South of Wellington Utah, reached by a 40-minute drive on mostly dirt roads is a dinosaur quarry you’ve likely never heard of but is known worldwide if you are a paleontologist (A person who studies dinosaurs).
It is worth the trip if you like dinosaurs and are traveling in the area to stop here to see the displays, bones, and quarry exhibits. There is also a walking path you can explore leading you around the digging areas.
There is a separate building a short distance from the main building that houses an actual quarry dig where you can see the bones that have been uncovered.

Two interesting facts about the quarry

According to the descriptions from the displays, more than 12,000 bones from 70 different animals have been excavated at the quarry and are now in exhibits all over the world.
Another unique feature is that the Allosaurus makes up over two-thirds of the dinosaurs found at the quarry. Many of the specimens are juvenile and adolescent Allosaurs and the sheer number has given researchers an unprecedented opportunity to do an in-depth study of the species as a whole rather than just an individual dinosaur.

History of the quarry

Back in the 1920s local cowboys discovered large black bones that clearly were not the bones of their livestock. Eventually, University of Utah geologists investigated the area in 1928 and unearthed about 500 bones.
The sights’ reputation grew and ten years later paleontologists from Princeton University came to excavate bones for their museum exhibits. Today researchers from all over the world come here to study and help with excavations.
