How to Sign "Dinosaurs"
To sign 'dinosaur', hold your non-dominant arm horizontally across your body with the hand flat and palm facing down. Form a 'D' handshape with your dominant hand by pointing your index finger up while your thumb and other fingers form a circle. Rest the elbow of your dominant arm on the back of your non-dominant hand, and sway your dominant forearm back and forth a few times, mimicking a dinosaur's long neck moving.
