Anomodon Snyderi
''Anomodon'' is an extinct genus of talpid mole from Galena, Illinois. The type, and only species, ''A. snyderi'', was named and described in 1848 by John Lawrence LeConte John Lawrence LeConte (May 13, 1825 – November 15, 1883) was an American entomologist of the 19th century, responsible for naming and describing approximately half of the insect taxa known in the United States during his lifetime,

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ...

Talpidae
The family Talpidae () includes the moles (some of whom are called shrew moles and desmans) who are small insectivorous mammals of the order Eulipotyphla. Talpids are all digging animals to various degrees: moles are completely subterranean animals; shrew moles and shrew-like moles somewhat less so; and desmans, while basically aquatic, excavate dry sleeping chambers; whilst the quite unique star-nosed mole is equally adept in the water and underground. Talpids are found across the Northern Hemisphere of Eurasia and North America (although none are found in Ireland nor in the Americas south of northern Mexico), and range as far south as the montane regions of tropical Southeast Asia. The first talpids evolved from shrew-like animals which adapted to digging late in the Eocene in Europe. '' Eotalpa anglica'' is the oldest known mole, it was discovered in the Late Eocene deposits of Hampshire Basin, UK. The most primitive living talpids are believed to be the shrew-like moles, ...

Mole (animal)
Moles are small mammals adapted to a subterranean lifestyle. They have cylindrical bodies, velvety fur, very small, inconspicuous eyes and ears, reduced hindlimbs, and short, powerful forelimbs with large paws adapted for digging. The word “mole” refers to any species in the family Talpidae, which means “mole” in Latin. Moles are found in most parts of North America, Europe and Asia. Moles may be viewed as pests to gardeners, but they provide positive contributions to soil, gardens, and ecosystem, including soil aeration, feeding on slugs and small creatures that eat plant roots, and providing prey for other wildlife. They eat earthworms and other small invertebrates in the soil. Terminology In Middle English, moles were known as ''moldwarp''. The expression "don't make a mountain out of a molehill" (which means "exaggerating problems") was first recorded in Tudor times. By the era of Early Modern English, the mole was also known in English as ''mouldywarp'', a wor ...

Galena, Illinois
Galena is the largest city in and the county seat of Jo Daviess County, Illinois, with a population of 3,308 at the 2020 census. A section of the city is listed on the National Register of Historic Places as the Galena Historic District. The city is named for the mineral galena, which was in the ore that formed the basis for the region's early lead mining economy. Native Americans, primarily Mesquakie, Ho-Chunk, Sauk, and Menominee had mined galena in the area for more than a thousand years before European Americans settled in the area. Owing to these deposits, Galena was the site of the first major mineral rush in the United States. By 1828, the population was estimated at 10,000, rivaling the population of Chicago at the time. Galena developed as the largest steamboat hub on the Mississippi River north of St. Louis, Missouri. Galena was the home of Ulysses S. Grant and eight other Civil War generals. Today, the city is a tourist destination known for its history, architectu ...

Oliver Perry Hay
Oliver Perry Hay (May 22, 1846 – November 2, 1930) was an American herpetologist, ichthyologist, and paleontologist. Hay was born in Jefferson County, Indiana, to Robert and Margaret Hay. In 1870, Hay graduated with a bachelor of arts from Eureka College in Illinois. He taught at the college as a sciences professor from 1870–1873. He married Mary E. Howsmon of Eureka, Illinois, in 1870. He was a professor at Oskaloosa College in Iowa from 1874–1876. He was a student at Yale University from 1876–1877. Seventeen years after earning his bachelors, he earned his PhD from Indiana University in Bloomington, Indiana. From 1877–1879, he taught at Abingdon College just before it was incorporated into his alma mater, Eureka College. His longest professorship was at Butler University from 1879–1892. From 1894 to 1895, he worked at the Field Museum of Natural History as assistant curator of zoology, where despite his specialty in ichthyology, he worked in all nonornithological f ...

Fossil Taxa Described In 1848
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolut ...

Pleistocene Mammals Of North America
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...
