One of the enemies Sabre and Krystal would encounter in Dinosaur Planet were these robotic Scorpion-like automatons, typically found in Krazoa-build strongholds such as the Force Point Temples and Cape Claw. While removed in the final Star Fox Adventures, they could still be found hidden within the E3 2002 kiosk version via hacking.

Contrary to popular belief, Shigeru Miyamoto and Nintendo did not singlehandedly force Rare (who was never even fully owned by Nintendo) to convert Dinosaur Planet into Star Fox Adventures. It was merely an offer and suggestion Miyamoto gave to Rare, and at the very least, the higher ups such as the Stamper Bros. and Kevin Bayliss were on board with it. An October 2004 edition of Rare's Scribes says as such:

Found within the files of Star Fox Adventures is an unused audio track for the WarpStone's introduction cutscene, which also includes verbal dialogue. This was clearly an earlier version before Rare had done a voice-acting retake.

Most notably, the music that plays in the background is a remnant from Dinosaur Planet, from the scene where Krystal first arrives in SwapStone Circle and thus meets her respective SwapStone, Rubble. In the final Star Fox Adventures, music performed by bagpipes is played instead in this particular cutscene.

The life bar icons for the SnowHorn and HighTop in Star Fox Adventures sport different, more cartoony designs from their respective in-game models. The reason for this is because they're clearly based upon their original N64 Dinosaur Planet models, which too are much more cartoonier than the final SFA models that go for a more semi-realistic look.

The floating planetoid representing CloudRunner Fortress on the world map screen in Star Fox Adventures very clearly resembles its original, rockier iteration from the Nintendo 64 version of Dinosaur Planet, as opposed to its remodeled look in the final Star Fox Adventures.

In the original Dinosaur Planet, Krystal would come across a pachycephalosaurid dinosaur at CloudRunner Fortress, who is revealed to be one of the SpellStone guardians, who also gives Krystal the Illusion spellpage to bypass the SharpClaw guards within the dungeon. In-game hints and task summaries reveal him to be of the "BoneHead" tribe.

This individual would appear in the final Star Fox Adventures, with his role slightly rewritten as the chief engineer at CloudRunner Fortress (The Queen CloudRunner took over his original role as the SpellStone Gatekeeper for this area). Talking to him in a cutscene will reveal his name to be "Gradabug". While not mentioned anywhere in-game, the Star Fox Adventures Nintendo Power guidebook reaffirms him belonging to the BoneHead tribe.

There's a fairly common misconception that the character of Krystal was originally meant to be a cat in Dinosaur Planet, prior to being redesigned as a vixen when the project was transformed into Star Fox Adventures.

The reality is that despite having a somewhat feline look, Krystal was always intended to be a fox as early as Dinosaur Planet, her original backstory even claiming that she belonged to the "Vixon Tribe" on planet Animus (Sabre and Randorn on the other hand belonged to the "Wolven Tribe", as they were both wolves). Former Rare artist Kevin Bayliss has stated multiple times that she was meant to represent a stylized arctic fox in particular.

According to Takaya Imamura in a 2002 interview with Nintendo Dream, a lot of time was spent between Rare and Nintendo brainstorming on what kind of equipment and weaponry Fox should have during the transition from Dinosaur Planet to Star Fox Adventures. Imamura wanted Fox to use a gun, similar to his original EAD-created prototype of Star Fox Adventures before it was merged with Dinosaur Planet. However, this was not well suited for the Zelda-esque framework established by Dinosaur Planet, so this was abandoned and they embarked on a long period of trial-and-error to determine what weapon Fox should use.

After experimenting with ideas such as a whip, or a gun and sword combo (possibly based on how Fox was already using Sabre's sword in the leaked Dinosaur Planet build), Rare and Nintendo finally settled on Krystal's staff. Imamura claims that this was decided upon because it was a weapon that doesn't require the player to slash the enemy, as he felt uncomfortable with the idea of an animal character like Fox being able to decapitate opponents.
