# List of dinosaur specimens with preserved soft tissue

There have been some discoveries of unusually well-preserved fossil dinosaur specimens which bear remnants of tissues and bodily structures. Organic tissue was previously thought to decay too quickly to enter the fossil record, unlike more mineralised bones and teeth, however, research now suggests the potential for the long-term preservation of original soft tissues over geological time, leading to the formulation of various hypotheses regarding the underlying mechanisms involved.
