This week on #sciencedeskdigs we learn how inspiring teachers and fossils made geologist Jason Kenworthy realize that he wanted to tell stories from the earth and share the knowledge of the past.
What is it?
This is an ammonite fossil. Ammonites are essentially squids with shells who lived abundantly in the ocean at the same time as dinosaurs in the Mesozoic Era. They are now extinct. Their living relatives are octopus, squid, cuttlefish, and, more distantly, nautilus. They are really cool because they have such a spectacular diversity. You can find some the size of your hand or as big as a desk—and that is not including the tentacles! Some have coiled shells like this one or uncoiled (that look like party hats) or have spiky, ridged, or smooth shells. This one was collected in southern Colorado nearly 18 years ago on a field camp during my undergraduate studies.
I got really lucky throughout my education to having amazing geology teachers who shared their passion for earth science and made the big concepts of science seem tangible by using hands on learning. I’ve had a rock collection since I was old enough to pick up rocks but I didn’t really get excited about fossils and paleontology until college. For that I have to thank Dr. Tom Holtz at the University of Maryland. He was—and still is— one of those professors who has an absolutely infectious love for what they do. That inspired me to want to work with fossils and learn how to tell their stories to others.
That’s what is really awesome about fossils. Each one has so many layers or chapters to its stories like What is it? How did it go about its daily life? How did it mate or capture food? What kind of environment did it die in? How did it die? How did it become a fossil? What happened after fossilization? Who discovered it? Why were they looking for fossils? Where is the fossil now? These all add interest to the specimen and help tell the story of the past on many different time scales.
#Sciencedeskdigs: Ammonite Fossil
Having a desire to tell the stories of the past led me to an internship and later a job as an interpretation and education ranger at Fossil Butte National Monument 16 years ago. Now, I work for the National Park Service Geologic Resources Division on a team that produces digital geologic maps and resource management reports. The goal is to take what is on the map—the fundamental tool that geologists use to describe and understand the geology of a place—and translate it for managers so they can understand the geologic connections to the really cool landscape and history of their park. The reports also provide guidance for how to understand some of the challenges their park’s geology might pose, things like rock slides, or abandoned mines. I like to think of them as practical guides to the geology of a park that are written for anyone that isn’t a geologist!
