Ammonite Hophites or Daghestanites is a genus of ammonite that lived from the Early Albian to the beginning of the Middle Albian. Its fossils have been found in Europe, Transcaspia and Mexico.
Ammonite Hophites or Daghestanites shell has compressed, rectangular till depressed and trapezoidal whorl section. There are strong umbilical bullae from which, prominent ribs are branching and these are interrupted on venter. Ends of ribs on the venter are prominent and can be both alternate or opposite.
Some Ammonite Hophites or Daghestanites species have zigzaging ribs and these ribs ends usually thickened, or they can be raised into ventrolateral tubercules. These tubercules are mostly oblique clavi.
Ammonite Hophites or Daghestanites first appeared in the early Devonian period. They evolved from a small, straight shelled Bactridian, which was an early Nautiloid. They quickly evolved into a variety of shapes and sizes, including some shaped like hairpins.
Ammonites or Daghestanites were sea creatures that were close relatives of today’s octopuses and squids, except they lived inside shells. The shell consisted of mineral aragonite, a shiny mineral that pearls are also made from.
As the Ammonites or Daghestanites grew, they added new chambers to their shell, which formed a spiral. The hollow inner chambers of the shell provided oxygen and helped them to float in the ocean.
Ammonities or Daghestanites lived throughout the seas and swam by squirting water in one direction, pushing themselves along the sea floor. Ammonities appeared 425 million years ago and were very common ocean animals. They died out approximately 66 million years ago.
On the inside of the shell, the compartments are marked by elaborate sutures. These can be seen easily on those fossils which are internal moulds, as most are.
Ammonites or Daghestanites were active predators, and they themselves were often eaten by fish and marine reptiles. The fossils are almost always found with the outer compartment broken off, probably as a result of just such an attack.
