Hi all. Adam Pritchard here.
I’ve been thinking about telling the story of my field experience in the Triassic-aged Chinle Formation of northern New Mexico for many years. The Hayden Quarry fossil site at Ghost Ranch has produced the best-preserved and most diverse record of American dinosaurs from the Triassic of North America, plus some of the strangest reptiles that ever lived. I’ve been proud to be a part of the Ghost Ranch field crew for nearly a decade now!

First off, here are some links to exhibits and museum experiences relating to the Ghost Ranch project, including the recent Hayden Quarry discoveries:
The Ruth Hall Museum of Paleontology at Ghost Ranch
Paleontology at Ghost Ranch Jan-Term courses
Shelf Life episode about the Ghost Ranch area and dinosaur evolution.
I thought it’d also be good to add some links to the MANY books scientific papers that have come out of Ghost Ranch paleontology since the beginning of the twentieth century:
