💎 The large stibnite crystals are made up of tiny building blocks called unit cells, in which atoms and sulfur combine in a regular arrangement. Unit cells repeat in a 3D pattern to form a crystal.

🎊 Happy New Year to all—we hope to see you at the Museum in 2024!

This Fossil Friday, meet an exceptionally preserved feathered dinosaur. Sinornithosaurus millennii lived some 130 million years ago and was about 3 ft (1 m) long. When it was discovered, it joined a growing list of dinosaur fossils showing evidence of feathers. But this specimen is especially unique because the imprints of its feathers are astonishingly clear. Scientists think Sinornithosaurus had three types of feathers: simple hairlike filaments, downy tufts (like those on modern birds), and modern feathers along the edges of its limbs!
