Lophorhothon Carcass

This illustration depicts a likely explanation for why the fossilized remains of prehistoric land animals, such as Lophorhothon, are found in marine deposits. This representation of the "bloat and float" hypothesis of deposition, which includes the likely predator activity, provides a graphic view of the reason why few intact skeletons are found.
