That sounds like a good description of a giant lammergeier.
That was what originally brought the speculative cartoon to mind --
that, and the realization that there were many large bones in the
Mesozoic that could not be utilized by vertebrates as we know them today.
If what I read is true, an adult _Gyps barbatus_ can swallow and
(quickly!) digest bones that approach the maximum size that could
theoretically be surgically inserted into their bodies.
I would love to see anatomically knowledgeable speculation on the
maximum size femur a mega-biped like T. rex could _potentially_ swallow.
Or, as you say, a giant ptero...
I wonder whether some of the largest pterosaurs could have been lammergeier
I do not see that it could be ruled out. The resources were there, and
there are extant avians and crocs w/ "high-speed" bone-dissolving stomachs.
Heh. Perhaps someday someone will even notice dinosaur bones that have
fractures that could only have resulted from high-speed impact w/ rocks
when fresh. Seems possible, albeit unlikely...
have fit your above description well (if you removed the word 'terrestrial').
