Researchers used brown and black chicken feathers for their study

April Flowers for redOrbit.com - Your Universe Online It has been proposed by paleontologists who study fossilized feathers that the shapes of certain microscopic structures found inside the feathers might tell us the color of the ancient birds. If these structures are melanosomes, that could be true. A new study, led by North Carolina State University, however, demonstrates that it is not yet possible to tell if the structures are melanosomes, or remnants of ancient bacteria. Found...

Revision To Rules To Decipher Color In Dinosaurs Suggests Connection Between Color And Physiology
2014-02-13 12:36:46

University of Texas at Austin New research that revises the rules allowing scientists to decipher color in dinosaurs may also provide a tool for understanding the evolutionary emergence of flight and changes in dinosaur physiology prior to its origin. In a survey comparing the hair, skin, fuzz and feathers of living terrestrial vertebrates and fossil specimens, a research team from The University of Texas at Austin, the University of Akron, the China University of Geosciences and four...

sea monster pigment
2014-01-09 04:50:18

redOrbit Staff & Wire Reports - Your Universe Online Newly discovered fossilized skin pigments from a trio of multi-million-year-old marine reptiles reveal that these real-life sea monsters were at least partially dark colored when they were alive, according to research appearing in the latest edition of the journal Nature. The fact that creatures such as mosasaurs and ichthyosaurs were dark-colored is likely to have contributed to more efficient thermoregulation, while also serving...

Fossil X-Rays Determine Archaeopteryx Had Bright Plumage
2013-06-12 12:51:11

Brett Smith for redOrbit.com - Your Universe Online The ℠dino-bird´ Archaeopteryx has long fascinated paleontologists and a new study in the Journal of Analytical Atomic Spectrometry suggests that the animal had bright plumage and wasn´t all-black as previously thought. Using a series of cutting-edge X-ray experiments, a team led by researchers from the University of Manchester found chemical traces of pigments in a 150 million-year-old fossil of the early bird....

African Starlings Change Color 10 Times Faster Than Their Ancestors
2013-06-11 10:45:12

University of Akron It's not going to happen while you're peering through your binoculars, but African glossy starlings change color more than 10 times faster than their ancestors and even their modern relatives, according to researchers at The University of Akron and Columbia University. And these relatively rapid changes have led to new species of birds with color combinations previously unseen, according to the study funded in part by the National Science Foundation and published today...

Jurassic Squid Ink Very Similar To Modern Squid Ink

An international team of scientists have for the first time discovered two 160-million-year-old giant cephalopod fossils with intact ink sacs that contain dried pigment similar to that of modern cuttlefish. The researchers, of which includes a professor from the University of Virginia, said the ancient brownish-black pigment, known as eumelanin, is widespread in the animal kingdom in squid ink, bird feathers and even human hair and skin. And because the fossilized pigment is so similar to...

Image 1 - Microraptor Had Black, Iridescent Feathers, Scientists Report
2012-03-09 04:58:52

A four-winged, feathered dinosaur that was the size of a pigeon and lived approximately 130 million years ago had black feathers with an iridescent sheen, a team of US and Chinese researchers has revealed. In their study, scientists from the Beijing Museum of Natural History, Peking University, the University of Texas at Austin, the University of Akron, and the American Museum of Natural History (AMNH) analyzed a specimen of the Microraptor, a non-avian dinosaur that in 2003 became the...

New Research Shows Feathered Dinosaur Could Fly
2012-01-25 06:22:05

[ Watch the Video ] An international team of researchers led by Brown University has shed some new light on whether the winged dinosaur Archaeopteryx could fly. The team has determined that a well-preserved feather on the raven-sized dinosaur's wing was black, which is evidence that the feathers had traits that could help Archaeopteryx fly. Also, the researchers determined that the fossilized feather's structure is identical to living birds, according to the research published in the...

Paleontologists have unearthed the fossilized remains of a giant penguin in Peru that lived 36 million years ago.  The discovery is the first extinct penguin ever found with preserved evidence of scales and feathers, the researchers said. The new species, dubbed Inkayacu paracasensis, or Water King, had feathers that were reddish brown and grey, distinct from the black tuxedoed look of modern day penguins.  At nearly five feet tall, the Inkayacu was one of the largest penguins ever...

Deciphering microscopic clues hidden within fossils, scientists have uncovered the vibrant colors that adorned a feathered dinosaur extinct for 150 million years, a Yale University-led research team reports online Feb. 4 in the journal Science. Unlike recently published work from China that inferred the existence of two types of melanin pigments in various species of feathered dinosaurs, the Science study analyzed color-imparting structures called melanosomes from an entire fossil of a single...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
