I am not for certain, but I am pretty sure they are multicellular.
Since multicellular means having more than one cell, dinosaurs were multicellular.
Dinosaurs were multicellular organisms. They were large reptiles that existed millions of years ago during the Mesozoic Era. To determine whether dinosaurs were multicellular or unicellular, you can utilize various resources such as textbooks, scientific articles, or online databases. These sources provide extensive information about the characteristics, classification, and fossils of dinosaurs. By studying the fossil records and scientific research, experts have concluded that dinosaurs were indeed multicellular due to their complex skeletal structures, reproductive systems, and evidence of social behaviors.
