Have you ever thought about how exciting it would be to make an important scientific discovery? In paleontology, anyone with a love of science and discovery, some patience, eagle eyes, and a willingness to get dirty has a chance of doing just that! Amateur fossil hunters have discovered new species, assembled important collections, and collaborated with professionals to write groundbreaking scientific papers. Many have donated their fossil discoveries to museums around the world so that visitors can see them and future generations of scientists can study them. Amateurs have also worked to preserve important fossil sites threatened by development or destruction.

Our understanding of Cretaceous life in Maryland would be much less complete without the dedicated work of several amateur paleontologists who have worked with Smithsonian and university scientists to describe and document their finds. Here we profile three whose fossil discoveries are on display in the “Dinosaurs in Our Backyard” exhibit at the Smithsonian.

Ray Stanford

Ray Stanford holds a rock that has many small dinosaur tracks.
Ray Stanford began collecting Cretaceous fossils when he retired to Maryland in 1986. Over the years, in stream beds throughout the area, he discovered hundreds of dinosaur tracks and other important and amazing evidence of animal life in the Washington DC area 110 million years ago. One of his favorite discoveries was the imprint of the baby nodosaur Propanoplosaurus, which is now on display in the “Dinosaurs in our Backyard” exhibit at the Smithsonian's National Museum of Natural History. This specimen is the subject of his latest scientific paper, written in collaboration with Johns Hopkins University professors David Weishampel and Valerie B. Deleon.

Thomas R. Lipka

Tom Lipka in the field.
Thomas Lipka works for the City of Baltimore and collects and studies fossils in his spare time. He has donated dozens of local Cretaceous fossils to the Smithsonian, including the type specimens of a turtle, Arundelemys, and a mammal, Arundelconodon. (A type specimen is a fossil that differs from all previously described fossils and becomes the basis for defining a new species.) He has collaborated with numerous scientists to describe and analyze his discoveries, and has published several research papers.
