Breakthrough is a short film anthology and educational outreach program from the Science Friday Initiative and Howard Hughes Medical Institute (HHMI) Tangled Bank Studios. This short documentary series follows women working at the forefront of their scientific field, blending deeply personal stories with innovative research and discoveries. Watch the latest season of the film series at BreakthroughFilms.org.

When paleontologist Jingmai O’Connor looks at the abdomen of a small, ancient avian fossil, she gets a thrill when she spots a jumble of nodules, no bigger than a scattering of goosebumps, protruding from the creature’s bones. Their presence could mean the animal’s metabolism supported rapid egg growth. In another specimen, O’Connor discovers an entire bird gobbled up inside of a chicken-sized feathered dinosaur, revealing a clue about the ecology in which both animals lived.

O’Connor’s obsessive eye for detail and encyclopedic knowledge of morphology comes in handy when she’s placing these fossils on the ancient family tree of birds. She credits those skills, as well as her enthusiasm for science, to her mother, a geochemist who earned her PhD while raising O’Connor and her three siblings. It was also her mother’s influence that led O’Connor to focus on geology—and to explore her own Chinese-American roots—by focusing her studies on the scores of bird fossils coming out of China at the turn of the century.

Dozens of discoveries later, O’Connor is now a professor at the Institute of Vertebrate Paleontology in Beijing where she uses the world’s largest collection of avian dinosaurs to explore the changes in ancient species that led to wings, tail feathers, flight, and many other adaptations seen in modern birds.
