A major paleontological discovery has scientists buzzing: fossilized dinosaur eggs estimated to be 100 million years old have been found in the U.S., offering new insights into the prehistoric landscape of North America.
Recovered from a sedimentary rock formation, the eggs show signs of having belonged to herbivorous dinosaurs, possibly hadrosaurs. Their porous shells suggest they were buried in soil nests — much like modern reptiles.
This is one of the oldest and best-preserved egg finds in the region, helping bridge gaps in the fossil record for mid-Cretaceous America.
According to a report published recently, similarities to eggs found in Asia hint at possible ancient migration or continental connection during the Mesozoic era.
Age | Shell type | Likely dinosaur | Fun fact |
---|---|---|---|
100 million years | Porous, oval | Hadrosaur | Nests were communal |
90 million | Thick-shelled | Sauropod | Eggs larger than a watermelon |
80 million | Smooth shell | Oviraptor | Guarded nests like birds |
Interestingly, these eggs may support theories that some dinosaurs traveled between Asia and North America before the continents fully separated.
