A leaf would be the most likely to be found as a compression fossil. Compression fossils occur when organisms are buried under sediment and the organic material is compressed over time, resulting in a flattened imprint of the organism. Leaves, being relatively thin and flat, are particularly prone to this type of fossilization. Mammoths, dinosaurs, and shells may be fossilized in other ways, such as permineralization or casts, but leaves are typically discovered as compression fossils.
