Q:Information: - In the geologic timescale, the Middle Triassic is the second of three epochs of the Triassic period or the middle of three series in which the Triassic system is divided. It spans the time between Ma and Ma (million years ago). The Middle Triassic is divided into the Anisian and Ladinian ages or stages. - The Carnian (less commonly, Karnian) is the lowermost stage of the Upper Triassic series (or earliest age of the Late Triassic epoch). It lasted from 237 to 228.4 million years ago (Ma). The Carnian is preceded by the Ladinian and is followed by the Norian. Its boundaries are not characterized by major extinctions or biotic turnovers, but a climatic event (known as the Carnian Pluvial Event) occurred during the Carnian and seems to be associated with important extinctions or biotic radiations. - In the geologic timescale, the Anisian is the lower stage or earliest age of the Middle Triassic series or epoch and lasted from million years ago until million years ago. The Anisian age succeeds the Olenekian age (part of the Lower Triassic epoch) and precedes the Ladinian age. - Placodonts ("Tablet teeth") is an extinct order of marine reptiles that lived during the Triassic period, becoming extinct at the end of the period. It is believed that they were part of Sauropterygia, the group that includes plesiosaurs. Placodonts were generally between in length, with some of the largest measuring long. - Paraplacodus was a Placodont from the middle Triassic period , during the Anisian to Ladinian stages . The fossils were uncovered in Northern Italy and the species was named in 1931 by Bernhard Peyer . Paraplacodus means '' Almost Placodus '' , and thus far only one species , P. broilli , has been identified ; as the name suggests , it was similar to Placodus , and also bore a strong resemblance to Saurosphargis . Like all known Placodonts , Paraplacodus was an aquatic reptile that fed almost exclusively on shellfish . Most known Placodont species can be divided into two groups - the unarmored placodontoids , which would resemble a large , scaly , tooth - filled newt , or the armored cyamodontids , which would resemble a heavily armored turtle ; Paraplacodus belonged to the former family . It grew to a length of 1.5 meters ( 4.9 feet ) . The jaws of Paraplacodus were adapted to eat shellfish , with three pairs of protruding teeth in the top row and two rows of protruding teeth in the front of the jaw , with rounded crushing teeth in the upper and lower jaws . Thick ribs formed a box - like ribcage with an almost - square cross-section , which enabled Paraplacodus to remain close to the seabed while hunting for food . - Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of and has a largely temperate seasonal climate and Mediterranean climate; due to its shape, it is often referred to in Italy as "lo Stivale" (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state. - The Ladinian is a stage and age in the Middle Triassic series or epoch. It spans the time between Ma and ~235 Ma (million years ago). The Ladinian was preceded by the Anisian and succeeded by the Carnian (part of the Upper or Late Triassic). - The Triassic is a geologic period and system which spans 50.9 million years from the end of the Permian Period million years ago (Mya), to the beginning of the Jurassic Period Mya. The Triassic is the first period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic was named in 1834 by Friedrich von Alberti, after the three distinct rock layers ("tri" meaning "three") that are found throughout Germany and northwestern Europered beds, capped by marine limestone, followed by a series of terrestrial mud- and sandstonescalled the "Trias". - A mediterranean climate or dry summer climate is the climate typical of the lands in the Mediterranean Basin. The lands around the Mediterranean Sea form the largest area where this climate type is found, but it also is found in most of coastal California, in parts of Western and South Australia, in southwestern South Africa, sections of Central Asia, and in central Chile. - Reptiles are tetrapod (four-limbed vertebrate) animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. - A parliamentary republic is a republic that operates under a parliamentary system of government where the executive branch (the government) derives its legitimacy from and is accountable to the legislature (the parliament). There are a number of variations of parliamentary republics. Most have a clear differentiation between the head of government and the head of state, with the head of government holding real power, much like constitutional monarchies. Some have combined the roles of head of state and head of government, much like presidential systems, but with a dependency upon parliamentary power. - A boot is a type of footwear and a specific type of shoe. Most boots mainly cover the foot and the ankle, while some also cover some part of the lower calf. Some boots extend up the leg, sometimes as far as the knee or even the hip. Most boots have a heel that is clearly distinguishable from the rest of the sole, even if the two are made of one piece. Traditionally made of leather or rubber, modern boots are made from a variety of materials. Boots are worn both for their functionality protecting the foot and leg from water, extreme cold, mud or hazards (e.g., work boots may protect wearers from chemicals or use a steel toe) or providing additional ankle support for strenuous activities with added traction requirements (e.g., hiking) and for reasons of style and fashion. - In the geologic timescale, the Olenekian is an age in the Early Triassic epoch or a stage in the Lower Triassic series. It spans the time between Ma and Ma (million years ago). The Olenekian follows the Induan and is followed by the Anisian. - Placodus (meaning 'flat tooth') was a genus of marine reptiles, belonging to the order Placodontia, which swam in the shallow seas of the middle Triassic period (c. 240 million years ago). Fossils of "Placodus" have been found in Central Europe (Germany, France, Poland) and China. 'paraplacodus' is related to which object entity through the relation of 'taxon rank'?
