If we accept the theories that posit drift from Pangaea through the
Laurasia/Gondwanaland phase to the present, we find that the area
that's now Yucatan is much closer to the Deccan plateau. Global maps
I've seen that represent the Cretaceous show a smaller Atlantic and a
larger Pacific than we now have; the implication from this is that the
modern position of what was then the andipodal piece of crust is
probably in eastern Australia, now even farther from the plateau than
the present antipodes point.
Again, I'm not a geologist, or even a physicist; but I get an idea once
in a while, and when I do, look out! :-)
