  Yup, that’s what I’ve said all along. Human race is an accident.

  Rather, the human race is contingent.

  After it hit the dinosaurs took 33,000 years to completely die off. There’s a bunch of non science, careerism, egos & a cult like following of Alvarez who was a abusive bully - going on with this episode.

  **Did volcanic eruptions help kill off the dinosaurs?**
  .
  Twin studies find massive lava flows occurred around the time of a cataclysmic asteroid impact
  .
  “But the asteroid wasn’t the only catastrophe to wallop the planet around this time. Across what is India today, countless volcanic seams opened in the ground, releasing a flood of lava resembling last year’s eruptions in Hawaii—except across an area the size of Texas. Over the course of 1 million years, the greenhouse gases from these eruptions could have raised global temperatures and poisoned the oceans, leaving life in a perilous state before the asteroid impact.

  The timing of these eruptions, called the Deccan Traps, has remained uncertain, however. And scientists such as Princeton University’s Gerta Keller have acrimoniously debated how much of a role they played in wiping out 60% of all the animal and plant species on Earth, including most of the dinosaurs.”
  .
  https://www.science.org/content/article/did-volcanic-eruptions-help-kill-dinosaurs
  .
  Other extinctions, mass & lesser were caused by volcanic traps altering the atmosphere by burning buried carbon which releases greenhouse gasses–> Global warming—>run away climate change & ocean acidification & worse things like a Canfield ocean.

  Theses hot house extinctions are most common. If there was no meteor the Deccan traps would have caused another hothouse mass extinction.
  .
  The research for a newly discovered hothouse mass extinction was published in 2020. It looks like the other hothouse mass extinctions & it paved the way for the dinosaurs.
  .
  Currently the rate at which the humans are emitting greenhouse gasses is far & away faster than any know volcanic traps have. It’s thought that the rate during the Permian mass extinction (worst one so far) took thousands to tens of thousands of years.
  Humans have emitted around half of the full amount of greenhouse gasses that caused the Permian, only the humans have done that in just 270 years. The earth has never experienced greenhouse gas emissions at that speed. To call it unprecedented would be the understatement of all time. The humans have caused ‘Runaway climate change’ so the only impact their behaviour can have is on the speed the hammer will fall. 2022 was a record for amount of GHG’s in a single year - Congrats humans another record!!. This simply makes the hammer fall faster. No truly sapient species would be in this pickle. In just the last 2 months there’s been hundreds climate change jacked disaster records smashed and they will be broken again & again - we’ll soon stop measuring.

  “After it hit the dinosaurs took 33,000 years to completely die off.”

  No, that’s false. They never did completely die off. Ever hear of birds? Those feathered, chirruping chaps, flying all over the place? There are a great many dinosaurs nesting in the Caesarean garden, right at this moment, 65 million yrs later.

  Dinosaurs survived. And they didn’t even have an internet.

  Thanks for sharing. Some paleontologists believe that dinosaurs were already in decline, there was a large decrease in diversity, compared the Triassic and Jurassic, which is never good for any species evolution. With the earth shifting around, they believe animals migrated, bringing diseases to susceptible populations which further caused declines. The asteroid was just the final nail in the coffin.
  Its an interesting theory, and hope to hear more of it.

  caesar963 if the dinosaurs had hair, I doubt they would waste their time splitting them in a sad attempt to look clever.

  How many of today’s dino-bird spices were around when the impact & Deccan traps happened?

  Birds evolved from dinosaurs called theropods. I don’t think there’s much chance sparrows will be staring in the next Jurassic Park movie.

  While ‘technically’ true, it’s best use has been as a marketing gimmick that’s reignited interest in dinosaurs. Millions of school kids on field trips going through the turnstiles at museums to see the new feather clad Dino exhibition and dino fans of all ages have forked out gazillions for new feather clad merchandise.

  **How Tycoons Created the Dinosaur

  The story of dinosaurs is also the story of capitalism.**

  “For one thing, dinosaurs cannot be experimented upon. Instead, scientists have to interpret the fossil record, which is spotty at best.”

  “..paleontologists had to work hard to assemble dinosaurs into something that resembled real, live animals. In doing so, they relied not only on the available evidence, but also on inference, judgment, and their imagination.”

  “More recently, many museums have completely overhauled their aging dinosaur displays yet again, to better reflect contemporary views of these creatures as bird-like, active, and fast-moving, with complex social structures.”

  “attempt to look clever” - Not something you ever need to concern yourself with, ap, ol’ chap.
  “dinosaurs had hair” - Feathers. Those gents had feathers.

  Less of your bird-denialism now, I won’t hear of it.
  “How many of today’s dino-bird spices” - Not a pertinent question, as it turns out, whether applied to species or delectable spices. Evolution, u c.
  “sparrows will be staring in the next Jurassic Park movie.” - Now that’s legitimately sad. Stark staring semi-starlet sparrows.

  “While ‘technically’ true” - Now see, THIS is where you habitually stumble (not “technically” stumble - that’s too slippery). The whole binary truth/falsehood thing always tripping you for 6.

  “How Tycoons Created the Dinosaur…story of dinosaurs is story of capitalism” - Oy. That old extinct & failed ideological discourse. “Capitalism this! Capitalism that!” Or, to aid our frozen ideological deliberations: East Germany this, West Germany that; North Korea this, South Korea that.

  “have to interpret fossil record, which is spotty at best.” - Well, it is a damned long time ago, so all that evolving scholarship palaver is unavoidable, and can’t remain comfortingly static. Or frozen in amber even.

  Hopefully this is the last days of anything written about Dinosaurs by one Riley Black. Suitable for ages 7 thru 13 only. And the 13 year olds will probably laugh at its lameness.
