What does trilobite do?

An untitled poem, from Clark Coolidge's Space (1969):

ounce code orange
a
                the
                              ohm
trilobite trilobites

Of which Kasey writes:

Even in the absence of a clear grammatical structure, it is still difficult not to read even abstract linguistic assemblages of this sort on the model of normative syntactical connections between words. One might read the first line as three listed nouns in a series, or alternately one might treat ounce as subject, code as verb, and orange as object...

For whatever it's worth, I find it easier to make a "clear grammatical structure" out of the last line. While it initially seems a repetition of a noun, first in the singular and again in the plural, I read it as consisting of a singular noun and an intransitive verb.
