Back then the solar system was probably more dusty than it is today. Maybe the earth rotational speed was faster than today but whatever that was one heavy bug and I doubt it could be frisky (regardless of atmosphere) in today's world due to gravity alone..
I figured it out given the average rate of yearly rotational decline of the Earth, and days back then averaged 18 hours, 21 minutes long.
The moon was also closer, and looked a little bigger. It moves away from the Earth at about an inch a year, so it was, at the time, about 326 million inches closer, 27 million feet, 5145 miles).
When the oxygen peaked at 32%, forest fires were all over the place (sparked by lightning and such) because of the increased oxygen to fuel ratio. They still find ash layers from it in coal mines.
The article estimate that Arthopleura weighed 50 kg/ 110 lbs. Now that's a big damned bug! The last centipede I caught fit into a wine bottle. No such luck with that bugger!

Good figuring IMO !
