A mold fossil is
a fossil that is formed when an organism dies and is buried in sediment. Over time, the organic material of the organism decomposes, leaving behind a cavity in the shape of the organism. This cavity is called a mold fossil. Mold fossils can preserve the external features of the organism, such as the shape and texture, but not the internal structures. They can provide valuable information about the shape and size of extinct organisms and can help scientists understand the evolutionary history of life on Earth. Mold fossils are often filled with sediment or minerals, which can later harden to become a solid fossil called a cast fossil.
A mold fossil is a type of fossil that forms when an organism, such as a plant or animal, is buried in sediment and then decomposes, leaving behind an empty space or "mold" in the shape of the organism. The mold fossil is formed by the surrounding sediment hardening into rock, preserving the shape of the organism.
A mold fossil is a type of fossil formed when an organism, such as a plant or animal, is buried in sediment, and over time, the decayed remains dissolve and leave behind an empty space or cavity in the shape of the organism. This empty space is known as a mold. Mold fossils are typically formed in soft sedimentary rocks, such as sand or mud, and they provide valuable information about the shape and size of the organism that once occupied the mold.
