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 .
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 ...
Fossilized Dinosaur eggs displayed at Indroda Dinosaur and Fossil Park. This timeline of egg fossils research is a chronologically ordered list of important discoveries, controversies of interpretation, taxonomic revisions, and cultural portrayals of egg fossils. Humans have encountered egg fossils for thousands of years. In Stone Age Mongolia, local peoples fashioned fossil dinosaur eggshell ...
Reptile egg fossils are the fossilized remains of eggs laid by reptiles. The fossil record of reptile eggs goes back at least as far as the Early Permian . However, since the earliest reptile eggs probably had soft shells with little preservation potential , reptilian eggs may go back significantly farther than their fossil record.
The most famous pastebin is the eponymous pastebin.com. [citation needed] Other sites with the same functionality have appeared, and several open source pastebin scripts are available. Pastebins may allow commenting where readers can post feedback directly on the page. GitHub Gists are a type of pastebin with version control. [citation needed]
Scientists have revealed fossils of a giant salamanderlike beast with sharp fangs that ruled waters before the first dinosaurs arrived. The predator, which was larger than a person, likely used ...
Fossil evidence supports this general idea since swarms of hatchling ammonitellae fossils are known although there are no associated egg fossils. [2] One of the eggs preserved in the Kimmeridge Clay ammonite egg cluster K1486 bears crystalline phosphate on its surface. Since phosphate is mobile only in organic form this suggests the eggs were ...
Tree remains that have undergone petrifaction, as seen in Petrified Forest National Park. In geology, petrification (from Ancient Greek πέτρα (pétra) 'rock, stone') is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.
