Extraterrestrials and Dinosaurs.

Tyco made in 1987 "Dino Riders". Little men with dinosaurs.
The line was an interesting adendum to the alien action figures Universe, introducing strange alien beings with animal like faces that came from a distant planet in the age of dinosaurs, The Jurassic period.

They used dinosaurs like vehicles to fight their enemies, Evil Rulons.

Absolutely unforgetable.
