Oxicone海螺装饰 3D模型

Name of the model: " Oxicone Conch Ornamented" Triangles: 2272784 Vertices: 1136388 Size: 108 MB Information: This model emulates an oxyconic conch with ornamentation (sinuous and intercalar ribs). In oxycones the umbilicus is not well exposed, and the overall shell form is compressed. According to Westermann (1996) the whorl height shows pronounced expansion during accretion of the recent 180 of shell whorl. Oxycones would have offered higher stability and maneuverability than other forms, and generally a short body chamber. References: Westermann GEG. 1996. Ammonoid Life and Habitat.
