Exquisitely preserved embryo found inside fossilized dinosaur egg
A 72- to 66-million-year-old embryo found inside a fossilized dinosaur egg sheds new light on the link between the behavior of modern birds and dinosaurs, according to a new study......»»
Greenland landscape history preserved under ice sheet
Greenland wasn't always covered in ice. In fact, within the last 1.1 million years, Greenland had thriving vegetation and ecosystems......»»
Traces of Earth"s early magma ocean identified in Greenland rocks
New research led by the University of Cambridge has found rare evidence—preserved in the chemistry of ancient rocks from Greenland—which tells of a time when Earth was almost entirely molten......»»
Microscope helps with dinosaur puzzle
Fossil sites sometimes resemble a living room table on which half a dozen different jigsaw puzzles have been dumped: It is often difficult to say which bone belongs to which animal. Together with colleagues from Switzerland, researchers from the Univ.....»»
Fossilized feeding frenzy: 47-million-year-old fly found with a full belly
An international team of scientists with Fridgeir Grímsson from the University of Vienna has found a previously unknown fossil fly species in old lake sediments of the Messel Pit, a UNESCO World Heritage Site in Germany. In the stomach of the fossil.....»»
From egg to embryo: How developing zebrafish keep RNA levels in check
Mature egg cells and early embryos do not generate their own RNA molecules—instead, they rely on stored maternal RNAs to synthesize their proteins. As the embryo develops, some of these RNAs become superfluous and need to be degraded. Researchers a.....»»
Long-accepted theory of vertebrate origin upended by fossilized fish larvae
A new study out of the University of Chicago, the Canadian Museum of Nature and the Albany Museum challenges a long-held hypothesis that the blind, filter-feeding larvae of modern lampreys are a holdover from the distant past, resembling the ancestor.....»»
Fossil forests under Antarctic ice
In around 1833 the first specimens of fossilized wood from Antarctica were reported by surgeon, naturalist and artist James Eights......»»
World"s first dinosaur preserved sitting on nest of eggs with fossilized babies
The fossil in question is that of an oviraptorosaur, a group of bird-like theropod dinosaurs that thrived during the Cretaceous Period, the third and final time period of the Mesozoic Era (commonly known as the 'Age of Dinosaurs') that extended from.....»»
"Pompeii of prehistoric plants" unlocks evolutionary secret: study
Spectacular fossil plants preserved within a volcanic ash fall in China have shed light on an evolutionary race 300 million years ago, which was eventually won by the seed-bearing plants that dominate so much of the Earth today......»»
Oceans were stressed preceding abrupt, prehistoric global warming
Microscopic fossilized shells are helping geologists reconstruct Earth's climate during the Paleocene-Eocene Thermal Maximum (PETM), a period of abrupt global warming and ocean acidification that occurred 56 million years ago. Clues from these ancien.....»»
Team of bioethicists and scientists suggests revisiting 14-day limit on human embryo
An international team of bioethicists and scientists contends it may be justified to go beyond the standing 14-day limit that restricts how long researchers can study human embryos in a dish. Going beyond this policy limit could lead to potential hea.....»»
WOX9: A jack of all trades
Researchers used CRISPR, a genome-editing tool, to figure out the hidden roles of a developmental gene called WOX9. It usually induces flower branching in tomatoes and influences embryo growth in a plant related to broccoli. By tweaking the DNA in th.....»»
High-resolution ocean model provides insight into sea turtles" lost years
An exquisitely detailed global ocean model simulation from the National Center for Atmospheric Research (NCAR) has given scientists rare insight into where baby sea turtles may go in their "lost years" after they scramble off the sandy beaches where.....»»
Asteroid Dust Found in Crater Closes Case of Dinosaur Extinction
Phys.org shares an announcement from the University of Texas at Austin: Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million years ago by.....»»
Argentine titanosaur may be oldest yet: study
A colossal dinosaur dug up in Argentina could be the oldest titanosaur ever found, having roamed what is now Patagonia some 140 million years ago at the beginning of the Cretaceous period, scientists said Sunday......»»
First rebbachisaurid dinosaur remains found in Asia
A pair of researchers with the Russian Academy of Sciences and the National Museum of Natural History in the U.S., respectively, has respectively, uncovered the first known example of a rebbachisaurid dinosaur to be found in Asia. Alexander Averianov.....»»
Asteroid dust found in crater closes case of dinosaur extinction
Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million years ago by finding a key piece of evidence: asteroid dust inside the impact crater.....»»
Using a multipronged approach to investigate the diet of ancient dogs
Coprolites, or fossilized feces, are often used to understand the dietary preferences of ancient civilizations. However, the samples are often contaminated, making the analysis difficult. A new study, published in Scientific Reports, uses different t.....»»
Large privately owned redwood forest is preserved in $24.7 million deal
A vast redwood forest located 80 miles north of San Francisco and sprawling nearly as large as Big Basin Redwoods State Park in the Santa Cruz Mountains has received permanent protection under a deal between a Bay Area environmental group and the pro.....»»
8-Year-Old Calls Out NPR For Lack Of Dinosaur Stories
An 8-year-old from Minneapolis recently pointed out a big problem with NPR's oldest news show, All Things Considered. Leo Shidla wrote to his local NPR station: My name is Leo and I am 8 years old. I listen to All Things Considered in the car with mo.....»»
