Portugal's Coastal Cliff Uncovers Intact 150-Million-Year Jurassic Egg Nest

At a coastal cliff in Santa Cruz, Portugal, researchers uncovered a block containing 10 Upper Jurassic dinosaur eggs (~150 million years old) preserved in three dimensions within granular sandstone, arranged in a natural nest pattern that suggests a genuine nesting site and limited disturbance. The team suspects carnivorous dinosaurs may have laid them, with potential embryonic remains to be confirmed by planned CT scans and microscopic analyses.

Crystal-filled dinosaur eggs rewrite fossilisation stories in China

Two spherical dinosaur eggs from eastern China were found with interiors filled by calcite crystals rather than bones, a rare mineral replacement that preserves internal voids as geometric crystal patterns. The Anhui eggs belong to a new oogenus, Shixingoolithus qianshanensis, while a Ganzhou Basin find yielded hadrosauroid embryos, offering clues about late Cretaceous reproduction and the environmental conditions that drive such preservation near the Cretaceous–Paleogene extinction.

Researchers Uncover Dinosaur Egg Mystery in Surprising Location

Researchers have discovered that many dinosaurs, including Protoceratops, likely laid soft-shelled eggs, which are less likely to fossilize, explaining their rarity in the fossil record. This finding, supported by chemical analysis, suggests soft eggshells were common even late in the dinosaur era and may have been used by marine predators like mosasaurs, indicating diverse reproductive strategies among prehistoric creatures.
