<p>[QUOTE=&quot;superc, post: 1743816, member: 44079&quot;]He had me right up to chapter 4.&nbsp; LOL</p><p>&quot;then in the future people discovered how tasty the dinosaur meat was. And so humans hunted dinosaurs for food.&quot;</p><p>No way dude.&nbsp; The humans and the dinosaurs were millions of years apart.&nbsp; </p><p>Also&nbsp; you are mixing extinction events.&nbsp; There was one extinction that was&nbsp; fast.&nbsp; That was the first one.&nbsp; Old Mr. T. Rex wasn&#039;t around yet.&nbsp; In&nbsp; that one basically anything larger than an amoeba living in the bottom&nbsp; of a deep ocean trench died.&nbsp;&nbsp; The cause is believed to have been a&nbsp; stellar event.&nbsp; Which star no one knows.&nbsp; Could have even been our own.&nbsp;&nbsp; Other extinction level events were much less quick.&nbsp; Some took&nbsp; thousands of years.&nbsp; The phrase nuclear winter comes to mind.&nbsp; It may&nbsp; have been like that.&nbsp; Years of winter.&nbsp; Or like Venus, years of burning&nbsp; hot.&nbsp; Dunno.&nbsp; No one was there.&nbsp; What we do know is T Rex wasn&#039;t alive&nbsp; on Tuesday but extinct on Friday.&nbsp; He died hard, he died slow.&nbsp; Like a&nbsp; thousand years before he and his ilk were all gone.&nbsp; Something&nbsp; progressive.&nbsp; Of course our atmosphere also changed, so did our gravity&nbsp; (the earth increases in size 1/4 inch every year due to a constant fall&nbsp; of space dust.&nbsp; Their is a biological rule called the cube roots law.&nbsp;&nbsp; Double an animals size, he is now 4 times as strong, but he is now 8&nbsp; times as heavy.&nbsp; Under the cube root law with today&#039;s metabolisms, Mr. T&nbsp; Rex and Mr. Stegosaur can barely move, much less run.&nbsp; Yet they did.&nbsp;&nbsp; How.&nbsp; Muscle strength comes from metabolism.&nbsp; Metabolism comes from&nbsp; Oxygen reactions.&nbsp; Back in their day the air of the earth had almost 3&nbsp; times as much Oxygen.&nbsp; There were some serious fires from those asteroid&nbsp; strikes.&nbsp; Much of the Oxygen became CO2.&nbsp; So your dinosaur&#039;s&nbsp; metabolisms became more and more inefficient.&nbsp; Hard to move.&nbsp; Difficult&nbsp; to generate body heat.&nbsp; As the fires burned each successive generation&nbsp; had a harder and harder time.&nbsp; Essentially the big guys smothered.&nbsp; One&nbsp; thing we have learned.&nbsp; Mammals are really old.&nbsp; Many mice-like things&nbsp; lived in and through the dinosaur era.&nbsp; Timid burrowing critters.&nbsp; As&nbsp; the big guys began to die off, the mice like critters came forth.&nbsp; Being&nbsp; mammals the temperatures didn&#039;t effect them as much.&nbsp; Being smaller,&nbsp; and with a more efficient metabolism they needed less Oxygen.&nbsp; Tens of&nbsp; millions of years later, here we are, wondering if we should care about&nbsp; fossil fuels and global warming.&nbsp; The cycle begins anew.&nbsp; At least the dinosaurs didn&#039;t do it themselves.[/QUOTE]</p><p><br /></p>
