Orthoceras ("straight horn") is a genus of extinct nautiloid cephalopod restricted to Middle Ordovician-aged marine limestones of the Baltic States and Sweden.[1] This genus is sometimes called Orthoceratites. Note it is sometimes misspelled as Orthocera, Orthocerus or Orthoceros (Sweet 1964:K222).

Orthoceras was formerly thought to have had a worldwide distribution due to the genus' use as a wastebasket taxon for numerous species of conical-shelled nautiloids throughout the Paleozoic and Triassic. Now, Orthoceras sensu stricto refers to O. regulare, of Ordovician-aged Baltic Sea limestones of Sweden and neighboring areas.[1]

These are slender, elongate shells with the middle of the body chamber transversely constricted, and a subcentral orthochoanitic siphuncle. The surface is ornamented by a network of fine lirae (Sweet 1964:K224). Many other very similar species are included under the genus Michelinoceras.

Please each item's description and examine all photos well. Click on the photos and expand. The photos are to be considered a very important part of the description.

If this item is listed as used or pre-owned, there will likely be signs of use and age throughout its entirety. Pay special attention to areas such as: leather, handles, handle bases, canvas, interior, exterior, edges, zippers, pockets, corners, hardware: scuffs, scratches, tarnishing.

Regarding Patent and Vernis Leather: There may be small scuffs, scratches, color transfer, ect that does not show well in the photographs. Although we will do our best to photograph each item well, there is the possibility of small inconsistencies that are not visible in the photos. Please be aware of this.
Regarding Jewelry Please pay close attention to the size. Please measure your own fingers, neck, body parts before purchase, and/or be prepared to have it sized larger or smaller at a jeweler. Jewelry returns will not be accepted due to improper fit.

Please keep in mind the that descriptors such as “good,” or “very good” are subjective- your opinion may differ from mine. In my case, an item may be in “good condition," as I am considering its age and its particular style.”
*Please Note: Unless stored in a vacuum, it is a fact that time naturally ages materials such as leather, cloth, and metal. Be careful when dealing with anyone selling a vintage item that they state is in "perfect" or "brand new" condition.
    A large majority of the items for sale have been previously owned. This means that most items will not include the original packaging. Unless the item description states otherwise, is best to assume that packaging and accessories such as: box, bag, dust bag, receipt, lock, key, fobs, cloche, card, papers, tags, ect. will not be included. The item for sale will be described in the listing.

    Please keep in mind that the majority of our items are previously owned and/or vintage. We always do our best to report any unusual pre-existing odors in every listing (storage, closet, perfume, smoke, ect). However, you must keep in mind, that because these items are pre-owned, they may ultimately have some type of smell that may be unnoticeable to us, but is noticeable to you because it is different from your own personal scent. Over time, that will change. Over time, every item will eventually begin to smell just like you do.

    Please ask any questions prior to purchase.
