Evolution. Repost, but it's hilarious.. the size diference is because the oxygen content of the atmosphere being much lower today. Its biologically impossible for reptiles to grow so large now

evolution supposedly makes things bigger, faster, smarter yet it turned dinosaurs into birds....the whole theory sounds like a desperate attempt to explain reality without God.

not necessarily bigger, but more efficient

Wouldn't larger reptilian creatures have died out, leaving smaller creatures to evolve into chickens?

Actually birds evolved before the dinosaurs went extinct however they are also an extant group of reptiles basically meaning birds while they are basically advanced dinosaurs have changed so much they gained a new classification. As for the Tyrannosaurus family only the T. Rex was actually large most species of that family were around raptor height so the connection to smaller form is not unusual. In fact Great Whites are the only living descendants of Megladons yet they themselves due to decreasing oxygen levels in the water resulted in a smaller body size over time.

They say the T-Rex might possibly had feathers.

Im okay with it, if it looked anything like this. Though we might never know...

No idea about the T-rex, but I do know archaeologists have stated that velociraptors did have feathers.

What a ******* tease!
You have no arms, so evolution gives you some arms and takes all your badassery away and makes you into some slenderman retard parrot. Then it takes away your arms again, making you eve more useless. Then it's like, "hey, sorry about all that, so we're going to give you some wings," but guess ******* what, you can't ******* fly!

The theory is that there was a lot more oxygen in the atmosphere back during the age of the dinosaurs, which allowed mammals, reptiles, and other species to grow much larger. They are not able to grow to such sizes today with the lesser amount of oxygen in the atmosphere.

Actually oxygen was only about 50% higher back then, at it's highest, and lower than today at it's lowest (as a side note, CO2 was about 600% higher), it may have contributed to their massive size, but it wasn't the main reason. Dinosaurs had bird lungs (or more properly, birds have dinosaur lungs), so they were extremely efficient at getting oxygen out of the air. The Mesozoic was also a warm period, which helps increase animal diversity. Size is a good strategy, if you're too big to eat, you won't get eaten, and if you don't get eaten, you make more babies. It works the same way with carnivores, the bigger your food is, the bigger you have to be to take it down, unless you change strategies and try pack hunting (or eating plants, therizinosaurus I'm looking at you). Mammals have gotten huge before too, and that happened without significant boosts in oxygen.

Also, in reference to your comment below, the giant dragonflies are from the Carboniferous period, which is long before the dinosaurs first appeared.

I'm studying to be a paleontologist, if you guys have any further questions!

I was just thinking...over the course of thousands of years we could take a population of rats and make the undergo natural selection by killing one off with undesirable traits. Technically speaking we could make these rats evolve into pikachu!

T-Rex turned into a chicken, brilliant. Even though people were fighting them in medieval times (dragons).
