Acteosaurus
''Acteosaurus'' is an extinct genus of aquatic lizard that lived in the upper Cretaceous period. Its species, ''A. tommasinii'' and ''A. crassicostatus'', were described in 1860 and 1993. Though ''A. crassicostatus'' is probably a junior synonym for '' Adriosaurus suessi'', ''A. tommasinii'' was found to be similar to coniasaurs, mosasauroids, and a sister taxon to modern snakes in 2010. Etymology The primary portion of ''Acteosaurus name comes from Actaeon (; Greek: ), a famous Theban hero who was hunted and killed by the goddess Artemis. The second part of the name is the Greek word ' (), which means " lizard" or " reptile". The type species was named after the botanist Muzio Giuseppe Spirito de Tommasini (1794—1879), the Podestà—or magistrate—of Trieste under the Habsburgs. Taxonomy As a genus, Acteosaurus was described in 1860 by German paleontologist Christian Erich Hermann von Meyer. There exist two known species of Acteosaurus called ''A. tommasi ...

Adriosaurus
''Adriosaurus'' is an extinct genus of squamate which lived in what is now Slovenia and other parts of Europe during the Late Cretaceous. It was snake-like and grew up to in length. This is the first fossil record of vestigial limbs in lizards. It lost its manus and forearm completely in order to elongate its axial skeleton. These unique anatomical features led to discussions of the evolutionary patterns of limb reduction in Squamata.Alessandro Palci and Michael W. Caldwell. 2007. Vestigial Forelimbs and Axial Elongation in a 95 Million-Year-Old Non-Snake Squamate. Journal of Vertebrate Paleontology Vol. 27, No. 1. pp. 1-7 ''Adriosaurus'' includes three species: ''A. microbrachis'' (“micro”, meaning small, and “brachis”, meaning arm, referring to the vestigial forelimb composed of only the humerus), ''A skrbinensis'' (named after the location where they found the fossil, Skrbina, northwest of Komen, Slovenia) and ''A. suessi''.

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hero
A hero (feminine: heroine) is a real person or a main fictional character who, in the face of danger, combats adversity through feats of ingenuity, courage, or Physical strength, strength. Like other formerly gender-specific terms (like ''actor''), ''hero'' is often used to refer to any gender, though ''heroine'' only refers to women. The original hero type of classical epics did such things for the sake of glory (honor), glory and honor. post-classical history, Post-classical and modern history, modern heroes, on the other hand, perform great deeds or selfless acts for the common good instead of the classical goal of wealth, pride, and fame. The antonym of ''hero'' is ''villain''. Other terms associated with the concept of ''hero'' may include ''good guy'' or ''wikt:white hat, white hat''. In Classics, classical literature, the hero is the main or revered character in Epic poetry, heroic epic poetry celebrated through ancient legends of a people, often striving for milit ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have taken ...

Paleontologist
Paleontology (), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuvier's work on comparative anatomy, and developed rapidly in the 19th century. The term itself originates from Greek (, "old, ancient"), (, ( gen. ), "being, creature"), and (, "speech, thought, study"). Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry, mathematics, and engineering. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hermann Von Meyer
Christian Erich Hermann von Meyer (3 September 1801 – 2 April 1869), known as Hermann von Meyer, was a German palaeontologist. He was awarded the 1858 Wollaston medal by the Geological Society of London. Life He was born at Frankfurt am Main. In 1832, Meyer issued a work entitled ''Palaeologica'', and in course of time he published a series of memoirs on various fossil organic remains: molluscs, crustaceans, fishes and higher vertebrata, including the Triassic predator ''Teratosaurus'', the earliest bird ''Archaeopteryx lithographica'' (1861), the pterosaur ''Rhamphorhynchus'', and the prosauropod dinosaur ''Plateosaurus''. In ''Palaeologica'', Meyer proposed a classification of fossil reptiles into four major groups based on their limbs: *Saurians with Toes Similar to those of Living Species (e.g.'' Teleosaurus'', ''Protorosaurus'', '' Streptospondylus'') *Saurians with Limbs Similar to Heavy Land Mammals (''Iguanodon'', ''Megalosaurus'') *Saurians with Limbs for Swimm ...

Trieste
Trieste ( , ; sl, Trst ; german: Triest ) is a city and seaport in northeastern Italy. It is the capital city, and largest city, of the autonomous region of Friuli Venezia Giulia, one of two autonomous regions which are not subdivided into provinces. Trieste is located at the head of the Gulf of Trieste, on a narrow strip of Italian territory lying between the Adriatic Sea and Slovenia; Slovenia lies approximately east and southeast of the city, while Croatia is about to the south of the city. The city has a long coastline and is surrounded by grassland, forest, and karstic areas. The city has a subtropical climate, unusual in relation to its relatively high latitude, due to marine breezes. In 2022, it had a population of about 204,302. Capital of the autonomous region of Friuli Venezia Giulia and previously capital of the Province of Trieste, until its abolition on 1 October 2017.

Podestà
Podestà (, English: Potestate, Podesta) was the name given to the holder of the highest civil office in the government of the cities of Central and Northern Italy during the Late Middle Ages. Sometimes, it meant the chief magistrate of a city state, the counterpart to similar positions in other cities that went by other names, e.g. ''rettori'' ("rectors"). In the following centuries up to 1918, the term was used to designate the head of the municipal administration, particularly in the Italian-speaking territories of the Austrian Empire. The title was taken up again during the Fascist regime with the same meaning. The podestà's office, its duration and the residence and the local jurisdiction were called ''podesteria'', especially during the Middle Ages, and in later centuries, more rarely during the fascist regime. Currently, ''podestà'' is the title of mayors in Italian-speaking municipalities of Graubünden in Switzerland, but is not the case for the rest of the C ...

Mutius Von Tommasini
Muzio Giuseppe Spirito de Tommasini, sometimes referred to as Muzio Tommasini or as Mutius von Tommasini (4 June 1794 – 31 December 1879) was a botanist and politician born in Trieste under Austria-Hungary. He first became interested in botany as a grammar school student in Ljubljana. While studying medicine at the University of Vienna, he was inspired by the work of professor Joseph Franz von Jacquin (1766-1839), and conducted investigations of flora in the vicinity of Vienna. Afterwards, Tommasini studied law at the University of Graz. A career politician, he received his first appointment in 1817 as an official in the district of Istria. During the following year he was elected district secretary of the city of Split. From 1839 to 1860 he was mayor of Trieste. Following his retirement in 1860, he devoted his time to investigations of local flora. As a botanist he participated in several noteworthy expeditions. Early in his career he took exploratory trips to the Bioko ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
