A bipedal walks on two legs (e.g. humans); a quadrupedal animal walks on four legs (e.g. dog, cat, etc.).
Triceratops was a quadrupedal land animal. It didn't have wings or fins, and technically the end of the forelimb is a foot, not a hand, unless the animal is at least partly bipedal. Its front feet each had three toes.
Bipedal describes a manner of movement in which one moves using two legs or feet. (Biped in latin is literally "two footed") Humans are bipedal, as are some animals like kangaroos or some primates, although the term is not restricted to describing living organisms. Animals like dogs and cats are considered quadrupedal, as they move on four limbs.
A animal that normally walks on two legs is called 'bipedal'. On the other hand, a four legged animal is a 'quadrupedal'. Examples of bipedals are kangaroos, birds, and humans. Many dinosaurs were also bipedals.
Zebra, tiger, lion, frog, cat...humans are the only species that are bipedal. Any animal but a human, take your pick.
