These and other Pleistocene megafauna, or large animals of the Pleistocene epoch, were some of the largest mammals to ever walk the Earth.

Take for example a seemingly monumental find at one of North America’s richest fossil sites, the Dartelle Shell Pit near Ruskin. The rich muck prevented bone deterioration for thousands of years until amateur paleontologists Roger Alexon and Don Serbousek discovered them lying in the bottom of a county borrow pit in Dionisios YoulatosJ. It was vegetarian, feeding on the plentiful plants that flourished here.

The charges aren’t a reflection of an unstable discipline, but rather a healthy sign that scientists are discovering more and more evidence to prove or disprove their theories.

A new extinct primate among the Pleistocene megafauna of Bahia, Brazil. The importance of fossils. It is probably safe to say that all giant ground sloths were imposing, no matter how tall or large they were, as evidenced by their skeletons.


The truth is that private collectors and museums want to have the largest mastodon or the tallest giant ground sloth or the grandest of something or another. World authority Gord Edmund declared the skeleton the best preserved and most complete fossil of its kind in North America.

For a while, it looked as if paleontologists there had unearthed the mother of all giant ground sloths at the west Florida fossil site, a bone bed that had produced millions of Pleistocene period animal bones over the past decade.

The real cranium and the rest of the sloth bones are so compelling that paleontologists and scientists from around the world, including Cartelle, frequent the museum to examine the remains. From This Paper Topics from this paper. The species name-change may not seem like earth-shattering news to us regular folks, but among professional fossil-finders, it has caused quite a stir, as do most changes and challenges to the fossil record. A nearly complete skeleton of a robust-bodied New World monkey that resembles living spider monkeys was recovered from undisturbed Pleistocene deposits in the Brazilian state of Bahia.


The state of preservation of the skeletal remains was the result of conditions at the site from which they were excavated in the late s, a dense deposit of ancient fossils called the Daytona Beach Bone Bed.

Of course, the lack of data has never stopped fossil collectors from exaggerating the magnitude of their finds. On the other hand, big finds are big news, and the embellishment of evidence, in varying doses, will always play a role in the interpretation of a discovery. Although it is difficult to determine the size of an animal from a lone fossil, paleontologists nevertheless suggested that the Leisey sloth once towered above his relations.

The report, published in the prestigious Journal of Vertebrate Paleontology, uses the Daytona example to prove the existence of a single Pan-American species of sloth, and not the three that traditionally have been accepted by experts over the past century. Cadtelle team of scientists led by Dr.

In keeping with this tradition, Volusia County offers its version of the best of the best – the nearly perfect remains of an Eremotherium laurillardi giant ground sloth. Gordon Edmund, world renown giant ground sloth expert, offered that an foot sloth would be an unusually large dartelle, if it turned out to be this large. Better fossils have always meant better press, and some fossil bone hunters are often quick to make claims of grandiose discovery for the sake of exposure.
