The last time the world was ending, two cataclysms aligned. On one side of the planet, a wayward asteroid dropped like a cartoon anvil, punching through the edge of the Yucatan Peninsula and penetrating deep into Earth’s crust. Around the same time — 66 million years ago — a million cubic kilometers of lava were in the process of bubbling up to the surface, releasing climate-altering carbon dioxide and sulfur into the atmosphere and forming what would become the Deccan Traps of modern-day India.

Rock layers around the world show what happened next. No dinosaurs besides the birds made it out. Neither did the squidlike ammonites that curled like rams’ horns, or marine reptiles including the plesiosaurs (Loch Ness conspiracies notwithstanding). But because of the close timing of the asteroid and the volcanism, geologists have spent years staking out increasingly acrimonious positions on which one deserves the blame for the ensuing carnage. In 2018, The Atlantic called the debate “The Nastiest Feud in Science.”

A Rapid End Strikes the Dinosaur Extinction Debate

The paleontologist Pincelli Hull has nailed down the timing and speed of the extinction that killed off the dinosaurs — details that carry ominous warnings for today.

More conjecture that be good fiction, but very bad Science.

What do you know about science? You couldn't even wrap your head around a high-level conversation about the accuracy of our interplanetary maths..

A massive asteroid hitting one side of the earth, and massive volcanic eruptions the other side of the earth...
How difficult can it be to link these two events together?
The mantle of the earth ain't that thick. smack a balloon filled with water and see the ripplles. i can imagine that is what the earth looked like.
So a 3 mile chunk of rock slamming into it will shift stuff around, earthquakes and volcanoes will go bonkers. surely that is logical to think they belong together. What am i missing?

That thumb-sucked theories that be pure speculation is not Science.

In ToE it does not work that way, branches of species continue to exist until becoming extinct, they don't all turn into something else.

It could've happened over millions of years, considering the dinos have been gone for 66 million

True, my understanding was just that evolution is not driven, i.e. there is not a definite outcome to be expected from mutations, thus evolving into birds is not a given, just a happenchance and the probability of similar mutations (actually permutation of mutations) is extremely unlikely.

You're missing the fact that it's almost impossible to deduce that these 2 events actually happened in a short space of time,carbon dating and other methods always have several thousand years of margin for error at best.

The precision is just not there to say this happened at exactly the same year/month/day.We just know it was around 66 Million years ago probably give or take several thousand years regardless of the accuracy of your calculations!

You'd think that, but there are many different species that look or act similarily but aren't even related. Saber tooth tigers were marsupials but looked and filled the role of big cats.
