Re: T.rex Animation
In the case of the purported Hell Creek Cannabaceae, I don't know what
characters were used in the assignment.
But in the case of _Palaeoaster inquirenda_, its inclusion in the poppy
family was done using a suite of fruit characters, which pretty much
nails down the assignment, IMHO. Classification of living angiosperms
also uses characters of the fruit.
But I agree that a lot of convergence probably occurs in leaf
