Digging Dinosaurs” presents those aspects of dinosaur exploration and discovery that really interest people:

From my 10 years of field experience, I tell you how it actually feels:

  • to spend weeks in the blistering heat and dust of the Badlands.
  • to meet that rattlesnake or scorpion you really weren’t expecting.
  • to look for (and find!) exciting fossil remains of dinosaurs and other animals that are over 70 million years old.
  • to spend hours — or days — carefully extracting these bones from the surrounding rock and transporting them to the museum.
  • to spend days — or weeks — gently cleaning and preparing them for storage or display.

If time and numbers permit, I wind up the program by inviting audience members to handle real dinosaur fossils and discover how easy it is to tell the difference between bone and rocks. How do you know it’s really dinosaur bone? Find out for yourself!

Dino Fun Facts
Were dinosaurs warm-blooded, or cold blooded, or something in between?

click here for answer

So, where do dinosaurs fit in? The most likely answer is that different dinosaurs had different strategies for maintaining their internal body temperature. Small animals may have been warm-blooded and fossils are now showing many smaller dinosaurs had non-flight feathers to help hold in their body heat. Huge dinosaurs may not have needed the high metabolism needed for warm-bloodedness simply because their large bodies stored sufficient heat from sunset to sunrise.

The more we understand about modern animal metabolism, the more we see that the "either/or" distinction between warm- and cold-blooded is too simple. There are many animals that have a metabolic strategy somewhere between these two extremes.
