Primary description and phylogenetic analysis of a named phorusrhacid specimen, with sensory interpretations kept distinct from direct anatomy.
Phorusrhacidae is represented by the named Llallawavis specimen and its morphology-matrix placement within terror birds; sensory reconstructions and family relationships are study hypotheses, not a complete range or ancestor chain.
claim:taxon:phorusrhacidaePhorusrhacidae is displayed at 3.6–2.6 Ma only as the Pliocene Llallawavis specimen interval, not the family-wide FAD or LAD. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.
