQl5Acrc7U

There have been five mass extinction events in Earth’s history. These are called the "Big Five" for obvious reasons. All of the "Big Five" were caused by some combination of rapid and dramatic changes in climate, combined with significant changes in the composition of environments on land or in the ocean. - End Ordovician (444 million years ago; mya); Intense glacial and interglacial periods created large swings in sea levels and moved shorelines dramatically. Tectonic uplift of the Appalachian mountains created lots of weathering, sequestration of CO2 and with it, changes in climate and ocean chemistry. 86% of species lost. - Late Devonian (360 mya); Rapid growth and diversification of land plants generated rapid and severe global cooling. 75% of species lost. - End Permian (250 mya); Intense volcanic activity in Siberia. This caused global warming. Elevated CO2 and sulphur (H2S) levels from volcanoes caused ocean acidification, acid rain, and other changes in ocean and land chemistry. 96% of species lost. - End Triassic (200 mya); Underwater volcanic activity in the Central Atlantic Magmatic Province (CAMP) caused global warming, and a dramatic change in chemistry composition in the oceans. 80% of species lost. - End Cretaceous (65 mya); Asteroid impact in Yucatán, Mexico. This caused global cataclysm and rapid cooling. Some changes may have already pre-dated this asteroid, with intense volcanic activity and tectonic uplift. 76% of species lost.

"Scientists believe they have unraveled one of geology's most enduring mysteries about how the Earth's continental crust was built, and they say it happened in a relative blink of an eye. According to Alexander Cruden, associate professor of geology at the University of Toronto and second author of the paper to appear in the Dec. 6 issue of Nature, the way that granite forms - a rock that makes up about 70 to 80 per cent of the Earth's continental crust - is not the sluggish, multi-million year process that scientists previously believed. In fact, Cruden and his co-authors argue that the process occurs in rapid, dynamic and possibly catastrophic events that take between 1,000 and 100,000 years, depending on the size of the granite intrusion. And that's changing how scientists look at the formation of the Earth's continents."

I genuinely wonder how widely that's accepted? It'd actually be quite interesting, if true.

yaasshat @yaasshat Not a whole lot, dude was basically ignored and the rest of researchers just moved on, unwilling to entertain him

Ah, I love the branches of science in the air. I love learning about anthropology, virology, anatomy, radiology, genetics, physiology, physics, meteorology, geology, planetary science, astrophysics, and etc.

"I mean what about noah and his fsmily what did they eat? People always wanna get technical well lets talk about that." Prob the dinosaurs. Jk. Seriously though, if we could place the time, the location, that would tell us more about what they could have ate, what animals were aboard, etc.
