Binder, qui vitam gustat, nos hortatur ut videamus illum Archaeopteryx gregem. Malo dicere "Ecce grex Archaeopterygum!" (sive "Archaeopterygum lithographicarum"). My suggestion of "Archaeopteryges" was offered tongue-in-cheek; I have no problem with "Archaeopteryxes" or "Archaeopteryx" as plural forms. George Pesely peselyg@lynx.apsu.edu
