Hey

Natasha was especially interested in dinosaurs; however, Jorge wanted to check out the huge collection of precious gems.
You need to use a semicolon before however because you are connecting two independent clauses into one compound. 
Natasha gazed into a replica of a cooking fire and began to imagine sounds:a crying baby, the persistent click of stone on stone involved in making scraping tools, and the thunderous cry of a mastodon. 
You need to use a colon to indicate that a list will ensue.
