For those who don't know how your data looks like, it's probably most helpful to post an few entries from mature.fa to help you filter.

grep -A 1 "sapien" mature.fa > human.fa should be all you need.

Alternatively you may be able to selectively download things from RNACentral. See this example. Limit datasets by options in left column.
