Thylacinus is a genus of extinct carnivorous marsupials in the family Thylacinidae. The only recent member was the thylacine, commonly also known as the Tasmanian tiger or Tasmanian wolf. The last known Tasmanian tiger was in the Beaumaris Zoo in Tasmania, eventually passing away in 1936. The earliest known member of the genus, Thylacinus macknessi appeared during the Early Miocene, around 16 million years ago, and was smaller than the modern thylacine, with a body mass of about 6.7–9.0 kilograms (14.8–19.8 lb). Thylacinus represented the only extant genus of the family after the beginning of the Pliocene around 5 million years ago. Over time members of the genus saw an increase in body mass and a greater adaption to hypercarnivory in their dental morphology.
Protarchaeopteryx is a genus of turkey-sized feathered theropod dinosaur from China. Known from the Jianshangou bed of the Yixian Formation, it lived during the early Aptian age of the Early Cretaceous, approximately 124.6 million years ago. It was probably a herbivore or omnivore, although its hands were very similar to those of small carnivorous dinosaurs. It appears to be one of the most basal members of the Oviraptorosauria, closely related to Incisivosaurus, or a taxon slightly less closely related to birds than oviraptorosaurs were.
Dermochelyidae is a family of turtles which has seven extinct genera and one extant genus, including the largest living sea turtles.
Jixiangornis is a genus of basal avialans from the Early Cretaceous. Like later avialans, it had no teeth, but it also had a long tail, unlike modern birds. Since teeth were still present in some more derived short-tailed avialans, Jixiangornis seems to have evolved its toothlessness independently of modern birds. The long forelimb indicates at least some aerial ability. Jixiangornis is currently known only from a single specimen, a complete but juvenile skeleton. The fossil was found in the Yixian Formation near Beipiao City, western Liaoning, China.
Ticinosuchus is an extinct genus of suchian archosaur from the Middle Triassic of Switzerland and Italy.
Guloninae is a subfamily of the mammal family Mustelidae distributed across Eurasia and the Americas. It includes martens and the fisher, tayra and wolverine. These genera were formerly included within a paraphyletic definition of the mustelid subfamily Mustelinae.
Bouliachelys is an extinct genus of sea turtle from Cretaceous Australia. It was originally described as a member of Protostegidae. In 2013 study it was considered to be a member of Dermochelyoidae, although later studies consider it as a protostegid again.
Atoposauridae is a family of crocodile-line archosaurs belonging to Neosuchia. The majority of the family are known from Late Jurassic to Early Cretaceous marine deposits in France, Portugal, and Bavaria in southern Germany. The discovery of the genus Aprosuchus, however, extends the duration of the lineage to the end of the Cretaceous in Romania.
Isisfordia is an extinct genus of crocodyliform closely related to crocodilians that lived in Australia during the Middle Cretaceous (Albian–Cenomanian).
Fugusuchus is an extinct genus of archosauriform, probably the basal-most member of the family Erythrosuchidae. The genus is known from a single fossil from the middle Early Triassic Heshanggou Formation in Shanxi, China. The partial skeleton consists of an incomplete skull, parts of the right forelimb, and an intercentrum. The skeleton, known as GMB V 313, is currently in the Geological Museum of China in Beijing.
Brachylophosaurini is a tribe of saurolophine hadrosaurs with known material being from N. America and potentially Asia. It contains at least four taxa; Acristavus, Brachylophosaurus, Maiasaura, and Probrachylophosaurus. A hadrosaur from the Amur river, Wulagasaurus, might be a member of this tribe, but this is disputed. The group was defined by Terry A. Gates and colleagues in 2011.
Plesiogulo is a genus of prehistoric carnivore that lived from Miocene to Pliocene of Africa, Eurasia and North America. An ancestral relationship to the wolverine was once suggested, but it is no longer considered likely. However, some authorities still consider it a member of the Guloninae.
The volatilome contains all of the volatile metabolites as well as other volatile organic and inorganic compounds that originate from an organism, super-organism, or ecosystem. The atmosphere of a living planet could be regarded as its volatilome. While all volatile metabolites in the volatilome can be thought of as a subset of the metabolome, the volatilome also contains exogenously derived compounds that do not derive from metabolic processes, therefore the volatilome can be regarded as a distinct entity from the metabolome. The volatilome is a component of the 'aura' of molecules and microbes that surrounds all organisms.
Machaeroidinae ("dagger-like") is an extinct subfamily of carnivorous sabre-toothed placental mammals from extinct family Oxyaenidae, that lived from the early to middle Eocene of Asia and North America. Traditionally classified as hyaenodonts, this group is now classified as a member of the family Oxyaenidae.
Santanmantis is an extinct genus of mantises, the sole genus in the family Santanmantidae. The only species, Santanmantis axelrodi, is known from the Crato Formation of Brazil, dating to the late Aptian stage of the Early Cretaceous. It is amongst the most primitive known lineages of mantis. Like other mantises, the forelegs are modified into spined raptorial appendages. When describing a new specimen in 2017, Hörnig, Haug and Haug proposed that the second set of legs also had spines similar to the forelegs, and also served a raptorial function, but that they were not visible in the fossil due to being broken off. However a response to this paper criticised this assumption, finding that it had little evidence from the fossil itself or from living mantises.
The Naobaogou Formation is a geological formation in the Daqing Mountains of China. It is likely of Lopingian age. It consists of three rhythms of sediment, labelled members I-III primarily of purple siltstone, but each with a thick basal conglomerate bed. It is notable for its fossil content, producing one of the most diverse Late Permian vertebrate faunas outside Russia and South Africa.

She is the Founder and Executive Director of The Sloth Conservation Foundation and author of the book Sloths: Life in the Slow Lane with photographs by award-winning wildlife photographer Suzi Eszterhas.
TheSloth Conservation Foundation (SloCo) is a non-profit organisation based in Costa Rica that is dedicated to the protection of sloths living in wild and human-modified habitats through research, education and community-based conservation. SloCo was founded in 2017 by sloth researcher Dr. Rebecca Cliffe.
Menefeeceratops is a genus of ceratopsid dinosaur from the Menefee Formation in New Mexico, United States. It is potentially the oldest known member of the ceratopsids, as well as the centrosaurine subfamily, related to animals including Yehuecauhceratops and Crittendenceratops. The type and only species is Menefeeceratops sealeyi, known from a partial, non-articulated skeleton.
Jiufengia is an extinct genus of therocephalian in the family Akidnognathidae. It is known from a single species, Jiufengia jiai, from the Late Permian Naobaogou Formation in China.
