Calyptommatus is a genus of Brazilian lizards in the family Gymnophthalmidae. [1]
The genus shows extreme reduction of hind limbs and absence of fore limbs. Also prefrontals, frontals, supraoculars, and frontoparietals are absent. [1]
There are five species: [1]
Phelsuma is a large genus of geckos in the family Gekkonidae. Species in the genus Phelsuma are commonly referred to as day geckos.
Gymnophthalmidae is a family of lizards with at least 250 species, sometimes known commonly as spectacled lizards or microteiids. They are called "spectacled" because of their transparent lower eyelids, which allow them to still see with closed eyes. As in most lizards, except geckos, these eyelids are movable. The Alopoglossidae have been recently moved from this family.
Lerista is a diverse genus of skinks endemic to Australia, commonly known as sliders.
Procellosaurinus is a genus of lizards in the family Gymnophthalmidae. They are endemic to Brazil.
Virola is a genus of flowering plants in the nutmeg family, Myristicaceae. It includes medium-sized trees native to rainforests of the tropical Americas, ranging from southern Mexico to Bolivia and southern Brazil. Species are known commonly as epená, patricá, or cumala. They have glossy, dark green leaves and clusters of tiny yellow flowers, and may emit a pungent odor.
The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family of frogs. The 683 species are in 57 genera and 11 subfamilies.
The Raphinae are a clade of extinct flightless birds formerly called didines or didine birds. They inhabited the Mascarene Islands of Mauritius and Rodrigues, but became extinct through hunting by humans and predation by introduced non-native mammals following human colonisation in the 17th century. Historically, many different groups have been named for both the dodo and the Rodrigues solitaire, not all grouping them together. Most recently, it is considered that the two birds can be classified in Columbidae, often under the subfamily Raphinae. The first person to suggest a close affinity to the doves was Johannes Theodor Reinhardt, whose opinions were then supported by Hugh Edwin Strickland and Alexander Gordon Melville.
Paulo Emilio Vanzolini was a Brazilian scientist and music composer. He was best known for his samba compositions, including the famous "Ronda", "Volta por Cima", and "Boca da Noite", and for his scientific works in herpetology. He is considered one of the greatest samba composers from São Paulo. Until his death, he still conducted research at the University of São Paulo (USP).
Dendrophryniscus is a genus of true toads in the family Bufonidae, sometimes known as tree toads. They are endemic to the Atlantic Forest of Brazil.
The Rodrigues parrot or Leguat's parrot is an extinct species of parrot that was endemic to the Mascarene island of Rodrigues. The species is known from subfossil bones and from mentions in contemporary accounts. It is unclear to which other species it is most closely related, but it is classified as a member of the tribe Psittaculini, along with other Mascarene parrots. The Rodrigues parrot bore similarities to the broad-billed parrot of Mauritius, and may have been related. Two additional species have been assigned to its genus, based on descriptions of parrots from the other Mascarene islands, but their identities and validity have been debated.
The Rodrigues starling is an extinct species of starling that was endemic to the Mascarene island of Rodrigues. Its closest relatives were the Mauritius starling and the hoopoe starling from nearby islands; all three are extinct and appear to be of Southeast Asian origin. The bird was only reported by French sailor Julien Tafforet, who was marooned on the island from 1725 to 1726. Tafforet observed it on the offshore islet of Île Gombrani. Subfossil remains found on the mainland were described in 1879, and were suggested to belong to the bird mentioned by Tafforet. There was much confusion about the bird and its taxonomic relations throughout the 20th century.
Eopteranodon is a genus of tapejarid pterosaur from the Aptian-age Lower Cretaceous Yixian Formation of Beipiao City, Liaoning, China. The genus was named in 2005 by paleontologists Lü Junchang and Zhang Xingliao. The type species is Eopteranodon lii.
Stenocercus is a genus of South American lizards, commonly called whorltail iguanas, of the family Tropiduridae. This genus has 80 valid described species.
Cylindraspis is a genus of recently extinct giant tortoises. All of its species lived in the Mascarene Islands in the Indian Ocean and all are now extinct due to hunting and introduction of non-native predators.
Amphisbaena is a genus in the family Amphisbaenidae, commonly known as worm lizards. Over 100 species are placed in this diverse genus.
Pteranodontoidea is an extinct clade of ornithocheiroid pterosaurs from the Early to Late Cretaceous of Asia, Africa, Europe, North America and South America. It was named by Alexander Wilhelm Armin Kellner in 1996. In 2003, Kellner defined the clade as a node-based taxon consisting of the last common ancestor of Anhanguera, Pteranodon and all its descendants. The clade Ornithocheiroidea is sometimes considered to be the senior synonym of Pteranodontoidea, however it depends on its definition. Brian Andres in his analyses, converts Ornithocheiroidea using the definition of Kellner (2003) to avoid this synonymy.
Ornithocheiromorpha is a group of pterosaurs within the suborder Pterodactyloidea. Fossil remains of this group date back from the Early to Late Cretaceous periods, around 140 to 92.5 million years ago. Ornithocheiromorphs were discovered worldwide except Antarctica, though most genera were recovered in Europe, Asia and South America. They were the most diverse and successful pterosaurs during the Early Cretaceous, but throughout the Late Cretaceous they were replaced by better adapted and more advanced pterosaur species such the pteranodontids and azhdarchoids. The Ornithocheiromorpha was defined in 2014 by Andres and colleagues, and they made Ornithocheiromorpha the most inclusive clade containing Ornithocheirus, but not Pteranodon.
Amerotyphlops is a genus of snakes in the family Typhlopidae.
Calyptommatus nicterus is a species of Squamata in the family spectacled tegus. They are found in the Neotropics of Brazil. They rely on running to move around. This is species of lizard in the family Gymnophthalmidae. It is endemic to Brazil.
