Where to look
From Hanover Point westward, search the dark shingle and clay-washed gravel at low tide — dinosaur bone rolls in the beach gravel looking like heavy black pebbles. The three-toed footprint casts on the foreshore at low water are the free show.
What fossils look like here
Dinosaur bone is black to dark brown with a spongy, bubbly texture — often mistaken for a worn pebble until you feel how heavy it is. Ammonites usually show as a curved ridge poking out of grey rock. Free identification: Dinosaur Isle at Sandown identifies finds in person and runs guided fossil walks.
