Preservation of Triceratops horridus Tissue Cells from the Hell Creek Formation, MT

Abstract: Dinosaur soft tissues are shown to be remarkably preserved to the sub-micron level of ultrastructure despite environmental and biological factors associated with burial for millions of years. Light microscopy and scanning electron microscopy (SEM) reveals soft tissue features such as fibrillar bone tissue, osteocytes, and blood vessels. Concerns that these findings relate to contamination or biofilm formation have been refuted. Notwithstanding the controversial nature of these discoveries, soft dinosaur tissues should be systematically searched for and thoroughly characterized in other dinosaur remains.
