What about say... sinensis, Iguanodon or Tyrannosauridae? Are those technically singular or plural? Or is sinensis an adjective or something?

I explained the distinction and why adding "the clade Theropoda" or "the group Theropoda" makes the singular okay. Higher category names MUST be Latin plurals, period, just as "data" is plural in correct grammar. Arguably, they could have written the sentence as "The Euarchonta hypothesis is similar to the morphology-based Archonta hypothesis"--but they didn't. "Theropoda are similar to the apomorphy-based Avepoda..." is correct grammar in this case. Add the word "clade" and the singular is required.
