Well-Preserved Embryo Found Inside Fossilized Dinosaur Egg
A rare look inside a fossilized dinosaur egg found in southern China has revealed an exquisitely preserved embryo -- and evidence suggesting that some of these prehistoric creatures had even more in common with modern birds than previously thought. F.....»»
New toothy diving dinosaur discovered
A new species of non-avian dinosaur with a streamlined body similar to those of modern diving birds, such as penguins and auks, is described in a study published in Communications Biology. The findings represent the first case of a non-avian theropod.....»»
T. rex"s fancy footwork owed to special ligaments, study finds
How did Tyrannosaurus rex catch its food? Looking at T. rex's fossilized skull, the answer may seem obvious: monstrous jaws and sharp teeth capable of delivering a multi-ton bite force......»»
Mongolian fossil is first known species of streamlined non-avian theropod dinosaur to walk on two legs
A team of researchers from Seoul National University, the University of Alberta and the Mongolian Academy of Sciences has identified the first known example of a streamlined, non-avian theropod dinosaur to walk on two legs. In their paper published i.....»»
Fossil overturns more than a century of knowledge about the origin of modern birds
Fossilized fragments of a skeleton, hidden within a rock the size of a grapefruit, have helped upend one of the longest-standing assumptions about the origins of modern birds......»»
Oldest Pterodactylus fossil found in Germany
Pterosaurs, the flying reptiles of the dinosaur era, originated in the Late Triassic (227 million years ago) and became extinct at the end-Cretaceous extinction event (66 million years ago). With wing spans ranging from 1 to 12 meters, they dominated.....»»
New dinosaur egg species helps crack mystery of Cretaceous ecosystem in Japan
Giant skeletons aren't the only evidence that dinosaurs left behind. Tiny eggshell fragments can reveal aspects of Mesozoic ecosystems that fossilized bones and teeth fail to capture, especially because the skeletons of smaller animals were less like.....»»
Old tech sounds preserved as part of huge audio project
The Cities and Memory sound project includes a growing collection of recordings of various tech gear from years gone by......»»
Cracking open a fossil bone reveals rapid juvenile growth in early tetrapods
The rise of tetrapods (four-limbed vertebrates) is one of the iconic evolutionary transitions preserved in the fossil record. These animals, which lived about 385 to 320 million years ago during the Devonian and Carboniferous periods of Earth's histo.....»»
GBBN expands historic Pennsylvania residence with metal-clad education facility
US architecture studio GBBN preserved and expanded a 19th-century home in Erie, Pennsylvania into an educational facility with a glass bridge connection and metal-clad, barn-like structure. Read more US architecture studio GBBN preserved a.....»»
Going to "femoral head" of class to explain dinosaur evolution
Dinosaurs—and birds—wouldn't have been able to stand on their own two feet without some radical changes to their upper thigh bones. Now, a new study by Yale paleontologists charts the evolutionary course of these leggy alterations......»»
Scientists "pin the tail" on world-first IVF treatment for donkeys
A University of Queensland-led research group has created the world's first successful donkey embryo using in-vitro fertilization (IVF), which could save dozens of endangered donkey species......»»
Footprints claimed as evidence of ice age humans in North America need better dating, new research claims
The wide expanse of an ancient lakebed in New Mexico holds the preserved footprints of life that roamed millennia ago. Giant sloths and mammoths left their mark, and alongside them, signs of our human ancestors. Research published in September 2021 c.....»»
Prehistoric predator? Artificial intelligence says no
Artificial intelligence has revealed that prehistoric footprints thought to be made by a vicious dinosaur predator were in fact from a timid herbivore......»»
Insects with radical metamorphosis found to have two embryo-like stages
Skoltech researchers have shown genes involved in embryonic development to be at work in pupation—the drastic transformation that butterflies and some other insects undergo as their larvae mature. The discovery furthers our understanding of the pup.....»»
Extinct but newly discovered: Germany"s oldest freshwater shrimp
An international team of researchers led by the Museum für Naturkunde Berlin has described Germany's first fossil freshwater shrimp species in the journal Scientific Reports. Most shrimps love marine habitats, but this 48-million-year-old fossilized.....»»
Student-led dinosaur excavation culminates in airlift
The process of unearthing a dinosaur skeleton from the ground, bit by bit, is complicated yet incredibly rewarding. The ups and downs of the excavation process is something Annie McIntosh and Mark Powers know all about—the two University of Alberta.....»»
500 million year-old fossils reveal answer to evolutionary riddle
An exceptionally well-preserved collection of fossils discovered in eastern Yunnan Province, China, has enabled scientists to solve a centuries-old riddle in the evolution of life on earth, revealing what the first animals to make skeletons looked li.....»»
The immortality of germ cells
Germ cells, the reproductive cells that eventually become eggs and sperm, are set aside early in embryonic development, when the embryo is just a hollow ball of cells called the gastrula. This means that the cells transferring genetic information to.....»»
T-rex in Singapore as experts decry "harmful" auctions
Dinosaur fans got a glimpse of a Tyrannosaurus rex skeleton as it went on display in Singapore Friday before an auction next month, as experts slammed the big-money bone trade as "harmful to science"......»»
Fossil bird"s skull reconstruction reveals a brain made for smelling and eyes made for daylight
Jeholornis was a raven-sized bird that lived 120 million years ago, among the earliest examples of dinosaurs evolving into birds, in what's now China. The fossils that have been found are finely preserved but smashed flat, the result of layers of sed.....»»
