What made the top quark significant was that it was the last quark necessary to complete the "Standard Model"(be72)

In the millions of Z's produced at CERN, Fermilab, and elsewhere, we have never seen this particular decay. This tells us something important about the top quark. It must be heavier than half of the Z mass. That's why the Z can't produce it(gp359)
The analysis gave a limit of 91 GeV for the mass, making the top at least eighteen times heavier than the bottom quark(gp362)
The standard model could accommodate a top quark as heavy 250 GeV, the theorists figured, but anything heavier would indicate a fundamental problem with the standard model. What is needed is at least five to fifty times the present number of collisions. This is the challenge for the 1990s(gp363)
Theorists argued that there 'ought' to be two more quarks to restore the symmetry. These were called top and bottom and evidence of bottom came through in 1977; the search for the top quark came to an end in 1994(sss142)
