Masillaraptor Parvunguis
''Masillaraptor'' is an extinct genus of masillaraptorid, a groups basal falconiforms, from the Middle Eocene Messel Pit, Germany. It is a long-legged relative of the living falcons. Known species Only one species of ''Masillaraptor'' is known: ''M. parvunguis'' Etymology ''Masillaraptor'' comes from the Latin word ''Masilla'', which is the old name for the town of Messel, and ''raptor'' is a New Latin suffix used to indicate a predator (from ''rapere, to catch'') and in English it means ''bird of prey''. Specific epithet ''parvunguis'' is also Latin, coming from the word ''parvus'' which means small and feeble, while ''unguis'' means claw. The name refers to the fact that the specimen's claws are small in comparison to those of other raptors. Characteristics The genus ''Masillaraptor'' is different from all other known avian taxa. It possesses a combination of characters that distinguishes it from all others. 1. The beak is almost as long as the cranium itself, with equ ...

Life Restoration
Paleoart (also spelled palaeoart, paleo-art, or paleo art) is any original artistic work that attempts to depict prehistoric life according to scientific evidence. Works of paleoart may be representations of fossil remains or imagined depictions of the living creatures and their ecosystems. While paleoart is typically defined as being scientifically informed, it is often the basis of depictions of prehistoric animals in popular culture, which in turn influences public perception of and fuels interest in these animals. The word paleoart is also used in other informal sense, as a name for prehistoric art, most often cave paintings. Alternative concept of this term is the domain of archeological society. The term "paleoart"–which is a portmanteau of ''paleo'', the Ancient Greek word for "old", and "art"–was introduced in the late 1980s by Mark Hallett for art that depicts subjects related to paleontology, but is considered to have originated as a visual tradition in early 180 ...

Caracara Plancus
The crested caracara (''Caracara plancus'') is a bird of prey in the family Falconidae. It is found from the southern United States through Central and South America to Tierra del Fuego. It was formerly placed in the genus ''Polyborus''. Description The crested caracara has a total length of and a wingspan of . Its weight is , averaging in seven birds from Tierra del Fuego.''CRC Handbook of Avian Body Masses, 2nd Edition'' by John B. Dunning Jr. (Editor). CRC Press (2008), . Individuals from the colder southern part of its range average larger than those from tropical regions (as predicted by Bergmann's rule) and are the largest type of caracara. In fact, they are the second-largest species of falcon in the world by mean body mass, second only to the gyrfalcon. The cap, belly, thighs, most of the wings, and tail tip are dark brownish, the auriculars (feathers surrounding the ear), throat, and nape are whitish-buff, and the chest, neck, mantle, back, upper tail coverts, crissum ( ...

Psilopterus Lemoinei
''Psilopterus'' (Greek for "bare wing") is an extinct genus of phorusrhacid ("terror bird") from the Middle Oligocene to possibly the Late Pleistocene of Argentina and Uruguay. Compared to other phorusrhacids, members of the genus are both relatively gracile and diminutive, and include the smallest known species of terror bird: with the head raised ''P. bachmanni'' was in height and weighed about , while the largest members of the genus were only about . The birds resemble the modern cariama (''Cariama cristata''), except with a heavier build and considerably smaller wings. The strong morphological similarity between the claws of the predatory cariama and ''Psilopterus'', both of which are sharp, curved, and laterally compressed, may indicate they were used to strike prey. In contrast to the other, larger terror birds, Tonni and Tambussi also suggested ''Psilopterus'' could use their claws to climb trees, and could even fly, but this has been rejected in more recent literature.

Llallawavis Scagliai
''Llallawavis scagliai'' (magnificent bird of Scaglia) is a large, extinct predatory bird from Pliocene Argentina. Its fossil is the most complete fossil of a phorusrhacid (or "terror bird") yet found. Description The fossil, discovered in 2010 in sediment among the cliffs above La Estafeta beach in the lower part of the Playa Los Lobos Allo Formation, contains the complete palate, complete trachea, skull, voice box, and eye bones. The fossil shows ''L. scagliai'' was a medium-sized phorusrhacid around tall and lived in Argentina approximately 3.5 million years ago during the Pliocene The Pliocene ( ; also Pleiocene) is the epoch in the geologic time scale that extends from 5.333 million to 2.58

Phorusrhacidae
Phorusrhacids, colloquially known as terror birds, are an extinct clade of large carnivorous flightless birds that were one of the largest species of apex predators in South America during the Cenozoic era; their conventionally accepted temporal range covers from 62 to 0.1 million years ( Ma) ago. They ranged in height from . Their closest modern-day relatives are believed to be the seriemas. ''Titanis walleri'', one of the larger species, is known from Texas and Florida in North America. This makes the phorusrhacids the only known large South American predator to migrate north in the Great American Interchange that followed the formation of the Isthmus of Panama land bridge (the main pulse of the interchange began about 2.6 Ma ago; ''Titanis'' at 5 Ma was an early northward migrant). It was once believed that ''T. walleri'' became extinct in North America around the time of the arrival of humans, but subsequent datings of ''Titanis'' fossils provided no evidence for their surv ...

Cariama Cristata 1838 White Background
The red-legged seriema (''Cariama cristata''), also known as the crested cariama and crested seriema, is a mostly predatory terrestrial bird in the seriema family ( Cariamidae), included in the Gruiformes in the old paraphyletic circumscription but recently placed in a distinct order: Cariamiformes (along with three extinct families). The red-legged seriema is widely distributed in South America, occurring in central and eastern Brazil through eastern Bolivia and Paraguay to Uruguay and central Argentina (south to La Pampa). Like the black-legged seriema, farmers often use them as guard animals to protect poultry from predators and sometimes human intruders. Taxonomy The red-legged seriema was described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his ''Systema Naturae''. He coined the binomial name ''Palamedea cristata''. The red-legged seriema is now the only species placed in the genus ''Cariama'' that was introduced by the French zoologist Ma ...

Bathornis Grallator Restoration
''Bathornis'' ("tall bird") is an extinct lineage of birds related to modern day seriemas, that lived in North America about 37–20 million years ago. Like the closely related and also extinct phorusrhacids, it was a flightless predator, occupying predatory niches in environments classically considered to be dominated by mammals. It was a highly diverse and successful genus, spanning a large number of species that occurred from the Priabonian Eocene to the Burdigalian Miocene epochs. Description Though most material is highly incomplete, ''Bathornis'' is nonetheless known from a variety of skeletal elements: hindlimbs (most commonly tarso-metatarsals), forelimb elements (especially humeri), pelvises and skulls.Federico L. Agnolin (2009)"Sistemática y Filogenia de las Aves Fororracoideas (Gruiformes, Cariamae)"(PDF). Fundación de Historia Natural Felix de Azara: 1–79. ''Bathornis grallator'' is known from a mostly complete skeleton, including the skull, bearing a proportionall ...

Cariamiformes
Cariamiformes (or Cariamae) is an order of primarily flightless birds that has existed for over 60 million years. The group includes the family Cariamidae (seriemas) and the extinct families Phorusrhacidae, Bathornithidae, Idiornithidae and Ameghinornithidae. Though traditionally considered a suborder within Gruiformes, both morphological and genetic studies show that it belongs to a separate group of birds, Australaves, whose other living members are Falconidae, Psittaciformes and Passeriformes. This proposal has been confirmed by a 2014 study of whole genomes of 48 representative bird species. This analysis shows that the Cariamiformes are basal among extant Australaves, while falcons are next most basal; in combination with the fact that the two most basal branches of Afroaves (New World vultures plus Accipitriformes, and owls) are also predatory, it is inferred that the common ancestor of 'core landbirds' (Telluraves) was an apex predator. However, some researchers like Da ...

Danielsraptor Phorusrhacoides
''Danielsraptor'' (meaning "Michael Daniels's thief") is an extinct genus of masillaraptorid bird from the Early Eocene (Ypresian) Walton Member of the London Clay Formation in Essex, United Kingdom. The genus contains a single species, ''D. phorusrhacoides'', known from a partial skeleton. Discovery and naming The ''Danielsraptor'' fossil material was discovered in layers of the London Clay Formation (Walton Member), dated to the early Ypresian. This formation is located near Walton-on-the-Naze in Essex, England. The holotype, NMS.Z.2021.40.12, was collected in 1991 by Michael Daniels (who the taxon is named after). This specimen consists of a partial skeleton including the skull, vertebrae, fragmentary wing bones, elements of the pectoral girdle, pelvis, the majority of the legs, and various bone fragments still partially enclosed in matrix. An additional referred specimen, NMS.Z.2021.40.13, was found by Daniels in 1986. This specimen includes a partial sternum, right cor ...
