The mid-Cretaceous amber of France contains thousands of protist-like inclusions similar in shape to some ciliates, flagellates
and amoebae. The sheer abundance of these inclusions and their size variation within a single amber piece are not concordant
with true fossil protists. French amber is coniferous in origin, which generally does not preserve well protists without cell walls.
Thus, it would be surprising if French Cretaceous amber had preserved millions of protists. Here, we present a survey of the
protist-like inclusions from French amber and attempt to elucidate their origins.
Diverse Cretaceous ambers (from Spain, Germany and Lebanon), also derived from conifer resins, contain thousands of
