Domäänides

Domäänides are a genus of extinct marine mollusks that belonged to the class Cephalopoda. They are known from fossil records dating back to the Late Jurassic period. The genus is characterized by their coiled, planispiral shells, which exhibit a range of size and ornamentation features.

Members of the domäänides are considered part of the family Hecticoceratidae, within the order Ammonitida. Their shells typically display ribbed or smooth surfaces, and the sutures between shell chambers tend to be simple or faintly ruffled. The aperture of the shell is generally rounded, and the shells often have a well-defined keel or ventral rim, aiding in their identification.

Domäänides were marine animals that inhabited the ancient oceans and are believed to have been free-swimming predators. They likely preyed upon smaller marine organisms, contributing to the complex marine ecosystems of their time.

Fossils of domäänides have been discovered in various locations around Europe and Asia, providing important insights into the diversity and evolutionary history of ammonoid cephalopods during the Jurassic period. Their fossils are valuable for biostratigraphic dating, helping geologists to correlate the ages of sedimentary rock layers within the Paleogene marine deposits.

Overall, domäänides contribute to our understanding of cephalopod evolution and the marine life of the Mesozoic era. Ongoing discoveries continue to shed light on their morphological variations, ecological roles, and evolutionary relationships within the ammonite group.
