Mazzaella (conodont)
''Mazzaella'' is an extinct genus of Late Triassic ozarkodinid conodonts in the family Gondolellidae. They are found in mid- Julian sediments of the Tethys Ocean, including strata in Europe (Germany, Hungary, Italy) and Turkey. The type species of ''Mazzaella'', ''Mazzaella carnica'', was originally designated as ''Epigondolella carnica'' Krystyn (1975). It has been used as an index fossil, defining the middle of three Julian conodont biozones according to a 2018 update to Tethyan conodont biostratigraphy. The genus also includes a rarer species, ''Mazzaella baloghi'', originally ''Metapolygnathus baloghi'' Kovacs (1977). ''Mazzaella'' appears to be a descendant of ''Metapolygnathus ( Quadralella)'' ''auriformis''. Relative to ''Metapolygnathus'', ''Mazzaella'' has a moderately elongated free blade and strong platform nodes. The platform is broader and the free blade is proportionally longer in ''M. baloghi'', relative to ''M. carnica''. Although its overall shape is similar to ...

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...

Metapolygnathus
''Metapolygnathus'' is an extinct genus of platform conodonts. Synonyms ''Mazzaella (conodont), Mazzaella'' is a new genus that also includes ''Metapolygnathus baloghi'' Kovacs (1977). Use in stratigraphy The top of the Carnian or the base of the Norian stages (Late Triassic) begin at the base of the conodont biozones of ''Metapolygnathus communisti'' and ''Metapolygnathus primitius''. A List of Global Boundary Stratotype Sections and Points, global reference profile for the base (a GSSP) had in 2009 not yet been appointed.

Natural History Of Hungary
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...
