The fossil representatives of the genus
Bouryia were the
subject of a recent study focussing on with the Eocene species of
the Paris Basin and the West of France. In continuation of that work
I add further descriptions while expanding the scope of the study
to include Thanetian (Paleocene) species. To that end, I deal with
the two species already indicated to Thanetian
Truncatella distensa
Cossmann, 1888 and
T. minor Briart & Cornet, 1887 as well as
a species from the Danian of Mons (Belgium)
T. cylindrata Briart
& Cornet, 1887, that I have collected in the Paris Basin from the
Thanetian. A new species
Bouryia roberti is described from the
Thanetian.
