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]
Description[]
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. The earliest whorls are smooth except for periodic constrictions; later juvenile whorls have numerous low ribs without tubercles.
Taxonomy[]
Neoptychites belongs to the ammonite family Vascoceratidae and is included in the subfamily Vasoceratinae. The genus was named by Kossmat in 1895. Its type species is Ammonites telinga Stoliczka, 1865 (= Ammonites cephalotus Courtiller, 1860). It is probably derived from .
Distribution[]
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.[1]
