Dinosaurs did not become extinct they evolved?

[cj wisty]

this theory of yours has been rejected after decades of study on pterosaurs

[Ol' Dirty Trixˣ]

that thumb is enormous. its as long as the pterosaurs limb.

also ur missing the fact that one is quadrapedal and the other is bipedal.

and the way they stood is very different. the way they flew is also very different. a T-Rexs skeleton is structured more like a birds

that 'thumb' might look quite big compared to the feet, but it is tiny in comparison to its wings, it's more likely to damage that little 'thumb' having to carry big heavy wings like that around. you don't know that it was quadrapedal, that pic you showed could have been the foot and wing prints of an injured pterosaur that had to walk in that position, have you considered that?

trix u need to look more into the differences of homology and convergence

this diagram actually says its a finger not a thumb lol. but either way that finger is obviously huge

[Ol' Dirty Trixˣ]

it is not huge when you consider the other bones on that wing.

[cj wisty]

it is not huge when you consider the other bones on that wing.

its over 3 times longer than every other bone

[Ol' Dirty Trixˣ]

the bones shown in blue and the bones shown in green is showing that they are bigger than the bones in pink.

[cj wisty]

look at the key. it shows that the green bones are the fingers. and that finger is indeed massive

[Ol' Dirty Trixˣ]

it's more related to bats because of that little bone? not the absence of a beak or a long neck (many, many bones) but because of that one little bone? birds normally have three but that has four and it would make that much difference?

[Ol' Dirty Trixˣ]

bats spend most of their time hanging upside down or flying around and only walk when they need to.

[Ol' Dirty Trixˣ]

the bat appears to be walking on its thumb.






the 'arms' on this appears to have been walking on three digits.

how do kangaroos factor in?

[Ol' Dirty Trixˣ]

are they coin purses or key rings? ewwwwww.

how do kangaroos factor in?

yeah, it could have been more related to kangaroos. difference is the placement of the rib cage and the feet on the kangaroos are bigger. i reckon it was furry.
