Sibiritidae

The Sibiritidae is a family of ceratitid ammonites previously included in the Noritaceae, but now in the Ceratitaceae known from the lower and middle Triassic. Shells tend to be evolute, with all whorls exposed, stout, rounded in section, and strongly ribbed.

Originally the Sibiritidae included such genera as Sibirites, Wasatchites, Keyserlingites, and Olenikites to which others like Goricanites, Monacanthites, and Timoceras were later added.

In some more recent classifications the Sibiritdae includes the subfamilies Keyserlingitinae, Olenikitinae, and Silberlingitinae.
