It's a garden-path sentence [1]. Garden-path sentences have ambiguous parses that typically require backtracking to correct earlier misinterpretations.
Well, the words "B.C." and "buried" are interpreted correctly in a grammatical sense either way. "Paris man with baguette" might be misleading if they're in Texas, but that's outside the scope of garden path sentences.
Only "Amazon packages" falls into the right realm. But is that enough to qualify as a garden path sentence? Personally, I wouldn't say so.
It definitely is. Because you think Amazon is a place, a noun, and thus you think "packages" is a verb - the woman is packaging something. Then you realize Amazon is a brand adjective. Definitely garden path.
I mean, not to be argumentative, but your personal opinion doesn't change the definition of the term. The first example on Wikipedia's article on it is "the old man the boat." Again, that's only one word, but it turns out there isn't a minimum word-backtracking-count to qualify.
In the particular case of headlines, where this arises more often thanks to their need for brevity at the cost of clarity, linguists sometimes call these "Crash blossoms" from the naming example "Violinist linked to JAL crash blossoms".

I think it's not a garden-path sentence because the sentence would be grammatically correct in the prehistoric/rainforest parse and even make some sort of sense.
Of course the meaning would be extremely weird - why would a prehistoric woman be buried with grave goods she refused and how would we even be able to know? - but I've honestly on par with the headlines and articles often posted here.
