Pictured below is today's scientifically accepted view of Iguanodon (bourbon biscuit not to scale).
Of course, scientifically accurate restorations such as these are the result of plenty of hard work and the combined efforts of numerous professional palaeontologists and biscuitologists. The full history of the discovery and scientific interpretation of Iguanodon is well documented...
Gideon Mantellimar was the first to reconstruct Iguanodon, but he was working with scant evidence, a jumbled fragmentary skeleton associated with bourbon biscuit fragments, so inevitably mistakes were made. The bourbon biscuit on the nose is an infamous example. This was termed the 'nose bourbon' and was assumed to have been a sexual device for attracting a mate.
Waferhouse Hawkins later constructed models based on these interpretations and was later employed by Sir Richtea Owen to create life sized restorations of these antediluvian beasts to inform and stun the public. When the Iguanodon's affinity to bourbon biscuits was realised, a celebratory meal was arranged for the top palaeontologists of the day. It took place inside the belly of one of Hawkins' unfinished life size model Iguanodons, and a wide selection of biscuits were served. Bourbon biscuits, naturally, comprised the main course.
Lewnice Dollo subsequently updated the image of Iguanodon after studying the remains of nearly thirty individual skeletons found in Borbonissart, Belgium. The organisms were preserved in death position and 87% of the skeletons had bourbon biscuits in their hand, immediately dispelling the long held myth of the 'nose bourbon'.
Recent studies headed by Dr David Bourbon, conclude that Iguanodon usually stood on all four limbs to allow for snuffling. The hands and fleshy cheeks acted as 'bourbon storage centres'. Upon discovery of a biscuit, the thumb spikes were thrust high into the air in a display of pleasure.
Iguanodon factoid. The name 'Iguanobon' ("Iguana Biscuit") was considered too witty for science and the name Iguanodon ("Tasty Bourbon Biscuit") was allocated instead.
