Fake or Real Oviraptor egg and two different Hadrosaur Eggs?

[Guest]

Good night All,

 

please try to check attached egg photos. There are 2 hadrosaur eggs and one oviraptor egg. 

Do you thing all this material is fake.

Some person is trying to sell it to me.

Do you thing all this have red flags?

 

Best regards.

Alvaro.

For me, there's too little texture on any of the eggs for them to be real. Moreover, the first hadrosaur egg seems too perfectly round and undamaged to be authentic, whereas the second hadrosaur egg appears to have a sandy texture, rather than that of eggshell. The oviraptorid egg does have some authentic eggshell pieces on certain parts, but also has significant restore (brown part on one of the ends of the egg). As to the blue parts of this egg: I'm not quite sure whether that's damage or restoration (possibly with odd bits of eggshell).

 

Conclusion: I'd pass this by.

 

Then again, I'm not an expert on dinosaur eggs, so lets see what others have to say.

From what I can see from the photos, it seems that these are unprepped, covered with a thin layer of mineral deposit. I feel this may account for the lack of obvious shell texture. Of course in hand with some trial scraping and magnification, would be best to evaluate.

These eggs look like those from Henan Province of China.

The first hadrosaur egg worries me. Just doesn’t look right, possibly a composite. The raptor eggs look authentic but terrible quality and the second is missing most of its shell. The second hadrosaur egg looks ok.

All 3 are real

 

Hadrosaurus egg 1 is problematic however. It seems there might be some composition so I'd avoid it.

 

Oviraptor is either poorly prepped or it too has some composition. It's missing a lot of eggshells

 

Hadrosaurus egg 2 is okay. I'd get this one

Thank you all. I have two very important questions:
Can you inform us between what sizes have an authentic oviraptor egg? 
What weights have an authentic oviraptor egg without matrix?

[Troodon]

Elongatoolithus type eggs that have been attributed to Oviraptorids are about 17 cm long.  However taphonomic processes can affect its length..  Weight is really not a revalent characteristic and a function of its preservation. Locality, shape, size, shell ornamentation and thickness are the most important characteristics to identify eggs to an oogenus

What do you thing about this egg? It is real? It is 15,5 cm long, this is 1,5 cm less than 17 cm.
