“…Our comprehensive phylogenetic analysis places Llallawavis as a derived member of Mesembriornithinae (Fig. 10) and sister taxa of Procariama, a genus previously considered part of Psilop-765 terinae (Alvarenga and H€ ofling, 2003;Agnol ın, 2009Agnol ın, , 2013Alvarenga et al, 2011;Vezzosi, 2012a). Characters supporting the inclusion of Llallawavis within Mesembriornithinae include the presence of a triangular asymmetric hypotarsus and a third metatarsal trochlea that is widened distally.…”

“…We developed a character matrix by independently evaluating the character matrices reported by previous authors [10,23,25,26]. We added Falco peregrinus, Llallawavis scagliai and Titanis walleri to the character matrix using our observations and previous descriptions of the fossil material [1,10,24,29,32,33].…”

“…Previous analyses regarding the interrelationships of phorusrhacids have been inconclusive because of their sparse fossil record. Most species lack significant amounts of skeletal material and therefore lack diagnostic osteological traits [10,[23][24][25]. Alvarenga & Höfling [1] attempted to clarify their systematics, but they did not place individual species within a phylogenetic context.…”

Terror birds (Aves, Phorusrhacidae) were large flightless apex predators in South America during the Cenozoic. Here, we estimate a new phylogeny for phorusrhacids using Bayesian inference. We demonstrate phylogenetic evidence for a monophyletic Patagornithinae and find significant support for a distinct crown group associated with the quintessential ‘terror bird’ characteristics. We use this phylogeny to analyse the evolution of body size and cursoriality. Our results reveal that size overlap was rare between co-occurring subfamilies, supporting the hypothesis that these traits were important for niche partitioning. We observe that gigantism evolved in a single clade, containing Phorusrhacinae and Physornithinae. The members of this lineage were consistently larger than all other phorusrhacids. Phorusrhacinae emerged following the extinction of Physornithinae, suggesting the ecological succession of the apex predator niche. The first known phorusrhacine, Phorusrhacos longissimus , was gigantic but significantly smaller and more cursorial than any physornithine. These traits likely evolved in response to the expansion of open environments. Following the Santacrucian SALMA, phorusrhacines increased in size, further converging on the morphology of Physornithinae. These findings suggest that the evolution and displacement of body size drove terror bird niche partitioning and competitive exclusion controlled phorusrhacid diversity.
