"Abortive"? How do you know this? Or did you mean
"they went extinct"? If you meant the latter, then I
could agree in principal with you.
"Abortive" implies the perjurative that the body plan was
not desirable for the environment in which it exists.
Certainly, you are not claiming that bipedalism is
a non-desirable character trait?....or are you?

A delicate vertebrate fossil buried in soft sediment is a lot
different in terms of survivability than is a 1,000,000
metric-ton pyramid composed of two-ton blocks 2-3 meters on a side.
You make the most unusual analogies, sometimes! :-)
