How I am supposed to remember all this?• If a thyreophoran walked beside you, it would
scrape your thigh because of all the scutes on its body.
•Ornithologists study birds and ornithopods have beaks like a duck (bird )
• The margins of your paper are around your paper and ceph- means head, so marginocephalians have stuff going on around their heads.
•Sauropods are the largest dinosaurs, so if they stepped on you, you would be sore.
•Theropods would eat you, so they are blood thirsty.
