Some dinosaurs may have survived the extinction!

I found this quite interesting. They may not be around today walking among us but their descendants most likely evolved into flightless birds![youtube]http://www.youtube.com/watch?v=0dLgakPQCkg[/youtube]

Crocodiles and alligators are examples of surviving 'dinosaurs'.

Yes. The Dinosaurs did survive. We call them birds.

I cant see the video you posted on this computer.

There were man sized flightless dinosaurs cloaked in feathers that were cousins of early birds in the mesozoic. But they did not survive.

Modern flightless birds are all descended from birds that could fly. Ostriches and Moas did not evolve directly from dinosaurs-but from small modern looking flying birds that got big and secondarily lost flight ( they retain many physical adaptations to flight that they no longer need).

But all birds today, flying and nonflying, seemed to have evolved from small minaturized versions of the hunting dinosaurs like raptors and T-Rex. Some say that they not only evolved from dinosaurs-that modern birds all ARE dinosaurs.

Since bird species outnumber mammal species that would mean we are still living in "the age of dinosaurs".

But there is atleast one bird scientists (the dissenting voice on pbs shows) who still resists this new fangled notion "pushed by dinosaur scientists and latched onto by the public" that "birds are descended from dinosaurs- or even ARE dinosaurs". He still pushes a non dinosaur model for bird origins.

But even he classes birds with the thecodonts- the group of reptiles that includes crocodiles and alligators that also gave rise to the dinosaurs. So even if birds are not themselves dinosaurs, they are atleast cousins.

Some dinosaurs did. They're called reptiles and birds.

It's called evolution.

Birds have survived, though I wouldn't call them dinosaurs. I associate the word "dinosaur" with the extinct animals.

A very cool concept, yes. (I wonder what about their design allowed them to survive the mast extinction. Only size?)

I've heard/read of sharks being non-literally described as 'dinosaurs' because they have not changed much over 420 million years!

The first time I heard this, I found it pretty hard to believe. But then one day I was eating lunch and watching a seagull. I looked at the seagull's legs and feet and suddenly felt stupid for not making the connection before.

I fixated on dinosaurs when I was quite young. Sometimes I relapse, so research them intensely. This theory has bored me for a while - I much prefer the ancient creatures of old to birds, though I love birds of prey.
