p. 513. A new perspective on Iguanodonlocked

  • David Norman


‘A new perspective on Iguanodon’ discusses developments in our knowledge of Iguanodon biology. A massive haul of Iguanodon skeletons fuelled a popular picture of how the creature lived, but was it accurate? Examination of the casts shows that the tail was broken to fit the researchers’ bipedal hypothesis—Iguanodon actually moved on all fours. This was supported by further data from the forelimbs. Soft tissues are rarely preserved in fossils, but traces of them, such as skin imprints, natural mudstone casts, or indentations from muscles can yield valuable information. Fossilized Iguanadon teeth suggest Iguanodon was herbivorous, but their jaws used a pleurokinetic mechanism, which is different from mammalian plant-eaters.
