I visited the dinosaur exhibit at the Perot Museum of Nature and Science in Dallas. Outside sat huge frogs for children to climb onto.
Inside the exhibit, a tyrannosaurus rex skeleton, found in Montana, is shown near a stuffed mountain lion, so you can realize how big that creature was. It ate meat, but herds of herbivorous dinosaurs roamed North Texas. Imagine having to eat enough plants to sustain a body that big. You’d be hungry all the time. The second picture shows the full skeleton of the tyrannosaurus rex. The largest complete skeleton found was 40 feet long. Several of the skeletons were found in Texas.
I watched a 3D film about a dinosaur, which died 67 million years ago. It was strange seeing the neck and head of a dinosaur stretching out into the theater so close to me. I learned some dinosaurs could see as far as seven miles on a clear day. Potential prey would have a hard time hiding from them. The next picture is of a tenontosaurus from the early cretaceous period. The skeleton was found in Wise County, Texas.
When archaeologists find bones, they cover them with burlap soaked in plaster, which dries. Then the bones are transported to be cleaned and assembled. At the museum, an archaeologist worked to remove dried soil from an artifact.
The skeletons reminded me of a book by Russell Ferrell, The Bone War of McCurtain County, (2018) a true story of Arkansas hillbilly Cephis Hall and Choctaw Indian Sid Love, two backwoods naturalists who sought buried treasure and nature’s booty in the American South (Oklahoma). Their troubles began after they discovered and excavated a world-class dinosaur specimen on land owned by a major timber corporation, which propelled them into a drawn out conflict with the company and its friends in government and academia.
Geologists blame Dinosaurs’ extinction on several likely causes, climatic change, diseases, changing plant communities, and geologic events. Perhaps a giant meteor that crashed into the earth near the Gulf of Mexico in the Chicxulub Crater near the town of Chicxulub on Mexico’s Yucatan Peninsula, caused dust clouds and carbon dioxide that blocked sunlight and killed plants and animals. The crater, which extends out into the ocean, is estimated to be 62 miles wide and 19 miles deep. The megasunami would have reached Texas and Florida.
I also visited the Perot Museum’s extensive rock and mineral collection as well as exhibits on oil wells. It was amazing to see how far horizontal drilling can be extended beneath the surface to collect gas and oil.
Parking was handy, but cost $10. General admission ranges from $13 -$20. 3DFilms are $6-$8. Tickets for $25-$30 include admission and two 3D films. Special exhibits like the dinosaur one cost extra.
