Grewingkia is a genus of extinct Paleozoic corals, found in Indiana. It contains at least one species, Grewingkia canadensis.
A fossil 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. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of Tiktaalik in the arctic of Canada.
Lontra is a genus of otters from the Americas.
Theriiformes is a clade of mammals. The term was coined by Timothy B. Rowe in his doctoral dissertation, and is defined as the clade formed by the most recent common ancestor of multituberculates and Theria. Mammals more closely related to therians than to multituberculates are included in the clade Trechnotheria. As multituberculates are usually considered more closely related to therians than monotremes are, it is considered to be a subgroup of the mammalian crown group.
Anomalomyidae is a family of extinct muroid rodents from Europe.
The Cypriot mouse is a species of mouse endemic to Cyprus. Its primary habitat seems to be the vineyards and fields of the Troödos Mountains region.
Kromdraai Conservancy is a protected conservation park located to the south-west of Gauteng province in north-east South Africa. It is in the Muldersdrift area not far from Krugersdorp.
The Geological Survey of India (GSI) currently maintains two protected areas bearing rich fossil deposits.
The Lake Macquarie Petrified Forest is a petrified pine tree forest at Fennell Bay, Lake Macquarie, New South Wales, Australia. Geologically it is located in the Permo-Carboniferous strata. The nearest town is Swansea.
Stylemys is the first fossil genus of dry land tortoise belonging to the order Testudines discovered in the United States. The genus lived in temperate to subtropical areas of North America, Europe, and Asia, based on fossil distribution. The genus was first described in 1851 by Joseph Leidy. The tortoise was common in the prehistoric Badlands, especially Nebraska and South Dakota. The species has also been found in the formations in and around Badlands National Park. Fossil fragments have also been found in the Palm Park Formation of New Mexico.
Manchurochelys is an extinct genus of turtle. It existed during the early Cretaceous of what is now northeast China. It has been found in the Jianshangou Bed of West Liaoning's Yixian Formation. However, it is a rarely found fossil.
The Fossil Ridge Wilderness is a U.S. Wilderness Area located approximately 16 miles (26 km) northeast of Gunnison, Colorado in the Gunnison National Forest. The 13,992-acre (56.62 km2) wilderness includes Fossil Ridge, a high, exposed ridge of Paleozoic carbonates that contain epeiric sea fossils. Elevations in the wilderness range from 8,880 feet (2,710 m) at Summerville Creek to 13,254 feet (4,040 m) at the summit of Henry Mountain. Elk, deer, mountain goats, and bighorn sheep can be found in the wilderness.
CI1 fossils refer to alleged morphological evidence of microfossils found in five CI1 carbonaceous chondrite meteorite fall: Alais, Orgueil, Ivuna, Tonk and Revelstoke. The research was published in March 2011 in the fringe Journal of Cosmology by Richard B. Hoover, an engineer. However, NASA distanced itself from Hoover's claim and his lack of expert peer-reviews.
Carbonemys cofrinii is an extinct giant podocnemidid turtle known from the Middle Paleocene Cerrejón Formation of the Cesar-Ranchería Basin in northeastern Colombia. The formation is dated at around 60 to 57 million years ago, starting at about five million years after the KT extinction event.
Paleontology in Kentucky refers to paleontological research occurring within or conducted by people from the U.S. state of Kentucky.
