RE: Scientists conclude asteroid, not volcanoes, wiped out dinosaurs
Does that mean the post KT intertrappean beds are marine? Or terrestrial
with no fossils?

Yes; in at least one place, the boundary layer (complete with iridium
spike) lies within an intertrappean sediment bed, and sauropod eggshell
fragments reach all the way up to the boundary and then stop.
Unfortunately there don't seem to be any other Paleocene terrestrial
sediments in India, or at least I haven't heard of any. That's a great
pity, because there's currently no terrestrial fossil record in India
between the K-Pg boundary and the early Eocene when India had already
collided with Asia. The period of isolation isn't documented.
