Buried in Stone for 150 Million Years, Intact Dinosaur Eggs Found Preserved Exactly Where a Jurassic Predator Laid
The Daily Galaxy • • science
Key Points:
- Researchers from the Torres Vedras Natural History Society discovered a 150-million-year-old dinosaur egg nest embedded in granular sandstone along Santa Cruz beach cliffs in Portugal, dating to the Upper Jurassic period.
- The eggs were found in an orderly arrangement, suggesting an original nesting site rather than displacement by water, with sediment indicating a rare riverbank nesting environment for carnivorous dinosaurs.
- Almost all hatchlings appear to have successfully emerged, with potential embryo remnants possibly preserved inside the sediment block, which will be examined using computed tomography scans and microscopic analysis.
- The three-dimensional preservation of the eggs in an unusual sandstone matrix challenges conventional assumptions about dinosaur egg fossilization and nesting behaviors during the Jurassic.
- This find contributes to the growing record of
