p>trilobite-extinction (1)A microbial feeding frenzy may have fueled the biggest mass extinction in Earth’s history, new research suggests.

The findings suggest that bacteria, with a little help from massive volcanism, produced large quantities of methane, thereby killing 90 percent of life on the planet.

Mass extinction

About 252 million years ago, more than 96 percent of ocean life and 70 percent of land-based life forms died in an event known as the end-Permian extinction. The mass die-off happened in a geologic flash of just 60,000 years. Scientists have proposed everything from massive meteor impacts to coal explosions to rifting super-continents to explain this cataclysmic extinction. 

Rocks from that time period in locations such as Meishan, China, show that atmospheric carbon-dioxide levels skyrocketed right around the time of the extinction. Sediments also show that during this time, the largest set of volcanic eruptions in recorded geologic history called the Siberian Traps spewed enough lava to cover the entire landmass of the United States, said study co-author Gregory Fournier, a biologist at the Massachusetts Institute of Technology. Therefore, many researchers have theorized that the Siberian Traps could have belched out the extra carbon dioxide, choking life on the planet.

Deadly microbes?

But if volcanic eruptions caused the great dying, shifts in carbon should occur as big bursts followed by gradual decays. Instead, the carbon-dioxide (CO2) levels rose at faster-than-exponential rates, which points to a biological cause of the shift, the researchers said.

Always ready to help others, he shares what he learns on multiple blogs, social sites, and more. With a background in preparedness and survival skills, training with county, state, and national organizations, and skills in all areas of media and on air experience in live radio and television, Rich is always thinking about the "big picture", when it comes to helping individuals and families prepare for life's little surprises. Since 1997, he has provided guidance, authentic government survival history, and commentary on why we all need to get ready for that fateful day in the future, when we have to get our hands dirty and step in to save the day. He is an award winning videographer (2005 Telly Award), has received state and national scholarly recognition (2006 New Century Scholar and All USA Academic Team), and is a natural with computers, technology, gadgets, small furry mammals, and anything on wheels. Rich likes making friends, solving problems, and creating solutions to everyday issues. He doesn't mind mixing things up, when there is a teaching moment ready to happen. As a constitutional conservative, he's staying quite busy these days. The SurvivalRing Radio Show at www.survivalringradio.com will be coming back SOON!
