The fossilized remains of a dinosaur about the size of a pigeon that may be the ancestor of birds has been discovered by archeologists in China. Scientists recovered 90 percent of the skeleton which was preserved in rock found in Ningcheng county in Inner Mongolia of northern China. The find was reported in an article in Nature. It has four limbs which lacked contour feathers that could be used for flight, making it a flightless creature. It probably live 176 to 146 million years ago in...

The latest breakthrough in a 120 year-old debate on the evolution of the bird wing was published in the open-access journal PLoS ONE, October 3, by Alexander Vargas and colleagues at Yale University, the University of Wisconsin-Madison and Yale Peabody Museum of Natural History. Bird wings only have three fingers, having evolved from remote ancestors that, like humans and most reptiles, had five fingers. Biologists have typically used embryology to identify the evolutionary origin (homology)...

Regarding Elliott Epstein's June 8 column, "No evolution in this debate," I believe the religion that conflicts with science is evolution. In true science, a theory is proposed to explain available evidence. Rigorous testing will expose bad theory. Evolution has been discredited but lives on in spite of contradicting evidence and its violation of fundamental principles of science. "Widely accepted" means nothing - it was once widely accepted that the sun revolved around the Earth. The...

WASHINGTON (Reuters) - An especially well-preserved specimen of Archaeopteryx shows the first known bird had feet like a dinosaur -- made not for perching but for running on the ground, scientists said on Thursday. The first toe on the fossil turns inward, similar to a human thumb and most like the hunting dinosaurs known as deinonychosaurs -- notably the Velociraptor with its long claw for disemboweling prey. Gerald Mayr of the Forschungsinstitut Senckenberg in Frankfurt, Germany,...

WASHINGTON -- A new analysis of Archaeopteryx, the earliest known birdlike animal, shows it had feet like dinosaurs - a finding that adds weight to the belief that the birds frequenting backyard feeders today are descendants of mighty ancient carnivores. While not all scientists agree, many consider Archaeopteryx the first bird, since it had wings and was the first fossil found with feathers. Details have been lacking on the animals, however, since only a few fossil specimens have been...

penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
