O. Boeuf et D. Gilbert, PRESENCE OF TESTATE AMEBAS (GENUS, TRINEM A), IN THE UPPER PLIOCENE, DISCOVERED IN THE LOCALITY OF CHILHAC (HAUTE-LOIRE, FRANCE), Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 325(8), 1997, pp. 623-627
The locality of Chilhac (Haute-Loire, France) has yielded an abundant
fauna of vertebrate (fifteen fossil mammal species and three fossil bi
rd species). The existence of plant prints were revealed lately, they
concern endocarp prints of the genus: Prunus. Recently, the discovery
of smaller splinters of parts of the plant, which were moulded by volc
anic ash, were studied by scanning electron microscopy. They show, for
the first time in Upper-Pliocene, the presence of Testate Ameobae of
the genus Trinema.
