Titanis
Titanis (meaning "Titan" for the Titans of Greek mythology) is a genus of phorusrhacid ("terror birds", a group originating in South America), an extinct family of large, predatory birds, in the order Cariamiformes that inhabited the United States from the early Pliocene to early Pleistocene. The first fossils were unearthed by amateur paleontologists/archaeologists Benjamin Waller and Robert Allen from the Santa Fe River in Florida and were named Titanis walleri by ornithologist Pierce Brodkorb in 1963, the species name honoring Waller.
