Scientists uncover fossilized dinosaur eggs in America, dating back 100 million years

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.
