This image shows a Porpoceras ventricosum (Buckman , 1914) ammonite fossil. It dates to the Jurassic Period (Toarcien) and was found at Anduze (Gard) France. It was displayed at Muséum National D'Historie Naturelle Jardin Des Plantes Paléontologie et Anatomie Comparée, Paris, France.  Image taken August 2009.

The species was named by British palaeontologist Sydney Savory Buckman (1860-1929). It was originally named by English naturalist James Sowerby (1757-1822) and it was called Ammonites "armatus" (Sowerby, 1815).
