Xenokeryx ("strange horn" in Greek) is an extinct genus of ruminant known from the Miocene of Europe.
 The type species, Xenokeryx amidalae, was recovered from central Spain and bears a unique T-shaped protrusion from the top of the head.
 The specific epithet "amidalae" is in reference to the character Padmé Amidala from the "Star Wars" films "due to the striking resemblance that the occipital appendage of "Xenokeryx" bears to one of the hairstyles that the aforementioned character shows in "" feature film."
Thalassictis is an extinct genus of terrestrial carnivore in the family Hyaenidae that lived in Asia during the Middle to Late Miocene and in Europe and North Africa during the Late Miocene.
Ysengrinia is an extinct genus of large, mostly carnivorous bone-crushing mammals known as bear dogs, of the family Amphicyonidae found in Europe during the Late Oligocene and Early Miocene, in North America during the Early Miocene, and possibly in southwestern Africa during the Early Miocene.
Dorcatherium is an extinct genus of tragulid ruminant which existed in Europe, East Africa and the Siwaliks during the Miocene and Pliocene.
Star Wars: Thrawn (also known simply as Thrawn) is a "Star Wars" novel by Timothy Zahn, published on April 11, 2017 by Del Rey Books.
 It chronicles the origins of Grand Admiral Thrawn, a popular character originating from the "Star Wars Legends" line of works, which were declared non-canon to the franchise after Lucasfilm redefined "Star Wars" continuity in April 2014.
 The novel was announced in July 2016 alongside news that the character Thrawn would be reintroduced into the "Star Wars" franchise on the 3D CGI animated television series "Star Wars Rebels".
Stegotetrabelodon is an extinct genus of primitive elephant with gomphothere-like anatomical features from the Late Miocene to Early Pliocene of Africa and Eurasia.
 The type species is "S. syrticus" of late Miocene Africa, which reached roughly 4 m (13.1 ft) in shoulder height.
 The other unequivocally recognized species is "S. orbus", also of late Miocene Africa.
 Other species outside of Africa are questionably placed in this genus, including teeth from Late Miocene Hungary and Iran originally described as being of the "Mastodon" subgenus "Bunolophodon", Chinese specimens originally described as being also of "Mastodon", as well as of "Tetralophodon" and "Stegodon", and a species from the late Miocene-aged Dokh Pathan Formation in Pakistan, "S. maluvalensis".
Padmé Amidala (born Padmé Naberrie) is a fictional character in the "Star Wars" franchise, appearing in the prequel trilogy portrayed by actress Natalie Portman.
 She served as the Princess of Theed and later Queen of Naboo.
 After her reign, she became a senator in the Galactic Senate, an anti-war movement spokesperson, and co-founder of the opposition-faction that later emerged as the Rebel Alliance.
 She was secretly married to the Jedi Anakin Skywalker, and the biological mother of Luke Skywalker and Leia Organa, which makes her the mother-in-law of Han Solo, and the grandmother of Kylo Ren.
Mionothropus is an extinct genus of nothrotheriine nothrotheriid sloth which existed in Peru in the western Amazon basin, during the late Miocene (Huayquerian age).
 It is known from the holotype LACM 4609/117533, which includes cranial remains, recovered from the riverbank deposits of the Iñapari Formation in the Río Acre region, were originally assigned to "Nothropus priscus".
 It was first named by Gerardo De Iuliis, Timothy J. Gaudin and Matthew J. Vicars in 2011 and the type species is "Mionothropus cartellei".
 The generic name is derived from "Mio", is a reference to the Miocene provenance of the holotype, and "nothropus" refers to the initial allocation of the holotype to this genus from the South American Pleistocene.
 The specific name honours Dr. Castor Cartelle.
Afrotragulus is an extinct genus of tragulid ruminant which existed in Kenya during the early Miocene period.
 It contains the species "Afrotragulus moruorotensis" and "Afrotragulus parvus", formerly classified in genus "Dorcatherium".
Centenariosuchus is an extinct genus of caimanine crocodylian known from the Miocene of the Panama Canal Zone of Panama.
 It contains a single species, Centenariosuchus gilmorei, that was named in 2013 in honor of the upcoming centennial anniversary of the digging of the Panama Canal.
 Two fossil specimens consisting of skull fragments were found in the Early to Middle Miocene Cucaracha Formation in 2009 and 2011, and may belong to a single individual.
 The species is diagnosed by a combination of skull features that it shares with basal caimans like "Tsoabichi", "Eocaiman", "Culebrasuchus", and the living genus "Paleosuchus", as well as more derived caimans such as those in the genus "Caiman".
 One feature that distinguishes "Centenariosuchus" from all other caimans is the straight outer margin of a hole on the underside of the skull called the suborbital fenestra.
 According to one phylogenetic analysis of caimanine relationships, "Centenariosuchus" falls within a clade or evolutionary grouping of caimans that includes the very large and highly specialized forms "Purussaurus" and "Mourasuchus", known from the Miocene of South America"."
