Discocone ornamented ribbing pattern I 3D print model

Name of the model: Discocone Conch OrnamentedTriangles: 1285354Vertices: 642679Information: This model emulates an almost oxyconic conch known as discocone withornamentation (ribs of three orders). In oxycones the umbilicus is not well exposed, and theoverall shell form is compressed. According to Westermann (1996) the whorl height showspronounced expansion during accretion of the recent 180° of shell whorl. Oxycones would haveoffered higher stability and maneuverability than other forms, and generally a short bodychamber.References:Westermann GEG. 1996. Ammonoid Life and Habitat.
