Clymeniida
Clymeniida is an order of ammonoid cephalopods from the Upper Devonian characterized by having an unusual dorsal siphuncle. They measured about in diameter and are restricted to Europe, North Africa, and possibly Australia. Morphologic characteristics Clymeniids produced a variety of shells ranging from smooth to ribbed and spinose and from evolute with all whorls exposed to strongly involute with the last whorl covering the previous. Some were even triangular as viewed from the side (along the axis of coiling). With the exception of the first few chambers, all have a siphuncle that runs along the dorsal margin, along the inside of the coils, opposite that of most ammonoids. The siphuncle starts off ventrally, like that in other ammonoids, but after the first few septa migrates to a definite and stable dorsal position. Septal necks are retrosiphonate, characteristic of their nautiloid ancestors, and are commonly very long, forming an almost continuous siphuncular tube. Sept ...

Erfoud
Erfoud ( ber, ⴰⵔⴼⵓⴷ, Latn, ber, Arfud; ar, أرفود) is an oasis town in the Sahara Desert, in the Drâa-Tafilalet region, eastern Morocco. It is divided into several districts: Hay Salam, Hay Jdid, Hay Ziz, Hay el Bathaa, Hay Annahda, and Hay el Hamri. Due to its proximity to Merzouga desert village in the Erg Chebbi Dunes, Erfoud has developed tourist-related infrastructures such as hotels and restaurants. Filming location Erfoud is a destination for filmmakers due to the beauty of the surrounding Sahara Desert and the town's oasis areas. Erfoud has been a filming location for many films, including: *'' March or Die'' (1977) :In the film archeologists are uncovering an ancient city near Erfoud buried by a sand storm 3,000 years ago. The site is the resting place of a Berber saint, "The Angel of the Desert". *''The Mummy'' (1999) :Filming began in Marrakech, Morocco on May 4, 1998 and lasted 17 weeks. Photography then moved to the Sahara Desert outside Erfou ...

Famennian Extinctions
The Famennian is the latter of two faunal stages in the Late Devonian Epoch. The most recent estimate for its duration estimates that it lasted from around 371.1 million years ago to 359.3 million years ago. An earlier 2012 estimate, still used by the International Commission on Stratigraphy, estimated that it lasted from million years ago to million years ago. It was preceded by the Frasnian stage and followed by the Tournaisian stage. Major events In the seas, a novel major group of ammonoid cephalopods called clymeniids appeared, underwent tremendous diversification and spread worldwide, then just as suddenly went extinct. The beginning of the Famennian is marked by the final stages of a major extinction event, the Kellwasser Event, which is the largest component of the Late Devonian Mass extinction. The end of the Famennian experiences a smaller but still quite severe extinction event, the Hangenberg Event. A brief episode of glaciation, possibly linked to the Han ...
