Can't wait for the scientific ACKCHYUALLYS on this one.
@designthinkingcomic Since you're asking for it.
Trilobites existed from around 520 million years ago until 250 million years ago. Whereas the cretaceous period lasted from around 140 million years ago to 65 million years ago.
So *actually* it wouldn't make sense for trilobites to complain about temperatures in an era they were not alive for.
