I do, or that birds should be included in their group. It all depends how fine a point you want to make the classification

I made a poll about this. /wink.gif" style="vertical-align:middle" emoid=";)" border="0" alt="wink.gif" /> I think birds should be included in the dinosaur group, erase the group of birds and enter something else. Not dinosaurs since I believe that birds, sea reptiles, air reptiles are not dinosaurs but merely close relatives.

I agree there, I believe they are indeed close relatives of dinosaurs...
Also, birds "could" be classed off under dinosaurs too, but I'd still prefer it to be a close relative of dinosaurs instead..., I find birds more closely related to Raptors and Compys if you ask me...thats looking at body and bone structure AND the latest fossil findings from China (most of the rescent dino fossils from China have been found with feather-like membrane around them--similar to Archeopteryx).
Amphibians (to me) seem more closely related to the sea dwelling replitles... or maybe close to "primitive" reptiles that first walked on this land-- I wouldn't regard them as dinosaurs-- because Dinosaurs ONLY walked on the land (they didn't live in the water, or fly)...

if you look at the heart anatomy reptiles are 3 chambered and birds are 4 chambered.eventhough reptiles are 3 chambered are partially 4 chambered.i think dinosaurs would be 4 chambered

At least some dinos were 4 chambered remember Willow the dino with the fossilized heart?

Was that the brachisaurus one...?
Anyway, its sort of like a theory type of thing... because its been known for years now that organs decompose away...
But if the fossil was found preservered in limestone, then I guess the fossil would have been more "accurate" and more believeable because it would contain more detail...
Anyway, about Willow the dinosaur... does anyone have more inforamtion about this?

if they were 4 chambered i think they should be given a class of their own like birds and reptiles.
