Mcqueenoceras

Mcqueenoceras was an ancient group of sea creatures that lived long ago during a time called the Floian epoch. It belonged to a family of animals known as endocerids, similar to modern nautiloids. Mcqueenoceras looked much like another creature called [Clitendoceras](/wiki/Clitendoceras), but it had some special features. The inside of its shell, called the siphuncle, was thicker on one side. Also, the lines where its shell sections joined would bend at the edges.

The main species of Mcqueenoceras is called Mcqueenoceras jeffersonense. It was first described by scientists in 1935. Fossils of this creature have been found in places like Missouri and New York. Later, in 1956, another scientist added two more species to this group, called M. cariniferum and M. ventrale. These were discovered in Maryland. These fossils help us learn about life in the ancient seas.
