Mecochirus longimanatus is an extinct species of lobster-like decapod crustacean from the Jurassic of Europe.
A chordate is a deuterostomic animal belonging to the phylum Chordata. All chordates possess, at some point during their larval or adult stages, five distinctive physical characteristics (synapomorphies) that distinguish them from other taxa. These five synapomorphies are a notochord, a hollow dorsal nerve cord, an endostyle or thyroid, pharyngeal slits, and a post-anal tail. The name "chordate" comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate body plan structuring and movements. Chordates are also bilaterally symmetric, have a coelom, possess a closed circulatory system, and exhibit metameric segmentation.
A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the fossil record.
Felidae is the family of mammals in the order Carnivora colloquially referred to as cats. A member of this family is also called a felid. The term "cat" refers both to felids in general and specifically to the domestic cat.
Panthera is a genus within the family Felidae that was named and described by Lorenz Oken in 1816 who placed all the spotted cats in this group. Reginald Innes Pocock revised the classification of this genus in 1916 as comprising the tiger, lion, jaguar, and leopard on the basis of common features of their skulls. Results of genetic analysis indicate that the snow leopard also belongs to the genus Panthera, a classification that was accepted by IUCN Red List assessors in 2008.
Gastropods, commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
Acipenser is a genus of sturgeons. With 17 living species, it is the largest genus in the order Acipenseriformes. The genus is paraphyletic, containing all sturgeons that do not belong to Huso, Scaphirhynchus, or Pseudoscaphirhynchus, with many species more closely related to the other three genera than they are to other species of Acipenser. They are native to freshwater and estuarine systems of Eurasia and North America, and most species are threatened. Several species also known to enter near-shore marine environments in the Atlantic, Arctic and Pacific oceans.
Chuanjiesaurus is a genus of sauropod dinosaurs from the middle Jurassic Period. They lived in what is now China. The type species, Chuanjiesaurus anaensis, was first described by Fang, Pang, Lü, Zhang, Pan, Wang, Li and Cheng in 2000. Fossils of the species were found in the village of Chuanjie, Lufeng County, Yunnan Province, and are named after the location where the fossils were discovered. Holtz gave a length of 25 meters.
Macrochelys is a genus of very large freshwater turtles in the family Chelydridae, native to the Southeastern and Midwestern United States. Only a single extant species was recognized until 2014, when a study divided it into two, or possibly three species. These turtles are easily recognized by three distinct dorsal ridges with raised spikes.
Cyatholipidae is a family of spiders first described by Eugène Simon in 1894. Most live in moist montane forest, though several species, including Scharffia rossi, live in dry savannah regions. They occur in Africa, including Madagascar, New Zealand and Australia, and one species in Jamaica. Most members of this family hang beneath sheet webs. Fossil species occur in the Eocene aged Bitterfield and Baltic Ambers, suggesting a wider geographic distribution in the past.
Manouria is a genus of tortoises in the family Testudinidae. The genus was erected by John Edward Gray in 1854.
Mecochirus is an extinct genus of lobster-like decapod crustaceans, containing 17 species. The Maxberg Specimen of Archaeopteryx was initially assigned to the type species, Mechocirus longimanatus before it was realised that it belonged to Archaeopteryx lithographica.
Qianichthyosaurus is an extinct genus of ichthyosaur from the Ladinian and Carnian stages of the Late Triassic epoch. Its fossils have been found in southeastern China, in Carnian rocks of the Falang Formation near Huangtutang, Guizhou. The type species is Qianichthyosaurus zhoui, named by Chun Li in 1999. A second species, Qianichthyosaurus xingyiensis, was named from older (Ladinian) deposits in the Falang Formation in 2013 by Pengfei Yang and colleagues. Complete Qianichthyosaurus fossils are common in the Xiaowa Formation, with both juveniles and pregnant specimens being known; its larger contemporaries, Guizhouichthyosaurus and Guanlingsaurus, are rarer.
Erymidae is a family of decapod crustaceans known only from fossils. They survived for 100 million years, from the Permo-Triassic boundary to the Albian. Eleven genera are recognised:
Homo gautengensis is a species name proposed by anthropologist Darren Curnoe in 2010 for South African hominin fossils otherwise attributed to H. habilis, H. ergaster, or, in some cases, Australopithecus or Paranthropus. The fossils assigned to the species by Curnoe cover a vast temporal range, from about 1.8 million years ago to potentially as late as 0.8 million years ago, meaning that if the species is considered valid, H. gautengensis would be both one of the earliest and one of the longest lived species of Homo.
Iaceornis is a prehistoric marine bird genus endemic to North America during the Late Cretaceous living about 83.5 mya. It is known from a single fossil specimen found in Gove County, Kansas (USA), and consisting of a partial skeleton lacking a skull.
Palaeomedusa testa is an extinct species of thalassochelydian turtle from the Tithonian of the Late Jurassic. It was first described by the German palaeontologist Christian Erich Hermann von Meyer in 1860. It is the only species classified under the genus Palaeomedusa.
Qantas is a genus of trematosauroid temnospondyl from the Early Triassic. Fossils have been found from the Kamennyi Yar Formation in Borsky District, Samara Oblast. The type species Qantas samarensis was named in 2012 and placed in the family Benthosuchidae, as it was viewed as a close relative of Benthosuchus. The subfamily Qantasinae was established to include Qantas, and possibly the genus Tirraturhinus. Qantas is named after the Australian airline Qantas, which supported the original study of the fossils.
Vulpes skinneri is a species of extinct fox in the genus Vulpes from the early Pleistocene, identified based on fossil remains dated to about 2 million years ago. The species is known from a single partial skeleton discovered in the Malapa Fossil Site at the Cradle of Humankind World Heritage Site in South Africa and is associated with the fossil hominin remains of Australopithecus sediba. The fossils have been dated to between 1.977 and 1.980 million years ago. Hartstone-Rose and colleagues described the remains as a newly discovered species of fox, which they named skinneri after the African mammalogist John Skinner.
Tasbacka is an extinct genus of sea turtle containing several species.
Hypericum holyi is an extinct species of the genus Hypericum that was present from the Lower Miocene to the Upper Miocene. Fossil seeds of the species have been found in Central Europe in general and Central Jutland, Denmark, in particular.
