Pyrrhus' peltasts, slingers, and archers began to shoot and his sarissa-wielding phalanxes began to attack. Foot soldiers were organized into heavy infantry phalanxes called "phalangites". He had 39,000 infantry, half of which were phalanxes (heavy infantry). The Greeks and early Romans used rigid, heavily armed phalanxes. The Ptolemaic and Seleucid phalanxes engaged in a stiff and chaotic fight. The Ptolemaic and Seleucid phalanxes then engaged. The phalanxes engaged and a stiff fight endued. The Macedonian phalanxes were made up almost entirely of pezhetairoi. The phalanxes made seven attacks, but failed to pierce the legion. Seeing the spartiates fleeing in disarray, the perioeci phalanxes also broke ranks and retreated. Phylogenetic analyses have determined that many of these subgenera, phalanxes, and sections are not monophyletic. The opposing phalanxes meet each other almost simultaneously along their front. "Breaking phalanxes" illustrates more of the Roman army's flexibility. Nine distal phalanxes (claws) from an adult "Panthera spelaea" were discovered in the Lower Gallery. Fourier's prescription was the establishment of communities called Phalanxes or Associations in the countryside.
