Antelope bone fragment in rock from the 3-million-year-old early human site, Makapansgaat (South Africa). Its bone marrow cavity is filled with a white carbonate-rich precipitate. Paleometabolomics can describe the well-being of that animal and provide ultrafine-scale reconstructions of its paleoecology. Credit: Timothy Bromage and Bin Hu, NYU College of Dentistry

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)
