The catapults at the site were engraved with a pitchfork, the emblem of King Antiochus IV.

They mean the catapult bolt-heads, as illustrated, assuming they aren't just big arrowheads.

How do they compare to arrow heads used by Cretans? (or Similar)

http://www.archaeology.wiki/blog/2013/11/04/antikythera-history-and-antiquities/  has some arrow heads but no scale

They look very similar, that's exactly the type of arrowhead I was thinking of. I had thought of catapult-bolts, by contrast, as being socketed, but that is purely from memory and I haven't had time to check any references.

For anyone who became discouraged flipping through the selection of photos on the archaeology wiki site, here is a direct link to the Cretan arrowheads Jim mentions.
