Bring on the Beaks!By
Some ceratopsians (ser-uh-TOP-see-uns) were big. Some were small. But they all ate plants. And they all had beaks!
Psittacosaurus (sih-TAK-oh-SAW-rus) walked on two legs and was the size of a large dog.
Aquilops (AH-kwi-lops) was only as big as a pet cat!
Zuniceratops (zoo-nih-SEHR-uh-tops) plodded along on all fours. It was larger than an elephant and had giant horns!
