Coprinites
''Coprinites'' is an extinct monotypic genus of gilled fungus in the Agaricales family Agaricaceae. At present it contains the single species ''Coprinites dominicana''. The genus is solely known from the early Miocene, Burdigalian stage, Dominican amber deposits on the island of Hispaniola. ''Coprinites'' is one of only four known agarics fungus species known in the fossil record and the first of three to be described from Dominican amber. History and classification The genus is known only from the single holotype "''AF-9-11''", a single fruiting body, mushroom, specimen currently residing in the Poinar collections maintained by the University of California, Berkeley. The specimen was collected from the La Toca amber mine, northeast of Santiago de los Caballeros, in the Cordillera Septentrional area of the Dominican Republic. It was first studied by Dr. George Poinar of the UC, Berkeley and Dr. Rolf Singer from the Field Museum of Natural History in Chicago, Illinois. Po ...

Tetraponera Klebsi GZG-BST04671 Holotype Profile
''Tetraponera'' is a genus of ants in the subfamily Pseudomyrmecinae that are commonly known as slender ants and are characterized by their arboreal nature and slender bodies. The 96 described species of ''Tetraponera'' all of which live in hollow structures of plants and trees, such as thorns or branches; these hosts are known as myrmecophytes. ''Tetraponera'' species are closely related to the New World genus of ants ''Pseudomyrmex'', but differ in their relationships with host plants. Mutualisms and behaviour ''Tetraponera'' species are generally defined by the myrmecophytes they inhabit and the mutualistic relationship they share. These host plants always have hollow thorns or branches in which the ants can live and form a colony. Also, the myrmecophytes provide energy rich food sources such as extrafloral nectar and/or food bodies. All ''Tetraponera'' species have gut symbionts that allow them to digest amino acid-deficient food provided by their host plants; these gut b ...

Anatotitan BW
''Edmontosaurus annectens'' (meaning "connected lizard from Edmonton") is a species of flat-headed and duck-billed ( hadrosaurid) dinosaur from the very end of the Cretaceous Period, in what is now North America. Remains of ''E. annectens'' have been preserved in the Frenchman, Hell Creek, and Lance Formations. All of these formations are dated to the late Maastrichtian stage of the Late Cretaceous Period, representing the last three million years before the extinction of the dinosaurs (between 68 and 66 million years agoHoltz, Thomas R. Jr. (2012) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'Winter 2011 Appendix./ref>). ''E. annectens'' is also found in the Laramie Formation, and magnetostratigraphy suggests an age of 69-68 Ma for the Laramie Formation.*Hicks, J.F., Johnson, K.R., Obradovich, J.

Michael K
''Life & Times of Michael K'' is a 1983 novel by South African-born writer J. M. Coetzee. The novel won the Booker Prize for 1983. The novel is a story of a man named Michael K, who makes an arduous journey from Cape Town to his mother's rural birthplace, amid a fictitious civil war during the apartheid era, in the 1970-80s. Plot summary The novel is split into three parts. The novel begins with Michael K, a poor man with a cleft lip who has spent his childhood in institutions and works as a gardener in Cape Town. Michael tends to his mother who works as a domestic servant to a wealthy family. The country descends into civil war and martial law is imposed, and Michael's mother becomes very sick. Michael decides to quit his job and escape the city to return his mother to her birthplace, which she says was Prince Albert. Michael finds himself unable to obtain the proper permits for travel out of the city so he builds a shoddy rickshaw to carry his mother, and they go on their ...

Agilisaurus2
''Agilisaurus'' (; 'agile lizard') is a genus of ornithischian dinosaur from the Middle Jurassic Period of what is now eastern Asia. It was about 3.5–4 ft (1.2-1.7 m) long, 2 ft (0.6 m) in height and 40 kg in weight. It has leaf-shaped teeth that were well-adapted to their abrasive, plant-based diets. Most surprisingly, the wavy enamel of the teeth of ''A. louderbacki'' and all other ornithopods, presumably to make it more resistant to wear, was previously thought to be exclusive to the hadrosaurs. This is also the case for ''Changchunsaurus parvus''.Jun Chen, Aaron R. H. LeBlanc, Liyong Jin, Timothy Huang, Robert R. Reisz.

Edmontosaurus
''Edmontosaurus'' ( ) (meaning "lizard from Edmonton") is a genus of hadrosaurid (duck-billed) dinosaur. It contains two known species: ''Edmontosaurus regalis'' and ''Edmontosaurus annectens''. Fossils of ''E. regalis'' have been found in rocks of western North America that date from the late Campanian Stage (stratigraphy), stage of the Cretaceous Period (geology), Period 73 million years ago, while those of ''E. annectens'' were found in the same geographic region but in rocks dated to the end of the Maastrichtian stage of the Cretaceous, 66 million years ago. ''Edmontosaurus'' was one of the last non-bird, avian dinosaurs, and lived alongside dinosaurs like ''Triceratops'', ''Tyrannosaurus'', ''Ankylosaurus'', and ''Pachycephalosaurus'' shortly before the Cretaceous–Paleogene extinction event. ''Edmontosaurus'' included some of the largest hadrosaurid species, with ''E. annectens'' measuring up to in length and weighing around in average asymptotic body mass, althoug ...

Monte Bolca
Monte Bolca is a lagerstätte near Verona, Italy that was one of the first fossil sites with high quality preservation known to Europeans, and is still an important source of fossils from the Eocene. Geology Monte Bolca was uplifted from the Tethys Ocean floor during the formation of the Alps, in two stages: one 24 million years ago, and one between 30 and 50 million years ago. The entire formation consists of of limestone, all of which contain fossils, but interspersed in which are the lagerstätte layers that contain the highly preserved specimens. Within these layers, the fish and other specimens are so highly preserved that their organs are often completely intact in fossil form, and even the skin colorWilliams, MattTaphonomy of Monte Bolca University of Bristol can sometimes be determined. The normal rearrangement of the specimens caused by mud-dwelling organisms in the layer before it turned to stone has been avoided—it is assumed that the mud in question was low in ox ...
