- noun large duck-billed dinosaur of the Cretaceous period
Sorry, no etymologies found.
Triceratops with its ruffed collar, tyrannosaurus of the fearful teeth, ankylosaurus the plated ambulating tank, trachodon the gentle duck-billed monster-all had vanished.
Prof. Challenger (Wallace Beery) and Prof. Summerlee (Arthur Hoyt) behold the death struggle between allosaursus and trachodon.
We may take it for granted that the pterodactyl and the trachodon had none of the foreboding based on experience which destroys the peace of man.
