Adult Deinonychus, however, were much smaller than adult Tenontosaurus, and it is unlikely a single Deinonychus would have been capable of attacking a fully grown Tenontosaurus.
Odrasli su Deinonychusi, međutim, bili mnogo manji od odraslih Tenontosaurusa, pa nije baš vjerojatno da bi jedan Deinonychus bio u stanju ubiti potpuno odraslog Tenontosaurusa.
