Researchers Have Discovered, In Antarctica, A Fossilized Dinosaur Soft-Shelled Egg That They Call “The Thing.” The Thing Is The Largest Soft-Shelled Egg, And The Second Biggest Animal Egg (After Eggs From The Extinct Elephant Bird) Ever Discovered. Researchers Are Of The Opinion That A Giant Marine Reptile, The Mosasaur, Laid The Egg.
