Professors of an online graduate-level paleontology class developed the concept of marquee fossils—fossils that have one or more unique characteristics that capture the attention and direct observation of students. In the classroom, Marquee fossils integrate the geology, biology, and environmental science involved in the study of fossilized organisms, their paleoenvironments, and subsequent changes in Earth since their existence. This article discusses the concept of marquee fossils and teachers’ development of marquee-fossil activities for their classrooms.
