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

Bajadasaurus

This spiky-necked Argentine sauropod turned heads with forward-curving spines stretching up to three feet from its neck vertebrae. Named in 2019, Bajadasaurus basically wore a permanent mohawk that likely protected its neck from predators. The unusual forward angle of the spines created a defensive fence around its vulnerable throat. This Early Cretaceous dinosaur looked ready for a prehistoric punk rock concert.
