-Andy- Posted May 4, 2019 Share Posted May 4, 2019 One of my favorite fossil types. Dinosaur eggs come in all shapes and sizes — from an oval as small as a thumb, to a sphere as big as a basketball. These fossils are often faked by the hundreds, if not thousands, in Chinese factories (China is also the world's richest source of true dinosaur eggs). However, there are also many natural-occurring objects mistaken as dinosaur eggs such as concretions or even fortuitously-shaped rocks. Despite these hurdles, dinosaur eggs remain one of the most desirable of all fossils. NOTE: Dinosaur egg and eggshells, by their nature as an ichnofossil, are challenging for private collectors to identify. None of the IDs I provide here are acceptable on a scientific level as I lack the tools to examine the cross section slices of my eggshells. However, for the sake of documentation I will still provide accurate names and locality here to the best of my ability. First up are my Oviraptorid eggs "Common" Name: Oviraptor egg Elongatoolithus sp. 71 - 66 mya | late Cretaceous Nanxiong Basin, Guangdong "Common" Name: Citipati egg Macroolithus yaotunensis 71 - 66 mya | late Cretaceous Nanxiong Basin, Guangdong Length: 8.78 inches (Note: Has composited eggshells) "Common" Name: Oviraptorid(small type) Nest Elongatoolithus sp. 71 - 66 mya | late Cretaceous Nanxiong Formation Guangdong 10 Looking forward to meeting my fellow Singaporean collectors!

snolly50 Posted May 5, 2019 Share Posted May 5, 2019 I enjoyed seeing those eggs, thanks. Human beings, who are almost unique in having the ability to learn from the experience of others, also are remarkable for their apparent disinclination to do so. - Douglas Adams, Last Chance to See Link to comment Share on other sites More sharing options...

HamptonsDoc Posted May 5, 2019 Share Posted May 5, 2019 Eggcellent collection! I've been looking for a Troodon egg for 3 years and still haven't found one. I love when they're embedded in their matrix still and standing straight up. Nice to see some pictures of real eggs posted on the forum! Link to comment Share on other sites More sharing options...
