Well actually...if we are getting technical, the tooth of iguanodon was discovered first but described after Megalosaurus (though the famous 'Scrotum humanum' may also be from Megalosaurus which predates both). Thecodontosaurus (also a dinosaur) was known even earlier but not recognised as such. (Well obviously it couldn't be recognised as a dinosaurs as they didn't exist then as it were, but it was not identified as being anything big, or different or interesting).
And yes, Iguanodon does have thumb spikes that were originally misidentifed as nose horns, their function is uncertain but egg-cracking seems pretty unlikely. Sorry for all this unnecessary detail, comes with the job...
