What do you think the age of the Gastropod and Ammonite would be in relation to the Trilobite?

Gastropods and ammonites appeared after trilobites, which thrived during the Paleozoic Era, particularly in the Cambrian to the Permian periods. Trilobites existed roughly from 521 to 252 million years ago, while gastropods first appeared in the late Cambrian and became more prominent in the Mesozoic Era. Ammonites emerged later, around 400 million years ago, and flourished during the Mesozoic, particularly in the Jurassic and Cretaceous periods. Thus, both gastropods and ammonites are younger than trilobites.
