This is the original Marx toys Colossal Fossil Fight game.
Rare to find in this condition.
Each of the two players use a dinosaur to pick up bones from the bone yard and place them into their den. There are three types of bones (legs, ribs, and skulls) which are worth one, three, and five points, respectively. Once all the bones are removed from the bone yard, the player with the most bone points in their den is the winner.
One of the 25 bones is missing; there are 14 leg bones, three skulls and seven ribs.
The instructions are missing.
Box in very good condition, though there is a scuff to the front (see photo)
