You probably did.  "Ornithopsida" isn't really a name that would be that 
hard to come up with by two different people.  It only means "bird faces".  
Real easy to come up with considering that Sauropsida is "lizard faces" and 
Theropsida is "beast faces".

Is this what you put in your groups?

Theropsida = Mammals, "Pelycosaurs", Therapsids

Chelonopsida = Turtles and more basal anapsids

Herpetopsida = Lepidosaurs

Suchopsida = Crocodiles and their extinct relatives

Ornithopsida = Dinosaurs (inc. Birds) and Pterosaurs

wouldn't be exactly the same though as mine as what I called "ornithopsids" 
were archosauromorphs.
