Earth is overdue a mass extinction event by 30MILLION years… after the last apocalyptic catastrophe killed the dinosaurs

 Doomsday scenarios are usually the subject of Hollywood blockbusters.

But experts believe they are more scientific fact than science fiction – with Earth overdue a mass extinction event for more than 30million years.

They have worked out that catastrophic global incidents come roughly every 27million years.


And with the last mass extinction 66million years ago – when dinosaurs were wiped out by an asteroid or comet – they reckon Earth could be on borrowed time.

Catastrophic events such as meteor strikes and eruptions can follow a cycle.

With new statistical analysis, US researchers concluded extinction comet showers occur every 26 to 30million years when they pass through the galaxy.

If they hit Earth, the cataclysmic impacts could create widespread dark and cold, wildfires, acid rain and ozone depletion.

These would potentially kill off land and marine life.


The scientists also found all eight of the coinciding mass extinctions on land and in the oceans matched times of flood-basalt eruptions – where an enormous amount of lava flows on to the Earth’s surface. This would create lethal greenhouse heating and less oxygen in the ocean.

Any threat is down to how our planet orbits the Milky Way, they say. The study’s author, Professor Michael Rampino from New York University’s Department of Biology, said: ‘It seems that large-body impacts and the pulses of internal Earth activity that create flood-basalt volcanism may be marching to the same 27million-year drumbeat as the extinctions, perhaps paced by our orbit in the galaxy.

‘These new findings of coinciding, sudden mass extinctions on land and in the oceans, and of the common 26 to 27million-year cycle, lend credence to the idea of periodic global catastrophic events as the triggers for extinctions.

‘In fact, three of the mass annihilations of species on land and in the sea are already known to have occurred at the same times as the three largest impacts of the last 250million years, each capable of causing a global disaster and resulting mass extinctions.

‘The global mass extinctions were apparently caused by the largest cataclysmic impacts and massive volcanism, perhaps sometimes working in concert.’

The findings are published in the journal Historical Biology.

  3. Is that a real a dinosaur?

  4. Recent mass extinction events;

    "Venus Event" - (est.) 1500 BC
    "Noah Event" - (est.) 12,000 BC

    Much proof exists that dinosaurs survived locally the object which smashed into Earth (est.) 65 million years ago.

  5. We had a close call about 300,000 years ago when a star in the Gemini constellation went supernova, releasing a powerful gamma ray burst and producing the Geminga supernova remnant, which was one of the first radio pulsars discovered by early radio astronomers. At the time of the explosion, it was about 60 parsecs from earth. If it were any closer, maybe 20 parsecs or less, the gamma rays would have killed all life on earth and stripped away much of earth's atmosphere, rendering the earth a dead planet. Scientists speculate that at the worst, our ancestors may have gotten a mild sunburn and/or experienced a higher than normal rate of skin cancers for a couple of generations.

  6. What about the mass extinction that happened about 12,500 years ago? All the megafauna in N America disappeared. If they aren't including that then what is the definition of a mass extinction?
