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

A Late Cretaceous face-off between an adult Nanotyrannus (left) and two juvenile T. rex, with a sub-adult T. rex watching from a distance. The scene evokes a preface to the NHMLAC’s famous T. rex trio on display in the Jane G. Pisano Dinosaur Hall. Credit: Jorge Gonzalez

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

Map showing potential migration routes of the human ancestor, Homo erectus, in Africa, Europe, and Asia during the early Pleistocene. Key fossils of Homo erectus and the earlier Homo habilis species are shown, including the new face reconstruction of the DAN5 fossil from Gona, Ethiopia dated to 1.5 million years ago.
