I cannot directly provide you with a PDF of "Fossils and Aquarium" by Camille Saint-Saëns. There's no widely known or readily available PDF of a work with that exact title. It's possible:
- The title is slightly inaccurate: The work you're seeking might have a different title, or "Fossils and Aquarium" might refer to two separate pieces by Saint-Saëns. Many composers have works with similar thematic titles or descriptions.
- It's a lesser-known or unpublished work: Some composers have works that aren't as widely published or digitally available.
- It's a misremembered title: It's possible there's a mistake in the title you've provided.
To help you find the music you're looking for, please provide more information:
- Full title: If you can remember any part of the full title, this will be extremely helpful.
- Genre: Is it a symphony, a piano piece, a song cycle, etc.?
- Instrumentation: What instruments are involved? (Piano solo, orchestra, etc.)
- Any other details: Do you remember anything else about the piece, such as the year it was composed, or any movements or themes?
With more accurate information, I can assist you further in your search through online music libraries and databases. You might also find success searching online music retailers (like Sheet Music Plus) or contacting music libraries and archives specializing in classical music.
