The formation of fossil eggs begins with the original egg itself. Not all eggs that end up fossilizing experience the death of their embryo beforehand. Even eggs that successfully hatch can fossilize. In fact, not only is this possible it's actually common. Many fossil dinosaur eggs are preserved with their tops broken open by the escaping ...
Egg fossils are the fossilized remains of eggs laid by ancient animals. As evidence of the physiological processes of an animal, egg fossils are considered a type of trace fossil . Under rare circumstances a fossil egg may preserve the remains of the once- developing embryo inside, in which case it also contains body fossils .

Although the skeletons of dinosaurs can be reconstructed, only their fossilized footprints can determine exactly how they stood and walked. Such tracks ...

The seven footprints, found amidst a clutter of hundreds of prehistoric animal prints, are estimated to be 115,000 years old. Many fossil and artifact windfalls have come from situations like this ...
Two species of ancient human relatives crossed paths 1.5 million years ago. Fossilized footprints in Kenya captured the moment, according to a new study.
Fossilized eggs are widely distributed and are in well preserved conditions. Additionally, the footprints of two webbed-feet/birds are also some of the oldest of its kind to be discovered. The Haenam -gun site is most famous for the footprints of giant dinosaurs discovered there.
The discovery of fossilized footprints made in what’s now New Mexico was a bombshell moment for archaeology, seemingly rewriting a chapter of the human story. New research is offering further ...
