The granddaddy of all mass extinctions, this event saw 96% of all marine species and 70% of land vertebrate species kick the evolutionary bucket.

The die off happened in less than a million years (a very short time in geological terms) and the recovery took 5

It’s called the Holocene Extinction — Holocene being the current epoch that began at the end of the last ice age, about 10,000 years ago.

From Earth’s fossil record, we know about Six Great Mass Extinctions:

• The Ordovician-Silurian Extinction occurred about 444 million years ago.

  At the time, all complex organisms lived in the sea. The most common theory is that the onset of an ice age caused the extinction, which wiped out over 100 families of marine life. Many trilobite families bit the dust during this event.

• The Late Devonian Extinction happened 364 million years ago.

  This event saw a major worldwide extinction of coral reefs and the marine life they supported, as well as other groups of animals and plants. Nobody’s sure what caused it, but scientists speculate global cooling and several medium-sized asteroid impacts within a few million years of each other may have been the culprits.

• The Permo-Triassic Extinction occurred 251 million years ago.

    Your Approach Makes a Difference
    Not long ago my wife and I were planning a get-together with some friends and wanted to serve a cheese board after dinner. So, we ventured to a local market to look for some cheeses.We asked for one particular cheese at the first vendor we visited and were told that they did not carry it. No effort was made to recommend anything else and we left without making a purchase.As we walked through the market, I noticed th

    If You Decide To Not Work With An Agent, Are You Really Saving Money?
    We all like the idea of doing it on our own. We are accustomed to this because we seem to always think we can save money. But are we really? Let me show you how working with an agent in Canada will help save you money.1. The vendor has already signed an agreement with the broker for a predetermined fee. This fee is paid by the vendor not the buyer (you). 2. If you do not have an agent working with you, the list

    The die off happened in less than a million years (a very short time in geological terms) and the recovery took 5 million years to crank back up, and another million years after that to get rolling. While not deemed the smoking gun yet, this event coincides with the largest known volcanic eruption in history.

  • The Triassic-Jurassic Extinction occurred 200 million years ago.

    Was it caused by climate change, asteroids, or volcanoes? The verdict isn’t clear. What is clear is that 20% of marine life and many large amphibians were wiped out. At least half of all species on the planet bit the dust.

    This event occurred over less than a 10,000 year period, just before the supercontinent of Pangea began to break up.

  • The Cretaceous-Tertiary Extinction occurred about 65 million years ago.

    This event was probably caused, or at the least aggravated by, the impact of an asteroid around the size of Manhattan. About 16% of marine families and 18% of land vertebrate families ceased to exist. In North America, over 50% of plant species may have been wiped out.

    And of course…this is the event that doomed the dinosaurs.

  • The Holocene Extinction is occurring now.
