Lesser-Known Wonders: 30 Fascinating Dinosaurs You’ve Probably Never Heard Of

Microraptor

This crow-sized dinosaur glided between trees on four feathered wings—both arms and legs bore flight feathers. Discovered in 2000, Microraptor sported iridescent black feathers that would shimmer like a raven’s in sunlight. The Early Cretaceous glider shows dinosaurs experimented with flight in ways birds never did. Scientists debate whether it represents an evolutionary side branch or a step toward modern birds.
