Review and photos by Griffin
Tenontosaurus was an Iguanodontid ornithopod dinosaur that lived in the Western United States during the early Cretacious period. In life it would have co-existed with dinosaurs like Iguanodon, Dienonychus, Utahraptor and Acrocanthosaurus. Thanks to a Tenontosaurus skeleton discovered with Dienonychus chew marks on its bones in addition to Dienonychus skeletons nearby, the idea of pack-hunting Dromaeosaurs is now widely accepted. Unfortunately this has also lead to the image of poor Tenontosaurus to ALWAYS be the prey item for Deinonychus. (Seriously, google image search “Tenontosaurus”. Like 80% of the images that pop up will be of it being attacked and/or eaten by the Deinonychus.) Medullary bone tissue, which is used by modern birds for laying eggs, has also been found on the bones of Tenontosaurus fossils.
