报告摘要：
Although not as iconic as fossil bones, fossil eggs are valuable source of paleobiological data. That is because they are easily fossilized so there are relatively abundant materials in the fossil record. East Asia has spatiotemporally diverse fossil localities, providing good research opportunities to study reproductive paleobiology of amniotic vertebrates. Although complete egg clutches or eggs are comparatively rare, eggshell fragments are common in Cretaceous deposits in East Asia, so diverse approaches are used to study fossil eggshells. In this seminar, I will introduce the diverse methodologies to study fossil eggshells and a few representative studies that show how these methodologies were used to get paleobiological understandings. Paleontology is an intersection between the biology and geology, so philosophy and techniques of both fields are worth importing to paleontology. Fossil egg research is not an exception, so when more interdisciplinary approaches become available, more unexplored findings will shed light on the history of reproduction of vertebrates.
