Hello all, I have a question wrt age of the eggs, and to know which genus and oogenus this might be. Before, here, I had posted a lot of photos and a video but somehow they are mostly gone, so I will repost the video. What I have from the seller Hadrosauridae family, possibly Saurolophus genus Possibly Dendroolithus oogenus 80 mio. year old, Cenomanian, Late Cretaceous Egg size 10.5 to 12cm (4 to 4.5"), about 8-9kg (18lbs) Xixia Basin, Henan province, China Now come the contradictions of the above given data Hadrosauridae: 86–66 Ma (mio. years ago) --> Santonian-Maastrichtian (2) Saurolophus: 70–66 Ma --> Maastrichtian (3) "80 mio. year old" --> Campanian "Cenomanian" <-- 100.5-93.9 Ma Dendroolithus: 99–66 Ma --> complete Late Cretaceous (1,4) Most websites state those kind of eggs are from 80-70 or 84-71 Ma --> Santonian-Maastrichtian (1,5,6,7) On an online auction site, I found 70-65 Ma --> Maastrichtian (8) ScienceDirect states Dendroolithus oogenus from Xixia Basin are 96-83 Ma --> Cenomanian-Santonian (9) Could potentially be from Gaogou Formation, Majiacun Formation, or Sigou Formation (10,11,12) (https://en.wikipedia.org/wiki/Late_Cretaceous) So, all this does not fit together really well, does it? As Hadrosauridae lived during Santonian-Maastrichtian, 86–66 Ma, everything older should be ruled out, correct? Thus, if ScienceDirect is right, we should be within 86-83 Ma, which is Santonian. If so, most websites (5,6,7,8 & of my seller) are wrong, plus, it ain't be Saurolophus. ==} Can anyone explain this?

Hi guys, I found this egg on al local auction website. To me it looks very real, but I would like your opinion on it. It is real a dream for me to poses a real Dinosaur egg. The egg is form a Segnosaurus and is found in the Xixia region in China. Kind regards, JK
