Complete and authentic egg, which, based on the formation in which it was found, can be attributed to Hadrosaurus or Therizinosaurus. (Because the eggs of Therizinosaurus and Hadrosaurus were both round and about the same size, it was difficult to tell them apart.) The shell of this egg is still quite intact, it is very beautiful. It has obvious lines. Approximately 11 cm in diameter. This fossil is guaranteed to be authentic.
