In some cases a fossil may consist of all or part of the original organism. Example Amber
Original material
Amber is a unique case when it comes to fossils because it is a type of organic material that preserves organisms in almost pristine condition. Amber is fossilized tree resin, and often when an organism becomes trapped in the sticky resin, it is quickly covered by more layers of resin, preventing decomposition and providing a stable environment for the organism to be preserved in.
As a result, when we find amber fossils, we often find that they contain all or part of the original organism. For example, we might find an insect trapped in amber that still has its wings, antennae, and body intact. This level of preservation is incredibly valuable to scientists because it allows us to study the original form and structure of the organism in great detail.
Overall, while amber fossils are relatively rare, they provide a unique window into the past, offering us insights into the composition and behavior of ancient organisms.
