Meaning of "nautiloid" in English

"Nautiloid" refers to a subclass of marine cephalopods belonging to the class Cephalopoda, which also includes squids and octopuses. Nautiloids are distinguished by their external shells, which are typically coiled, although some species have straight shells. They were once the dominant predators in the ocean and are characterized by eight to over ninety arms with no suckers. Today, the only surviving genus is Nautilus, which can easily be identified by its distinctive shell. These creatures are often used in paleontological studies to understand prehistoric marine ecosystems.

Meaning of "orthocère" in French

"Orthocère," or Orthoceras in scientific terms, refers to a genus of the extinct nautiloid cephalopods, primarily found in marine limestone deposits from the Paleozoic era. These were straight-shelled nautiloids that thrived during the Ordovician Period. The orthocères played a significant role in marine ecosystems, with their fossilized shells often serving as a valuable tool for geologists and paleontologists to date rock strata and reconstruct ancient environments. They offer insights into early cephalopod evolution and diversity, contributing to the understanding of extinct marine life.
