Here is a slightly reformatted version of De Lacy's work. Counter arguments are in red, Epicurean arguments (mostly from Zeno of Sidon and Demetrius of Laconia) in black, with explanatory section titles. Not complete and still has some typos.

the person in Crete who was forty-eight cubits tall, according to those who examined the bones that were found

I wonder if they found dinosaur or ancient mammal bones. There was a Deinotherium (prehistoric elephant) fossil on the Greek island of Crete found in modern times.

Yes they were finding those elephant bones in antiquity as well. The large space in the center of an elephant's skull where the trunk attaches was figured to be the place for a single large eye of the cyclops.

I cannot find the evidence I thought I had for this statement! Perhaps it is a speculation.

Lo and behold, there's a book on this very topic:

Of course, elephant bones were present and recognized as such by those who were familiar with them.

I recently was thinking about "elephantos, India quorum milibus e multis vallo munitur eburno" "Elephants, many thousands of which fortify India with an ivory wall " (DRN 2.537), I always thought this "wall" was just poetic. I still do, but there is this:

Dio Chrysostrom (Discourse 79.4) “Again, if ivory is a marvelous possession and worth fighting for, the Indians are of all men most blest and pre-eminent by far, for in their land the bones of the elephants are tossed aside and no one troubles to go near them, just as in our land the bones of cattle and of asses are treated; they even say that in many places the skulls of the elephants, tusks and all, are built into their house walls”

Is that a metaphor for using elephant-mounted troops in warfare? Like Themistocles interpreting "wooden walls" as ships.

Yes I agree that war elephants are the main thing -- and probably the only thing -- that Lucretius is referring to. But the Dio Chrysostrom quote had me thinking for the first time perhaps there could be a bit more to it. We know that frozen Mammoth tusk huts are some of the oldest architecture discovered... Maybe there was a time in India when Elephants were as common as buffalo were in the Great Plains 150 years ago, and their bones were really so common that they became part of the architecture for some tribes for awhile.

This is all wild speculation. The climate in India would not preserve this, so the signs from which we can infer are few.
