The Phacops rana, a species of trilobite, became extinct during the end-Devonian mass extinction, which was likely caused by a combination of climate change, volcanic activity, and a drop in sea levels. These environmental changes likely disrupted the trilobite's habitats and food sources, leading to their extinction.
The trilobite is a famous Palaeozoic marine creature that lived around 540 to 250 million years ago. These arthropods were among the most successful and diverse animal groups of their time, with numerous species ranging in size, shape, and habitat. Trilobites left behind an extensive fossil record that provides valuable insights into Earth's ancient marine ecosystems.
The exoskeleton composition did not change through time in trilobites. Trilobites maintained a calcite exoskeleton throughout their existence in the fossil record.
The omasium is a part of an extinct group of organisms called trilobites. It refers to a region of the cephalon (head) that lies between the glabella and the lateral border or furrow. The omasium is used for classification purposes in trilobite taxonomy.
Trilobites existed for about 270 million years, from the Early Cambrian period to the end of the Permian period, before becoming extinct around 250 million years ago. Each species had its own lifespan, but on average, trilobites lived for a few years to several decades, depending on the species and environmental conditions.
