Abstract
Zoology and Paleozoology are two complementary approaches to the study the animals as global entities. Respective contributions of both fields bring t o each other mutual profits, even if the zoology supplies more information, in various topics using essentially as material the soft parts of the orga nisms (morphology, anatomy, histology, embryology, morphogenesis, physiolog y, systematics, taxonomy, phylogeny, genetics, biochemistry). Paleozoology, having priority on hard and fossilized parts of the organisms, supplies fu ndamental and necessary documentation on the historical dimension of the ev olution in correlation with time, and reinforces the evolutive theory. Argu ments and limits of the respective contributions of zoology and paleozoolog y are illustrated by some examples, selected principally from two phyla of invertebrates, the Bryozoa and the Brachiopoda, principally the genera Pseu dothyracella, Electra, Arachnidium, Alcyonidium, Terebratulina and Neocrani a; but other interesting topics of discussion have been choosen in other ph yla (Mollusca, Echinodermata, Arthropoda). Infortunately, many phyla with g reat phylogenic interest are not fossilized; consequently much fundamental information is land always will be) lacking.
