So what might have caused this great dying? This greatest of mass
extinction events?
Some evidence of rock shock, which might suggest asteroid impact, but
no impact site.
Possible birth of giant volcanoes at the end of this period.

This happened 251.4 million years ago. With 96 percent of all marine
species and 70 percent of terrestrial vertebrate species becoming
extinct.

The oceans hadn't formed yet, there were just shallow seas. The oceans
began forming approx 180 million years ago. But fungus flourished. And
well once things die within a year or two the fungus flourishes and
then the matter is consumed. Maybe a hundred years for a cedar tree at
most, so if the age of fungus was a few million years, then the
climate must have been a major factor in order to stretch out the
great dying.
A single event like the impact of an asteroid might kill everything
off but that would be a short quick end to it.

Um, pray, what would replace the fungi? If most land plants and critters had
gone belly up, what would keep teh fungi from being dominant for a
considerable time? I think you are not realizing the scope of the
catastrophe, but letting your vision be controlled by modern 'disasters' like
local fires, floods, or volcanoes, which all have thriving ecosystems at the
margins all ready to repopulate the devastated area. If you are talking about
devastation on a global scale, I think you need to recalibrate what seems
reasonable.

Well what would they feed on, after the food was gone? If there was a
great die off, if it was sudden, like an impact, would kill things off
relatively quickly, they would eat that debris, then what would keep
them at that elevated level?
The fungi would then die off.

Unless, the vegetation continued to grow, and the climate was wetter,
and it eventually killed the vegetation off.



Ambient pressure of space?? What the Sam Hill are you talking about???

The expansion of the universe. It is accelerating.
The Cosmological constant portion of GR that balancing force against
gravity, which keeps the universe from collapsing on itself, that is
akin to ambient pressure. It is referred to as the pressure of the
universe. Like the permitivity and permeability of free space.

"A positive vacuum energy density resulting from a cosmological
constant implies a negative pressure, and vice versa. If the energy
density is positive, the associated negative pressure will drive an
accelerated expansion of empty space; see dark energy and cosmic
inflation for details."http://en.wikipedia.org/wiki/Cosmological_constant



And was that when the maria began forming on the moon as well?
The age of the maria has been estimated at, you guessed it, 200
million years.

By whom??? As far as I know the published dates for lunar mare basalts
cluster around 3,900 million years.

Rick, I earnestly suggest that you do just a little research before you post
stuff like this.

It quite easy to see what is happening on a very large scale.
1) The expansion of the universe is accelerating.

The Accelerating Expansion of the Universe
http://www.physicstoday.org/vol-58/iss-4/p39.html

Gravity is equivalent to accelerated mass. (see Einstein's elevator
experiment which led to GR)

Gravity is caused, by the expansion of the universe. Space-time is
curved.

So if the universe is expanding faster, then gravity is increasing and
planets are expanding faster.

But if you examine the moon, the maria show a growth spurt.

Just like the oceans on earth, show a growth spurt, all around 200 to
250 mya.

So my question is, what happened, to cause the loss of pressure, which
led to that growth spurt?
