Well fossils that is.
xP

The remains of a huge beaked dinosaur with the looks of an ostrich but the weight of a rhino have been discovered in China's Gobi desert, fossil hunters have announced. [X]

This dinosaur is called the Gigantoraptor erlianensis and lived about 70 million years ago. According to this article it is the largest toothless dinosaur known, and possibly the biggest feathered animal to ever have lived.

Most theories suggest two-legged dinosaurs known as theropods gave rise to birds after certain groups became progressively smaller, but Gigantoraptor appears to contradict this evolutionary trend, the paleontologists report. [X]

"We thought previously that we had a relatively simple pattern—as dinosaurs became smaller in size they became more birdlike," Xu said. "Now, after the discovery of Gigantoraptor, things get more complicated.
The fossil also resembled the body structure of a bird more than any ever found.

There has been doubt over the theory that dinosaurs had feathes and gave rise to birds.

In a related article [X] experts concluded that distinctive patterns found on the skin of a Sinosauropteryx fossil ( a turkey-size dinosaur)
were evidence of protofeathers, but a new team studies resulted in the Sinosauropteryx actually being bald.
Lingham-Soliar and colleagues' results support there's no evidence of dinosaurs ever having feathers.
According to the article, weather or not these dinosaurs had protofeathers was the only critical evidence they had to support that these reptiles gave rise to birds.

Here is another article about bird genes found in dinosaurs.
Turns out T-Rex was king of the dinosaurs with a gene package the size of a hummingbirds. xP

[X] And here is another that shoot's down the theory that birds evolved from dinosaurs.

The distinctive patterns that some scientist say are deffinate proof of protofeathers others say they are fibres which show a striking similarity to the structure and levels of organisation of dermal collagen, the kind of tough elastic strands found on the skin of sharks and reptiles today.


arrow With that in mind, what are your ideas about the theory of birds evolving from dinosaurs?
What about the newest dinosaur found, which is very bird like but also gigantic - which contradicts the birds evolving from dinosaurs theory?

whee

I just saw it on the news, when I got on line today.
I thought it was rather interesting.

I can agree with the theory of birds decending from Dinosaurs...
I have no hard facts, other than I think they look like giant featherless birds.

This is very interesting, the people told me that the birds descended of the dinosaurs, but I’m not yet very convinced, I need more information idea .

hmmm...well here's my take on it, we all know that the reason a species evolves is because of it's environment no? natural selection picks out the needed traits to prove that an animal or organism can survive better with that particular trait. What if the traits to help an organism in that time period where merely the same as current birds today, mind you Natural selection doesn't know that certain traits will make(in this case) something fly of course, if the traits work then the organism survives right? Well, perhaps at this time period, size was not an issue on survivability, so it wouldn't have mattered and the Gigantoraptor(name kinda makes me laugh) was able to survive because of say it's beak or wing like structure and the speed that it gains while running with hollow bones. This was the trend for alot of "Dino-birds" then right? maybe in the end of the time period that it existed size did become an issue, so it became extinct/evolved to become smaller and the other smaller "Dino-birds" were able to survive due to size, and went on to develop the other bird traits for whatever reason the environment chose for survival. I mean if size didn't become an issue, maybe we would have 30 foot tall birds flying around. That would actually kind of scare me, they could totally just fly off with us when we are walking to work or something. eek

other note on T-rex. For those who don't yet now, The T-rex was probably actually just a scavanger using it's size to scare off other scavagers. T-rex is no longer "King o' the Dono's" eh? That's ok The Raptor genus is much cooler anyways I think. mrgreen

And a quick Question, if you guys are in the united states does your state have a state Dinosaur? Colorado's is the Stegosaurus.

coolies, I'll have to read it before I go to work tomarrow. Yeah, 1800's wouldn't surprise me. Hmmm, I'm gonna have to make a newthread tomarrow about Evolution and of course religion. Mybe Some one will share my similiar opinion. But I shall save for said thread.

Yeah the only reason I know my state Dino is becasue I had always wanted to become a paleotologist when I was a little kid in elementary school.

Heck...I might start a thread about Geology tomarrow too. mrgreen

When was this discovery? I thought I heard about it a few years ago...
It is possible for birds to have evolved from dinosaurs though...

As a preliminary opinion, as I have not so much time to read the articles as of now...

Birds evolved from a subspecies mutation in a dinosaur gene, thereby having similarities to dinosaurs as we see in photos and evidence.

Note that this is a preliminary opinion, very likely to change as I read on...

I'm not too familiar...
what is it?
