Jurassic Park db forum

Visit wikipedia site (link below), in "Trailer Music" section of Jurassic Park site two other trailers are mentioned. I've seen only the last one for sure, and only this one is included in DVD releases of JP series in my country. Any ideas where i can watch/download two first trailers?

I've only seen the last one, but I would love to see the other two. If anyone has them, it would be great if they could post links.
