Engorthoceras Flower, 1962 |
Engorthoceratidae is a small family of Devonian orthocerids and a class of cephalopod found in eastern North America ( Ohio and Indiana), containing only the genus Engorthoceras. [1] [2]
Engorthoceratidae was named in 1962 by Rousseau Flower to contain the genus Engorthoceras, also named by Flower (1962), and assigned to the Michelinceratida. The genotype is Orthoceras worthoni. [1]
Engorthoceras produced straight conical shells with a subcircular cross section and a small completely marginal siphuncle. [1] The conical shell is suggestive of belemnite phragmocones and of its possible ancestry to Eobelemites. Nothing is known of the animal itself.
