Duck-billed dinosaur tooth topography

Grinding Teeth of Duck-bill Dinosaurs More Advanced Than Horses'

Research posts

A new scientific study shows that duck-billed dinosaurs pulverized tough and abrasive plants with grinding teeth more complex than those of cows, horses, and other well-known modern grazers. The researchers, which included Mark Norell, the chair of the Museum’s Division of Paleontology, are the first to recover material properties from fossilized teeth.

Newly Discovered Dinosaur Implies Greater Prevalence of Feathers

News posts

A new species of feathered dinosaur discovered in southern Germany is further changing the perception of how predatory dinosaurs looked. The fossil of Sciurumimus albersdoerferi, which lived about 150 million years ago, provides the first evidence of feathered theropod dinosaurs that are not closely related to birds. The fossil is described in a paper published today in the Proceedings of the National Academy of Sciences by researchers at the Museum and at the Bayerische Staatssammlung für Paläontologie und Geologie and Ludwig Maximilians University, both in Germany.

"Punk Eek," 40 Years Later

Research posts

In the late 1960s, Curator Emeritus Niles Eldredge was a graduate student with a passion for trilobite eyes. He had been taught to expect slow and steady change between the specimens of these Devonian arthropods he collected for his dissertation. Only his trilobites were doing one of two things: staying the same, or evolving in leaps.

New Finding: Dinosaur’s Feathers Were Black with Iridescent Sheen

Research posts

A pigeon-sized, four-winged dinosaur known as Microraptor had black iridescent feathers when it roamed the Earth 130 million years ago, according to new research led by a team of American and Chinese scientists that includes Museum researchers. The dinosaur’s fossilized plumage is the earliest record of iridescent feather color. The findings, which suggest the importance of display in the early evolution of feathers, are published in the March 9 edition of the journal Science.

“This study gives us an unprecedented glimpse at what this animal looked like when it was alive,” said Mark Norell, one of the paper’s authors and chair of the Museum’s Division of Paleontology.

A 19th-Century Gift

From the Collections posts

Not long ago, a descendant of John William Draper, a celebrated 19th-century naturalist, gave the Museum Draper’s collection of fossils from Whitby, England. The set, mostly ammonites, was neatly stowed in a wooden box along with a handwritten list of contents dated 1844 and a price stamp of 28 shillings.

“It’s a lovely cabinet of curiosities,” says Neil Landman, curator in the Division of Paleontology, who suspects Draper bought the collection whole, perhaps as a gift for his children or because it was “the kind of thing any respectable naturalist would have owned.”

Born in England in 1811, Draper emigrated to the U.S. in 1832 and rose to prominence as a chemist, botanist, historian, and pioneering photographer. He served as president of New York University from 1850 to 1873 and was a founder of the NYU Medical School, where he taught chemistry until a year before his death in 1882.
