Dinosaurs did not become extinct they evolved?

i think the head is on the wrong way round.

i think i love trix. she's not afraid to think outside the box. conversely, im trying to think of ways to get inside her box.

that's sweet. i don't know if i would consider it as thinking out of the box, cos i have followed the rules.

perhaps it was those palaeontologists that thought outside the box?

lol wheres our resident dinosaur enthusiast aka tetris at?

as far as i know reptiles don't fare well in cold climates, they're more likely to be found in warmer climates.

The same can be said for females.

All dinosaurs evolved into riff raff

i still don't think that 'bird' was a bird. there are other skeletons that are more bird like.

i reckon this ^ one had feathers. flamingo/heron looking. i can see it with feathers and not scaly like in the artists version of what it looks like in google images. large wingspan and beak and short tail. if you took the head off of that and turned it around then put it back on again, the beak would look more in line with those birds i mentioned.

its a common misconception to think that birds came from pterosaurs. from study of the skeleton system pterosaurs walked on four legs and had four limbs whereas birds walk on two legs and have only two limbs.

large wingspan and beak and short tail arent really good evidence that birds and pterosaurs are related.

similiar wingspan is probably a result of convergent evolution and not because pterosaurs are ancestors of birds.

im also pretty sure pterosaurs were extinct a long time before the first birds.

tbh i think most of the connections youre making are just features of convergent evolution and not because the animals are closely related.

its like trying to say salmon and dolphins are closely related because they both have similiar shaped bodies fins etc when in fact dolphins and fish belong to totally different class.

i didn't say they were closely related, the thread title says they've evolved.

a dolphin might be different to a salmon, i'm not trying to argue that. but they both swim in water in a similar fashion, the way a dolphin or salmon swims in the sea would be different to how a dog would swim in the sea.

having a beak would suggest that it's a bird. how many other types of animal are there that have beaks? if having large wingspans and a beak doesn't suggest it is bird like then what does it suggest to you?

how many reptiles have beaks and wings?

stork

octopuses and squids also have beaks. trurtles also have beaks. as for wingspan. all vertebrates with wings have similiar wings. its because of convergent evolution. and birds usually have smaller wings than pterosaurs. so that point doesnt stand up well at all.

large wing span and beak doesnt suggest bird because ptreosaurs were extinct a long time before birds and theres no animals found that look part pterosaur part bird. theres barely any evidence to suggest that birds and pterosaurs are related.

no reptiles have both beaks and wings.

the problem youre having is that you dont understand most of these connections are because of convergent evolution.

its why bats and birds have a similiar wing structre but arent closely related.
