which organism was most likely to live at the same time as brachiopods?
○ placoderms
○ ammonites
○ gastropods
○ trilobites

Explanation:

To determine the organism that lived at the same time as brachiopods, we refer to the fossil record and geological time periods. Brachiopods and trilobites are both marine organisms that were abundant during the Paleozoic era, particularly the Cambrian and Ordovician periods. Placoderms (armored fish) appeared later in the Paleozoic, ammonites in the Mesozoic, and gastropods have a longer range but trilobites are more closely associated with brachiopods in early Paleozoic.

Answer:

D. trilobites
