🦖 You won’t believe the dinosaurs that once called the Midwest home! Uncover the STUNNING world of South Dakota’s prehistoric past. 😲 #Dinosaurs #SouthDakota #DinosaursInSouthDakota
RAPID CITY, SD – South Dakota was once home to a stunning variety of dinosaurs that thrived during the Mesozoic Era. These “terrible lizards”, as their Greek name translates to, were the dominant land animals for a staggering 180 million years. South Dakota’s prehistoric residents included massive herbivores, fierce carnivores, and speedy smaller predators. Today, you can still feel the spirit of these Jurassic giants in the Badlands of South Dakota.
🦕 Discover the Dinosaurs that Once Roamed South Dakota
While most people picture giant sauropods like Apatosaurus or terrifying apex predators like Tyrannosaurus rex when they think of dinosaurs, these animals actually came in a wide range of shapes and sizes.
The largest dinosaur discovered in South Dakota was over 65 feet long, while the smallest was just 5.5 feet from nose to tail! Ok, that one actually sounds pretty cute to me! Hehe.
🗺️ Where to Find South Dakota’s Dinosaur Fossils
Dinosaur fossils have been uncovered in two main areas of South Dakota:
- The Hogback ridge encircling the Black Hills, with dinosaurs from the late Jurassic and early Cretaceous periods (~150-125 million years ago). Rapid City’s Dinosaur Park is located along this ridge.
- The counties in the northwest corner of the state, which have yielded late Cretaceous dinosaurs from around 80-66 million years ago.
🌿 A Lush, Warm Habitat for Dinosaurs
The South Dakota landscape that dinosaurs knew was quite different from today. It featured expansive floodplains, sandy streambanks far from the ocean, and coastal areas near deltas. Parts of the state were even submerged under an inland sea at times, as evidenced by marine fossils. The climate was likely warmer and wetter than present day.

🤝 Partnering to Protect South Dakota’s Fossil Heritage
Fossils provide an invaluable window into South Dakota’s distant past. The public is encouraged to work with museums to preserve the state’s incredible fossil resources for study and education. When significant fossils are found, it’s important to document their surroundings before excavating them. Removing fossils without proper techniques can damage specimens and destroy contextual information.
Those hoping to collect fossils in South Dakota need to obtain permission from landowners for private land, Tribal authorities for Tribal lands, transportation offices for highway areas, and land managers for public lands. Regulations vary by area.
