The discovery of Silesaurus from Poland and the recognition that Herrerasaurus and Eoraptor may not be theropods have forced a re‐evaluation of saurischian and theropod synapomorphies. Here, we re‐evaluate each purported Triassic dinosaur from North America on a specimen by specimen basis using an apomorphy‐based approach. We attempt to assign specimens to the… CONTINUE READING
