Which is more likely to form a fossil turtle or a tarantula?

A turtle is more likely to form a fossil than a tarantula due to its hard shell, which provides better protection and preservation during the fossilization process. Turtles have a bony structure that withstands decay, while tarantulas, being soft-bodied with exoskeletons, are less likely to be preserved in the fossil record. Additionally, turtles have existed for millions of years, increasing the chances of finding fossilized remains compared to tarantulas.
