Viverridae is a family of small to medium-sized, feliform mammals. The viverrids comprise 33 species placed in 14 genera. This family was named and first described by John Edward Gray in 1821. Viverrids occur all over Africa, southern Europe, and South and Southeast Asia, across the Wallace Line.
Gavialidae is a family of large semiaquatic crocodilians with elongated, narrow snouts. Gavialidae consists of two living species, the gharial and the false gharial, both occurring in Asia. Many extinct members are known from a broader range, including the recently extinct Hanyusuchus. Gavialids are generally regarded as lacking the jaw strength to capture the large mammalian prey favoured by crocodiles and alligators of similar size so their thin snout is best used to catch fish, however the false gharial has been found to have a generalist diet with mature adults preying upon larger vertebrates, such as ungulates.
Zapsalis is a genus of dromaeosaurine theropod dinosaurs. It is a tooth taxon, often considered dubious because of the fragmentary nature of the fossils, which include teeth but no other remains.
Herpestes is a genus within the mongoose family Herpestidae. Several species in the family are known as slender mongooses. It is the type genus of the family, and comprises 5-6 living species, each with several subspecies. Fossil remains of three prehistoric species were excavated in France, and described in 1853.
Baronia brevicornis, commonly known as the short-horned baronia, is a species of butterfly in the monotypic genus Baronia and is placed in a subfamily of its own, the Baroniinae, a sister group of the remainder of the swallowtail butterflies. It is endemic to a very small area of Mexico, where the distribution is patchy and restricted.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1999.
George Thomas Bethune-Baker was an English entomologist who specialised in Lepidoptera, especially those in the family Lycaenidae of butterflies.

Navajosuchus is an extinct genus of alligatorine crocodylian. Its fossils have been found in the Paleocene-age Nacimiento Formation of the San Juan Basin, New Mexico. It was named in 1942 by Charles C. Mook, and the original type species was N. novomexicanus. N. novomexicanus was based on AMNH 5186, a partial skull collected in 1913. Later research showed that Navajosuchus novomexicanus was the same as the earlier-named Allognathosuchus mooki. However, A. mooki does not belong to the genus Allognathosuchus, and so the name of the crocodilian becomes Navajosuchus mooki. Under whichever name is used, this animal would have been a generalized predator of the Nacimiento floodplains. It was the most common Nacimiento Formation crocodilian, found in both the Puercan and Torrejonian faunal assemblages.
Stangerochampsa is an extinct genus of alligatorid, possibly an alligatorine or a stem-caiman, from the Late Cretaceous of Alberta. It is based on RTMP.86.61.1, a skull, partial lower jaws, and partial postcranial skeleton discovered in the late Campanian–early Maastrichtian-age Horseshoe Canyon Formation. Stangerochampsa was described in 1996 by Wu and colleagues. The type species is S. mccabei. The generic name honors the Stanger family, the owners of the ranch where the specimen was found, and the species name honors James Ross McCabe, who discovered, collected, and prepared it. Stangerochampsa is described as "small to medium–sized"; the type skull is 20.0 centimetres (7.9 in) long from the tip of the snout to the occipital condyle, and is 13.0 centimetres (5.1 in) wide at its greatest, while the thigh bone is 14.2 centimetres (5.6 in) long. It had heterodont dentition, with large crushing teeth at the rear of the jaws.
Tricuspisaurus is an extinct genus of reptile originally described as a trilophosaurid; it was later considered likely to be a procolophonid, but recent analyses have affirmed the original classification. Fossils are known from the Ruthin Quarry in Glamorgan, Wales, one of several Late Triassic to Early Jurassic British fissure deposits. Like some trilophosaurs, it has an edentulous, or toothless beak. Tricuspisaurus gets its name from its heterodont dentition, which includes tricuspid teeth, or teeth with three cusps. The type species, T. thomasi, was named in 1957 along with the possible trilophosaur Variodens inopinatus from Somerset, England.
Voltinia dramba is a fossil metalmark butterfly, found in pieces of amber in the Dominican Republic on the island of Hispaniola in 2004. The butterfly, belonging to the extant genus Voltinia, is the first species to be taxonomically described from amber and the first true fossil of an adult riodinid. Five specimens, all females, were found in pieces of amber from the resin of the extinct leguminous tree Hymenaea protera. Also, the genus Voltinia contains nine heterogeneous species that range from Mexico to Brazil. The fossil appeared to be 15-25 million years old and it's a holotype female fossil. However, the fossil's origin may be unknown, it is ingrained in highly polymerized Dominican amber.
Sinopa is an extinct genus of placental mammals from extinct family Sinopidae within extinct order Hyaenodonta, that lived in North America and Asia from the early to middle Eocene.
"Crocodylus" affinis is an extinct species of crocodyloid from the Eocene of Wyoming. Fossils were first described from the Bridger Formation by American paleontologist Othniel Charles Marsh in 1871. Marsh described the species, along with every other species of crocodyloid in the Bridger Formation, under the genus Crocodylus. The known specimen of "Crocodylus" affinis is a skull found at Grizzly Buttes, Wyoming, measuring 13 inches in length on the upper surface. Recent phylogenetic studies of crocodyloids show that "C." affinis is not a species of Crocodylus, but a genus has not yet been erected to include the species. Other Bridger species such as Crocodylus clavis and Brachyuranochampsa zangerli have been synonymized with "C." affinis.
Eocoronidae is an extinct family of insects from the Carnian age of the Triassic period. It was established in 1981 by the Australian entomologist Norman Tindale. At present, it contains only one species and genus: Eocorona iani.
Pronophilina is a Neotropical subtribe of butterflies of the subfamily Satyrinae. They are a species-rich group with highest diversity in the tropical and subtropical mountains, especially the Andes. Before 1970, they were poorly studied, but recent interest has resulted in high rates of species description from previously unexplored mountain ranges. However, there is still a lack of knowledge on their biology and ecology. Their relationship to other groups of Satyrine butterflies and their complex patterns of speciation within and among mountain ranges have led to several biogeographic discussions.
Lophocetus is an extinct genus of dolphin belonging to the clade Delphinida that is known from late Miocene (Tortonian) marine deposits in California and Maryland. Although usually placed in Kentriodontidae, recent studies have found it only distantly related to Kentriodon.
Florissantia is an extinct monotypic genus of planthopper in the dictyopharid subfamily Dictyopharinae. The single species, Florissantia elegans, was described by Samuel Hubbard Scudder (1890) from fossils found in the Florissant Formation of Colorado.
Urva is a genus comprising the Asian mongooses within the mongoose family Herpestidae. Species in the genus were formerly classified in the genus Herpestes, which is now thought to comprise exclusively African mongooses; phylogenetic evidence indicates that the Asian mongooses form a monophyletic group and had an Asian common ancestor. Urva forms a clade with Xenogale and Atilax, while Herpestes forms a clade with all other African mongoose species.
