Pantolambda
''Pantolambda'' (Greek: "all" (pantos), "lambda" (lambda), in a reference to the shape of upper premolars, similar to the Greek letter lambda) is an extinct genus of Paleocene pantodont mammal. ''Pantolambda'' lived during the middle Paleocene, and has been found both in Asia and North America. Cretaceous mammals, which had to compete with dinosaurs, were generally small insect eaters. ''Pantolambda'' was one of the first mammals to expand into the large-animal niches left vacant by the extinction of the dinosaurs. ''Pantolambda'' and other early pantodonts would quickly evolve into heavy animals such as ''Barylambda'' and '' Coryphodon''. These were the first large browsers, pioneering styles of life later followed by many unrelated groups of mammals: rhinos, tapirs, hippos, ground sloths, and elephants. Pantodonts such as ''Pantolambda'' were definitely not tree dwellers. Description ''Pantolambda'' was large for a Paleocene mammal, about the size of a sheep. A generalized ea ...

Pantodonta
Pantodonta is an extinct suborder (or, according to some, an order) of eutherian mammals. These herbivorous mammals were one of the first groups of large mammals to evolve (around 66 million years ago) after the end of the Cretaceous. The last pantodonts died out at the end of the Eocene (around 34 million years ago). Pantodonta include some of the largest mammals of their time, but were a diversified group, with some primitive members weighing less than and the largest more than . The earliest and most primitive pantodonts, ''Bemalambda'' (with a skull probably the size of a dog) and '' Hypsilolambda'', appear in the early Paleocene Shanghuan Formation in China. All more derived families are collectively classified as Eupantodonta. The pantodonts appear in North America in the middle Paleocene, where ''Coryphodon'' survived into the middle Eocene. Pantodont teeth have been found in South America (''Alcidedorbignya'') and Antarctica, and footprints in a coal mine on Svalb ...

Barylambda
''Barylambda'' (Greek: "heavy" (baros), "lambda" (lambda) in a reference to larger size than that of '' Pantolambda'') is an extinct genus of pantodont mammal from the middle to late Paleocene, well known from several finds in the Wasatchian ( NALMA classification) DeBeque Formation of Colorado and the Clarkforkian Wasatch Formation to Tiffanian Fort Union Formation in Wyoming. Three species of ''Barylambda'' are currently recognized. The creature likely lived a life similar to that of a modern tapir, browsing on foliage and soft vegetation. ''Barylambda'' seems to have been quite successful for an early pantodont, though eventually it seems to have been replaced in its ecosystem by other pantodonts, such as ''Coryphodon''. Description In life, ''Barylambda'' probably resembled a large ground sloth, with a small head and long, well-developed tail and bear-like legs. The length was about with a weight around , about the size of a pony. ''Barylambda'' was large even for a pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.

Its south border abuts the north line of Colorado. History Carbon County was organized in 1868, one of the five original counties in Dakota Territory. Originally about near the center of Wyoming, Carbon County was once part of the Spanish Empire, then part of the Republic of Texas (1835-1845) and part of the State of Texas until 1852 when the northernmost part of that state's claims were ceded to the US government. This area is defined by the 42nd parallel on the north, and straight lines south from there to the headwaters of the Arkansas river on the east and the headwaters of the Rio Grande on the west. The documents defining that area include the Adams-Onís Treaty of 1819, the 1824 Constitution of Mexico, and the 184"Joint Resolution for the Admission of the State of Texas into the Un ...

Natural History Of San Juan County, New Mexico
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant " birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word '' physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-So ...
