Our museums remain closed due to COVID-19. While LA County Public Health has entered Phase 3 of the Roadmap to Recovery, allowing for the reopening of museums on June 12, our museums are still slowly welcoming back staff and are in the process of planning for new health and safety protocols in our galleries and gardens. Therefore, we will not be reopening until later in the summer. Sign up here to be the first to know when we will safely re-open to the public and in the meantime, stay connected from home.

Dinosaur Feather in Amber
Preserved feathers in mid-Cretaceous Burmese amber

Frozen in time, animals trapped in amber can tell us much about the past. Some of our collections include amber-encased dinosaur feathers from more than 100 million years ago. Using these specimens, NHM’s Dinosaur Institute researchers discovered just how different ancient feathers are from their current counterparts. Using modern technology like microphotography and CT scans, scientists got an up-close and 3D look at the inside of ancient feathers. While modern bird plumage has a central shaft filled with a spongy material, these 100-million-year-old fossils showed a different structure—a thin shaft with no spongey stuff inside! It’s a type of feather we just don’t see anymore. This extinct structure suggests that they grew completely differently from how feathers grow today. Thanks to an ancient sticky situation and modern technology, we are learning more about dinosaurs every day.
