Top view of a fragment of internal mold of a straight, conical shell, broken lengthwise.

Exact range unknown, thought to be entire Cincinnatian. <\/li>\n<\/ul>\n<p><em>McFarlan (1931) <\/em>: <\/p>\n<ul>\n<li><em>E. proteiforme<\/em> is characterized by its enormous size, sometimes attaining a length of 10-15 feet, circular section, comparatively shallow chambers, and large submarginal siphon. The spacing of the septa increases toward the body chamber. Relative diameters of the shell and siphuncle in available specimens about 2:1. A wide-spread and common species throughout the Mohawkian and Cincinnatian.\n<\/li>\n<\/ul>\n<p><em>Hall (1847) <\/em>: <\/p>\n<ul>\n<li>General from cylindrico-conical, more or less elongated, often compressed, tapering somewhat unequally in different specimens; young specimens terminating in an extremely acute point; surface marked by distinct transverse striae, which usually appear like narrow subimbricating bands, with one edge well defined and more elevated than the other, more or less distinctly striated longitudinally, striae varying from extreme tenuity to distinct elevated threadlike lines; section circular; septa distant from one fifth to one fourth the diameter; siphuncle eccentric or submarginal. <\/li>\n<li>I am able to characterize three distinct varieties of this species, which are the prevailing forms: these depend mainly on the surface marking of the young shell. The old shells are recognized by a large submarginal siphuncle, which usually contains a smooth cylindricoconical embryo tube or sheath. This tube is sometimes irregularly tapering, and always free from visible surface markings or sculpture. Within this embryo tube are the young shells, sometimes perfectly formed <em>Orthocerata<\/em> and at other times destitute of septa or siphuncle. These young shells are also frequently found separate from the parent shell or embryo tube, when we are compelled to rely upon the surface markings for their determination. The position of the siphuncle, convexity of septa, and some other characters, are usually constant in all the varieties, which only exhibit a change in the character of the surface.  In the absence of septa and siphuncle, which is of common occurrence in the young shell, the character of the surface is reliable for determining the species. <\/li>\n<\/ul>\n<p>[\/accordion] [\/accordions]<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Classification Phylum: Mollusca Class: Cephalopoda Order: Endocerida Family: Endocertidae Genus: Endoceras Species: Endoceras proteiforme (Hall, 1847) [accordions title=&#8221;&#8221; disabled=&#8221;false&#8221; active=&#8221;1&#8243; autoheight=&#8221;false&#8221; collapsible=&#8221;true&#8221;] [accordion title=&#8221;Taxonomic Details&#8221;] [\/accordion] [\/accordions] Stratigraphic Occurrences Geographic Occurrences Map point data provided by iDigBio.
