 Iguanodon material has also been used in the search for dinosaur DNA and other biomolecules . In research by Graham Embery et al . , Iguanodon bones were processed to look for remnant proteins . In this research , identifiable remains of typical bone proteins , such as phosphoproteins and proteoglycans , were found in a rib .
