Yeah, ONLY. Could you tell me how long ago the insects were so big. More than 300 million years ago, there was 31 to 35 percent oxygen in the air,” Dr. Kaiser said. “That means that the respiratory systems of the insects could be smaller and still deliver enough oxygen to meet their demands, allowing the creatures to grow much larger. http://www.sciencedaily.com/releases/2007/08/070806112323.htm

I'll have to find what I was watching if you guys want verification. But it seems the abundance of c02 caused plants to grow much quicker and more thickly dispersed than today. Downside was the nutritional content was less than half current average for same plant. Here's where theory steps in... Because of this a chain reaction started... Dinosaurs needed to eat more to get nutrition, and the size of the stomach needed for processing all this plant material it seems kicked off the growth. Next the other organs had to get larger and larger and finally they became massive. Now this only concerns... [More]

Do they really survive for long 50 million years ?

Things were much larger in the past because there was more oxygen. There was more oxygen because there were more trees. We cut down too many trees wich is why we're tiny.

I'm sorry,but I thought that insects from that long ago were supposed to be really big? Well, you had giant dragonflies which had wingspans of more than 75 cm... but that was like 300 mya

I bet we became tiny coz we multiply very fast that we c0nsume m0re oxygen everyday...and then we cut trees.. But who cares im n0t 4ever only th0se of nxt genrti0n will suffer... By the way only bcoz we are n0t present n dinosaur era thats why they gr0w very huge..if we were there i bet they will bec0me ham,hotdog, steak, etc.

yeah less oxygen and cooler climate. Things were much larger in the past because there was more oxygen and the climate was warmer
