A substantial hurdle is the difficulty of working out fossil ages. Paleontology or Palaeontology ( / ˌ p æ l ɪ ɒ n ˈ t ɒ l ə dʒ i /) is the study of prehistoric life.It includes the study of fossils to determine organisms' evolution and interactions with each other and their environments (their paleoecology).As a "historical science" it attempts to explain causes rather than conduct experiments to observe effects. This era of fossils includes fossils found in the Quaternary period, such as pecten gibbus and neptunea tabulata, and the Tertiary period, calyptraphorus velatus and venericardia planicosta.

Neptunea arthritica (Bernardi, 1857) is a dioecious gastropod with internal fertilization and direct development, found in the sublittoral zone to a depth of a few tens of metres. Proceedings of the Academy of Sciences of the Estonian SSR. Inflict Poison damage equal to ATK x10 to all enemies every turn. Beds that preserve fossils typically lack the radioactive elements needed for radiometric dating.This technique is our only means of giving rocks greater than about 50 million years old an absolute age, and can be accurate to within 0.5% or better.
