Ok to answer everyone's requests (btw sorry if I mention you guys because I can't do this ^ for all of you guys in one single reply)
@ScaryLookinHobo: Please specify on which family you want the Dilophosauridae into.
@Shi reincarnated: Sphenacodontidae has already been taken by Tyrannosauridae, only dinosaur families can get up to 2 Paleozoic families max due to how many there are in the Paleozoic.
@Mediterranean Mapper: I'll make this one an exception but I will change it from Drepanosauria to Drepanosauridae if that is fine with you
@Concaventor Wrangler: Placodermi is a class not a family, so I'll change it to Ankylosauridae to Palaeacanthapsidae (which is a family of Placoderms), and plus its the other way around same with 3.
