[AndromedaChao2]

Have you noticed that Archaeopteryx has been moved to the reptilia clade? After all this time since its discovery 150 years ago they've classed it as a bird and now they class it as a theropod dinosaur due to some newly discovered creature being similar to it. I found that very disappointing

0:55 "im king of the world!!"

[darthrigel]

@NinoMaso OMG I am sorry I didn't see your comment I swear! I thought the same thing!! :-D

[NinoMaso]

@darthrigel that's ok my comment was 3 months ago

[AceofDlamonds]

lb for lb I favor mammals but in absolute terms, dinosaurs will always be my favorite animals of all time.

[efzt]

@AssofDlamonds Who cares? I like arachnids.

[AceofDlamonds]

@efzt

me two =)

[efzt]

@AceofDlamonds Quick response. Props.

[AceofDlamonds]

@efzt

lol. Just happened to stop by at the rite time.

btw, After dinosaurs (around age 8) my obsession was spiders. =)

[SlamTard]

we are never ever going to know what the dinosaurs really sounded like????

[TehHawtn3ss]

All my three year old daughter got from this was, "Dinosaurs open doors?" hahaha, awesome clip!

[RomanVlcek]

microraptor is in Prehistoric Park !!

[MrBrianbeyer]

I didn't even hear anything about the Archeoptryx. Most important evidence...

[fullmetalchymist]

I want a microraptor. Make it happen, biologists!

[Fieldzy14]

Mircro Raptors flying stance is wrong, Legs should be streched back.

[Dickified]

lol yeah that is so stupid of them

[drav1dan]

Microraptor had feathers on its feet too. It probably used these feathers like an airplane's rudder. For that to be effective, the legs would have to stick out into the airstream, just as shown in the clip.

[woldemort78]

this is cool but too short :(

[prehistoricsam]

interesting how this video shows a plausible theory of how Dinos became our modern day Birds.

[HyperChief117]

they didn't, the dinosaurs did NOT originate from birds. they originated from close spiecies of birds CLOSE! not the exact spiecies. try to get a little more of the slightest of details.

[armpitpuncher]

Actually, no. Birds evolved from therapods. Therefore birds ARE therapods. Therapods are dinosaurs. Therefore, birds evolved from, and still are classified as, dinosaurs.

[prjerry7]

@armpitpuncher Your forgetting when a species stops being its ancestor; Dinosaurs are one of the 3 superorders of the class reptilia [only 1 [the simplest] superorder of reptilia lives today], birds are in the class ave not reptilia. The simplest raptors were a transitional family from reptilia to ave just like the Sinapsids were a transitonal family from reptilia to mammalian. Your right about birds being theropods but they are NOT dinosaurs.

[Velox415]

@armpitpuncher But that's like saying mammals evolved from reptiles, therefore mammals ARE reptiles.

[armpitpuncher]

@Velox415 Reptile is refers to a polyphyletic group. That term is no longer used in taxonomy. Reptilia on the other hand, includes both anapsids and diapsids(including birds), but properly excludes mammals.

Even if there was a group called reptiles that mammals evolved from, what justification would you have for not calling mammals reptiles? When would that change occur? There would have to be some point where you would say, "these animals are reptiles, but their children are not".

[armpitpuncher]

@Velox415 Did we stop being mammals when we became primates? Did we stop being primates when we became apes? Did we stop being apes when we became human? (hint: No, No, and No)

[mystisme]

@armpitpuncher we were never apes but always and still are primates

[armpitpuncher]

@mystisme And how do you figure that? If chimpanzees, gorillas and orangutans are apes, and chimpanzees are more closely related to us than they are to gorillas, and gorillas are more closely related to us than they are to orangutans, how can we not be considered apes? That would make "ape" a polyphyletic group, and polyphyletic groups are not recognized in taxonomy. Therefore, if "ape" is a taxonomic group, (it is the common name for "Hominoidea") then it must include us.

[Voyksed]

@armpitpuncher yep. and we're monkeys too, since apes are a group within monkeys, and more related to old world monkeys than to new world monkeys.

I love cladistics.

[Avatar23561]

@HyperChief117 That's true, it is suggested birds originate from dinosaurs.

[000mgarcia1]

@HyperChief117 You are absolutely correct! Dinosaurs could not have evolved from birds, but birds did evolve from dinosaurs.

[GoofyGeeks]

i love microraptor!

:O birdies
