Dinosaurs and other prehistoric creatures

[DoomRulz]

That wouldn't make sense, because not all dinosaurs evolved into birds. Only the theropods did. What happens to the herbivores?

[Puks]

I'm confused myself..

Systematically speaking, you and me are still part of clade Sarcopterygia, lobe-finned fish, even if we evolved much further and don't resemble fish now at all.

The same applies to birds, even if they are miles away from "classic" reptiles, the clade Aves is part of Reptilia/Sauropsida, and further part of  Amniota, Tetrapoda, Sarcopterygia, Vertebrata, etc.

All sauropsids and their descendants are reptiles and some reptiles are birds.

This is what happens when you let bureaucracy get in the way of common sense .  There are many who don't agree with the reclassification of aves and would rather restructure the entire dinosaur superorder.

It is common sense, I'm just confused about Zilla's confusion.

I can believe it Puks. Our oldest ancestor was a fish.

[Noir-Gojira]

Except that we are no longer classified as fish.  Or reptiles, from which we also evolved.  Unlike aves, mammals retain their own class for little better reason than because our girls have boobs :P

Exactly.  The term 'dinosaur' may no longer even apply to all of them.  Like I said, science can take categorizing too far.

We're not part of "fish" sensu lato, but Sarcopterygia, yes.

We haven't evolved from reptiles. Mammals and their ancestors - Synapsida and true reptlies - Sauropsida are sister clades in the higher clade Amniota. Aves are rightfully considered reptlies because they're sauropsids. Big difference.

Exactly.  The term 'dinosaur' may no longer even apply to all of them.  Like I said, science can take categorizing too far.

Dunno about you guys, but when I think of the term "dinosaur", both Ornithischia and Saurischia including birds come to my mind.

When I think dinosaurs I think Jurassic Park.

I'm just confused about Zilla's confusion.

I'm confused about your confusion about my confusion now.

When I think dinosaurs I think Jurassic Park.

Those are Monster-a-saurs with Frog DNA.

When I think of Dinosaurs I pretty much think of the "Walking with dinosaurs" series. The CGI was not so good but for a documentary they did a decent and realistic job.

As do I, but you're not going to hear someone like Bakker or Currie argue that birds evolved from Triceratops or Sauroposeidon

[Puks]

Perhaps I missed the point? 

[DoomRulz]

I just mean that, when discussing the evolution of birds, we only talk about the theropod dinosaurs so re-classifying the entire species would be pointless. Ironic though, when you consider that Ornithiscia means "bird-hipped" yet only the herbivores are classified as such.

Dinosaurs are cool...

[Necrokult]

Whats is your favorite pre-historic dinosaur and why? give a comment

For me the Velociraptor cause they were fast, deadly and more smarter than primates, they worked together and hunt together. they are awesome.

[Meathead320]

That would be GODZILLA.



He is 500ft tall, and cleanly beat the raptor at Badassery.

[Necrokult]

dont forget Godzilla is a myth and look at that godzilla ahahhahaha
