Bat Wakes Up After 30 Years and Goes After Bus Full of Teens

I saw a movie about a bat creature that had slept almost 30 years underground and one night awakens and starts hunting again before going back to sleep.

His main target is a bus full of teens, who have been on a field trip. Their bus runs out of gas in a corn field and they are stuck there with the creature and the bat starts killing them one by one.

I'd like to know what it's called - I really want to see it again.
