Fossil remains for this Dinosaur have been found in Western United States

This dinosaur is a good example of why it pays to take notes. Dyslocosaurus was "discovered" already mounted in a museum. No one seems to know exactly where it came from! It was a medium sized long-necked plant-eater, but it can be anywhere from 70 million to 150 million years old.

The Dyslocosaurus fossils were located in a confusing rock formation in Wyoming, and may date from any time between 150 and 70 million years ago. This is why it was given the name "Hard to place lizard." The remains were from one animal, consisting of parts of the hind limbs. Like Camarasaurus  it had four distinct foot claws, rare among sauropods. The exact location of where it was collected remains a mystery, hence the confusion about its age. If it were indeed a late Cretaceous dinosaur, it would be a rare find.

It is likely that Dyslocosaurus was a typical Diplodocid, about 55 feet long, with a long neck, long whip-like tail, and a massive body with four thick legs.
