Xeno Riddle

An anthropologist and a mathematician strolled through the forest.
Suddenly they came upon an extratresterial camp. The two
extratresterials, equally startled, dropped everything,
jumped into their nearby spacecraft, and disappeared amid a clap
of thunder.

The anthropologist rushed over to see what tools they had dropped.
He found two artifacts. One appeared to be merely a metal ball.

The other artifact appeared to be made of extremely durable
plastic. Otherwise it resembled an ordinary sheet of paper.
It had the following symbols embedded within it.

[.[].]
[.[]..[.[].].]
[.[.[].]..[.[].].]
[.[]..[.[].[.[].].].]
[.[.[].]..[.[]..[.[].].].]
[.[]..[]..[.[].].]
[.[.[].]..[]..[.[].].]
[.[.[]..[.[].].]..[.[].].]
[.[.[.[].]..[.[].].]..[.[].].]

The mathematician, studying the symbols,
exclaimed, "How could they have built such
an advanced technology using such clumsy arithmetical
notation?"

What do the symbols on the paper represent?

That mathematician is good. All I can see is that the pattern in the first is repeated somewhere in each of the succeeding eight patterns. And, the 1st, 3rd and 7th are symmetrical. And it's a good exercise in closing brackets. And they all start with [.[ and end with ].]

But wait! I sense it has something to do with primes....must be my human-alien hybrid brain starting to kick in...
