Neoptychites is an extinct ammonoid cephalopod genus from the Turonian stage of the Upper Cretaceous (around 94 to 89 Ma),[1] with a worldwide distribution.
[2] Neoptychites includes extremely involute Ammonitida whose outer whorls have a high triangular section with a moderately rounded venter (the outer rim).
Tho body chamber in adults is generally smooth, with a constricted aperture.
Neoptychites belongs to the ammonite family Vascoceratidae and is included in the subfamily Vasoceratinae.
Fossils of Neoptychites have been found in Austria, Brazil, Cameroon, Colombia (La Frontera (Huila, Cundinamarca, Boyacá) and Loma Gorda Formations, Aipe, Huila),[3][4] Egypt, France, India, Jordan, Mexico, Morocco, Niger, Nigeria, Romania, Tunisia, United States (Arizona, Colorado, New Mexico, Texas), and Venezuela.
