That is a good picture of rhyhorn. I didn't think of the name being switched. I think of word parts in terms of Greek and Latin word meanings. Rhy means nose. This would fit both pokemon has they have horns on their noses. Cer means horns. Rhinoceros is a real life animal, and its name means nose-horn. It is fitting because it shows the most distinctive trait. I have heard of early unicorn sightings being attributed to rhinoceroses. I find that strange. There is a single horn, but rhinos otherwise looks nothing like unicorns. Unicorns are typically depicted as being horse-like. Rhinos may be related to horses, but they really do not look alike. Rhyhorn is a Pokémon based on rhinos. So the name is half translated so it fits well. Don means tooth. So rhydon means nose tooth. I guess it fits as rhydon has a drill-like horn on its nose. The name may be reference from the dinosaur iguanodon. Iguanodon has a name meaning iguana tooth. I am big dinosaur fan. I am so used to the modern and accurate picture of iguanodon. It pretty much looks like a regular bipedal dinosaur. However the old outdated pictures look freaking bizarre. Rhydon has a look that resembles an outdated iguanodon. There is a big stocky body and a horn on the nose. There is a change of posture from being quadrupedal in the first depictions to standing strait up in later depictions. That change is like Rhyhorn evolution. The modern iguanodon is sleeker. It stands on two feet and leans forward. It has thumb spikes instead of a nose horn. Iguanodon is the first dinosaur discovered by scientists. It has changed a lot due to science marching on.
