Fossil Canyon

Fossil Canyon is the second course of the Dino Domain area of Timber Island and the second overall track in Diddy Kong Racing and Diddy Kong Racing DS. The player must have at least two Golden Balloons to race on it, and seven for its Silver Coin Challenge (or Balloon Touch Challenge in the DS remake). Fossil Canyon takes place in a barren, sandy canyon during sunset, as shown from the orange sky. At the start, the large, yellow sun is shown looming behind a cliff.

This level offers considerably great challenges for new racers. The track has numerous Power-Up Tokens, exclusively in the game's remake, and many Zipper pads. Notorious for its fork in the road, both ways are quick. If the racer travels towards the left side, they will find a red balloon with a missile, but the other route has green and blue balloons for an offensive or defensive attack. It does not feature any moving obstacles, but it does have palm trees which slow down players.

In the original version, a few clips take place in the last part of Fossil Canyon, with the fork in the path. It first appears in the clip that introduces Bumper, who is racing a yellow dinosaur which is running on the adjacent path. The last scene of the whole sequence, which introduces Wizpig and Diddy Kong, takes place in Fossil Canyon. In the scene, several racers are fleeing from Wizpig. Diddy comes into view, flying a plane, and maneuvers under a thick log, which Wizpig crashes into.

Track layout
The track begins as a straight road with palm trees on the side. The road slowly curves to the left, and a giant dinosaur walks around off-track. Racers can then find a Red Balloon, which then leads to a lake, in which the path curves around. Racers can either collect the Bananas on the road or shortcut across the lake by using a nearby Zipper. This leads them in a tunnel, with a Red and Green Balloon lying outside of its entrance.

The tunnel starts with a sharp turn to the left. The path goes briefly straight until taking a sharp turn to the right, where players can find two Green Balloons, two Red Balloons, and a Blue Balloon. Racers have an option to exit the tunnel from a Zipper. The tunnel leads outside to a bump with a Green Balloon in the center. After crossing the threshold, racers drive into a roadless canyon portion. It has two paths, the left one is narrow and bumpy and only has a Green Balloon beneath the small overhand. The right path is wider but has two Green and Blue Balloons. The paths intersect, and lead racers off small ramp with Bananas behind it. The racers enter back on the road and drive a straight pathway to the finish line.

Silver Coin locations
Like the other courses, Fossil Canyon has eight Silver Coins scattered in its area in the Silver Coin Challenge of the original version. The player can access this challenge after winning against Dino Domain's boss, Tricky the Triceratops.

Adventure mode
