Build a T. rex skeleton 💀
Drag each bone from the tray onto the shadow. It snaps when it's close. (Keyboard: Tab to a bone, press Enter to place it.)
🏛️ Real museum mounts
Most skeletons you see in museums are lightweight casts. The real fossil bones are heavy and fragile, so they're kept safe for scientists to study.
🧩 Missing pieces
Complete skeletons are very rare! Scientists fill gaps using bones from other individuals or copies of the matching bone from the other side of the body.
