Yosef Karo, Translation:Shulchan Aruch — Orach Chaim 52…
“ And if the congregation has already started with Yozer and one does not have time to recite P'sukei D'zimra even with skipping, he should recite the Sh'ma and its blessings with the congregation and pray with them, and afterwards recite all of P'sukei D'zimra without a blessing before or afterwards. ”
