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.....»»
The Deep-time Digital Earth program: Data-driven discovery in geosciences
Humans have long explored three big scientific questions: the evolution of the universe, the evolution of Earth, and the evolution of life. Geoscientists have embraced the mission of elucidating the evolution of Earth and life, which are preserved in.....»»

How to hunt fossils responsibly: 5 tips from a professional paleontologist
Many of us, at some point or another, dreamed of hunting for dinosaur fossils when we grew up. Paleontology—the study of natural history through fossils—is the scientific reality of this. It encompasses all ancient lifeforms that left their trace.....»»
Rare fossilized algae, discovered unexpectedly, fill in evolutionary gaps
When geobiology graduate student Katie Maloney trekked into the mountains of Canada's remote Yukon territory, she was hoping to find microscopic fossils of early life. Even with detailed field plans, the odds of finding just the right rocks were low......»»
Advanced mouse embryos grown outside the uterus
To observe how a tiny ball of identical cells on its way to becoming a mammalian embryo first attaches to an awaiting uterine wall and then develops into nervous system, heart, stomach and limbs: This has been a highly-sought grail in the field of em.....»»
Mouse embryos grow for days in culture, but the requirements are a bit nuts

Ancient fish DNA provides a window back in time
The accidental discovery of fossilized three-spine stickleback bones dating back 12 thousand years, has enabled scientist to confirm parallel evolution, or evolutionary changes or adaptions which take place repeatedly......»»
Prehistoric armoured dinosaur may have been able to dig
Newly excavated skeletal remains of an ankylosaurid—a large armored herbivore that lived during the Cretaceous Period—may indicate that members of this family of dinosaurs were able to dig, according to a study published in Scientific Reports. Th.....»»

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.....»»
