“take a picture with a life-sized T-Rex skull!”

Experience a live lecture program on the T-Rex, other dinosaurs and the great extinction. 65 million years ago in what is now Wyoming, South Dakota and Montana, lived the greatest, most, powerful predator ever to walk the Earth. This was the great Tyrannosaurus Rex. With a five-foot skull packing eight inch teeth, huge jaw muscles and forty-five miles per hour speed, he feared nothing. One of the Northern Wyoming’s newest attractions is the T-Rex Natural History Museum. It is located in Ranchester on Highway 14, the scenic route to Yellowstone National Park through the Bighorn Mountains. In the museum, you can take your picture with a life sized cast skull of a female T-Rex named Sue. Dinosaur diorama includes a Velociraptor, T-Rex vs Triceratops, Allosaurus vs Diplodocus, Ankylosaurus and Parasaurolophus. There are also 1-8.75 scale skeletons of T-Rex’s Sue and Stan.Dinosaur Fossil dioramas explain how dinosaur bones fossilized and also the theory that dinosaurs were warm blooded.There is a beautiful collection of minerals and crystals, including Quartz crystals, Fluorite, Calcite and petrified wood. Also there are Mexican minerals, Tri State crystals, and minerals from Arizona and California.In the gift shop, you can buy quality dinosaurs like T-Rex, Triceratops, Velociraptro and many others. Dinosaur books, mugs, t-shirts and fossils and a beautiful selection of minerals and crystals are offered. There are also Wyoming minerals maps, mineral sets and Native American jewelry.

I wouldn't bother. We added this stop to our road trip because my daughter loves dinosaurs. With the name, "T Rex Natural History Museum" you'd think that it was a decent sized museum with lots of info about T Rex and other dinosaurs, WRONG. It is a very tiny building with more rocks than actual dinosaurs. The picture on Roadtrippers makes it seem like there is a full T Rex skeleton but in reality, it is a cast of the T Rex "Sue" head along with another cast of a Triceratops and that's about it.

Nothing interesting at all about this place. Seems like they have the T Rex cast just so they can suck people in to coming here to sell them rocks. Admission was only $1, anything more I would have asked for a refund.

If I could give negative stars I would. We went out of our way to come here and it was a big waste of time.

Although this site reportedly once held a cast of Sue’s skull, it is now solely a rock shop owned and operated by a very kind US Veteran. If beautiful stones interest you, I highly recommend that you stop. The only Dino items on display (and for sale) are man-made raptor claws...so if Sue is your interest, you’ll have to go to Chicago, Illinois to see the real deal.
