Identification request for anime movie: A boy who loses his parents, fights dinosaurs/monsters and rescues a girl he falls in love with Please help me find this anime movie that I watched in the 1980s: The story is about a boy who travels with his parents on a holiday to some kind of island, then he gets lost, and has to become brave to survive as he fights these monsters/dinosaurs, and kills them with a long spear (half metal half wooden). He also finds a girl whom he protects/teams up with. In the end, his parents find him again, as a transformed brave boy, and they leave all together with the girl he falls in love with.
I think it might be Shounen Kenya  


  This cartoon, based on a popular manga (Japanese-style comic), centers
  on an 11-year-old boy who goes to Africa with his father in 1941.
  Because he is Japanese, the father is detained by the British. The boy
  joins up with a beautiful native girl, and the adventure begins, a
  sort of Young Indy Jones meets Tarzan.



The main character has 1/2 wooden 1/2 steel spear.
He traveled with his parent to a place with dinosaurs.
He rescue a native girl.
