Stegobium
The drugstore beetle (''Stegobium paniceum''), also known as the bread beetle, biscuit beetle, and misnamed as the biscuit weevil (despite not being a true weevil), is a tiny, brown beetle that can be found infesting a wide variety of dried plant products, where it is among the most common non-weevils to be found. It is the only living member of the genus ''Stegobium''. It belongs to the family Ptinidae, which also includes the deathwatch beetle and furniture beetle. The drugstore beetle has a worldwide distribution though it is more common in warmer climates. It is similar in appearance to the cigarette beetle (''Lasioderma serricorne''), but is slightly larger (adults can be up to 3.5 mm in length). Additionally, drugstore beetles have antennae ending in 3-segmented clubs, while cigarette beetles have serrated antennae (notched like teeth of a saw). The drugstore beetle also has grooves running longitudinally along the elytra, whereas the cigarette beetle is smooth. L ...

Lasioderma Serricorne
''Lasioderma serricorne'', commonly known as the cigarette beetle, cigar beetle, or tobacco beetle, is an insect very similar in appearance to the drugstore beetle (''Stegobium paniceum'') and the common furniture beetle (''Anobium punctatum''). All three species belong to the family Ptinidae. ''L. serricorne'' is around 2–3 mm long, and brown in colour. The beetles, which can fly, live 2–6 weeks and do not feed as adults. They can be distinguished from ''A. punctatum'' by the fact that ''A. punctatum'' has a thorax with a pronounced "humped" shape. ''S. paniceum'' and ''L. serricorne'' have thoraces which have a much less obtuse looking angle when viewed from the side compared to ''A. punctatum'', and thus could be difficult to tell apart. However ''S. paniceum'' has a distinct three-segmented "club" at the end of each antenna whereas ''L. serricorne'' has uniformly serrated antennae of 11 segments. ''L. serricorne'' also has much weaker punctures on the surface of the wi ...

Weevil
Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small, less than in length, and herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae (the true weevils). It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil (''Stegobium paniceum''), which belongs to the family Ptinidae. Many weevils are considered pests because of their ability to damage and kill crops. The grain or wheat weevil (''Sitophilus granarius'') damages stored grain, as does the maize weevil (''Sitophilus zeamais'') among others. The boll weevil (''Anthonomus grandis'') attacks cotton crops; it lays its eggs inside cotton bolls and the larvae eat their way ou ...

Ptinidae
Ptinidae is a family of beetles in the superfamily Bostrichoidea. There are at least 220 genera and 2,200 described species in Ptinidae worldwide. The family includes spider beetles and deathwatch beetles. The Ptinidae family species are hard to identify because they are so small, and they have a compact body structure. They also have similar morphologies within the genera and species of the family. There are three main groups in the superfamily Bostrichoidea: Bostrichidae, Anobiidae, and Ptinidae. These have undergone frequent changes in hierarchical classification since their inception. They have been treated as a single family, three independent families, the two families Bostrichidae and Anobiidae, or the two families Bostrichidae and Ptinidae. More recent literature treats these as the two families Bostrichidae and Ptinidae, with Anobiidae a subfamily of Ptinidae ( Anobiinae). Spider beetles are so named because they look like spiders. Some species have long legs, anten ...

New Jersey Amber
New Jersey Amber, sometimes called Raritan amber, is amber found in the Raritan and Magothy Formations of the Central Atlantic (Eastern) coast of the United States. It is dated to the Late Cretaceous, Turonian age, based on pollen analysis of the host formations. It has been known since the 19th century, with several of the old clay-pit sites now producing many specimens for study. It has yielded a number of organism fossils, including fungi, plants, tardigrades, insects and feathers. The first identified Cretaceous age ant was described from a fossil found in New Jersey in 1966. Occurrence Though named after New Jersey, the fossil-bearing strata of the Raritan and overlying Magothy formations are also exposed in several neighboring U.S. states, including Maryland through south and central New Jersey, across Staten Island and Long Island (coastal areas of New York state), to a northern exposure at Martha's Vineyard, an island of Massachusetts. Of the two formations that New ...

Motschulsky
Victor Ivanovich Motschulsky (sometimes Victor von Motschulsky, russian: link=no, Виктор Иванович Мочульский, 11 April 1810, in St. Petersburg – 5 June 1871, in Simferopol) was a Russian entomologist mainly interested in beetles. Motschulsky was an Imperial Army colonel who undertook extended trips abroad. He studied and described many new beetles from Siberia, Alaska, the United States, Europe, and Asia. While he tended to ignore previous work and his own work on classification was of poor quality, Motschulsky made a massive contribution to entomology, exploring hitherto unworked regions, often in very difficult terrain. He described many new genera and species, a high proportion of which remain valid. Travels Motschulsky's travels included: *1836 - France, Switzerland and the Alps, northern Italy and Austria *1839–1840 - Russian Caucasus, Astrakhan, Kazan and Siberia *1847 - Khirgizia *1850–1851 - Germany, Austria, Egypt, India, France, England, ...

Akrotiri (prehistoric City)
Akrotiri (Greek: Ακρωτήρι, pronounced ) was a Cycladic Bronze Age settlement on the volcanic Greek island of Santorini (Thera). The settlement was destroyed in the Theran eruption sometime in the 16th century BC and buried in volcanic ash, which preserved the remains of fine frescoes and many objects and artworks. Akrotiri has been excavated since 1967 after earlier excavations on Santorini. History The earliest evidence for human habitation of Akrotiri can be traced back as early as the fifth millennium BC, when it was a small fishing and farming village. By the end of the third millennium, this community developed and expanded significantly. One factor for Akrotiri's growth may be the trade relations it established with other cultures in the Aegean, as evidenced in fragments of foreign pottery at the site. Akrotiri's strategic position on the primary sailing route between Cyprus and Minoan Crete also made it an important point for the copper trade, thus allowing it ...

Green River Formation
The Green River Formation is an Eocene geologic formation that records the sedimentation in a group of intermountain lakes in three basins along the present-day Green River in Colorado, Wyoming, and Utah. The sediments are deposited in very fine layers, a dark layer during the growing season and a light-hue inorganic layer in the dry season. Each pair of layers is called a varve and represents one year. The sediments of the Green River Formation present a continuous record of six million years. The mean thickness of a varve here is 0.18 mm, with a minimum thickness of 0.014 mm and maximum of 9.8 mm.Bradley, W. H. The varves and climate of the Green River epoch: U.S. Geol. Survey Prof. Paper 158, pp 87–110, 1929. The sedimentary layers were formed in a large area named for the Green River, a tributary of the Colorado River. The three separate basins lie around the Uinta Mountains (north, east, and south) of northeastern Utah: * an area in northwestern Colorado ea ...

Wyoming
Wyoming () is a state in the Mountain West subregion of the Western United States. It is bordered by Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With a population of 576,851 in the 2020 United States census, Wyoming is the least populous state despite being the 10th largest by area, with the second-lowest population density after Alaska. The state capital and most populous city is Cheyenne, which had an estimated population of 63,957 in 2018. Wyoming's western half is covered mostly by the ranges and rangelands of the Rocky Mountains, while the eastern half of the state is high-elevation prairie called the High Plains. It is drier and windier than the rest of the country, being split between semi-arid and continental climates with greater temperature extremes. Almost half of the land in Wyoming is owned by the federal government, generally protected for public uses. The stat ...

Bronze Age
The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze is harder and more durable than the other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, the higher temperature required for smelting, , in addition to the greater difficulty of working with the metal, placed it out of reach of common use until th ...

Pulses
In medicine, a pulse represents the tactile arterial palpation of the cardiac cycle (heartbeat) by trained fingertips. The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck ( carotid artery), wrist ( radial artery), at the groin ( femoral artery), behind the knee ( popliteal artery), near the ankle joint ( posterior tibial artery), and on foot ( dorsalis pedis artery). Pulse (or the count of arterial pulse per minute) is equivalent to measuring the heart rate. The heart rate can also be measured by listening to the heart beat by auscultation, traditionally using a stethoscope and counting it for a minute. The radial pulse is commonly measured using three fingers. This has a reason: the finger closest to the heart is used to occlude the pulse pressure, the middle finger is used get a crude estimate of the blood pressure, and the finger most distal to the heart (usually the ring finger) is used to nu ...
