Stegosaurus 1997 Skin B?

[Urufu1997]

Is this a Bug or is there really no 1997 Skin B for the Stegosaurus? Was Skin B maybe accidentally named 1997_Skin_C?

Isn't it unlocked in challenge mode?

I've played only the Campaign of Return to Jurassic Park and I don't know why it should only be available in Challenge Mode

Edit: OK, just found out I need to play Challenge Mode to be able to use some Skins

Thanks for the Response
