Both would be pretty meh if you ask me... one is known from a partial skull... the other even less... theres no way of giving them a proper restoration or make them unique without getting outlandish.
There are a few SA critters I've considered...
- Eoraptor would be a fine choice, although I've always put it in a Late Triassic pack...
- Megaraptor would be decent...
- Saltasaurus is the original armored sauropod...
- Brachytrachelopan would bring a nice twist to the Sauropod family.
- Buriolestes appears to be on omnivorous prosauropod.
- Alvarezsaurus would make a great insectivore addition
- Stegouros, Piatnitzkysaurus, and Mussaurus.
- Assuming they'd go beyond dinosaurs, Hyperodapedon was always one of my favorite.
