"The Paleozoic period, about 300 million years ago, was a time of huge
and abundant plant life and rather large insects -- dragonflies had
two-and-a-half-foot wing spans, for example. The air's oxygen content
was 35% during this period, compared to the 21% we breathe now, Kaiser
said. Researchers have speculated that the higher oxygen concentration
allowed insects to grow much bigger."

If this was the case then why don't you show us, by raising some in a
large oxygen rich terrarium?
I'll tell you why, because your theory doesn't hold water.

350 million years ago, the claim has been made that dragonflies had a
wingspan of 2 and 1/2 feet. Can you demonstrate that the engineering
of the body structure would allow it to fly at that size?

Here is a giant cockroach from 300 million years ago.http://news.nationalgeographic.com/news/2001/05/images/1112_cockroach...

Does it not seem more probable, that since the earth is expanding,
that fossils have expanded as well?

It may not be completely linear, but as rock is compressed by some
forces of nature and expanded by the earth's expansion as seen in the
ocean rock age data, then this could account for the dinosaur bones
found of immense proportions as well.
Those that have been found, that are too large to have lived on earth,
should be suspected of having expanded.

The earth may still have gained mass from dust and ice captured from
space, but perhaps some fossils have double in size from their
original.

No. I give up. I can't work out if the poster is serious or not.

It is, though, a seriously weird post.

I get the impression it's another szchizoid.
