Artistic reconstruction of a newly hatched troodontid-like dinosaur resting among fragments of its eggshell (loosely based on Mongolian microtroodontid-type). These eggshells, when buried within ancient soil, interacted with meteoric waters, leading to early uranium incorporation into the eggshell calcite crystals. Credit: Eva Utsukiyouhei (宇津城遥平)

Scientists found a hidden clock inside dinosaur eggshells
