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 ...
The presence of several hundred parasitic eggs suggests the person was riddled with intestinal worms (specifically maw-worms and whipworms [5]). In 1991, Andrew Jones, a York Archaeological Trust employee and palaeoscatologist , made international news with his appraisal of the item for insurance purposes: "This is the most exciting piece of ...

Some embryos have been interpreted as colonies of sulfur-reducing bacteria, a claim that cannot be upheld in all cases. [3]Embryo fossils found in Doushantuo Formation of southern China exhibit occasional asynchronous cell division, common in modern embryos, implying that sophisticated mechanisms for differential cell division timing and embryonic cell lineage differentiation evolved before ...
