Lee Rannals for redOrbit.com - Your Universe Online Scientists at the National Museum of Natural History in Paris say ancient sloths once spent some of their time in the ocean. Sloths are known as tree dwellers, but the latest research published in the Proceedings of the Royal Society B says that these creatures use to head out into the sea about five to eight million years ago. The team came to this conclusion after analyzing Peruvian sloth fossils belonging to five different...

MELBOURNE, Fla., March 21, 2013 /PRNewswire-USNewswire/ -- A National Science Foundation grant of $405,000 will fund Mark Bush and biological sciences graduate students on summer field research explorations to Brazil, Peru, and Panama over the next three years. Their megafauna extinction research will explore the cause of the largest recent mass extinction of large mammals. The extinction event occurred between 15,000 and 9,000 years ago--a time of rapid warming at the end of the last Ice Age...

CLEVELAND, March 1, 2012 /PRNewswire-USNewswire/ -- Cut marks found on Ice Age bones indicate that humans in Ohio hunted or scavenged animal meat earlier than previously known. Dr. Brian Redmond, curator of archaeology at The Cleveland Museum of Natural History, was lead author on research published in the February 22, 2012 online edition of World Archaeology. Redmond and researchers analyzed 10 animal bones found in 1998 in the collections of the Firelands Historical Society...

Identifying species, separating out closely related species and managing each type on its own, is an important part of any animal management system. Some species, like the two types of two-toed sloth, are so close in appearance and behavior that differentiation can be challenging. Conservation researchers at San Diego Zoo Global's Institute of Conservation Research have developed a mechanism for identifying these reclusive species from each other. "Species identification of two-toed sloths...

Zoologists of the University of Jena find out how sloths perfected energy saving They live their lives upside down; instead of defying the force of gravity in an upright position, sloths spend most of their lives hanging in trees upside down. If they have to move, they do so only slowly. Very slowly. But why are sloths so "˜lazy"˜? And how has the locomotive system of these outsiders adapted to their unhurried lifestyle in the course of evolution? Zoologists of the...

As a rule all mammals have the same number of vertebrae in their necks regardless of whether they are a giraffe, a mouse, or a human. But both sloths and manatees are exceptions to this rule having abnormal numbers of cervical vertebrae. New research published in BioMed Central's open access journal EvoDevo shows how such different species have evolved their unusual necks. Birds, reptiles and amphibians have varying number of vertebrae in their necks, swans have 22-25, but mammals, regardless...

Temperature increases resulting from climate change in the Southwest will likely eliminate Joshua trees from 90 percent of their current range in 60 to 90 years, according to a new study led by U.S. Geological Survey ecologist Ken Cole. The research team used models of future climate, an analysis of the climatic tolerances of the species in its current range, and the fossil record to project the future distribution of Joshua trees. The study concludes that the species could be restricted to...

New research by scientists at the University of Cambridge in England gives insight into how sloths, one of the few mammals with more than seven neck vertebrae, evolved their uniquely long necks. The mystery of how the three-toed sloth came to have as many as 10 neck vertebrae has long puzzled scientists, given that most of the 5,000 mammal species have exactly seven vertebrae in their necks. Other animals, such as birds and lizards, vary greatly in the number of vertebrae in their...

Roughly 15,000 years ago, at the end of the last ice age, North America's vast assemblage of large animals "” including such iconic creatures as mammoths, mastodons, camels, horses, ground sloths and giant beavers "” began their precipitous slide to extinction. And when their populations crashed, emptying a land whose diversity of large animals equaled or surpassed Africa's wildlife-rich Serengeti plains then or now, an entirely novel ecosystem emerged as broadleaved trees once...

Paramyladon
2012-04-23 07:19:17

The Paramyladon, an extinct genus of ground sloth, was native to North America. It lived from the Pliocene era to the Pleistocene era, a period of about 4.889 years. Remains of this creature have been found as far south as Guatemala, throughout North America, and even as far north as Alberta, Canada. Paramyladon has been easily mistaken with another ground sloth called Glossotherium, due to major similarities. Barnum Brown created the Paramyladon genus in 1903 with a species of P....

The Nothrotheriops, a genus of ground sloths from the Pleistocene , resided in South and North America. Although related to the Megatherium , a much larger and more well-known ground sloth, Nothrotheriops was recently placed in the family Nothrotheriidae.  It migrated from South America about one million years ago. The Nothrotheriops has been found as far north as Alberta, Canada, causing it to be one of the most northerly of its kind. However, they primarily lived in the southwest in states...

The species, M. leptostomus, was named in 1893. It lived from Florida to Texas, north to Kansas and Nebraska, and west to New Mexico, Nevada, Oregon, and Washington. Fossils have been discovered in numerous...

Ground sloths are extinct edentate (Superorder Xenarthra) mammals that are believed to be relatives of tree sloths and three-toed sloths. They may have died out as recently as 1550 in Hispaniola and Cuba, but had long since been extinct on the mainland. The four identified species found in the United States consist of Harlan's Ground Sloth (Paramylodon harlani), Jefferson's Ground Sloth (Megalonyx jeffersonii), Laurillard's Ground Sloth (Eremotherium laurillardi), and the Shasta Ground...
