Scientists Able To See Preserved Dinosaur Embryos Inside 200-Million-Year-Old Eggs

Massospondylus Carinatus Synchrotron Scan

Kimberley ChapelleThis unprecedented image has allowed researchers to see inside dinosaur eggs like never before.

Scientists used a stadium-sized particle accelerator to scan 200-million-year-old dinosaur fossils — and then created 3D reconstructions of the skulls of baby dinosaur embryos.

The results of the remarkably detailed scans and 3D reproduction have offered unprecedented insight into how young dinosaurs developed.
