Ancyloceras matheronianum is an extinct species of heteromorph ammonite cephalopod belonging to the family Ancyloceratidae. It is the type species of the genus.
These fast-moving nektonic carnivores lived during the Cretaceous period, Lower Aptian age (from 125.45 to 122.46 Ma). [1][2] Fossils of this species are found in the marine strata of France, Russia and Morocco.
Description
Ancyloceras matheronianum ammonites have quite large shells, reaching a length of about 30–40 centimetres (12–16 in). They are heteromorph shaped, with a partly uncoiled shell and the aperture directed toward the coiled part.[3]
