Mark A. Klingler/CMNHOldest fossil primate from North America discovered in Mississippi

The 55.8 million year–old fossils, excavated at a site near Meridian, Mississippi, are from a previously unknown species of extinct primate named Teilhardina magnoliana. Because different species of Teilhardina once inhabited all three northern continents at roughly the same time, it has been difficult to reconstruct how these tiny primates dispersed over much of the globe at a time when global climate was changing rapidly while sea levels were also fluctuating. The discovery sheds new light on how the earliest primates migrated to North America during a major global warming event 55.8 million years ago. Click here for the CMNH Press Release.

Mark A. Klingler/CMNHNew family of mammal really a living fossil

Laonastes aenigmamus, a rodent first described in 2005, made international headlines as the sole member of a new family of mammals. But according to a paper published by a team of international researchers led by Carnegie Museum of Natural History paleontologist Mary Dawson, the animal is actually a surviving member of the rodent family Diatomyidae, thought to be extinct for 11 million years.

Mark A. Klingler/CMNHNew Fossil of the Earliest Swimming Mammal Discovered

CMNH scientists Zhe-Xi Luo and Alan Tabrum were on the research team that discovered a brand new species of swimming mammal, Castorocauda lutrasimilis, from the Jurassic lakebeds of China. The description appears in the February 24, 2006 issue of Science, with cover art (at right) by CMNH Scientific Illustrator Mark A. Klingler. Click here for the CMNH Press Release.

spacer line The Hunt for the Dawn Monkey:
Unearthing the Origins of Monkeys, Apes, and Humans

Written by Chris Beard
Illustrated by Mark A. Klingler

Taking us back roughly 45 million years, CMNH Vertebrate Paleontologist Chris Beard offers a tantalizing new perspective on our deepest evolutionary roots. In a fast-paced narrative full of vivid stories from the field, he reconstructs our extended family tree, back to the first anthropoids—the diverse and successful group that includes monkeys, apes, and humans.

The only book written for a wide audience that explores a remote phase of our own evolutionary history, The Hunt for the Dawn Monkey adds a fascinating new chapter to our understanding of humanity's relationship to the rest of life on earth. Illustrated by award-winning CMNH Scientific Illustrator Mark A. Klingler. Click here for publication and ordering information.

spacer spacer PaleoLab
After two years, the preparators in PaleoLab have finished their work on a spectacular skull of Tyrannosaurus rex, nicknamed “Samson” in recognition of the beast’s reputation as the strongest dinosaur of the late Cretaceous. This 65-million-year-old skull is a remarkable find – it appears to be both complete and undistorted. Click here for a recap of the project in the Preparator's Logs.

PopeyeEarliest Mammal
CMNH scientists Zhe-Xi Luo and John Wible have discovered a brand new species of early mammal, dubbed "Popeye" because of its massive forearms. It shows some very unique features that would be otherwise known only in armadillos, but it is older than the armadillo lineage by 100 million years and unrelated to them. Click here for the CMNH Press Release and more images.

SinodelphysSinodelphys: New Fossil of a Primitive Marsupial Discovered
CMNH scientists Zhe-Xi Luo and John Wible are members of a collaborative team of Chinese and American scientists who discovered Sinodelphys szalayi, a 125-million-year-old fossil animal that is the most primitive and oldest known relative of all marsupial mammals. Click here for more information.

Eomaia: The World's Earliest Known Placental Mammal
This nearly complete skeleton was discovered by an international team of scientists – including Carnegie Museum of Natural History’s Zhe-Xi Luo and John Wible – in the famed feathered dinosaur quarry of China’s Liaoning Province.The discovery of this little creature is of big importance to the understanding of the evolution of mammals. Since most mammals living today are placental, all may point to Eomaia scansoria as an ancient ancestor. Click here for more information.

Jeholodens: Unearthing the Roots of the Family Tree
Because very few skeletons of early mammals have been found, scientists have had only vague ideas about their lifestyles. The completeness of the Jeholodens jenkinsi skeleton, however, has allowed CMNH Vertebrate Paleontologist Zhe-Xi Luo and his collaborators to reconstruct some of the complexities of mammalian evolution.

The Bromacker: A Treasure Trove of Specimens
Since 1993, Carnegie Museum of Natural History paleontologists Dr. David Berman and Amy Henrici have been excavating an abandoned sandstone quarry in Germany. The Bromacker Quarry excavations have yielded fascinating specimens that provide new information about the dominant life forms nearly 80 million years before the Age of Dinosaurs. Click here for more information.

Eosimias: Tracking Our Extended Family
Two exciting fossil discoveries offer clues to the origin and evolution of higher primates—the group that today includes monkeys, apes, and humans. A team of American and Chinese paleontologists, organized by Carnegie Museum of Natural History's Dr. Chris Beard, have unearthed fossilized foot bones that provide us with our first glimpse at the skeleton of primates that are near the common ancestry of monkeys, apes, and humans. Click here for more information.

Hadrocodium: A Mammal the Size of a Paper Clip
An international team of researchers led by Carnegie Museum of Natural History Vertebrate Paleontologist Dr. Zhe-Xi Luo has discovered a 195-million-year-old fossil mammal. This find is the smallest known mammal of the Mesozoic and represents a new branch on the mammalian family tree. The newest addition to the mammalian family group also happens to be the tiniest mammal known from the Mesozoic Era, and one of the smallest mammals ever. Click here for more information.
